This study addresses a crucial gap in the knowledge of normative spinal growth in children. The objective of this study is to provide detailed and accurate 3D reference values for global and segmental spinal dimensions in healthy children under the age of 11. Radiographic spine examinations of healthy children conducted to rule out scoliosis were reviewed in four scoliosis referral centers in North America. All consecutive children aged three to eleven years old with EOS biplanar good quality x-rays, but without diagnosed growth-affecting pathologies, were included. Postero-Anterior and Lateral calibrated x-rays were used for spine 3D reconstruction and computation of vertebral body height and spine length. Median and interquartile range were calculated from cross-sectional data. Smooth centiles growth curves for 3D True Spinal Length (3DTSL) between T1 and S1, as well as for mid-vertebral heights of T5, T12 and L3, where fit and calibrated from data using the Lambda-Mu-Sigma method (GAMLSS package for R). This method automatically selects the best performing distribution from a familly of choices. Tables of centiles were then predicted from the computed models for selected ages. A total of 638 full spine examinations from asymptomatic patients were reconstructed in 3D, 397 in girls and 241 in boys. Medians and interquartile ranges were calculated for 3DTSL (T1-S1): 285 (24) mm, 314 (26) mm and 349 (31) mm, and for selected vertebral heights T5: 10 (1) mm, 11 (1) mm and 12 (1) mm, T12: 13 (2) mm, 14 (1) mm and 16 (2) mm, and L3: 14 (1) mm, 16 (2) mm and 18 (2) mm, respectively for the 3–6, 6–8 and 8–11 age groups. Centile curves ready for clinical use of the 3DTSL (T1-S1) and of the vertebral heights of T5, T12 and L3 as a function of age were derived for the 5, 10, 25, 50, 75, 90 and 95th centiles. In general, boys presented linear relationships between spinal dimensions and age, and girls presented more diverging trends with increased variance for older ages. Accordingly curves for boys follow the Normal distribution whereas those for girls follow the original Box-Cox-Cole-Green distribution. Model diagnostic tests (normally distributed residuals, adequate wormplots and |Z statistics| < 2) confirmed adequacy of the models and the absence of significant misfit. Accurate reference values were derived for spinal dimensions in healthy children. Spinal dimension charts showed that the spinal lengths and vertebral heights changed relatively constantly across the age groups closely resembling WHO total body height charts. The reference values will help physicians better assess their patients' growth potential. It could also be used to predict expected spinal dimensions at maturity or changes in pathologic conditions as well as to assess the impact of growth friendly interventions in the correction of spinal deformities

Introduction. Hip dysplasia is the most common congenital deformity of the musculoskeletal system. This is a pathology that brings the hip joint from subluxation to dislocation. Frequency of hip dysplasia − 16 children per 1000 newborns. Materials and Methods. Diagnostic methods of research are X-ray inspection which is necessarily carried out at internal rotation (rotation) of an extremity as lateral rotation of a hip on the radiograph always increases an angle of a valgus deviation of a neck. Surgical treatment is performed in the subclavian area of the femur. An external fixation device is applied and a corrective corticotomy is performed, and valgus deformity and anteversion are eliminated. The duration of treatment is 2.5–3 months. Results. Frequency of hip dysplasia − 16 children per 1000 newborns. We perform about 30 operations a year, including 60% girls and 40% boys. In addition, valgus deformity can be traced -. - in cerebral palsy. - after polio. - at progressing muscular dystrophies. - tumor in the area of the epiphyseal cartilage. At insufficient stability in a hip joint at insufficiently expressed roof of an acetabulum of rotational deformation of a neck of a hip, for prevention of a coxarthrosis and normalization of a ratio of articular ends operation detorsion-varying subvertebral corticotomy of a femur is shown. Conclusions. The operation is minimally invasive, with accesses of 5–6 mm, anatomical and topographical features are taken into account, which will eliminate damage to tissues, nerve trunks and the circulatory system

Introduction. Amputation or disarticulation is a reliable option for management of severe foot deformities and limb-length discrepancies, the surgical restoration of which are unpredictable or unfavourable. Of the various surgeries involving foot ablation, Syme's amputation is preferred for congenital deformities as it provides a growing, weight bearing stump with proprioception and cushioning. Materials and Methods. We reviewed data of all children who underwent Syme's amputation over the past 13 years at our institution. Surgical technique followed the same principles for Syme's but varied with surgeons. Results. Ten boys and ten girls, with an average age of 18 months and average follow up of 70 months were included in the study. The most common indication was fibular hemimelia. Wound complications were reported in three children, phantom pain in one, heel pad migration in two. None had wound dehiscence, flap necrosis, stump overgrowth, or calcaneal regrowth. None of this required surgical intervention. One child required an amputation at a higher-level secondary to a congenital malformation of nervous tissue in the affected leg. Prosthetic compatibility was 94.7 % and none used mobility aids. Six children participated in sports. Conclusions. Syme amputation is a safe and potentially advantageous procedure in children, with a low incidence of complications to offer patients with non-salvageable foot conditions. It offers good prosthetic use with minimal risk of complications and can offer patients a functional solution with only one surgical intervention throughout their childhood

Introduction. Femoral shaft fractures in children is a serious injury that needs hospitalization, with a high prevalence in the age group 6–8 years old. Various treatment options are available and with a comparable weight of evidence. Submuscular plating provides a dependable solution, especially in length-unstable fractures and heavier kids. We present a novel technique to facilitate and control the reduction intraoperatively, which would allow for easier submuscular plate application. Materials and Methods. We have retrospectively reviewed four boys and three girls; all were operated in one centre. Polyaxial clamps and rods were applied to the sagittally-oriented bone screws, the reduction was done manually, and the clamps were tightened after achieving the proper alignment in the anteroposterior and lateral fluoroscopy views. The submuscular plate was applied as described, then clamps and bone screws were removed. Results. The mean age at surgery was 13 years (range, 9–14). The mean body weight was 43.3 kg (range, 30–66). There were five mid-shaft fractures, one proximal third and one distal third. There were Four type A fractures, two type B and one type C. Four patients had road traffic accidents while three had direct trauma. The mean preoperative haemoglobin concentration 12.5 g/dl (range 11.3–13 g/dl). No blood transfusion was needed intraoperatively or postoperatively. The operative time averaged 122 minutes, and the mean hospital stay was one (range 1–4 days). The patients reported no pain at a mean of 1.5 weeks (range, one-three weeks). All fractures united at a mean of 8.7 weeks (range 6–12 weeks). No wound healing problems nor deep infections happened. The knee joint range of motion was full in all patients at six weeks postoperatively. There was no mechanical irritation from the inserted plate. At the final follow-up, all fractures united without malalignment nor length discrepancy. Conclusions. External fixator-assisted internal fixation of pediatric femoral fractures would facilitate the accuracy and control of fracture reduction and allow minimally invasive percutaneous osteosynthesis. Our study has shown a decrease in operative time, and an accompanying reduction in length of inpatient stay, prolonged need for analgesia and post-operative rehabilitation

Distal femoral physeal fractures can cause of growth distrurbance which frequently requires further surgical intervention. The aim of this study was to determine if tibial tuberosity ossification at the time of injury can predict further surgery in patients who have sustained a physeal fracture of the distal femur. We retrospectively investigated all patients who had operative treatment for a distal femoral physeal fracture at a paediatric level one trauma center over a 17 year period. Logistic regression analysis was performed investigating associations between the need for further surgery to treat growth disturbance and tibial tuberosity ossification, age, Salter Harris grade, mode of fixation or mechanism of injury. 74 patients met the inclusion criteria. There were 57 boys (77%) and 17 girls (23%). The average age at time of injury was 13.1 years (range 2.-17.1 years). Following fixation, 30 patients (41%) underwent further surgery to treat growth disturbance. Absence of tibial tuberosity fusion to the metaphysis was significantly associated with need for further surgery (p = < 0 .001). Odds of requiring secondary surgery after tibial tuberosity fusion to metaphysis posteriorly (compared with not fused) were 0.12, 95% CI (0.04, 0.34). The estimate of effect of tibial tuberosity ossification on reoperation rates did not vary when adjusted for gender, mechanism, fixation and Salter Harris grade. When accounting for age, the odds of further operation if the tibial tuberosity is fused to the metaphysis posteriorly (compared with not fused) were 0.28, 95% CI (0.08, 0.94). Tibial tuberosity ossification stage at time of injury is a predictor of further surgery to treat growth disturbance in paediatric distal femoral fractures. Children with distal femoral physeal fractures whose tibial tuberosity was not fused to the metaphysis posteriorly were 8.3 times more likely to require further surgery

Osteomyelitis and septic arthritis are common pathologies in young children. Because of their skeletal immaturity, children are particularly vulnerable to orthopaedic complications, including limb-length discrepancies, angular deformities, chondrolysis, etc. The primary objective of this study was to review the clinical follow up and outcomes of paediatric patients diagnosed with osteoarticular infections. The secondary purpose was to look for significant differences in the clinical characteristics between the one with and without complications. Patients' medical charts, hospitalised between 2010 and 2016, were retrospectively reviewed. The inclusion criteria were: patients (1) aged of less than 10 years old (2) treated and followed for osteomyelitis of long bones of upper and lower extremities and/or septic arthritis (3) with at least one year of radiological follow up. The exclusion criterion was: (1) any concomitant chronic diseases. The information collected included demographic and clinical data. A late sequela was defined as a limb-length discrepancy superior to 5 mm or an abnormal articular angulation of more than 5°, or a symptomatic chondropathy. Patients were separated in two groups: with and without complications. Chi-square tests were used for categorical variables and Mann-Whitney U tests for continuous data in order to establish significant differences between both groups. Of the 401 patients with osteomyelitis and/or septic arthritis treated in our tertiary paediatric hospital over 7 years, 50 met the inclusion criteria. There were 24 girls and 26 boys. The etiological agent was identified in 56% of the cases. Staphylococcus aureus was the predominant causal pathogen (50%), followed by Kingella kingae (19.2%). The mean follow up was 780 days. Six out of 50 (12%) patients had physeal or chondrolytic complications at the latest follow-up. The only significant difference between the 2 groups was the delay between onset of symptoms and initiation of antibiotic therapy (P = 0.039). Only 12.5% of the patients were followed up at least one year. In the population of 50 skeletally immature patients without comorbidities, 12% had a sequela. The delay in initiating antibiotic treatment was significantly longer in the group with the presence of sequelae. The results of this study reveal that there were low rates of outpatient follow-up reaching more than a year after an osteoarticular infection, thus raising the question about the importance of a follow up after such a diagnosis. Twelve percent of the patients had a growth or chondrolysis complication and this might be related to the delay before initiating antibiotic treatment

Despite recent advances in the management of slipped capital femoral epiphysis (SCFE), controversy remains about the treatment of choice for unstable slips. Surgical dislocation and open reduction has the advantage of identifying and preserving the blood supply of femoral head thereby potentially reducing the risk of avascular necrosis, (AVN). There is large variation in the literature from several small series about reported AVN rates ranging from two to 66% for unstable SCFE treated with surgical dislocation. The aim of our study was to analyze our experience with acute open reduction and internal fixation of unstable acute and unstable acute on chronic slips using the technique of surgical dislocation described by Professor Reinhold Ganz. A retrospective review of 11 patients (12 hips) treated by surgical dislocation, reduction and pinning as the primary procedure for unstable acute and unstable acute on chronic SCFE in a tertiary referral children's hospital was undertaken. This represents the entire series treated in this manner from September 2007 to January 2018. These procedures were performed by a team of Orthopaedic surgeons with significant experience performing surgical dislocation of the hip including patients with chronic SCFE, Perthes' disease, impingement and acetabular fractures. Demographic data, intraoperative records, postoperative notes and radiographs including details of subsequent surgery were reviewed. There were seven boys and four girls with mean age of 13.4 years, range 11 to 15 years at the time of surgical dislocation. Out of 12 hips, two had acute unstable slip while the remaining 10 had acute on chronic unstable slip. Six patients had good or excellent results. The remaining six patients developed AVN of which three patients had total hip replacement at six months, 17 months and 18 months following primary procedure. Seven patients required more than one operation. Three patients lost their correction and required re fixation despite surgical dislocation, reduction and fixation being their primary procedure. This series demonstrates a high percentage of AVN (50%) in severe unstable SCFE treated with surgical dislocation despite careful attention to retinacular flap development and intra operative doppler studies. This is in direct contrast to our experience with subcapital reorientation with surgical dislocation in stable slips where excellent results were achieved with a low rate of AVN. Pre-operative imaging with MRI and perfusion studies may identify where ischemia has occurred and might influence operative treatment. Based on our results, we do not recommend routine use of surgical dislocation in unstable SCFE. This technique requires further scrutiny to define the operative indications in unstable SCFE

Predictions of lower limb growth are based upon historical data, collected from patients who had coexistent poliomyelitis. By utilising standardised longitudinal prospective European data, our objective was to generate superior estimates for the age and rate at which lower limb skeletal maturity is reached; thus improving the timing of epiphysiodesis, for the management of leg length discrepancy. The Avon Longitudinal Study of Parents and Children of the 90s (ALSPAC) is a longitudinal cohort study of children recruited antenatally 2. Using a previously validated Multiplier Method, a sequence of leg length multipliers were calculated for each child. 15,458 individuals were recruited to the ALSPAC study; and of those whose growth was measured, 52% were boys and 48% girls, each with an average of eight recording episodes. 25,828 leg length multiplier (LLM) values were calculated with final recordings taken at a mean age of 15.5 years. From this data, the age at which girls reach skeletal maturity (LLM=1) is 11 months later than previously calculated and for boys nearly 9 months earlier. With nearly 4000 more children recruited in this cohort than preceding studies, this study brings increased power to future leg length calculations

Aims. Comparison of the outcome between the supine or prone positioned child with a supracondylar humerus fracture by measuring anaesthetic and operating time, functional outcomes and complications. Methods. All children with isolated Gartland 2 and 3 supracondylar humerus fractures were who were admitted to our institute, were asked to participate in the the study. For surgery, the participating children were either operated on in a ‘supine’ or ‘prone’ position. The children were randomly allocated to either the ‘supine’ or ‘prone’ position. The fractures were preferably treated by closed reduction and percutaneous pinning with k-wires. However, if the fracture proved difficult to reduce, we proceeded to open reduction via medial and lateral approach. All fractures were stabilized with one medial and one lateral k-wire. The children were immobilized in a reinforced above elbow back-slab. Total anaesthetic and surgical time were meticulously recorded. Patients were followed up in our outpatient clinic at one week, four weeks (at which time the k-wires were removed). Three months post operatively, elbow extension, flexion and total range of movement was assessed in all children. Results Twenty children with isolated Gartland 2 and 3 supracondylar humerus fractures were included in this study. Nine children (5 ± 1 years, 7 boys and 2 girls) were operated on in a prone position, while 11 children (6 ± 2 years, 10 boys and 1 girls) were operated on in a supine position. Results. The anaesthetic time was significantly longer in the prone (20 ± 8 min) than in the supine position(10 ± 3 min) (p = 0.001). In line with this, surgical time showed a tendency to also be longer in prone (44 ± 36 min) than supine position (18 ± 18 min) (p = 0.08). No differences between prone and supine operated children was found for elbow extension (4.4 ± 7.7° vs. 3.6 ± 7.1°, respectively (p = 0.81)), elbow flexion (129.4 ± 8.8° vs. 127.0 ±8.8°, respectively (p = 0.67)) and/ or elbow range of motion (125.0 ± 16.0° vs. 124.1 ± 14.6°, respectively (p = 0.90)). Conclusion. As no differences were found in elbow mobility 3 months post-operatively and anesthetic and surgical time tends to be longer in a prone position, this study suggests that operating children with Gartland 2 and 3 supracondylar humerus fractures in a supine position is more favorable.

Ankle sprains are common athletic injuries, with a peak lifetime incidence between the ages of 15 and 19 years, especially in young males. However, an unclear history, an imprecise physical exam, and unhelpful radiographies lead to frequent misdiagnosis of paediatric ankle traumas, and subsequently, inappropriate treatment. Improper management may lead to residual pain, instability, slower return to physical activity, and long-term degenerative changes. The purpose of this study was to evaluate the initial management and treatment of acute paediatric ankle sprains at our center, a tertiary care paediatric hospital. Our hypothesis was that the initial diagnosis is often incorrect, and treatment varies considerably amongst orthopaedic surgeons. We conducted a retrospective study of all cases of ankle sprains and Salter-Harris one (SH1) fractures referred to our orthopaedic surgery service between May and August 2014. Exclusion criteria included ankle fractures other than SH1 types, and cases where treatment was initially undertaken elsewhere before referral to our service. Patients were evaluated on a clinical and radiographic basis. Primary outcome was the difference between initial and final diagnosis. Secondary outcome was variation in immobilisation duration for each diagnosis. The main variables we considered were age, sex, mechanism of trauma, referral delay, patient symptoms, physical exam findings, radiographic findings, type and duration of immobilisation, prescription of any medication, and referral to physical therapy. A total of 3047 patients were reviewed and 31 cases matched our inclusion criteria, comprised of 17 girls and 14 boys, with a mean age of 10.4 years. Patients were seen at a mean of 10.3 days after injury. Initial diagnosis was SH1 fracture in 20 cases, acute ankle sprain in 8 cases, and uncertain in 3 cases. Final diagnosis was SH1 fracture in 11 cases, acute ankle sprain in 13 cases, uncertain in 5 cases, and other in 3 cases. During follow up, 48.5% of cases saw a change in diagnosis. Forty five percent (9/20) of cases initially diagnosed as SH1 fractures proved to be incorrect, with 55.5% (5/9) of these being ultimately diagnosed as acute ankle sprains. Amongst cases initially diagnosed as acute ankle sprains, 37.5% (3/8) received a different final diagnosis. Duration of immobilisation was significantly different between acute ankle sprain and SH1 fracture groups, with an average of 17.3 days and 26.1 days, respectively. Physical therapy was prescribed to 33.3% of acute ankle sprains and 9.1% of SH1 fractures. Initial distinction between acute ankle sprains and SH1 fractures can be difficult in paediatric ankle trauma. Case management and specific treatments vary considerably, as there is neither an evaluation algorithm nor consensus on treatment of these paediatric pathologies. This study reinforces the need to develop a systematic diagnostic and treatment protocol for paediatric ankle sprains

Acute osteomyelitis and septic arthritis are uncommon diseases in childhood that affect previously healthy children. A high index of suspicion, early diagnosis, initiation of appropriate antibiotic treatment and surgical intervention are essential for a good outcome. The aim of our study was to evaluate our approach, clinical signs and the outcome of the diseases. We retrospectively analyzed clinical, laboratory and microbiologic data in children hospitalized for acute haematogenous osteomyelitis or septic arthritis at the Department of Orthopaedic surgery in a 10-year period (from 2003 to 2013). Follow-up of outpatients was continued for at least 1 year or until the full recovery. Acute haematogenous osteomyelitis or septic arthritis were confirmed in 22 patients, 14/22 (64%) had osteomyelitis and 8/22 (36%) arthritis, 16/22 (73%) were boys. The mean patient age was 9,3 years (SD:3,5), the median of the hospitalization was 32 days (IQR:13 – 60 days). In children with osteomyelitis 10/14 (72%) had affected lower limb and in 4/14 (28%) the spine was affected. Six (80%) children had septic arthritis of the knee, hip joint was affected in one child and sacroiliac joint in one as well. We obtained blood cultures in 19/22 (86%) patients, bone biopsy was performed in 14/22 (64%). All infections were monomycrobial, Staphylococcus aureus was the most common pathogen, as expected. In one patient the cause of the osteomyelitis was Panton-Valentine leucocidin (PVL) producing S. aureus. The characterics are presented in Table 1. All affected children recovered completely. We observed 22 cases of pediatric bone and joint infections in a 10-year period. The most common pathogen was Staphylococcus aureus, as expected, althogh in more than half of cases no pathogens were found. One child suffered from osteomielitis caused by S. aureus strain producing PVL. We observed higher proportion of spine invovelment than previously reported in the literature

Meningococcal infection is the most common infective cause of death in children and causes significant morbidity in survivors. Patients admitted to the Paediatric Intensive Care Unit (PICU) of the Bristol Royal Hospital for Children from 01/01/2001 to 31/12/2012 with a primary diagnosis of meningococcal septicaemia were reviewed. A total of 10 (7.7%) of 130 patients developed orthopaedic complications. Those affected were significantly younger (p < 0.05), remained on PICU for longer (p < 0.001) and boys had a greater risk of developing orthopaedic complications (risk ratio: 3.1; 95% CI: 0.69–14.14). 9 patients required an amputation, 16/22 (72.7%) in the lower limb. Patient requiring amputation had multiple limb involvement. 48 growth plate abnormalities were identified in 8 patients, 39 (81.3%) in the lower limb, most commonly in the distal tibia. This study has identified a high incidence of musculoskeletal morbidity. Close surveillance of these patients is recommended to identify growth arrest before the onset of clinically significant deformity. It identifies a defined population of patients with meningococcal septicaemia using admission to PICU as an entry criterion allowing accurate determination of the incidence and characteristics of the skeletal consequences of this condition

Aim:. To review the use of traction x-rays under anaesthesia in Late Onset Scoliosis to correlate traction x-ray flexibility and postoperative correction using posterior nonsegmental all pedicle screw constructs. Methods:. Prospective study. Preoperative anteroposterior, lateral and side bending x-rays were done and Cobb angles were measured. Intraoperatively, traction anteroposterior x-rays were taken under anaesthesia and Cobb angles were measured. All patients underwent nonsegmental posterior all pedicle screw construct correction using Biomet implants. Cobb angles greater than 60 degees were included in the study. Calculations were done including correction rate, traction flexibility and traction correction index. Results were entered onto an excel spreadsheet and analyzed using Statistica software. Results:. 16 patients were studied, 3 boys and 13 girls, average age 14, ranging from 8 to 17 years. Preoperative Cobb angles were mean 82 (60 to 105) degrees. Traction x-rays mean Cobb angle was 42 degrees with mean traction flexibility rate 49%. Mean correction rate was 65% and mean traction correction index 106. Preoperative Cobb angles correlated with traction flexibility with a p value of 0.01. Traction x-rays Cobb angle correlated with the traction correction index (p = 0.003), postoperative x-rays (p = 0.000) and also with correction rate (p = 0.024). There was no correlation between preoperative Cobb angle and correction rate. Conclusion:. Traction x-rays under anaesthesia in late onset scoliosis are a good predictor of postoperative correction with posterior nonsegmental all pedicle screw constructs in curves greater than 60 degrees

Background. The gold standard of care of clubfoot is the Ponseti method of serial manipulation and casting, followed by percutaneous tendo-achilles tenotomy. In our setting, registrars work in district hospitals where they run Ponseti clubfoot clinics with little or no specialist supervision. They use the Pirani score to serially assess improvement of the deformity during casting and to determine whether the foot is ready for tenotomy. Purpose of Study. To test the inter-observer reliability of the Pirani score, and whether it can be used by non-specialist doctors running Ponseti clubfoot clinics. Methods. Ethics permission was obtained from our institution. This is a prospective study where patients under the age of one year with idiopathic clubfoot were recruited from clubfoot clinics at our institution, over a period of four months. Following a training session using the original description of the score, each foot was independently assessed using the Pirani score by two paediatric orthopaedic surgeons, two orthopaedic registrars and two medical officers. The inter-observer reliability was assessed using the Fixed-marginal Kappa statistic and Percentage agreement. The first 15 feet were used as a learning curve, and hence excluded from final analysis. Results. 73 feet in 37 patients with idiopathic clubfoot (25 boys, 12 girls) under the age of 1 year were included in the study. The Kappa statistic and percentage agreement for the six variables of the Pirani score were determined. Whilst the overall agreement was determined by the Kappa statistic to be slight to fair, the two consultants were found to have a higher inter-observer reliability than the registrars and medical officers. Conclusion. Our results conflict with previously published studies in that the inter-observer reliability of the Pirani score was poor. In addition, we feel that this score cannot be reliably used by non-specialist doctors running Ponseti clubfoot clinics. NO DISCLOSURES

Purpose of study:. Congenital hallux varus is a rare condition presenting with medial deviation of the big toe. It consists of 2 variants: classical congenital hallux varus caused by an abnormal metatarsal-phalangeal articulation, and a more recently described variant due to a “bracket physis” of the first metatarsal. Our aim was to perform an audit of the spectrum of presentation of congenital hallux varus with its management and complications in our unit over a five year period. Description of methods:. A retrospective review of congenital hallux varus treated by a single surgeon was performed. Clinical notes, photographs and x-rays were reviewed. Two surgical methods of treatment were used as directed by clinical and radiological findings. Summary of results:. Four patients with congenital hallux varus were identified. Three had bilateral involvement, i.e. seven feet were treated. The ages of the patients ranged from 1 to 9 years, with 2 boys and 2 girls receiving treatment. In two patients (4 feet) the deformity was associated with pre-axial polydactyly. One patient had associated hand deformities. Only one of our four patients had a “bracket physis” and was treated with a metatarsal osteotomy. The other three patients (6 feet) were treated by soft tissue realignment using the Farmer procedure. One patient who had bilateral Farmer procedures subsequently developed a bunion over the 1st metatarso-phalangeal joint of one foot due to uncovering of the metatarsal head. No complications or recurrences were recorded in the other three patients on follow up visits. Conclusion:. Careful clinical and X-ray analysis is important to determine the type of congenital hallux varus and which method of surgical treatment is appropriate. Long term follow up is required to identify subsequent deformities

Purpose of Study. In children with spastic diplegia, surgery for equinus has a high incidence of both over and under correction. We wished to determine if conservative (mainly Zone 1) surgery for equinus gait, in the context of multilevel surgery, could result in the avoidance of calcaneus and crouch gait as well as an acceptable rate of recurrent equinus, at medium term follow-up. Description of Methods. This was a retrospective, consecutive cohort study of children with spastic diplegia, between 1996 and 2006. All children had distal gastrocnemius recession or differential gastrocsoleus lengthening, on one or both sides, as part of Single Event Multilevel Surgery. The primary outcome measures were the Gait Variable Scores (GVS) and Gait Profile Score (GPS) at two time points after surgery. Summary of Results. Forty children with spastic diplegia, GMFCS Level II and III were eligible for inclusion in this study. There were 25 boys and 15 girls, mean age 10 years at surgery. The mean age at final follow-up was 17 years and the mean postoperative follow-up period was seven years. The mean ankle GVS improved from 18.5° before surgery to 8.7° at short term follow-up (P<0.005) and 7.8° at medium term follow-up. Equinus gait was successfully corrected in the majority of children with a low rate of over-correction (2.5%) but a high rate of recurrent equinus (35.0%), as determined by sagittal ankle kinematics. Conclusion. Surgery for equinus gait, in children with spastic diplegia, was successful in the majority of children, at a mean follow-up of seven years, when combined with multilevel surgery, orthoses and rehabilitation. No patients developed crouch gait and the rate of revision surgery for recurrent equinus was 12.5%. NO DISCLOSURES

Introduction. Osteochondral defects of the knee may occur following patella dislocation or following direct trauma or twisting injuries to the knee in adolescents. Often a diagnostic and therapeutic challenge, if these lesions are left, posttraumatic osteoarthritis may occur. This retrospective single centre study presents the short-term results following operative fixation of osteochondral fragments of the knee using Omnitech ® screws. Method. All skeletally immature patients presenting with an osteochondral fracture of their femur or patella confirmed on xray and MRI were identified. Arthroscopic evaluation of the osteochondral defect was performed followed by open reduction and internal fixation of the osteochondral fragment using Omnitech ® screws. A standard postoperative rehabilitation protocol was followed. Patients were evaluated at follow-up using a Knee Injury and Osteoarthritis Outcome Score (KOOS). Results. Eight patients were identified. The mean age at time of injury was 15 years (range 14–16) for two girls and 14.4 years (range 13–16) for six boys. The lateral femoral condyle was involved in six cases and patella in two cases. At mean follow up of 14 months (range 1–38) there was no revision for failure and no postoperative complications. The KOOS score (out of 100) at final follow up was subdivided as follows; Pain, 93 (range 81–100), other symptoms, 77 (range 36–100), function in daily living (ADL), 97 (range 84–100), function in sport and recreation, 84 (range 55–100) and knee related quality of life, 79 (range 44–100). Discussion. The short-term results of using Omnitech® screws are promising. Subchondral screw placement with adequate compression of the osteochondral fragment is achievable with Omnitech ® screws. Seven patients are back to their pre-injury sporting activity and one patient is currently undergoing postoperative rehabilitation, one month following surgery

Introduction. Lateral humeral condyle fractures account for 17% of the distal humeral condyle fractures. They affect children between 5 and 10 years of age. Recent reports advocate closed reduction and internal fixation for the less displaced fractures. Methods. We retrospectively reviewed children treated with open reduction internal fixation of these fractures at a single institution over a period of 13 years. All cases of lateral humeral condyle fractures treated with ORIF were identified through the trauma register. Case notes and radiographs were retrieved. Fracture classification, mode of fixation, time to union, and clinical examination at latest follow up were reviewed. Results. 105 lateral condyle fractures were identified. 76 (72%) in boys and 29 (28%) in girls. Average age was 6.2 years. 92 were Milch type 2 and 13 Milch type 1. According to the Jacobs classification for displacement 9 were type I, 33 Type II and 63 type III. All fractures were treated with open reduction and fixation with K-wires. Average time to union (radiologic) was 34 days. Mean follow up was 39 months. Hypertrophy of the lateral condyle in follow up radiographs was documented in 45 cases (42%). Cubitus Varus was documented in 7 cases (7%). None of the children complained of painful range of movement at latest follow up. There was one case of superficial infection of the K-wires and one case of delayed union. Discussion. Open reduction internal fixation is the established management of lateral humeral condyle fractures. This series confirms the consistently good results of open reduction. Compared to recent reports of closed reduction internal fixation, this series demonstrates good results with no complications directly relating to the open reduction technique

The Pelvic Support Osteotomy (PSO) or Ilizarov Hip Reconstruction(IHR) is well described for the treatment of septic sequelae of infancy. The purpose of this study was to clinically, functionally and radiographically assess our short-term results of this procedure. 25 patients (16 boys, 9 girls) who had undergone a IHR using the Ilizarov/TSF construct over a period of 10 years for a variety of pathologies were reviewed. The mean age at surgery was 15 years 4 months. The pre-operative diagnoses were SCFE(10), hip sepsis (6), DDH (6) and Perthes (3). All had significant leg length discrepancies, 16 had a painful stiff hip, 6 had a painful mobile hip and 3 had a painless unstable hip. At surgery, a mean measured proximal valgus angle of 51° and a mean extension angle of 15° was achieved. Distal femoral lengthening averaged 4.2 cm and distal varus correction was a mean of 8°. The mean fixator time was 173 days. At a mean of 2 years and 7 months follow-up the lower-extremity length discrepancy had improved from a mean of 5.6 cm apparent shortening to 2.3 cm. Trendelenberg sign was eliminated in 18/25 cases. Improvements in range of hip movements and gait parameters were observed. Stance time asymmetry, step length asymmetry, pelvic dip and trunk lurch improved significantly. One patient had conversion to a total hip replacement after 7 years, 4 patients required re-do PSO due to remodelling of the proximal osteotomies, two had heterotopic ossification and two had significant knee stiffness due to lack of compliance. The early results of IHR are encouraging to equalise limb lengths, negate trendelenburg gait, provide a mobile hip with a reasonable axis and the possibility of conversion to THR in the future if needed. Complications need to be anticipated and the effects of remodelling and maintaining adequate knee range of motion must be emphasised

A retrospective descriptive preliminary study on early experience using all pedicle screw correction. Pedicle screw fixation enables enhanced correction of spinal deformities. However, the technique is still in early development in our clinic. Tends of the scoliosis patient to come in late ages make maximum correction failed. A total 16 patients are subjected to pedicle screw fixation for spinal deformities were analyzed descriptively as an early follow-up in the last two-year. 14 patients are girl and 2 are boys. The age range between 12 to 18 year. 8 are Kings type II and 8 are Kings type III, 212 screws were inserted between Th3 – L2 (14-18 screws per-patient), all concave pedicles were inserted with screws but in convex side every two or three pedicles were inserted. The position of screws was analyzed using the post-operative plain X ray film. Before surgery the mean deformity measurement are 52.56° (range, 42-72°, correction achieved was 18° (range 10-34%, it was correlated to 68% achievement (range, 53-80%). All patients are happy with their image improvement. In total 212 screws inserted, 28 screws are malpositions (13.2%), but no clinical complication recorded. In this early experience using all pedicle screw scoliosis surgery, all patients are happy with the results although the correction only 53-80(. More patients are needed to improve this achievement
