The management of fractures of the medial epicondyle is one of the greatest controversies in paediatric fracture care, with uncertainty concerning the need for surgery. The British Society of Children’s Orthopaedic Surgery prioritized this as their most important research question in paediatric trauma. This is the protocol for a randomized controlled, multicentre, prospective superiority trial of operative fixation versus nonoperative treatment for displaced medial epicondyle fractures: the Surgery or Cast of the EpicoNdyle in Children’s Elbows (SCIENCE) trial. Children aged seven to 15 years old inclusive, who have sustained a displaced fracture of the medial epicondyle, are eligible to take part. Baseline function using the Patient-Reported Outcomes Measurement Information System (PROMIS) upper limb score, pain measured using the Wong Baker FACES pain scale, and quality of life (QoL) assessed with the EuroQol five-dimension questionnaire for younger patients (EQ-5D-Y) will be collected. Each patient will be randomly allocated (1:1, stratified using a minimization algorithm by centre and initial elbow dislocation status (i.e. dislocated or not-dislocated at presentation to the emergency department)) to either a regimen of the operative fixation or non-surgical treatment.Aims

LIMB-Q Kids is a new patient-reported outcome measure (PROM) for children with Lower limb differences (LLDs). The objective is to conduct an international field test study. A mixed method multiphase approach was used to develop LIMB-Q Kids. In phase one, a systematic review was conducted to identify concepts from existing PROMs used in research with children with LLDs. A preliminary conceptual framework derived from the systematic review informed an international qualitative study. The data from qualitative interviews were used to form the LIMB-Q Kids, which was further refined through multiple rounds of cognitive debriefing interviews with children. Input was obtained from parents and healthcare professionals from Australia, Canada, Ethiopia, India, UK, and the USA. LIMB-Q Kids was translated and culturally adapted into multiple languages.Introduction

The FitBone lengthening nail (Orthofix UK) is an intramedullary device licensed for the lengthening of long bones in adults in the UK. It contains a motor powered by electricity transmitted via an induction coil placed underneath the skin. It was developed in Germany two decades ago but uptake in the UK has only started more recently. The aim of this study was to review the first cohort of FitBone lengthening nails in a unit with significant experience of other lengthening nails (including PRECICE and Stryde). Demographic, clinical and radiological data was prospectively collected on all FitBone cases starting in February 2022. Accuracy of lengthening rate, patient satisfaction and implant issues were all considered. Complications and learning points were recorded and discussed by the multidisciplinary team involved in the patients care.Introduction

Adjusting an external fixator can be a daunting process for patients. Despite comprehensive training, patients often request supervision for the initial adjustments which may result in a prolonged hospital stay. Following the introduction of telemedicine during the pandemic we believed that this could be utilised to support patients with their fixator adjustments. A quality improvement project was implemented to assess and evaluate a change in practice from existing Face to Face support to a telemedicine format. The aim of the project was to reduce median length of stay (LOS). The telemedicine platform was introduced in our unit from April 2021 with the change in practice. Using the life QI platform, run charts were used to record the numbers of patients whose LOS was 4 days or less. Median LOS was assessed prior to and following introduction of the telemedicine platform. Service user experience with telemedicine as well as overall training and education by the CNS team was sought through on-line questionnaires.Introduction

A greater emphasis has been placed on fracture related infection (FRI) orthopaedic practice as a separate entity in recent years. Since the publication of the FRI consensus definition and guidelines, there has been an increase in the published literature on the topic and a move towards considering FRI as separate from general orthopaedic practice and as work that requires a more specialist approach. The aim of this study was to audit current FRI practice in the UK. Orthopaedic practice related to FRI in the UK was audited using a semi-structured questionnaire. Respondents were from a range of institutions, specialties and clinical roles to reflect the multi-disciplinary nature of treating FRI. The online tool SurveyMonkey was used to share the survey at the 2022 annual meeting of the British Limb Reconstruction Society. Twenty-one questions were asked in the following domains: scope of practice, theatre and clinic capacity, availability of the multidisciplinary team, renumeration for work and scope of FRI networks.Introduction

Dislocation following total hip arthroplasty (THA) is a well-known and potentially devastating complication. Clinicians have used many strategies in attempts to prevent dislocation since the introduction of THA. While the importance of postoperative care cannot be ignored, particular emphasis has been placed on preoperative planning in the prevention of dislocation. The strategies have progressed from more traditional approaches, including modular implants, the size of the femoral head, and augmentation of the offset, to newer concepts, including patient-specific component positioning combined with computer navigation, robotics, and the use of dual-mobility implants. As clinicians continue to pursue improved outcomes and reduced complications, these concepts will lay the foundation for future innovation in THA and ultimately improved outcomes. Cite this article:
While metagenomic (microbial DNA) sequencing technologies can detect the presence of microbes in a clinical sample, it is unknown whether this signal represents dead or live organisms. Metatranscriptomics (sequencing of RNA) offers the potential to detect transcriptionally “active” organisms within a microbial community, and map expressed genes to functional pathways of interest (e.g. antibiotic resistance). We used this approach to evaluate the utility of metatrancriptomics to diagnose PJI and predict antibiotic resistance. In this prospective study, samples were collected from 20 patients undergoing revision TJA (10 aseptic and 10 infected) and 10 primary TJA. Synovial fluid and peripheral blood samples were obtained at the time of surgery, as well as negative field controls (skin swabs, air swabs, sterile water). All samples were shipped to the laboratory for metatranscriptomic analysis. Following microbial RNA extraction and host analyte subtraction, metatranscriptomic sequencing was performed. Bioinformatic analyses were implemented prior to mapping against curated microbial sequence databases– to generate taxonomic expression profiles. Principle Coordinates Analysis (PCoA) and Partial Least Squares-Discriminant Analysis were utilized to ordinate metatranscriptomic profiles, using the 2018 definition of PJI as the gold-standard.Aim

Single-event multilevel surgery (SEMLS) is the standard orthopaedic treatment for gait abnormalities in children with diplegic cerebral palsy (CP). The primary aim of this study was to report the long-term functional mobility of these patients after surgery. The secondary aim was to assess the relationship between functional mobility and quality of life (QoL). Patients were included if they met the following criteria: 1) diplegic CP; 2) Gross Motor Function Classification System (GMFCS) I to III; 3) SEMLS at age ≤ 18. A total of 61 patients, mean age at surgery 11 years eight months (SD 2y 5m), were included. A mean of eight years (SD 3y 10m) after SEMLS, patients were contacted and asked to complete the Functional Mobility Scale (FMS) questionnaire over the telephone and given a weblink to complete an online version of the CP QOL Teen. FMS was recorded for all patients and CP QOL Teen for 23 patients (38%).Abstract

Patients undergoing limb reconstruction surgery often face a challenging and lengthy process to complete their treatment journey. The majority of existing outcome measures do not adequately capture the patient-reported outcomes relevant to this patient group in a single measure. Following a previous systematic review, the Stanmore Limb Reconstruction Score (SLRS) was designed with the intent to address this need for an effective instrument to measure patient-reported outcomes in limb reconstruction patients. We aim to assess the face validity of this score in a pilot study. The SLRS was designed following structured interviews with several groups including patients who have undergone limb reconstruction surgery, limb reconstruction surgeons, specialist nurses, and physiotherapists. This has subsequently undergone further adjustment for language and clarity. The score was then trialled on ten patients who had undergone limb reconstruction surgery, with subsequent structured questioning to understand the perceived suitability of the score.Aims

The aim of this study was to present the first retrieval analysis findings of PRECICE STRYDE intermedullary nails removed from patients, providing useful information in the post-market surveillance of these recently introduced devices. We collected ten nails removed from six patients, together with patient clinical data and plain radiograph imaging. We performed macro- and microscopic analysis of all surfaces and graded the presence of corrosion using validated semiquantitative scoring methods. We determined the elemental composition of surface debris using energy dispersive x-ray spectroscopy (EDS) and used metrology analysis to characterize the surface adjacent to the extendable junctions.Aims

The STRYDE nail is an evolution of the PRECICE Intramedullary Limb Lengthening System, with unique features regarding its composition. It is designed for load bearing throughout treatment in order to improve patient experience and outcomes and allow for simultaneous bilateral lower limb lengthening. The literature published to date is limited regarding outcomes and potential problems. We report on our early experience and raise awareness for the potential of adverse effects from this device. This is a retrospective review of prospective data collected on all patients treated in our institution using this implant. We report the demographics, nail accuracy, reliability, consolidation index, and cases where concerning clinical and radiological findings were encountered. There were 14 STRYDE nails implanted in nine patients (three male and six female) between June 2019 and September 2020. Mean age at surgery was 33 years (14 to 65). Five patients underwent bilateral lengthening (two femoral and three tibial) and four patients unilateral femoral lengthening for multiple aetiologies.Aims
Methods
The use of intramedullary lengthening devices is becoming increasingly popular. There are no published data regarding the incidence of venous thromboembolism following intramedullary lengthening and no reports or guidance for current practices on use of thromboprophylaxis. Following a case of post-operative deep vein thrombosis in our institution, we felt that it is important to assess best practice. We conducted this survey to collect data that would describe current practice and help guide consensus for treatment. We have identified surgeons across the UK that perform intramedullary lengthening through the British Limb Reconstruction Society membership and a Precise Users database. Surgeons were contacted and asked to respond to an online survey (SurveyMonkey - SVMK Inc.). Responses to thromboprophylaxis regimes employed in their practice and cases of venous thromboembolism were collated.Introduction

Leg length discrepancy (LLD) in patients with unilateral developmental dysplasia of the hip (DDH) can be problematic for both patients and surgeons. Patients can acquire gait asymmetry, back pain, and arthritis. Surgical considerations include timing of correction and arthroplasty planning. This study audits standing long leg films performed at skeletal maturity in our patients. The aim of this study is to identify if surgical procedure or AVN type could predict the odds of needing an LLD Intervention (LLDI) and influence our surveillance. Hospital database was searched for all patients diagnosed with DDH. Inclusion criteria were patients with appropriately performed long leg films at skeletal maturity. Exclusion criteria were patients with non DDH pathology, skeletally immature and inadequate radiographs. All data was tabulated in excel and SPSS was used for analysis. Traumacad was used for measurements and AVN and radiologic outcome grades were independently classified in duplicate.Introduction

Pixel Value Ratio (PVR) is a radiographic measure of the relative density of the regenerate to the adjacent bone. This has been reported as an objective criterion for regenerate healing and a guide for when to allow full weight bearing (FWB) in lengthening with intramedullary telescopic nails. The threshold for which magnitude of PVR is adequate to allow bearing full weight is not yet agreed. The aim of this study was to identify from our cohort of adult limb lengthening patients the time to FWB following lengthening, the PVR at this point, and how this compared with the recommended values in the literature. A retrospective database review identified 30 adult patients treated with the PRECICE femoral nail by two senior authors. Time from completion of lengthening to instruction to fully weight bear was noted. The PVR was calculated for each cortex on plain radiographs taken at each postoperative visit following completion of lengthening. Significance was set at Introduction

Ring breakage is a rare but significant complication requiring revision surgery and prolonging the course of treatment. We have encountered three cases with Taylor Spatial Frames (TSF) with breakage at the half ring junction of the distal ring. This experimental study examines the strains produced at different locations on the distal ring during loading and the effects of altering the construct in order to develop techniques to minimise the risk of breakage. We mounted different TSF constructs on tibia sawbone models. Construct 1 reproducing the configuration of cases where failure was seen, Construct 2 with different wire and half pin configuration and construct 3 with the distal ring rotated 60 degrees. Strain Gauges were attached to different locations and measurements were collected during loading. Statistical analysis was subsequently performed.Introduction

Pin-tract infections are a common problem in orthopaedic surgery, which limits the time an external fixator or Taylor spatial frame can be applied to a patient. The purpose of our study is to evaluate the ability of a novel implant surface coating — cationic steroid antibiotic (CSA)-44 — to delay or prevent the onset of these infections. This coating mimics endogenous antimicrobial peptides of the innate immune system and has been shown to effectively eradicate biofilms as well as prevent infection and stimulate healing of open, contaminated fractures. Surgeries were performed on 20 animals (outbred; Sprague-Dawley strain rats). Each animal received both CSA-coated and standard-of-care titanium pins, with pins randomized to the fifth or sixth vertebrae prior to surgeries. Animals were also randomized to either “Imaging” (imaging analysis) or “Infection” (microbiological analysis) cohorts. Surgeons were blinded to pin types and analyses cohorts. Digital images of pin sites were collected weekly over 12 weeks, and then graded by two orthopaedic surgery residents according to an established Likert scale. Graders were blinded to animal numbers, pin types, and timepoints (Figure 1). For the infection analysis cohort, four specimens per site were subjected to microbiological analysis from each site (i.e. pin, superficial skin swab, deep skin swab, sonicated bone). Each specimen was processed on three different microbiological plates (i.e. BAP, CAN, MAC) using standardized techniques. Imaging analysis was performed by dissecting vertebrae Introduction

Follow-up of arthroplasty varies widely across the UK. The aim of this NIHR-funded study was to employ a mixed-methods approach to examine the requirements for arthroplasty follow-up and produce evidence-based and consensus-based recommendations. It has been supported by BHS, BASK, BOA, ODEP and NJR. Four interconnected work packages have recently been completed: (1) a systematic literature review; (2a) analysis of routinely collected National Health Service data from four national data sets to understand when and which patients present for revision surgery; (2b) prospective data regarding how patients currently present for revision surgery; (3) economic modelling to simulate long-term costs and quality-adjusted life years associated with different follow-up care models and (4) a Delphi-consensus process, involving all stakeholders, to develop a policy document to guide appropriate follow-up care after primary hip and knee arthroplasty.
For ODEP10A∗ minimum implants, it is safe to disinvest in routine follow-up from 1 to 10 years post non-complex hip and knee replacement provided there is rapid access to orthopaedic review For ODEP10A∗ minimum implants in complex cases, or non-ODEP10A∗ minimum implants, periodic follow-up post hip and knee replacement may be required from 1 to 10 years At 10 years post hip and knee replacement, we recommend clinical, which may be virtual, and radiographic evaluation After 10 years post hip and knee replacement, frequency of further follow-up should be based on the 10-year assessment; ongoing rapid access to orthopaedic review is still required These recommendations apply to post primary hip and knee replacement follow-up The 10-year time point in these recommendations is based on a lack of robust evidence beyond ten years The term complex cases refer to individual patient and surgical factors that may increase the risk for replacement failure
Overarching statements
Little is known about the relationship between head-neck corrosion and its effect on periprosthetic tissues and distant organs in the majority of patients hosting apparently well-functioning devices. We studied the degree and type of taper damage and the histopathologic response in periprosthetic tissue and distant organs. A total of 50 contemporary THRs (34 primary, 16 revision) retrieved postmortem from 40 patients after 0.4–26 years were studied. Forty-three femoral stems were CoCrMo and 7 were Ti6Al4V. In every case, a CoCrMo-alloy head articulated against a cementless polyethylene cup (19 XLPE and 31 UHMWPE). H&E and IHC sections of the joint pseudocapsules and liver were graded 1–4 for the intensity of various inflammatory cell infiltrates and tissue necrosis. The nature of the tissue response in the joint capsule, liver, spleen, kidneys and lymph nodes was assessed. Wear and corrosion products in the tissues were identified using SEM and EDS. Taper surfaces were graded for corrosion damage using modified Goldberg scoring and examined by SEM to determine the acting corrosion mode. Correlations between damage scores and the histologic variables were generated using the Spearman test.Introduction

To quantify the micro-motion at the fracture gap in a tibial fracture model stabilised with an external fixator. A surrogate model of a tibia and a cadaver leg were fractured and stabilised using a two-ring hexapod external fixator. They were tested initially under static loading and then subjected to vibration.Aim

There is an ongoing revolution in the use of data within orthopaedics and medicine in general, with an imperative for surgeons to be involved from the bottom up and better define the data collection culture. The use of registries plays a major role in the development of “big data” in orthopaedics. There are multiple examples that are already set up and running, both those inspired and set up by clinicians or those where the main stakeholders may lay people, with some input from clinicians. The British Limb Reconstruction society is no exception, with registries for lengthening nails and pilon fractures due to roll out imminently. The BLRS has tasked this years BOA clinical leadership fellow to investigate the current state of registries among the specialist orthopaedic societies. In particular, comparison of the already well established registries and national audits with the development of registry projects in the smaller societies. The issues of funding, consent, infrastructure and governance each infer particular challenges when translating the methods of the larger registries to the needs and resources of a smaller group. We have aimed to consider these challenges in relation to the set-up of the BLRS registries in order to better understand the potential future pitfalls and opportunities.
To review the natural history of posteromedial bowing of the tibia and the outcome of limb reconstruction in this condition. 38 patients with posteromedial bowing of the tibia presenting between 2000–2016 were identified. Mean follow up from presentation was 78 months. Seventeen patients underwent lengthening and deformity correction surgery, whilst 3 further patients are awaiting lengthening and deformity correction procedures.Purpose
Patients and Methods
Severe infantile Blount's disease can result in a multiplanar deformity of the proximal tibia with both intra-articular and metaphyseal components. Correction can represent a significant surgical challenge. We describe our results using the Taylor spatial frame for acute tibial hemiplateau elevation combined with gradual metaphyseal correction in patients with severe infantile blounts with an associated physeal bony bar. Eight patients (10 knees) underwent tibial hemiplateau elevation and metaphyseal correction with use of the Taylor Spatial Frame between 2012–2016. We undertook a retrospective case note and radiographic review of all patients to assess clinical and radiographic outcomes. Mean age at the time of surgery of was 11.7 years and mean length of follow up was 16.8 months.Background

This study aims to evaluate the development of deformity in patients with hypophosphataemic rickets and the evolution of the orthopaedic management thereof. Fifty-four patients had undergone treatment for hypophosphataemic rickets at our institution since 1995. Clinical records for all patients were obtained. Forty-one patients had long leg radiographs available that were analysed using Traumacad™ software. Statistical analysis was performed using SPSS 23 (SPSS Inc., Chicago, Illinois, USA). Of the 41 patients, 18 (43%) had no radiographic deformity. 20 have undergone bilateral lower limb surgery for persistent deformity (Mechanical Axis ≥ Zone 2). A further 3 patients are awaiting surgery. Six patients (12 limbs, 14 segments) had osteotomies and internal fixation as primary intervention: only one limb developed recurrent deformity. There were no major complications. Fourteen patients (28 limbs) had 8-plates (Orthofix, Verona) applied. In 5 limbs correction is on-going. Neutral alignment (central Zone 1) was achieved in 14/20 (70%) patients. Two patients required osteotomy and external fixation for resistant deformity. The mean rate of angular correction following 8-plate application was 0.3 and 0.7 degrees/month for the tibia and femur respectively. The mean age at 8-plate insertion was 10.25y (5–15y). Patients with more than 3 years of growth remaining responded significantly better than older patients (Fisher Exact Test, p=0.024). Guided growth was more successful in correcting valgus deformity than varus deformity (Fisher Exact Test, p=0.04). In the younger patients, diaphyseal deformity corrected as the mechanical axis improved at the rate of 0.2 and 0.7 degrees /month for the tibial and femoral shafts. Serum phosphate and alkaline phosphatase levels did not affect response to surgery or complication rate. Guided growth by means of 8-plates is a successful in addressing deformity in hypophosphataemic rickets. Surgery is best performed in patients with more than 3 years of growth remaining.
Children with congenital vertical talus (CVT)
have been treated with extensive soft-tissue releases, with a high
rate of complications. Recently, reverse Ponseti-type casting followed
by percutaneous reduction and fixation has been described, with
excellent results in separate cohorts of children with CVT, of either
idiopathic or teratological aetiology. There are currently no studies
that compare the outcome in these two types. We present a prospective cohort
of 13 children (21 feet) with CVT of both idiopathic and teratological
aetiology, in which this technique has been used. Clinical, radiological
and parent-reported outcomes were obtained at a mean follow-up of
36 months (8 to 57). Six children (nine feet) had associated neuromuscular
conditions or syndromes; the condition was idiopathic in seven children
(12 feet). Initial correction was achieved in all children, with significant
improvement in all radiological parameters. Recurrence was seen
in ten feet. Modification of the technique to include limited capsulotomy
at the initial operation may reduce the risk of recurrence. The reverse Ponseti-type technique is effective in the initial
correction of CVT of both idiopathic and teratological aetiology.
Recurrence is a problem in both these groups, with higher rates
than first reported in the original paper. However, these rates
are less than those reported after open surgical release. Cite this article:
Congenital vertical talus (CVT) is a rare deformity of the foot. It has been historically treated with extensive soft tissue releases with significant associated complications. Recently, reverse Ponseti-type casting followed by minimally invasive or percutaneous reduction and fixation has been described with excellent results in separate cohorts of either idiopathic or teratologic cases of CVT. There are currently no studies that compare the outcomes between the two types. We present a prospective cohort of 13 patients (21 feet) in which this technique has been used in both idiopathic and teratologic associated cases of CVT. Clinical, radiographic and parent-reported outcomes were obtained at a mean follow up of 36 months (range 8–57). Clinical and radiographic scoring was according to the system of Adelaar and parent-reported outcomes were assessed using the POSNA paediatric outcomes data collection instrument (PODCI).Background

Identification of the paediatric orthopaedic patient at high risk of venous thromboembolism (VTE) can allow a targeted approach to thromboprophylaxis. There is currently no national consensus on the correct method of risk assessment in this patient group. The Royal National Orthopaedic Hospital has developed a guideline using the evidence available to allow stratification of risk for the paediatric orthopaedic patient. A list of departments offering specialist paediatric orthopaedic surgery was obtained from the member list of the British Society of Paediatric Orthopaedic Surgeons (BSCOS). These hospitals were contacted via telephone interview to determine if they have a specific guideline or risk assessment proforma for paediatric VTE risk. A total of 74 hospitals were identified with a specialist paediatric orthopaedic practice in the United Kingdom. A response rate was gained from 100% of these hospitals. Only 3/74 of these hospitals had a guideline or protocol in place for the formal assessment of VTE risk in the paediatric patient (Royal National Orthopaedic Hospital, Stanmore; Sheffield Children's Hospital; Barts & the London NHS Trust). All three hospitals were able to provide details of their guideline. Both the RNOH and Barts & the London commented that their guideline was based on that of the Sheffield group, with adaptations for their own requirements. The majority of hospitals in the UK with a paediatric orthopaedic interest do not have guidance available for the management of VTE risk. Presented here is the outcome of using the limited evidence available, in combination with expert opinion, to develop a guideline suitable for the requirements of a paediatric unit in an orthopaedic hospital. This may be of benefit to other units producing their own guidelines, producing thought and discussion as to the specific requirements of paediatric patients undergoing orthopaedic procedures.
The use of intraoperative cell salvage as a tool for reducing allogenic transfusion has been demonstrated in pelvic osteotomies. The aims of this audit were to identify any problems or complications with cell salvage, reduction in allogenic transfusion and identify procedures that would benefit. The use of cell salvage and allogenic transfusions were prospectively recorded over a 27-month period for all those who had major non spinal surgery looking at whether cell-salvage reduced allogenic transfusions and where cell salvage was used it was matched to procedure, diagnosis and age with cases where it was not used over the same time period.Aim

The aim of our study was to assess the ability of orthopaedic surgical trainees to adequately assess ankle radiographs following operative fixation of unstable ankle fracture. We identified 26 Supination-External rotation (SER) stage IV fractures, and 4 Pronation-External rotation (PER) stage III fractures treated surgically in our institution. Radiographs were evaluated for shortening of the fibula, widening of the joint space, malrotation of the fibula and widening of the medial clear space. Trainees were shown these radiographs and asked to comment on the adequacy of reduction. They were then given a simple tutorial on assessing adequacy of reduction and asked to reassess these radiographs. The parameters discussed included assessment of medial clear space, drawing of the tibiofibular line, use of the “circle sign” and measurement of the talocrural angle. There was a statistically significant improvement from 64% to 71.4% (P< 0.05) in the radiographs correctly assessed by orthopaedic trainees following a short tutorial on radiographical assessment.Background
Methods and results
The avulsion fracture of the V-th metatarsal and Jones fractures often show delayed and non-union. The tension belt osteosynthesis shows often soft tissue problems due to the thin soft tisshe covering. A new minimal invasive method with the 3,5mm XXS nail and the clinical results are presented. Percutaneously the fracture is reduced with a K-wire as a joy stick. This or if the direction needed is different a second K-wire as guide is introduced and with a canulated 3,5 mm drill the place for the nail is prepared. Proximal and distal to the fracture one threaded wire locking and fracture compression through the nail (proximal longitudinal holes) are performed. 77 patients with a XXS nail fixation of MT V fractures were treated from July 1999 to Jan.2006. Clinical and radiological re-examination at 1 to 6 years were performed. The AOFAS was 22 pre- and 96 postoperatively. No pseudarthrosis but in 53 patients implant removal was done in part due to local discomfort. This was strictly correlated to the length of the threaded wires to the bone surface. 95% reached pretrauma activity levels. Satisfaction was 9 from 10 points. The XXS nails allow a percutaneous stable fixation of the avulsion and Jones fractures of the V-th metatarsus. The complication rate is low.
There is much research on metal on metal hip resurfacing arthroplasty (HRA) but few studies have reported the outcome with respect to implant characteristics from non-specialist centres. To report the survival, clinical and radiological outcomes of a single surgeon series of HRA with an average follow-up of 5 years.Background
Aim
Primary dislocation of the patella is a common acute knee disorder in children, adolescents and young adults. While primary dislocation of the patella has traditionally been treated non-operatively, primary operative repair of the medial patella-stabilizing soft tissues has been popularized more recently and thought to reduce the risk of dislocation. However, several studies have shown substantial rates of redislocation with longer follow-up time, irrespective of treatment. The purpose of this systematic review was to compare operative and non-operative treatment for primary dislocation of the patella, regarding redislocation rates and symptoms. Based on a systematic literature search of the medical literature from 1950 to 2010, three randomized and two quasi-randomized controlled clinical trials comparing surgical stabilization with non-operative treatment for patients with primary patellar dislocation were selected. The Risk of Bias Tool (Cochrane Handbook, 2008) was used to assess the quality of the studies included. Study results were pooled using the fixed-effects and random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively. Heterogeneity across studies was assessed with Q test and I-square statistic. A sensitivity analysis was performed by assessing the change on effect size by eliminating each single trial.Background
Methods
Treatment of acute Achilles tendon rupture is based on obtaining and maintaining apposition of the ruptured tendon ends. Surgical treatment utilises direct suture repair to produce this objective, while conservative or non-surgical management achieves the same effect of closing the tendon gap by immobilisation of the ankle joint in a plantar flexed position within a plaster cast or POP. There is still variability in the conservative treatment practices and protocols of acute Achilles tendon ruptures. The purpose of this study is to examine the current practice trends in the treatment of Achilles tendon ruptures amongst orthopaedic surgeons in the UK. A postal questionnaire was sent to 221 orthopaedic consultants in 25 NHS hospitals in the Greater London area in June 2010. Type and duration of immobilisation were considered along with the specifics of the regime used. Ninety questionnaires were returned giving a 41% response rate. Conservative treatment methods were used by 72% of respondents. A below knee plaster was the top choice of immobilisation (83%) within this group. The mean period of immobilisation was 9.2 weeks (Range 4-36). Weight bearing was allowed at a mean of 5.3 weeks (range 0-12) The specific regime used by consultants was quite heterogeneous across the group, however the most used immobilisation regimen was a below knee plaster in equinus with 3 weekly serial plaster changes to a neutral position, for a total of nine weeks. A heel raise after plaster removal was favoured by 73% of respondents used for a mean period of 6.4 weeks (Range 2-36). In response to ultrasound use as a diagnostic tool, 42.4% of respondents would never use it, 7.6% would use it routinely, while 50% would use it only according to the clinical situation. Comparison of foot and ankle specialists with non-specialists did not reveal a significant difference in practice in duration of immobilisation or time to bearing weight. Conservative management remains a widely practice option in the treatment of Achilles tendon ruptures. Although there are available a number of modern walking aids, the concept of functional brace immobilisation is not as widely used as below knee plaster cast immobilisation, which remains a popular choice amongst orthopaedic surgeons today. There is still no consensus on the ideal immobilisation regimen although a below knee plaster in equinus with serial changes for a total of nine weeks is the most frequently used choice. Further randomised controlled trials are required to establish the optimal treatment strategy for conservative management of Achilles tendon rupture.
Little is known about the priorities of patients undergoing surgery for idiopathic scoliosis. This study explores the priorities of adolescents and contrasts them from their parents and their surgeons. Fifty-five pairs of children and parents underwent structured interviews separately, to explore their concerns, desires and expectations both about scoliosis and surgery. Surgeons of these patients and from across Canada completed a similar questionnaire. We found a significant mismatch between child, parent and surgeon priorities. This mismatch has implications on matters relating to decision making, informed consent, understanding of patient satisfaction, and measuring outcomes that are meaningful to patients. To define the concerns, desires (goals) and expectations of adolescents undergoing surgery for idiopathic scoliosis and to contrast them from their parents and surgeons. We conducted structured interviews of fifty-five pairs of adolescents and parents separately. The questionnaire had sections on concerns, desires and expectations regarding both scoliosis and surgery, with items pertaining to present and future effects on appearance, pain, physical and psychosocial function and health. Parents also reported what their child’s responses might be. Their surgeons (four) and paediatric spine surgeons (twenty-four) across Canada completed the same questionnaire. Analysis involved repeated measures ANOVA, intra-class correlation coefficients and kappa statistics. Parents were more concerned than their children about present and future consequences of scoliosis. Surgeons were least concerned. Children, parents and surgeons agreed that improving physical appearance was the primary goal of surgery. Surgeons agreed very little about the natural history of scoliosis, other goals of surgery and the likelihood of specific outcomes. Parents wanted more from surgery than their children. Parents and patients had greater expectations of surgery than surgeons. Adolescents had different priorities from their parents, but parents were aware of this difference and knew what their child’s priorities were. Adolescents with idiopathic scoliosis, their parents and surgeons have different priorities. This mismatch might stem from uncertainty about the natural history of idiopathic scoliosis for Knowledge of patient priorities is vital for shared decision making, informed consent, understanding patient satisfaction, and for measuring outcomes that matter most to patients.

The purpose of this study is to compare the efficacy of home based vs. inpatient rehabilitation following total joint arthroplasty (TJA). Primary outcome was the self-reported WOMAC pain and function score that was used to evaluate a stratified random sample of two hundred and thirty-two patients. Despite concerns about early hospital discharge there was no difference in functional outcomes at the primary endpoint (twelve weeks post TJA) between the group receiving home based vs. inpatient rehab. Given that home- based rehab is less expensive; we would recommend the use of home based rehab protocols following elective primary TJA. Home- based rehab is increasingly utilized to save costs but concerns have been raised about early hospital discharge and adverse clinical outcomes. The aim of this RCT was to compare the efficacy of home based vs. inpatient rehab following Total Joint Arthroplasty (TJA). Despite concerns about early hospital discharge there was no difference in functional outcomes twelve weeks post TJA between the group receiving home based vs. inpatient rehab. With no significant difference in functional outcomes, less expensive home based rehabilitation protocols are recommended following elective total joint arthroplasty. We randomized two hundred and thirty-two patients to either home based or inpatient rehab following TJA using block randomization techniques. All patients at a tertiary referral centre and large volume community hospital undergoing primary elective total hip or knee arthroplasty for osteoarthritis or inflammatory arthritis were eligible. Standardized care pathways were followed for both procedures. All patients were evaluated at baseline (two weeks prior to surgery) and twelve weeks post surgery using standardized questionnaires including history, physical exam, demographics and WOMAC pain and function (the primary endpoint). In total one hundred and fifteen received a total hip and one hundred and seventeen a total knee arthroplasty; there were eighty-five men and one hundred and forty-seven women with a mean age of sixty-seven (range thirty-eight to eighty-nine) years. The groups were similar at baseline for patient demographics and WOMAC scores. At follow-up (twelve weeks post TJA) there was no statistically significant difference in WOMAC scores.
Home- based rehab is increasingly utilized to save costs but concerns have been raised about early hospital discharge and adverse clinical outcomes. This study compares the efficacy and patient satisfaction of home- based verses inpatient rehabilitation following total joint arthroplasty (TJA). Despite concerns about early hospital discharge there was no difference in functional outcomes and in patient satisfaction with procedure at the primary endpoints, between the groups receiving home based verses inpatient rehabilitation. This study compares the efficacy and patient satisfaction of home- based verses inpatient rehabilitation following total joint arthroplasty (TJA). Given that home- based rehab is less expensive, we would recommend the use of home based rehab protocols following elective primary TJA. Home- based rehab is increasingly utilized to save costs but concerns have been raised about early hospital discharge and adverse clinical outcomes. The groups were similar at baseline for patient demographics and WOMAC scores. At the six weeks, twelve weeks and one- year follow-up post TJA there was no statistically significant difference in WOMAC pain, physical function, stiffness and overall WOMAC scores. Both groups showed a trend of decrease in pain, stiffness, restriction in physical function over the follow-up period. Similarly, patient satisfaction scores at six, twelve weeks and one year did not show a statistically significant difference between the home versus inpatient group (P>
0.05) Two hundred and thirty-four patients were randomized to either home based or inpatient rehabilitation following TJA, using block randomization techniques. Standardized care pathways were followed for both procedures. All patients were evaluated at baseline (two weeks prior to surgery), six weeks, twelve weeks and one- year post surgery using standardized questionnaires. Primary outcomes were the self-reported WOMAC pain and function score and satisfaction in terms of improvement in pain and function. Despite concerns about early hospital discharge there was no difference in functional outcomes and in patient satisfaction with procedure at the primary endpoints, between the groups receiving home based verses inpatient rehabilitation.
The purpose of this study was to determine which activities are important to patients and to determine the severity of those problems. The five most important activities were walking outside, driving, walking indoors, stair climbing and daytime pain. Importance of these did not change postoperatively. The five most severe problems causing limitation were a limp, stiffness, loss of energy, daytime pain and locking. All these activities become statistically less severe over twenty-four months. Activities that are important to patients are different than the problems that are ranked by severity. Surgeons can educate patients that the severity of problems do improve over time following TKA. The objectives of this study were:
to determine the five most important activities and five most severe problems for patients prior to total knee arthroplasty (TKA) using the Patient Specific Index (PASI) and to determine the pattern of change in these activities over twenty-four months following TKA. Activities that are most important to patients are different than problems that patients find severe. Important activities remain important over time. Severe problems become less severe over time. Functional activities and PASI scores improve after TKA. Surgeons can educate patients that the problems they find most severe preoperatively do improve over time following TKA. Important activities remain important. Patients scheduled for elective primary (or revision) TKA at two tertiary care teaching hospitals were enrolled in the study, excluding those not fluent in English and those undergoing TKA for a tumour, acute fracture, or an infection of the prosthesis. Patients completed the PASI pre-operatively, six, twelve and twenty-four months post-operatively. One hundred and nineteen subjects were enrolled, nineteen were excluded. The five most important activities (ten- point scale, ten is most important) preoperatively were (mean; 95% CI): walking outside (6.25; 6.23–6.27), driving (6.17; 6.12–6.22), walking indoors (6.14; 6.12–6.16), climbing stairs (6.12; 6.10–6.14), and daytime pain (5.84; 5.81–5.87). These activities were not statistically less important over time. The most severe problems were limping (4.81; 4.77–4.85), stiffness (4.59; 4.56–4.62), lack of energy (4.51; 4.47–4.55), daytime pain (4.46; 4.43–3.39) and locking (4.38; 4.27–4.49). These were significantly less severe at twenty-four months (p <
.001).
Five surgeons independently rated clinical photographs of forty patients with AIS. Ratings of shoulder blades, shoulder symmetry, and waist symmetry were related to “overall appearance”, and were also correlated with rib prominence and Cobb angle. Because the components of surgeons’ ratings of appearance differed, this may lead to inconsistent recommendations regarding surgery. To identify patient characteristics associated with surgeons’ ratings of patient physical deformity in Adolescent Idiopathic Scoliosis (AIS). Five surgeons independently rated clinical photographs of forty patients with AIS. Surgeons separately rated the appearance of patients’ shoulder blades, shoulder symmetry, waist symmetry and also rated their “overall appearance Surgeons’ mean rating for “overall appearance” was moderately correlated with rib prominence (r = 0.48), vertebral rotation (r = 0.44) and Cobb angle (r = 0.53). Surgeons’ rating of patients’ “overall appearance” was affected by each of: shoulder blades (p = 0.001), shoulder symmetry (p = 0.01) and waist symmetry (p = 0.001). However, each surgeon weighted components of patients’ appearance differently to arrive at their overall rating of appearance (p<
0.006). Because patients’ physical appearance is an important element of surgical decision making, differences among surgeons could be contributing to inconsistent recommendations. Surgeons’ ratings of physical appearance are based on surgeons’ ratings of patients’ shoulder blades, waist symmetry and shoulder symmetry but surgeons weight those elements differently. Surgeon decision making is complicated. It is based on radiographs and subjective assessment. Patients’ appearance undoubtedly influences surgeon recommendation for surgery. We need to clarify surgeons’ ratings and improve the criteria for surgeon decision making.
This study compared the effect of manipulation with a period of normal activity on the range of intervertebral sidebending. Thirty asymptomatic male volunteers were randomised to treatment or control groups. All were subjected to low-dose X-ray screening through 80° of passive lumbar spine side-bending. Motion sequences were digitised at a 5Hz sampling rate. The treatment group (n=16) had rotary manipulation to each lumbar linkage, followed by normal activity. The control group (n=14) had normal activity only. Both groups were then re-screened. Each vertebral pair was tracked and intervertebral rotation throughout the motion measured. Three subjects were analysed 10 times for reliability and all intervertebral motion was tracked twice. Twenty-one manipulated linkages and 10 controls met the reliability criteria. For non-manipulated segments the mean range at first screening was 14.2° (SD 1.39) and manipulated segments 12.8° (SD 3.81). The range of the non-manipulated segments increased by +0.9o and the manipulated segments by +0.4°. The change in manipulated segments was negligible and similar to controls, although the instrument can be sufficiently reliable to measure a 2° difference. The technique is sufficiently robust to determine if spinal manipulation changes these ranges in selected patients.
We aimed to assess individual differences in complaints in patients just before total hip replacement (THR) and the importance attached to the relief of each of them. In a pilot study, using open-ended interviews, we identified 16 main complaints, four of which (night pain, unequal leg length and discomfort during sexual and recreational activities) were not included in any of the six hip-rating scales in general use. Each of the 16 complaints was then assessed in 72 patients and rated for severity and the relative importance of relief. From this we calculated a severity-importance rating for each complaint and a patient-specific score for all complaints. The 72 patients had a mean age of 64 years (17 to 92) and 51% were men. The most important reasons for wanting a THR were day pain and walking difficulty, but the complaints mentioned above and not included in standard hip scores were also important. Greater attention to the individual requirements of patients might improve evaluation of the outcome of orthopaedic treatments.
Long radiographs are used to measure lower limb axial alignment, to assess the progression of deformity, and to plan corrective surgery. The purpose of this study was to test the belief that jigs are necessary in order to control limb position for radiography. Above-knee amputated limbs were fixed in different positions of rotation and of knee flexion and radiographed to study the effect on the apparent alignment of the limb. If the limb was rotated no more than 10 degrees from the neutral the effect on apparent axial alignment was minimal and radiographic measurement was reliable. This suggests that standardised positioning jigs are not needed in routine clinical practice.
This is a preliminary report of the results of knee joint replacements using the Liverpool Mark II knee joint system which consists of a bicondylar prosthesis and a set of stereotactic instruments. The prosthesis has been developed from Gunston's concept, and the special instruments ensure its accurate insertion through meniscectomy-type incisions placed on either side of the patella. Particular features of the prosthesis are near-normal articulation, and the simplicity of the operation. Sixty-two knee replacements were implanted in forty-two patients between the spring of 1974 and January 1977. After the operation fifty-six knees were painless and four others produced only slight pain. Full extension was obtained in fifty-eight knees, and none showed a valgus or varus deformity. Collateral laxity was absent in all knees. There were two failures. These early results are most encouraging.
