Introduction

Severe, multiplanar, fixed, pantalar deformities present a challenge to orthopaedic surgeons. Surgical options include limb salvage or amputation. This study compares outcomes of patients with such deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA).

Methods

Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17 to 72 years) and median follow-up duration was 49.9 months (18.0 to 253.7 months). Patients with chronic regional pain syndrome, tumour, acute trauma or diabetic Charcot arthropathy were excluded. Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgical outcome and whether they would have the same surgery again.

Introduction

Pes cavovarus is a foot deformity that can be idiopathic (I-PC) or acquired secondary to other pathology. Charcot-Marie-Tooth disease (CMT) is the most common adult cause for acquired pes cavovarus deformity (CMT-PC). The foot morphology of these distinct patient groups has not been previously investigated. The aim of this study was to assess if morphological differences exist between CMT-PC, I-PC and normal feet (controls) using weightbearing computed tomography (WBCT).

Methods

A retrospective analysis of WBCT scans performed between May 2013 and June 2017 was undertaken. WBCT scans from 17 CMT-PC, 17 I-PC and 17 healthy normally-aligned control feet (age-, side-, sex- and body mass index-matched) identified from a prospectively collected database, were analysed. Eight 2-dimensional (2D) and three 3-dimensional (3D) measurements were undertaken for each foot and mean values in the three groups were compared using one-way ANOVA with the Bonferroni correction.

Abstract

Background

Multiple devices can stabilise the MTP joint for arthrodesis. The ideal implant should be easy to use, provide reproducible and high quality results, and ideally enable early rehabilitation to enable faster return to function, whilst lessening soft tissue irritation. We prospectively evaluated the combination of the IO-Fix (Extremity Medical, NJ, USA) device which consists of an intra-osseous post and lag screw that offers these features with full bearing of weight after surgery.

Methods

67 feet in 65 patients were treated over 31 months. After excluding patients lost to follow-up, undergoing revision arthrodesis, or concomitant first ray procedures, there were 54 feet in 52 patients available with a minimum 12 month follow-up with clinical and radiographic outcomes. All patients were treated using a similar operative technique with immediate bearing of weight in a rigid soled shoe.

Background

Partial facetectomies with pedicle screw instrumentation is widespread and a well described technique for achieving posterior correction of scoliosis. Newton et al. first described the use of the UBS in the posterior correction of AIS in 2014. The aim of this study was to compare the effectiveness of the UBSPO in achieving posterior correction in Type1 AIS as compared to the traditional partial facetectomies. Aim of this study was to assess the effectiveness of USBPO in achieving posterior correction in Type 1 AIS as compared to partial facetectomies.

Methods

A retrospective review of 40 patients with type 1 AIS who had undergone a posterior correction of scoliosis between 2010 and 2016 was performed. Group A (n=20) consisted of consecutive patients that had partial facetectomies while Group B (n=20) consisted of consecutive patients having UBSPO. Both groups were matched for demographic parameters. Pre and post-operative radiographic parameters and operative data in both groups were compared. The Mann-Whitney U test was used for statistical analysis.

Acute Achilles tendon (AT) rupture management remains debatable but non-operative functional regimes are beginning to dominate current treatment algorithms. The aim of this study was to identify predictors of functional outcome in patients with AT ruptures treated non-operatively with an immediate weight bearing functional regime in an orthosis.

Analysis of prospectively gathered data from a local database of all patients treated non-operativelyat our institution with anAT rupture was performed. Inclusion criteria required a completed Achilles Tendon Rupture Score (ATRS) at a minimum of 8 months post rupture. The ATRS score was correlated against age, gender, time following rupture, duration of treatment in a functional orthoses (8- and 11-week regimes) and complications. 236 patients of average age 49.5 years were included.

The mean ATRS on completion of rehabilitation was 74 points. The mean ATRS was significantly lower in the 37 females as compared to the 199 males, 65.8 vs 75.6 (p = 0.013). Age inversely affected ATRS with a Pearsons correlation of −0.2. There was no significant difference in the ATRS score when comparing the two different treatment regime durations. There were 12 episodes of VTE and 4 episodes of re-rupture. The ATRS does not change significantly after 8 months of rupture.

Patients with AT ruptures treated non-operatively with a functional rehabilitation regime demonstrate good function with low re-rupture rates. Increasing age and female gender demonstrate inferior functional outcomes.

Introduction

Outcomes following large joint arthroplasty are influenced by the accuracy of implant placement. Patient specific (PS) technology has been used in knee arthroplasty surgery however, its application in total hip arthroplasty remains relatively unexplored.

Aims

We investigated whether conventional or PS guides, resulted in a more accurate reconstruction of the pre-operative head centre position.

Background and Purpose

Chronic low back pain (CLBP) can be constant or episodic. Fluctuations are common. We present two different pictures of the CLBP experience; timelines illustrating back pain over time and ‘web diagrams’ showing a snapshot of a phase in time.

Methods

Semi structured interviews from 34 participants from the UK BeST trial included timelines drawn collaboratively by the researcher and participant. Symptoms, events, treatment and consultations were arranged chronologically along a timeline. Initial thematic analysis on 63 interviews gave bio-psychosocial themes that were spoken about in an integrated way. Further analysis explored these interactions between themes. Interactions were classified as; helpful to recovery, unhelpful or mixed. Web diagrams were drawn for each interview and classified as Dense- mostly unhelpful interactions, Open – a combination of helpful and unhelpful interactions and Sparse – mostly helpful interactions.

Background

The available treatments for NSLBP (Non-Specific Low Back Pain) provide, typically, small to moderate average benefits to patients. The aim of this pilot cluster RCT was to test the hypothesis that the use of a patient decision aid together with an informed shared decision making consultation would produce better outcomes in satisfaction with treatment at four month follow-up.

Methods

We developed a DSP (Decision Support Package). We randomised the physiotherapists and trained those in the intervention arm in informed shared decision making and communication. Participants were recruited from a local physiotherapy department and those allocated to an appointment with an intervention therapist were sent a copy of the DSP in the post. Participants then attended their appointment as usual.

Introduction

Yellow flags are psychosocial indicators which are associated with a greater likelihood of progression to persistent pain and disability and are referred to as obstacles to recovery. It is not known how effective clinicians are in detecting them. Our objective was to determine if clinicians were able to detect them in secondary care.

Methods

111 new referrals in a specialist spine clinic completed the Oswestry Disability Index (ODI) and a range of other validated questionnaires including the yellow flag questionnaire adapted from the psychosocial flags framework. Clinicians blinded to the patient data completed a standardized form to determine which and how many yellow flags they had identified.

Background

We have developed a LBP (low back pain) repository with IPD (individual patient data) from therapist-delivered intervention RCT's from various institutions, nationally and internationally (19 trials, 9328 patients). We will perform IPD meta-analyses to identify and determine the most effective and cost-effective treatments for subgroups of patients. Disability due to LBP is a key outcome of interest. However, there was no common disability measurement that was used in all the RCT's. We report here our assessment as to whether different disability measures are sufficiently comparable to allow pooling across trials.

Method

We used data from seven trials (n = 5015 patients) that had at least two of the following measurements: RMDQ (Roland Morris Disability Questionnaire), MVK (Modified Von Korff disability score), physical component scale of SF-12/36, Patient Specific Functional Scale, and Hannover Functional Ability Questionnaire. Within each trial, the change score between baseline and short-term follow-up was computed. These change scores were then converted from one outcome measure to another with linear regression and ridge-reroughed linear models. They were also tested for correlation and responsiveness (the ability to detect changes in condition, measured by standardised response means).

Introduction

In Total Hip Arthroplasty (THA), polyethylene wear reduction is key to implant longevity. Oxidized Zirconium (OxZi) unites properties of a ceramic bearing surface and metal head, producing less wear in comparison to standard Cobalt-Chromium (CoCr) when articulating with Cross-linked polyethylene (XLPE) in vitro. This study investigates in vivo polyethylene (PE) wear, outcomes and complications for these two bearing couples in patients at 5 year follow-up

Methods

400 patients undergoing THA across four institutions were prospectively randomised into three groups. Group I received a cobalt-chrome (CoCr) femoral head/ cross-linked polyethylene (XLPE) liner; Group II received an OxZi femoral head/ ultrahigh molecular weight polyethylene (UHMWPE) liner; Group III received an OxZi femoral head/XLPE liner. All bearing heads were 32 mm. Linear wear rate was calculated with Martell computer software. Functional outcome and complications were recorded.

Study purpose and background

There is growing concern that current outcome measures of back pain trials do not comprehensively capture what is important to patients. Some researchers believe we need to incorporate patients in the development of ‘next-generation’ outcomes. As a preliminary step to patient-interviews, we aimed to articulate ‘important change’ from the patients' perspective, as represented in reports of qualitative investigations inadvertently or directly exploring this.

Summary of methods used and results

We adopted a multi-strand search of electronic databases, and citation and reference tracking. Two researchers identified qualitative investigations relating to low back pain. Data were abstracted and synthesised using meta-ethnographic processes. Provisional results, based on 41 studies, indicate few studies have directly addressed this issue, but that data regarding experience and expectations may be useful. Whilst results suggest that practically, patients are concerned with (re-)engagement in meaningful activities, the more experientially focused literature suggests that patients want to be believed and have validated their experiences and identity as someone ‘doing battle’ with pain. Patients seek not only diagnoses, treatment and cure, but simultaneously reassurance of the absence of pathology. In the absence of tenable diagnoses, some feel they must not adopt a ‘sick role’. Some struggle, but manage to meet others' expectations; thereby undermining the credibility of their pain/disability claims. Others withdraw, fearful of disapprobation and unable or unwilling to accommodate social demands. Patients generally seek to regain their pre-pain healthy, and emotionally robust state.

Background

Patellar instability is a complex, multi-factorial disorder. Radiological assessment is regarded as an important part of the management of this population. The purpose of this study was to determine the intra- and inter-rater reliability of common radiological measurements used to evaluate patellar instability.

Methods

One hundred and fifty x-rays from 51 individuals were reviewed by five reviewers: two orthopaedic trainees, a radiological trainee, a consultant radiologist and an orthopaedic physiotherapist. Radiological measurements assessed included patellar shape, sulcus angle, congruence angle, lateral patellofemoral angle (LPA), lateral patellar displacement (LPD), lateral displacement measurement (LDM), boss height, and patellar height ratios (Caton-Deschamps, Blackburne-Peel, Insall-Salvati). All assessors were provided with a summary document outlining the method of assessing each measurement. Bland-Altman analyses were adopted to assess intra- and inter-rater reliability.

Aims

To develop a decision aid - Decision Support Package (DSP) - that will provide low back pain (LBP) patients, and their treating physiotherapists with information on the treatment options available to the patients

To develop a training package for physiotherapists on how to use the DSP

To encourage and evaluate the informed shared decision making (ISDM) process between patients and physiotherapists during consultation.

Method

We developed a DSP informed by existing research and collaboration with physiotherapists, patients and experts in the field of decision aids and LBP. We did six pieces of exploratory work: literature review; 2009 NICE LBP guidelines review; qualitative screening of transcripts of interviews of LBP patients; focus groups (patients); nominal group (physiotherapists), and Delphi study (experts). We collated these data to develop the DSP. We also developed a training package for physiotherapists.

AIM

Failure of a primary anterior cruciate ligament (ACL) reconstruction is associated with poor functional outcomes even after revision surgery. The aim of this study is to identify early predictors for failure, so that it may aid in recognition of at-risk patients.

METHOD

An observational study was conducted of 623 patients undergoing primary ACL reconstruction by a single surgeon over a 72 month period. Patient and procedure related parameters including age, gender, BMI, time to surgery, graft size, fixation methods, meniscal and chondral injuries, meniscal surgery, radiological parameters and post-operative IKDC scores. Logistic regression modeling was employed to identify those factors which were statistically significant for failure.

Aim

To evaluate the results and complications of bone transport in the treatment of massive tibial bone defects, using the Ilizarov method.

Methods

15 patients underwent bone transport using the Ilizarov technique to treat massive tibial bone defects. The average age of the patients was 8.7 years (3–24 years) and the mean bone defect was 10.8 cms. Following a latent period of 1 week, distraction of the transport doughnut was commenced at 1mm/24 hours in 4 quarterly turns. A docking procedure was performed in 7 cases which involved freshening of the bone ends and autogenous bone grafting from the iliac crest. Following docking the fixator was removed once the regenerate had consolidated.

Introduction

Unicondylar knee replacements (UKR) may be more effective compared to Total knee replacements (TKR) in unicompartmental arthritis. We report patient outcomes & satisfaction data in an age matched cohort of patients with either a UKR or TKR.

Method

A single unit and single surgeon series of patients were recruited. Data was retrospectively collated for 68 patients with more than 24 months follow-up. UKR was undertaken in patients with isolated medial compartment osteoarthritis; stable ACL and less than grade 3 lateral patellar changes of the Outerbridge classification. TKR was undertaken for the rest. The patients were assessed with validated knee scores including the Total Knee Function Questionnaire (TKFQ) which focuses on recreational & sporting outcomes as well as activities of daily living (ADL). Patient satisfaction and perception of knee normality was measured on a visual analogue scale.

Purpose: Pinch strength has been shown to be a predictor of the ability to grip objects and perform functional hand-related tasks. As the sole flexor of the thumb IP joint, the flexor pollicus longus (FPL) muscle has previously been shown to play an essential role in directing thumb tip force as well as contribute to overall pinch strength. The relative contribution of FPL to pinch strength is unknown however. As the FPL may be affected in several acute and chronic conditions, determining the contribution of FPL to pinch strength may be useful in planning as well as evaluating treatment options. The purpose of this study was to estimate the contribution of FPL to pinch strength in-vivo using an EMG-guided, selective motor blockade, test-retest protocol.

Method: 11 healthy volunteers were recruited to participate in the study. All participants completed a brief questionnaire regarding prior hand injuries and subsequently underwent a physical examination to assess baseline hand function. Baseline pinch strength was recorded using three different pinch techniques: key pinch, 3-point chuck grasp, and tip pinch. Participants then underwent EMG-guided lidocaine blockade of the FPL muscle. Motor evoked potentials as well as skin potentials were used to confirm adequate FPL blockade. The physical exam was repeated as were pinch strength measurements. Post block splinting was necessary to stabilize the thumb IP joint. Grip strength, in addition to clinical examination, was utilized pre and post block to assess for inadvertent blockade of other muscle groups or nerves. A final clinical evaluation was conducted at study completion to note any complications or adverse effects.

Results: All three types of pinch strength showed a significant difference between pre and post measurements (p< 0.01). The mean differences pre and post were 9.7N,6.4N, and 5.2N in key, 3-point chuck, and tip pinch respectively (p< 0.01). The relative contribution of FPL for each pinch type was 53.2%,39.5%, and 44.3%. EMG, motor evoked potentials, and skin potentials confirmed adequate paralysis of the FPL. Physical examination did reveal decreased sensation in median and radial nerve distributions in some individuals, however the effect on observed motor function was negligible. Grip strength decreased by only 4N post blockade confirming no clinically significant median nerve motor blockade. The protocol was well tolerated and no serious complications were noted.

Conclusion: Using an in-vivo model we were able to estimate the contribution of FPL to overall pinch strength. In our study, FPL’s contribution to pinch strength was estimated to be 9.7N,6.4N, and 5.2N in key, 3-point chuck, and tip pinch respectively (p< 0.01). The relative contribution of FPL for each pinch type was 53.2%, 39.5%, and 44.3%. Inherent limitations in study design may have tended to overestimate the contribution of FPL to pinch. This information may be useful in planning and evaluating treatments for acute and chronic conditions affecting FPL function.

Introduction: Blood transfusion is not uncommon in patients following joint replacement surgery. However, allogeneic transfusion is associated with potential risks ranging from immune mediated allergic reactions to transmission of blood-borne organisms. Furthermore its use has a significant economical impact on healthcare services.

Methods: A retrospective audit of the case notes and haematological records of 196 patients who underwent primary total hip (THR), resurfacing hip (BHR) or total knee replacement (TKR) was carried out. Patients were routinely cross-matched for 2 units of blood if their pre-operative haemoglobin (Hb) levels were < 12g/dL in our cohort. Patient details including age, sex, BMI, comorbidities, and ASA grade were also collected. Surgical parameters such as operation time, tourniquet time (for TKR procedures) and trigger haemoglobin levels (Hb) with timing of transfusion were noted. Statistical analysis was undertaken to identify risk factors for transfusion.

Results: Forty-seven (24%) patients were transfused in our cohort. 78.7% of these patients were appropriately transfused with a trigger Hb of < 8g/dL. Patients transfused with a trigger Hb of > 8g/dL were no different with respect to demographics, procedure type and comorbidities. The average postoperative time interval to transfusion was 2.1 days. Five patients required an intra-operative transfusion. The mean pre-operative Hb levels in transfused and non transfused patients were 12.4 g/dL and 13.5 g/dL respectively. The mean number of units transfused was 2.31. A total of 109 units of blood were used: of these 70 units were cross-matched pre-operatively.

Univariate analysis established a significant relationship between the need for postoperative transfusion and preoperative Hb levels (p< 0.0001), length of surgery (p=0.01), age (p=0.03), history of respiratory disease (p=0.028) and hypertension (p=0.01). There was no significant relationship with respect to ASA grade and procedure type. Multivariate logistic regression analysis revealed pre-operative Hb (p< 0.0001) and age (p=0.015) as the strongest predictors of the need for post-operative transfusion. There is a strong correlation between length of surgery and time interval to transfusion (p=0.037).

Conclusion: Utilisation rates of blood products after primary hip and knee arthroplasty procedures exceed that of what is available from pre-operative cross-matching. In our institution more than 20% of patients may have been transfused inappropriately based upon local guidelines. The decision to cross-match blood pre-operatively for elective arthroplasty procedures should be re-evaluated in light of both patient age and pre-operative Hb levels. Postoperative monitoring of Hb levels should be undertaken early in patients with a prolonged duration of surgery.

Introduction: Rupture of the anterior cruciate ligament (ACL) is a serious injury associated with symptomatic instability of the knee. There is an increasing trend for confirmation of diagnosis with magnetic resonance imaging (MRI) before proceeding to reconstruction. The overall sensitivity and specificity of diagnosis using this modality is more than 95%. It is however observer-dependent. We have developed a simple 4 point recognition card to increase the pick-up rate of this injury for professionals without specific radiological training such as orthopaedic trainees. The aim of this study was to determine how much improvement could be achieved using this card and whether any change was sustained.

Methods: 20 participants (orthopaedic trainees surgeons and medical students) were shown 20 MRI scans of the knee (10 with complete ACL ruptures and 10 with normal ACLs) and asked which scans were demonstrative of ACL pathology. Each participant was then randomly allocated to either having verbal teaching in the standard fashion about detection of ACL injuries [Group 1] or given written cards detailing a 4 point recognition plan for recognising ACL injuries on MRI [Group 2]. A repeat test of MRI scans was performed on each participant immediately after the teaching session and at 3 weeks.

Results: The mean time taken to teach Group A was 14 mins and Group B was 11 mins (p < 0.05). The mean number of correct diagnoses was 2.7/10 in Group A and 3.1/10 in Group B pre-intervention (p > 0.05). Immediately following intervention, there were 6.1 correct diagnoses in Group A and 8.2 in Group B (p < 0.05). At 3 weeks, there were 3.4 correct diagnoses in Group A and 7.9 in Group B (p < 0.05). The difference in number of correct diagnoses at 3 weeks compared to immediately following intervention was significant in Group A (p < 0.05), but not in Group B (p > 0.05).

Conclusions: The results support the use of the 4 point recognition card as to tool for increasing the pick-up of ACL injuries on MRI. It offers advantages over standard teaching Methods: since it takes less time to teach and the necessary information is retained to a greater degree than with traditional teaching methods.
