Children with spinal dysraphism can develop various musculoskeletal deformities, necessitating a range of orthopaedic interventions, causing significant morbidity, and making considerable demands on resources. This systematic review aimed to identify what outcome measures have been reported in the literature for children with spinal dysraphism who undergo orthopaedic interventions involving the lower limbs. A PROSPERO-registered systematic literature review was performed following PRISMA guidelines. All relevant studies published until January 2023 were identified. Individual outcomes and outcome measurement tools were extracted verbatim. The measurement tools were assessed for reliability and validity, and all outcomes were grouped according to the Outcome Measures Recommended for use in Randomized Clinical Trials (OMERACT) filters.Aims

The number of females within the speciality of trauma and orthopaedics (T&O) is increasing. The aim of this study was to identify: 1) current attitudes and behaviours of UK female T&O surgeons towards pregnancy; 2) any barriers faced towards pregnancy with a career in T&O surgery; and 3) areas for improvement. This is a cross-sectional study using an anonymous 13-section web-based survey distributed to female-identifying T&O trainees, speciality and associate specialist surgeons (SASs) and locally employed doctors (LEDs), fellows, and consultants in the UK. Demographic data was collected as well as closed and open questions with adaptive answering relating to attitudes towards childbearing and experiences of fertility and complications associated with pregnancy. A descriptive data analysis was carried out.Aims
Methods
Global literature suggests that female surgical trainees have lower rates of independent operating (operative autonomy) than their male counterparts. The objective of this study was to identify any association between gender and lead/independent operating in speciality orthopaedic trainees within the UK national training programme. This was a retrospective case-control study using electronic surgical logbook data from 2009 to 2021 for 274 UK orthopaedic trainees. Total operative numbers and level of supervision were compared between male and female trainees, with correction for less than full-time training (LTFT), prior experience, and time out during training (OOP). The primary outcome was the percentage of cases undertaken as lead surgeon (supervised and unsupervised) by UK orthopaedic trainees by gender.Aims
Methods
Legg-Calvé-Perthes disease (LCPD) often results in femoral head deformity and leg length discrepancy (LLD). Objective of this study was to analyse femoral morphology in LCPD patients at skeletal maturity to assess where the LLD originates, and evaluate the effect of contralateral epiphysiodesis for length equalisation on proximal and subtrochanteric femoral lengths. All patients treated for LCPD in our institution between January 2013 and June 2020 were retrospectively reviewed. Patients with unilateral LCPD, LLD of ≥5mm and long leg standing radiographs at skeletal maturity were included. Total leg length, femoral and tibial length, articulotrochanteric distance (ATD) and subtrochanteric femoral length were compared between LCPD side and unaffected side. Furthermore, we compared leg length measurements between patients who did and who did not have a contralateral epiphysiodesis.Introduction
Materials and Methods
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
Materials and Methods
This study compares outcomes in patients with complete congenital fibula absence, associated with severe lower limb deformity, treated with an amputation protocol to those using an extension prosthesis. 32 patients were identified. 9 patients (2M: 7F, median age at presentation of 22 yrs) utilized an extension prosthesis. 23 patients (16M: 7F, median age at presentation of 10 months) underwent 25 amputations during childhood: only two underwent tibial kyphus correction to facilitate prosthetic wear. Mobility was assessed using the SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. Patients undergoing amputation were further subdivided by age, below and above 2 yrs at the time of surgery.Purpose
Method
This study compares outcomes in patients with complete congenital fibula absence treated with an amputation protocol to those using an extension prosthesis. Complete fibula absence presents with significant lower limb deformity. Parental counselling regarding management is paramount in achieving the optimum functional outcome. Amputation offers a single surgical event with minimal complications and potential excellent functional outcome.Purpose
Introduction
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.
Although DDH is one of the most common skeletal dysplasias (incidence 1.5 cases per 1000 births), it remains slow and costly to recruit large-scale patient cohorts for powerful genetic association studies. In this work we have successfully used the NJR as a platform to generate a DDH biobank of 907 individuals, upon which we have conducted the first ever genome-wide association study (GWAS) for DDH. 5411 patients recorded as having a hip replacement for ‘hip dysplasia’ between March 2003 and December 2013 were approached to participate in the study. Following filtering by questionnaire for non-DDH cases and non-European Caucasians, 907 patients returned a completed saliva sample. A randomly selected sample of individuals participating on the UK Household Longitudinal Study that had been previously genotyped using the same platform were used as controls at a case:control ratio of 1:4. A further data set consisting of 332 cases, 1375 controls and 26 variants was used to replicate the top signals.Introduction
Methods
This study aimed to define the rates of lower limb angular correction using temporary hemiepiphysiodesis in differing skeletal pathologies. A retrospective review of 61 children (36M:25F) with angular deformities about the knee who underwent 8-plate hemiepiphysiodesis (mean age 10.8y) was undertaken. The children were divided into 9 groups based on their underlying pathology (lower limb hypoplasia, Blount's disease, skeletal dysplasia, rickets, metabolic disease, acquired growth disturbance, vascular malformation, steroid use and complex genetic disorders). Radiographic measurements of each limb segment was undertaken using the TraumaCad® digital templating software based on standing long-leg radiographs - mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA). The rate of correction of each parameter was calculated as a function of the time lapse between the operation date and first radiographic evidence of full correction of the mechanical axis (zone 1). A total of 144 limb segments (80 distal femoral, 64 proximal tibial physes) were analysed. 62.5% of children had mechanical axes outside the knee joint at the time of operation; 63.2% achieved full correction. The rate of angular correction at the distal femur (mLDFA) was quickest in those with acquired growth disturbance (1.15°/month), complex genetic disorders (1.12°/month) and rickets (0.93°/month). It was slowest in those with vascular malformation (0.40°/month), lower extremity hypoplasia (0.44°/month) and metabolic disease (0.49°/month). At the proximal tibia, mMPTA correction was quickest in those with acquired growth disturbance (0.77°/month) and skeletal dysplasia (0.57°/month); whilst being slowest in those with metabolic disease (0.22°/month) and Blount's disease (0.29°/month). The rate of angular correction about the knee varies with the underlying pathology with correction rates varying up to 3-fold. This study demonstrated the differential rate of correction of angular deformities in children with different skeletal pathologies, which would help guide the timing of hemiepiphysiodesis.
To review the natural history of upper limb osteochondromas and assess their functional effect. We performed a retrospective casenote review of a consecutive patient cohort presenting between 1997–2012 with upper limb osteochondromas. Indications for surgical intervention were noted and considered to be cosmetic, functional (including pain relief) and ‘prophylactic’ in terms of deformity prevention. All patients were invited to complete questionnaires for the PODCI, DASH, OSS and MHS scores.Aim
Materials
To see if the addition of a locking plate to FD rod fixation of osteogenesis imperfecta confers extra strength and allows earlier mobilisation. Osteogenesis imperfecta is a heterogeneous group of disorders with congenital osseous fragility. The goal of surgery is to minimise the incidence of fracture and correct deformity. The concept of multilevel osteotomies and intramedullary fixation with a non-extendable nail was popularised by Sofield and Millar in 1959. The Bailey Dubow telescoping nail was introduced in 1963. The Fassier-Duval (FD) telescoping nail is a more recent design inserted via smaller incisions, in conjunction with percutaneous osteotomies. However there are still problems. Often the medullary canal may be too narrow to harbour a nail of adequate size for the body. Furthermore they do not give significant rotational control, which is compounded by the elasticity of the soft tissues.Purpose of Study
Introduction
Van Nes rotationplasty may be used for patients
with congenital proximal focal femoral deficiency (PFFD). The lower
limb is rotated to use the ankle and foot as a functional knee joint
within a prosthesis. A small series of cases was investigated to
determine the long-term outcome. At a mean of 21.5 years (11 to
45) after their rotationplasty, a total of 12 prosthetic patients
completed the Short-Form (SF)-36, Faces Pain Scale-Revised, Harris
hip score, Oswestry back pain score and Prosthetic Evaluation Questionnaires,
as did 12 age- and gender-matched normal control participants. A
physical examination and gait analysis, computerised dynamic posturography
(CDP), and timed ‘Up &
Go’ testing was also completed. Wilcoxon
Signed rank test was used to compare each PFFD patient with a matched
control participant with false discovery rate of 5%. There were no differences between the groups in overall health
and well-being on the SF-36. Significant differences were seen in
gait parameters in the PFFD group. Using CDP, the PFFD group had
reduced symmetry in stance, and reduced end point and maximum excursions. Patients who had undergone Van Nes rotationplasty had a high
level of function and quality of life at long-term follow-up, but
presented with significant differences in gait and posture compared
with the control group. Cite this article:
To assess the efficacy of combined medical and surgical management in obtaining normal lower limb mechanical alignment in a patient cohort with genotypically similar hypophosphataemic rickets. A notes and radiograph audit was performed of all patients attending our institution with hypophosphataemic rickets: a subset with PHEX gene anomalies was studied further. Lower limb radiographs were assessed at two points during childhood and note made of treatment start, compliance; indication, timing and result of surgery. Standing leg alignment radiographs were measured at skeletal maturity or at latest review.Aim
Methods
We hypothesised that Vitamin D deficiency could be related to SUFE in children without endocrinological abnormalities. We therefore sought to examine prevalence and severity of Vitamin D insufficiency in a cross-section of SUFE patients. Vitamin D levels were tested for at time of hospital admission for operative treatment of SUFE. Seven patients, between the months of July 2011 to November 2011, presented to our institution. All were chronic, stable slips treated with in-situ screw fixation. All patients presented in the summer months and were operated on within 3 weeks of presentation.Purpose of study
Methods
To evaluate the results and complications of bone transport in the treatment of massive tibial bone defects, using the Ilizarov method. 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.Aim
Methods
To define the orthopaedic problems associated with pseudoachondroplasia (PSACH) and their functional impact. We reviewed the medical records of 12 consecutive patients presenting to our unit. Radiographic analysis of deformity included assessment of mechanical axis and dysplasia at hip, knee and ankle measured by acetabular index (AI), Reimer's migration percentage (MP), neck-shaft angle, distal lateral femoral (aDFLA) and proximal (mMPTA) and distal tibial angles. The paediatric/adolescent PODCI questionnaires and the SF36 were used to assess quality of life issues.Purpose
Methods
To document the success rate of closed reduction and soft tissue release in the treatment of bilateral true dislocation in developmental dysplasia of the hip (DDH). Case-note review of 22 children (44 hips) with idiopathic bilateral hip dislocation referred to a tertiary centre before walking age. The management protocol was as follows:
Examination under general anaesthesia, arthrogram, closed reduction and appropriate soft tissue release (adductors/psoas), application of a ‘frog’ cast. CT scan at 2 weeks to confirm reduction. Change of cast and arthrogram at 6 weeks to confirm improving position and stability. Cast removal at 12 weeks, and application of an abduction brace for 6 weeks. Treatment failure could occur on day 1 (failure of reduction), at week 2 (failure to maintain reduction), at week 6, or after cast removal.Purpose
Methods
To determine whether radiographically demonstrated femoral neck irregularities (pistolgrip-deformity, focal prominences or lytic defects) are associated with positive clinical impingement tests. The 1989 Bergen birth cohort (n=4004) was invited to a population-based follow-up including clinical examination and two pelvic radiographs. 2081 (52%) were enrolled. Associations between clinical and radiographic findings were examined using chi-squared or Fischer's exact test.Purpose
Methods
To investigate the effect of soft tissue release (STR) and the length of postoperative immobilisation on the long term outcomes of closed reduction (CR) of the hip for developmental dysplasia of the hip. 77 hips (72 patients) who had undergone closed reduction (CR) between 1977-2005 were studied retrospectively to review their outcome (Severin grade), identify the reasons for failure and to assess factors associated with residual dysplasia. Particular attention was paid to the use of a STR at the time of CR (to improve initial hip stability) and the duration of postoperative immobilisation.Purpose
Materials
To document the incidence and nature of complications associated with hemiepiphysiodesis using a screw and plate device (8-plate, Orthofix). We reviewed case notes and radiographs of 71 children (130 segments) with lower limb deformities treated with temporary hemiepiphyseal arrest using the 8-plate. 96% of deformities were in the coronal plane, 4% sagittal. 72% of coronal deformities demonstrated valgus malalignment. We defined three types of complications: complications Complications were related to variables of patient age, gender, diagnosis, location of deformity and associated surgery.Purpose
Methods
Following the cuneiform osteotomy, patients were mobilized partial weight bearing for 8 weeks. At a mean 12 month follow up, radiographs confirmed that all oste-otomies had united and no hip showed evidence of AVN.
Patients were reviewed clinically and completed questionnaires documenting pain, function and satisfaction before and after treatment at a mean follow-up of 44 months (range 14–131). All patient’s notes and radiographs were examined.
Complications included almost universal minor pin-site infections, flexion contractures of the toes in 5 feet and skin ulceration in 2 feet, 1 requiring a muscle flap.
Scoliosis and hip subluxation/dislocation are common and often coexistent problems encountered in patients with cerebral palsy (CP). The underlying mechanism may be related to muscle imbalance. Surgical correction may become necessary in severe symptomatic cases. The effect of surgical correction of one deformity on the other is not well understood. We retrospectively reviewed a series of 17 patients with total body cerebral palsy with diagnoses of both scoliosis and hip subluxation who had undergone either surgical correction of their scoliosis (9 patients) or a hip reconstruction to correct hip deformity (8 patients). In all patients, the degree of progression of both deformities was measured, radiographically, using the Cobb angle for the spine and the percentage migration index for hip centre of rotation at intervals before and at least 18 months post surgery. All patients who underwent scoliosis correction had a progressive increase in the percentage of hip migration at a rate greater than that prior to scoliosis surgery. Similarly, patients who underwent a hip reconstruction procedure demonstrated a more rapid increase in their spine Cobb angles post surgery. There may be a relationship between hip subluxation/dislocation and scoliosis in CP patients. Surgery for either scoliosis or hip dysplasia may in the presence of both conditions lead to a significant and rapid worsening of the other. The possible negative implications on the overall functional outcome of the surgical procedure warrants careful consideration to both hip and the spine before and after surgical correction of either deformity. In selected cases there may be an indication for one procedure to follow soon after the other.
Highly active anti-retroviral therapy has transformed HIV into a chronic disease with a long-term asymptomatic phase. As a result, emphasis is shifting to other effects of the virus, aside from immunosuppression and mortality. We have reviewed the current evidence for an association between HIV infection and poor fracture healing. The increased prevalence of osteoporosis and fragility fractures in HIV patients is well recognised. The suggestion that this may be purely as a result of highly active anti-retroviral therapy has been largely rejected. Apart from directly impeding cellular function in bone remodelling, HIV infection is known to cause derangement in the levels of those cytokines involved in fracture healing (particularly tumour necrosis factor-α) and appears to impair the blood supply of bone. Many other factors complicate this issue, including a reduced body mass index, suboptimal nutrition, the effects of anti-retroviral drugs and the avoidance of operative intervention because of high rates of wound infection. However, there are sound molecular and biochemical hypotheses for a direct relationship between HIV infection and impaired fracture healing, and the rewards for further knowledge in this area are extensive in terms of optimised fracture management, reduced patient morbidity and educated resource allocation. Further investigation in this area is overdue.
Percutaneous drill epiphyseodesis is an effective method of achieving physeal ablation with no significant complications. While the growth remaining method is a crude estimate of the timing of epiphyseodesis, it was accurate in the majority of cases in this small series. The determination of skeletal age was found to be a useful adjunct to management in a small proportion of cases.
Purpose: To review the orthopaedic manifestations and document the results of surgical intervention. Material and Methods: A review of all 22 children currently attending a specialist scleroderma clinic was performed. Disease extent was measured in terms of percentage body surface area (BSA) affected and all orthopaedic abnormalities were documented. The outcome of surgical intervention was evaluated. Results: All children presented by the age of 12 and all but 2 had developed joint contractures of either the lower or upper limbs affecting function within 2yrs of diagnosis. Overall, lower limbs were more commonly affected than upper. Abdominal scleroderma led to a scoliosis in 75% of cases. The mean BSA affected was 35% (range 5-65%) with contractures more related to site of disease rather than extent. Pain was associated with lower limb contractures and loss of function with hand contractures. Limb length discrepancy (LLD) was common with a mean of 3cms (range 2-6.5cms). 8 children have had surgery. 7 developed wound healing problems. 50% of operations failed to correct the deformity and in a further 25% relapse has occurred. In the remaining 2 cases a good result was achieved. In addition, one epiphysiodesis has been performed and 3 are planned. Conclusions: This is the largest known review of children with linear scleroderma. Joint contractures are common but poorly managed by conservative methods alone. Surgical intervention is difficult but early defini-tive treatment is recommended with subsequent aggressive splinting during growth whilst the disease is active. LLD must be corrected.
The purpose of the study was to perform an independent assessment of the results of open reduction and internal fixation (ORIF) on a selected group of displaced intra-articular calcaneal fractures from two centres. It still remains controversial whether to manage intraarticular calcaneal fractures conservatively or operatively with few long-term results. The identification of patients who may benefit from the procedure is still undecided. Fifty fractures in 46 patients with a defined significant displacement of an intra-articular fracture of the calcaneum underwent ORIF by one of the two senior authors. Mean age at operation was 46 years and mean follow-up was 44 months. 88% of the injuries were due to a fall from a height. 30% of the patients had contralateral foot/ankle injuries, and 20% of the patients developed a superficial wound infection. The infection rate was significantly higher in patients whose surgery was delayed more than 14 days. All patients were independently reviewed after a minimum two-year follow-up. A clinical, radiographic and subjective assessment of the outcome was made. The results were correlated to the original fracture type. The mean Atkins score was 88 (out of 100). Bilateral injuries fared worse. Heel pain at follow-up correlated with a poor score. Atkins scores over 90 occurred in 77% of Saunders Type II, 50% in Type III, and 43% in Type IV fractures. 94% returned to work at a mean of 10 months post-injury. Three patients have undergone a subtalar arthrodesis – two for persistent pain and one for a significant malunion. One patient required a flap but there have been no cases of chronic osteomyelitis. In patients with significantly displaced fractures, ORIF is a worthwhile procedure with 90% of patients satisfied and 94% returning to work. Gross articular comminution does not preclude a good/excellent result if hindfoot alignment is restored. ORIF after fourteen days should be avoided due to the high risk of infection.

We have developed a clinical method for the graphic recording, analysis and planning of treatment of leg-length discrepancy during growth. Initially, the clinically determined discrepancy is plotted against the chronological age yearly, and then in late childhood at six-monthly intervals. CT and measurements of skeletal age are made in middle and late childhood to confirm the clinical findings. In a prospective study in 20 children, we observed that only eight had a linear increase in discrepancy. The observed pattern of increase was therefore used to estimate the mature discrepancy. Epiphyseodesis reference slopes were used to determine the most appropriate time and type of epiphyseodesis. In all children, the leg-length discrepancy at maturity was within 1 cm of the predicted amount. Changes in discrepancy due to leg lengthening or correction of deformity were also plotted graphically. We conclude that the clinical graphic method is simple to use, takes into account the varying patterns of discrepancy, and minimises radiation dosage.
We have studied the radiographic and CT features of 120 displaced intra-articular fractures of the calcaneum in order to define the pathological anatomy. In 96% of cases, the CT scans identified three main fragments: sustentacular, lateral joint and body. The sustentacular fragment was often rotated into varus, the lateral joint fragment into valgus and the body fragment impacted upwards, in varus and displaced laterally. The displacement of these fragments varied according to which of three fracture types was present, as defined by the composition of the fractured lateral wall of the calcaneum. In type 1 it was formed by the lateral joint fragment alone; in type 2 by both body and lateral joint fragments; and in type 3 by the body fragment alone. Fracture fragment displacement differs from that previously described, in that true uniform depression of the lateral joint fragment is rare.
The classification of intra-articular fractures of the calcaneum described in part I is related to an operative approach which allows accurate reduction and stable fixation of the fracture fragments. An extended lateral incision is used to avoid sural nerve damage and problems of soft-tissue healing. In type 3 fractures, access to the lateral joint fragment requires an osteotomy of the lateral wall, but after this the lateral joint fragment can be rotated out of the subtalar joint to allow transcalcaneal reduction of the medial wall. Reduction of the body fragment and lateral joint fragment on to the sustentacular fragment allows the three fragments to be stabilised by a 3.5 mm Y-shaped reconstruction plate. Our early results have been successful in terms of fracture reduction and the restoration of heel shape and joint congruity, but extended follow-up will be necessary to define the indications for this difficult procedure.
The results of treatment in 242 patients with intracapsular fractures of the neck of femur treated with Garden screws are presented with reference as to whether the screws were crossed or parallel. The incidence both of nonunion and of avascular necrosis was less in those fractures treated with parallel screws. The outcome was also superior if the reduction was good.
We reviewed 34 hindquarter amputations performed for malignant tumours around the hip from 1971 to 1988, classifying them as palliative or curative according to the resection margins or the presence of disseminated disease at the time of surgery. There were three peri-operative deaths, 12 palliative and 19 curative procedures. Ten patients died of disseminated disease within a year of surgery, eight of whom had had a palliative operation. Three patients died between one and five years after palliative surgery. One died of unrelated disease at nine years. Seventeen patients are disease free an average of 31 months from surgery, 16 after curative procedures. The median survival after palliative amputations was six months and the 5-year survival rate for curative cases was 83%.
