Introduction. Trochleoplasty is an effective surgical procedure for patients with severe trochlear dysplasia and recurrent patella instability. Previous work has suggested patients demonstrate early improvements in knee function and quality of life. However, concerns regarding longer term outcomes due to the development of stiffness and patellofemoral osteoarthritis remain a concern for these patients. Our aim was to assess mid-term patient-reported outcome and quality of life measures for trochleoplasty performed at a single centre for severe trochlear dysplasia. Methods. Retrospective review of 28 knees (23 patients) having undergone trochleoplasty for severe trochlear dysplasia were reviewed. Due to the non-parametric nature of the data, median and interquartile range (IQR) were determined for pre-operative and mid-term follow-up scores. Statistically significant differences between groups were assessed using paired Wilcoxon-signed rank test with statistical significance set at p<0.05. Data were analysed using a statistical software package (IBM® SPSS® Statistics 26.0). Results. Median time from surgery to follow-up for all patients in the series was 5.3 years (IQR 3.9 – 7.0 years). Median pre-operative Kujala score improved from 57.0 (IQR 45 – 66) to 96.3 (IQR 83 -100). Median pre-operative IKDC score improved from 42.6 (IQR 35.9 – 51.3) to 92.6 (IQR 71.6 – 98.7). Median EQ-5D score also improved from 0.691 (IQR 0.414 – 0.727) to 1.000 (IQR 0.8178 – 1.000). Improvement in Kujala scores, IKDC scores and EQ-5D were all statistically significant with p<0.001 in all domains. Discussion. Our data suggests patients experience significant improvements in knee function and quality of life following trochleoplasty surgery for severe dysplasia. We demonstrate an absolute improvement in scores at a mean of 5.3 years follow-up of 39.3 points for Kujala, 50 for IKDC and 0.309 for EQ-5D. Minimal clinically important differences (MCID) have been reported to be in the region of 10 for the Kujala score, 8.8–15.6 for IKDC and 0.085 for EQ-5D. Our data shows improvements which far exceed the published MCID, suggesting trochleoplasty confers a large treatment effect and patients benefiting from sustained improvements in knee function and overall quality of life at mid-term follow-up. Conclusion. Following trochleoplasty for severe trochlear dysplasia, patient reported outcomes demonstrate continued improvements in knee function and quality of life at mid-term (5-year) follow-up. There is a large absolute treatment effect which likely impacts on both physical and psychological wellbeing for these patients. Continued surveillance of patient reported outcomes in this clinically complex cohort is indicated

Background. Fibrous dysplasia is a developmental anomaly of bone formation that may exist in a monostotic or polystotic form. Surgical treatment is considered advisable only with presence of significant or progressive deformity or persistent pain. Early surgery is indicated before the tumor expands or fracture occurs. Methods. We reviewed a series of 21 patients, 14 had monostotic whereas 7 had polystotic fibrous dysplasia. There was no case of Mc Cune Albright. We treated all of these patients with curettage and corticocancellous bone graft and also fixation with reconstruction nails. Follow up ranged between 1 and 5 years. Functional and radiographic outcomes were scored. Results. Russel Taylor IM nail and Gamma nail were used in 11 and 10 patients, respectively. Their mean age at the time of diagnosis was 28 years for monostotic for of the disease and 20 years for polystotic ones. Postoperatively, All patients had good bone healing and complete incorporation of the implanted graft, although it last longer in the case of corrective osteotomy for severe varus. Using of Gamma nail was easier for us in addition to shorter operation time. Up to now, no case of recurrency or pathologic fracture has been seen in our patients. Chronic hip pain was the most common problem in these patients but they reported no restriction of activity of daily living. Conclusion. Clinical results of reconstruction nails were safe and satisfactory in patients with fibrous dysplasia of proximal femour

Introduction

Metal-on-metal hip resurfacing (MOMHR) is a good surgical indication for young active patients. However, it cannot be used in patients with an excessively short femoral head/neck. To address these cases, a new surgical technique has been developed comprising femoral head augmentation using impacted morcellized bone grafts.

Methods

32 osteoarthritis patients who had severe congenital insufficiency of the femoral head/neck were treated with MOMHR combined with femoral head augmentation. Mean patient age was 49 ± 9 years (18–66). The required amount of augmentation was calculated on preoperative X-rays and confirmed during surgery. Using specially designed instrumentation, bone chips produced while reaming the socket and trimming the head were impacted onto the head to achieve the desired reconstruction and lengthening. Finally, the femoral component was cemented.

Aim

The purpose of this study was to analyze the patellofemoral kinematics in neglected adult developmental dysplasia of the hip patients with patellofemoral symptoms and tried to clarify the affect of the severity of dislocation, the amount of limb length discrepancy, the deviation of mechanical axis and the changes in femoral anteversion on patellofemoral alignment.

Methods

The dynamic patellofemoral CT results of 39 patients with DDH suffering from knee pain were reviewed. The mean age was 40.07 (range: 22–61). 14 of them were bilateral and 25 were unilateral neglected DDH patients. The CT results of 12 patients suffering from unilateral patellofemoral pain following the treatment of locked intramedullary nailing was taken as control group. In this patients atraumatic and asymptomatic normal site was taken as control group.

Patellofemoral instability (PFI) is a common cause of knee pain and disability in the paediatric population. Patella alta, lateralised tibial tubercle, medial patellofemoral ligament (MPFL) deficiency, genu valgum and trochlear dysplasia are well known risk factors. A prospective database was created including patients referred through our physiotherapy pathway following first-time patella dislocation. Patella alta and lateralisation of the tibial tuberosity was treated with a Fulkerson-type tibial tubercle osteotomy(TTO). Medial patellofemoral ligament was reconstructed using quads tendon autograft pull-down technique. A modified Sheffield protocol was used postoperatively allowing weightbearing in a hinged knee brace. Forty patients were identified with 8 patients having bilateral presentations. Male to female ratio was 12:28 with an age range of 4–17 years. Eight patients had congenital PFI, five patients acquired PFI through traumatic patella dislocation and twenty-seven patients developed PFI from recurrent dislocations. Structural abnormalities were found in 38(95%) of patients. Patella alta (Caton-Deschamps index >1.2) was identified in 19(47%) patients, genu valgum in 12(30%) patients, increased tibial tubercle-trochlear groove distance(TT-TG>20mm) was present in 9(22.5%) patients and persistent femoral anteversion(> 20 deg) in 7(17%) patients. Eight patients were treated with TTO and MPFL reconstruction, three patients with MPFL reconstruction alone and five patients had guided growth for genu valgum correction. Ten patients are awaiting surgery. No postoperative patients had recurrence of PFI at their latest follow up. PFI is a common problem in the adolescent paediatric population with identifiable structural abnormalities. Correcting structural pathology with surgery leads to predictable and safe outcomes

Background:. Leg length discrepancy related to absence of the femoral head with proximal migration of the femur presents a treatment dilemma. Late sequelae of neonatal hip sepsis and chronic hip dislocation due to developmental dysplasia are the most common causes. Traditional teaching dictates that the hip is stabilised prior to limb lengthening. Reconstructive options alter the shape of the proximal femur which complicates future surgery. Methods:. We retrospectively reviewed 3 cases of femoral lengthening with an ‘unstable’ hip without prior stabilization. The aetiology was neonatal hip sepsis in 2 cases and chronic hip dislocation due to developmental dysplasia in 1 case. Lengthening was performed with the use of a retrograde Precice lengthening nail. Results and Discussion:. The desired length (range 5.5 to 6cm) was achieved in all patients without migration of the proximal femur. In all cases patient satisfaction was high with the lengthening and the ability to abort shoe raises. There was an improvement in gait pattern in all patients. Conclusion:. Femoral lengthening is possible without prior stabilisation of the hip in so called ‘unstable’ hip situations. The proximal femoral anatomy is not further altered and future salvage procedures such as a total hip replacement are not compromised

Background. Disruption of the normal relationship between the proximal tibia and fibula is seen in a number of different conditions such as skeletal dysplasias and post-infective deformity, as well as the consequence of lengthening procedures. Radiographic indices for the tibio-fibular relationship at the ankle have been described, but no similar measures have been reported for the proximal articulation. Aim. The purpose of this study was to investigate the normal radiographic relationship between the proximal tibia and fibula in children to determine the normal range and variation. Methods. Our radiology database was used to identify a sample of 500 normal anteroposterior radiographs of paediatric knees. All radiographs were reviewed by a single observer. The distance from the corner of the lateral tibial plateau to both the proximal tibial (PT) and fibular physes (PF) were measured, and a ratio of the two calculated (PF/PT). The process was repeated with a sample of 100 radiographs by the same observer, and a second independent observer in order to calculate intra-and inter-observer reliability. Results. The age range of patients in this study was 4–16 years, with mean age 12.7. The mean PF/PT ratio was 1.7 (standard deviation 0.2, range 1.3–2.0). Intra-observer reliability was 100% and inter-observer reliability was 97.8%. Conclusion. The results of this study demonstrate that in the normal paediatric knee, there is a consistent relationship between the position of the proximal tibial and fibular physes, with a small range of variation. The PF/PT ratio is a simple and reliable way of assessing the relationship between the proximal tibia and fibula in children, using a standard anteroposterior radiograph. This ratio could be very useful in the diagnosis and planning of surgical management of a number of different causes of tibial and fibular deformities in children

Background. Several risk factors for the development of osteonecrosis following treatment of developmental dislocated hip have been reported. The need for further research with a large-enough sample size including statistical adjustment of confounders was demanded. The purpose of the present study was to find reliable predictors of osteonecrosis in patients managed for developmental dislocation of the hip. Methods. A retrospective cohort study of children, who have been hospitalized at our department between January 1998 and February 2007 with a developmental dislocation of the hip, was completed. Sixty-four patients satisfied the criteria for inclusion. Three groups according to age and treatment were identified. Group A and B included patients treated with closed or open reductions aged less than twelve months. Patients of group C were past walking age at the time of reduction and were treated by open reduction combined with concomitant pelvic and femoral osteotomies. The average duration of follow-up for all patients was 6.8 years. Logistic regression analysis was conducted to identify predictors for the development of osteonecrosis. Results. The overall rate of osteonecrosis in group A and B was 27.4% compared to 88.2% in patients of group C. After pooling of all data, no protective effect of the ossific nucleus of the femoral head on the development of osteonecrosis was found (p = 0.14). Additionally, an increase of surgical procedures in children of group C could not be demonstrated (p = 0.17). By using logistic regression analysis the type of reduction and secondary reconstructive procedure due to residual acetabular dysplasia could be identified as predictors for the development of osteonecrosis. Conclusions. Open reduction combined with concomitant osteotomies and secondary reconstructive interventions due to residual acetabular dysplasia increase the risk for osteonecrosis in the treatment of the developmental dislocated hip. Therefore, we advocate early reduction of the dislocated hip in the first year of life to avoid the need for concomitant osteotomies combined with open reduction. Level of Evidence. Prognostic study, level II-1 (retrospective study)

Aims

Minimally invasive fixation of pelvic fragility fractures is recommended to reduce pain and allow early mobilization. The purpose of this study was to evaluate the outcome of two different stabilization techniques in bilateral fragility fractures of the sacrum (BFFS).

Methods

A non-randomized, prospective study was carried out in a level 1 trauma centre. BFFS in 61 patients (mean age 80 years (SD 10); four male, 57 female) were treated surgically with bisegmental transsacral stablization (BTS; n = 41) versus spinopelvic fixation (SP; n = 20). Postoperative full weightbearing was allowed. The outcome was evaluated at two timepoints: discharge from inpatient treatment (TP1; Fitbit tracking, Zebris stance analysis), and ≥ six months (TP2; Fitbit tracking, Zebris analysis, based on modified Oswestry Disability Index (ODI), Majeed Score (MS), and the 12-Item Short Form Survey 12 (SF-12). Fracture healing was assessed by CT. The primary outcome parameter of functional recovery was the per-day step count; the secondary parameter was the subjective outcome assessed by questionnaires.

Introduction. Metal on metal hip resurfacing (MMHR) has been advocated for the younger patient for several reasons including for the preservation of bone stock and ease of revision to total hip replacement (THR), thus ‘buying an additional operation’ for the patient. This rationale however assumes a good functional outcome after the revision to a THR and that the results of the ‘revision primary’ will not be compromised by the resurfacing which preceded it. We present our data on a consecutive series of 68 revised MMHRs. Methods. Between September 1997 and September 2009, 927 consecutive patients underwent a hip resurfacing procedure performed by one of three senior surgeons at our institution. The Cormet resurfacing system was used for all patients. Sixty-eight of these patients had their resurfacing revised. Oxford hip score (OHS) obtained at a minimum of 12 months follow-up was used as the primary outcome measure. Results. Average age at time of index procedure was 51.9 (24 to 68) years. The MMHRs were revised an average of 49 (1 to 121) months after index procedure. At time of writing OHS post revision was 21.4 (range 12 to 48) at an average of 42 months post revision (range 16 to 111 months). Patients with a primary diagnosis of dysplasia were at an increased risk of revision RR 3.7 (1.9–7.1, p < 0.05).). No other primary diagnosis significantly increased risk of revision. Five patients underwent a second revision procedure. Discussion. We present the fuctional outcome scores of a large series of revised MMHRs. Despite MMHRs offering the advantage of preservation of bone stock we have found revision of MMHRs to THRs technically difficult. Our functional outcome scores in patients post revision were disappointing. We cannot support the concept that MMHR “buys patients another operation”

INTRODUCTION. Although simulation studies have shown superior wear properties of metal-on-metal articulations, increased concern exists regarding the excess in-vivo wear of a small number of Metal-on-Metal-Hip-Resurfacing (MoMHRA) implants. Serum ion levels of Chromium (Cr) and Cobalt (Co) are surrogate markers of wear. Risk factors associated with increased wear include female gender, small components, dysplasia, cup orientation outside safe zone and femoral head downsize during surgery with an associated decrease in Head-Neck-Ratio (HNR). However, these factors are interlinked. This study aims to identify the factors that are most important for subsequent wear of MoMHRA, by performing a multivariate analysis. METHODS. 206 patients (124M: 82F) with unilateral MoMHRA were included in this study. The average follow up was 3.3 years. All patients had Cr/Co levels measured at follow up. Inclination and anteversion of each cup were measured using EBRA. Cups were analysed as being within or outside the previously defined optimum-zone. HNR measurements were made from pre-operative (HNRpre) and post-operative (HNRpost) radiographs. The immediate changes in HNR (downsize/upsize of femoral head) as a result of the operation were expressed as:. HNRprepost=HNRpost–HNRpre. Multivariate linear regression modelling was used to explore the association between measures of ions with the following predictor variables (gender, age, diagnosis, femoral component size, orientation of the acetabular component, head/neck ratio and position of femoral stem). Analyses were carried out separately for each outcome (Cr and Co). Classification and Regression Tree (CART) models were fitted as a complimentary approach to regression modelling. RESULTS. Articular surface downsize followed by cup orientation within/outside optimum zone, followed by cup anteversion followed by gender were the strongest predictors of ion levels. A percentage decrease in HNRartpost, predicted an increase in Cr ion level by 5% (and 6% for Co). If the cup was within the optimum zone this was associated with decreased levels of Cr and Co ions. As acetabular component anteversion increased, levels of ions increased. Gender had a strong effect on ion levels. Adjusting for other variables, the effect of gender was attenuated due to a confounding effect of component size and the amount of femoral head downsize. Predictors identified as important in regression analyses were similar to those produced in the CART model, where the highest levels of ions were seen in patients with a percentage decrease in pre-operative HNR −11.3. DISCUSSION. This analysis shows that (surgical) factors, such as amount of femoral head downsize at operation and whether the cup was orientated within the optimum zone, explained the majority of the variability in ion levels in MoMHRA

Introduction. Chronic radial head dislocation in children after trauma is a serious condition. Often the dislocation is overseen initially and is a part of the Monteggia fracture complex with anterior bowing of the ulna. Typical complaints are pain, decreased ROM and cubitus valgus. Radial head dysplasia often occurs. The treatment of this condition is debated. Only few series of patients treated with open reduction and ulnar osteotomy exists with long-term follow up. We present a group of rare patients with long-time follow-up treated by only two surgeons through a period of 16 years. Materials and Methods. All 16 patients had anterior radial head dislocation (Bado type 1). Mean age at the time of traumatic dislocation was 6 years ranging from 2 to 9. We found a mean delay of 17 (range 1–83) months before open reduction and ulnar open wedge osteotomy. In 8 cases reconstruction of the annular ligament was performed and in 6 patients temporary transarticular fixation of the radial head with a k-wire was performed. Follow-up time was 8 (range 3–17) years postoperatively. Patients were investigated with bilateral x-ray, arthrosis status, congruency of the radiocapitellar joint, Oxford Elbow Score, force measurements and range of motion. Results. There were no major complications to surgery such as infection, nerve palsies or pseudarthrosis. Radiological results showed 9/16 with reduction of the radial head and with no arthrosis, 4/16 with arthrosis or subluxation, and 2/16 with a dislocated radial head. We found a significant correlation between radiological outcome and delay to ulnar osteotomy (p = 0.03). At follow up the mean Function score was 92 (SD 9), Social/psychological score 83 (SD 14) and Pain score was 88 (SD 15). None of the patients with fully reduced radial head had progressed in increased valgus deformity. In contrast, one of two patients with postoperative secondary dislocation of the radial head had an increase in carrying angle on 25 degrees. Typical clinical findings were a small but significant extension deficit and median loss of supination on 10 grades ranging from 0–90 (p = 0.008). Five patients had subsequent surgery, of which one had an excision of the radial head 8 years after primary surgery. Ligament reconstruction or transfixation of the radial head did not influence the radiological or clinical outcome. Discussion and Conclusion. Case reports of similar patients treated conservatively demonstrate high morbidity and therefore open reduction and ulnar osteotomy is justified given the good clinical longterm outcome in the present study. However, this study underlines the importance of minimising the delay between trauma and open reduction. If surgery is performed before 40 months after trauma good to fair longterm radiological results can be obtained. After 40 months there is a high risk of recurrent luxation of the radial head

Introduction. Osteoarthritis (OA) of the hip is an important cause of pain and morbidity. The mechanisms and pathogenesis of OA'sdevelopment remain unknown. Minor acetabular dysplasia and subtle variations in proximal femoral morphology are increasingly being recognized as factors that potentially compromise the joint biomechanically and lead to OA. Previous studies have shown that risk of hip OA increased as the femoral head to femoral neck ratio (HNR) decreased. Previous work has described the evolutionary change in inferior femoral neck trabecular density and geometry associated with upright stance, but no study has highlighted the evolutionary change in HNR. The aim of this study was to examine evolutionary evidence that the hominin bipedal stance has lead to alterations in HNR that would predispose humans to hip OA. Methods. A collaboration with The Natural History Museums of London, Oxford and the Department of Zoology, University of Oxford provided specimens from the Devonian, Jurassic, Cretaceous, Miocene, Palaeolithic and Pleistocene periods to modern day. Specimens included amphibious reptiles, dinosaurs, shrews, tupaiae, lemurs, African ground apes, Lucy (A. Afarensis), H. Erectus, H. Neaderthalis and humans. Species were grouped according to gait pattern; HAKF (hip and knee flexed), Arboreal (ability to stand with hip and knee joints extended) and hominin/bi-pedal. Imaging of specimens was performed using a 64 slice CT scanner. Three-dimensional skeletal geometries were segmented using MIMICS software. Anatomical measurements from bony landmarks were performed to describe changes in HNR, in the coronal plane of the different specimens over time using custom software. Measurements of HNR from the specimens were compared with HNR measurements made from AP pelvic radiographs of 119 normal subjects and 210 patients with known hip OA listed for hip arthroplasty. Results. Species from the HAKF group that ambulate via sprawling had the smallest HNR (1.10, SD: 0.09) (p<0.001). Species of the arboreal group (tree dwelling) had the biggest HNR (1.63, SD: 0.15) (p=0.006). The earliest bipedal species (1.41, SD: 0.04) had significantly bigger HNR (p=0.04) in comparison to the normal human subjects (1.33, SD: 0.08). Lower HNR was observed in the OA group (1.3, SD: 0.09). Discussion. The adoption of an upright stance during evolution has created an associated change in the femoral neck bone stock to adapt to the altered loading environment. These data would suggest that the HNR peaked in the Miocene period (10–15 million years ago). The trade-off between mobility and the bony density required to support gait has lead to a decreasing HNR throughout hominid evolution. Evolutionary theory would suggest that modern environmental pressures might pre-dispose future hominid evolution to an increased risk of hip OA

Introduction. Primary malign tumors and solitary metastatic lesions of the thoracic and thoracolumbar spine are indications for radical en bloc resections. Extracompartimental tumor infiltration makes the achievement of adequate oncological resection more difficult and requires an extension of the resection margins. We present a retrospective clinical study of patients that underwent chest wall resection in combination with vertebrectomy due to sarcomas and solitary metastases for assessing the clinical outcome especially focusing on onco-surgical results. Method. From 01/2002 to 01/2009 20 patients (female/male: 8/12; mean age: 52 (range of age: 27–76yrs)) underwent a combined en bloc resection of chest wall and vertebrectomy for solitary primary spinal sarcoma and metastatic lesions. The median follow-up was 20,5 (3–80) months. Histological analysis revealed 17 primary tumors and 3 solitary metastatic lesions. In the group of primary tumors 10 sarcomas, 1 giant cell tumor, 2 PNET, 1 histiocytoma, 1 aggressiv fibrous dysplasia, 1 pancoast tumor and 1 plasmocytoma were histologically documented. We included 1 rectal carcinoma, 1 breast cancer metastases and 1 renal cell carcinoma. All patients underwent a chestwall resection en bloc with multilevel (1/2/3/4 segments: n=4/6/6/4) hemi (n=7) or total vertebrectomy (n=13) with subsequent defect reconstruction. Reconstruction of the spinal defect following total resections was accomplished by combined dorsal stabilization and carbon cage interposition. The chest wall defects were closed with a goretex ® -patch. One patient also received a musculocutaneus latissimus dorsi flap. Results. The surgical margins were R0 in 19 (wide in 14, marginal in 5) and one R1 resection. Marginal/R1 resections were due to extracompartimental sarcoma invasion (spinal canal) and dural involvement. In these patients postoperative radiotherapy was performed. Surgical complications requiring revision occurred in 1 patient due to injury of the ductus thoracicus and persisting chylothorax. Temporary subileus or mild pneumonia appeared in 3 patients. No superficial/deep infection or neurological deficits (except those related to oncologically required dissection of thoracic nerve roots) were observed. At follow up 2 patients died due to the disease after 7,5 months. Local recurrences were seen in 3 patients at median 24 months (13–43). Pulmonary metastases necessitating polychemotherapy were seen in 7 patients after median 17 months (7–44). Conclusion. Despite the only midterm follow up, the combined en bloc resection of chest wall and multilevel en bloc spondylectomy/hemivertebrectomy is a challenging but safe and effective technique in order to achieve adequate margins and local control in selected with spinal sarcomas extending to the dorsolateral chest wall

Aims

Debate continues about whether it is better to use a cemented or uncemented hemiarthroplasty to treat a displaced intracapsular fracture of the hip. The aim of this study was to attempt to resolve this issue for contemporary prostheses.

Methods

A total of 400 patients with a displaced intracapsular fracture of the hip were randomized to receive either a cemented polished tapered stem hemiarthroplasty or an uncemented Furlong hydroxyapatite-coated hemiarthroplasty. Follow-up was conducted by a nurse blinded to the implant at set intervals for up to one year from surgery.

Aims

To evaluate the outcomes of cemented total hip arthroplasty (THA) following a fracture of the acetabulum, with evaluation of risk factors and comparison with a patient group with no history of fracture.

Patients and Methods

Between 1992 and 2016, 49 patients (33 male) with mean age of 57 years (25 to 87) underwent cemented THA at a mean of 6.5 years (0.1 to 25) following acetabular fracture. A total of 38 had undergone surgical fixation and 11 had been treated non-operatively; 13 patients died at a mean of 10.2 years after THA (0.6 to 19). Patients were assessed pre-operatively, at one year and at final follow-up (mean 9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant survivorship was assessed. An age and gender-matched cohort of THAs performed for non-traumatic osteoarthritis (OA) or avascular necrosis (AVN) (n = 98) were used to compare complications and patient-reported outcome measures (PROMs).

Aims

Periprosthetic femoral fractures (PFF) following total hip arthroplasty (THA) are devastating complications that are associated with functional limitations and increased overall mortality. Although cementless implants have been associated with an increased risk of PFF, the precise contribution of implant geometry and design on the risk of both intra-operative and post-operative PFF remains poorly investigated. A systematic review was performed to aggregate all of the PFF literature with specific attention to the femoral implant used.

Patients and Methods

A systematic search strategy of several journal databases and recent proceedings from the American Academy of Orthopaedic Surgeons was performed. Clinical articles were included for analysis if sufficient implant description was provided. All articles were reviewed by two reviewers. A review of fundamental investigations of implant load-to-failure was performed, with the intent of identifying similar conclusions from the clinical and fundamental literature.

Aims

The treatment of late presenting fractures of the lateral humeral condyle in children remains controversial.

Methods

We report on the outcome for 16 children who presented with a fracture of the lateral humeral epicondyle at a mean of 7.4 weeks (3 to 15.6) after injury and were treated surgically.
