Abstract
PURPOSE OF THE STUDY In clinical practice, it is generally accepted that hamstring tightness results in incomplete knee extension when the hip is in flexion and in smaller conventional and modified popliteal angles. Similarly, a difference between the conventional popliteal angle and the modified popliteal angle (popliteal differential) would be associated with a permanent deficit in knee extension. The purpose of this study was to determine whether these two hypothesis correlate with clinical findings. MATERIAL AND METHODS The series was composed of 35 walking cerebral palsy children, 16 girls and 19 boys, mean age 11+/-3.6 years with a pathological conventional popliteal angle. These children walked using the jump knee (n=24) or the crouch knee (n=11) pattern. Permanent hip flexion and the conventional and modified popliteal angles were noted. SPSS version 10.1.3 for Window was used to search for a correlation between the popliteal differential and the presence of permanent hip flexion using several values for the popliteal differential (5, 10, 15, 20, and 30 degrees ). Data were adjusted for age and gender. RESULTS The statistical analyses demonstrated a significant relationship between the presence of permanent hip flexion and a popliteal differential strictly less than 10 degrees and between the absence of permanent hip flexion and a popliteal angle greater or equal to 10 degrees . These statistically significant results, which demonstrated the opposite of what was expected, were independent of age and gender. DISCUSSION Our findings demonstrate that examination of the knee joint is indispensable but insufficient. The conventional popliteal angle is not a reliable indicator of hamstring tightness. The normal value of the modified popliteal angle has not been established so that it is impossible to determine what a pathological angle is. We do not know whether measurement of this angle is sufficient to establish indications for surgery. In the future, the development of muscle models coupled with gait analysis should enable more reliable prediction of outcome after surgery. At the present time, we recommend repeated physical examination using a standardized protocol, taking into consideration, several parameters including spasticity, selectivity and muscle force and to perform quantified gait analysis before scheduling hamstring lengthening surgery for walking cerebral palsy children.

Abstract
PURPOSE OF THE STUDY The appropriate treatment for unilateral slipping of the upper epiphysis of the femur is controversial. Prophylactic surgical treatment raises the risk of bilateralization. The procedure is often unnecessary as the natural history of epiphyseal slipping is often favorable when the displacement is minimal. We analyzed the complications of systematic prophylactic treatment in order to determine the optimal attitude. MATERIAL AND METHODS This was a retrospective series of 62 children who underwent surgery for unilateral slipping of the superior femoral epiphysis between 1996 and 2005. Prophylactic treatment of the healthy hip was instituted systematically. The complications were noted according to Paley. We searched for factors of risk of complications, studying the bone maturity indexes, the characteristic features of the healthy femur epiphysis and the surgical technique used. RESULTS There were seven complications, six following prophylactic treatment and one after material removal. The rate of complications reached 11.3%. Five of the complications were minor: two local infections with favorable outcome and three patients who complained of pain in the hip at mobilization, which had totally resolved at one year. One moderate complication was noted: spiral fracture of the upper femur starting from the screw head and treated with plate fixation. The outcome was favorable. There was one severe complication: osteoarthritis of the hip joint with septicemia on day 3. The outcome was unfavorable with necrosis of the femoral head, resection and use of a spacer. A total hip arthroplasty was performed at one year. DISCUSSION Complications were globally more frequent and more severe compared to series using prophylactic screwing. The major infection complication (osteoarthritis) observed in this series has not been reported elsewhere. There was probably a center effect since we recruited all of the most complex cases in our region. We were unable to identify any factor predictive of complications. There is apparently no clear choice between systematic prophylactic treatment and careful surveillance. Prophylactic treatment in selected patients might be the key to a successful preventive approach.

Abstract
We report the case of an 8-year-old boy who presented an osteoid osteoma of L5 associated with bilateral spondylolysis involving the same vertebra. Diagnostic bone scintigraphy is highly contributive in children presenting back pain. For us, it is the first intention exploration in patients with isthmic lysis seen on the plain x-ray. Symptomatic spondylolysis is the most frequent cause of back pain in children and is much more frequent than vertebral osteoid osteoma. The presence of isthmic lysis associated with focal uptake on the bone scintigraphy is highly suggestive of symptomatic spondylolysis. In this context, magnetic resonance imaging should be performed for both diagnostic purposes and prognostic assessment. The degree of bone and soft tissue edema in the present case was unusual for symptomatic spondylolysis. Complementary computed tomography finally established the diagnosis of osteoid osteoma of the posterior vertebral arch. To our knowledge, the association of osteoid osteoma with bilateral spondylolysis on the same vertebra has not been described elsewhere. In children, the diagnosis of symptomatic spondylolysis can only be established after ruling out other causes of back pain. The diagnosis of osteoid osteoma must be kept in mind.

Abstract
10035 Background: Ezrin is a cytoskeleton linker protein that is actively involved in the metastatic process of cancer cells. We have searched for a pronostic value of ezrin and some of its partners: a-smooth actin and CD44H in 37 patients with an osteosarcoma. Methods: Automate immunohistochemistry (IHC) with anti-ezrin, a-smooth actin and CD44H antibodies was performed in 37 biopsies before chemotherapy, 16 resected tumors of “poor” responders and 13 metastases. In addition the mRNA levels of ezrin of 13 frozen biopies and 4 metastases were evaluated by real time quantitative RT PCR. All results were correlated to the following clinical data: response to chemotherapy, onset of metastasis, event-free survival (EFS) and overall survival (OS). Results: Ezrin expression by IHC was found in 62% of 37 biopsies in the different histological subtypes especially chondroblastic osteosarcomas while chondrosarcomas were negative. A good correlation was found between positive or negative samples by IHC and mRNA levels. Ezrin expression was recorded in 84.5% of metastastic samples. The mean expression of ezrin was higher in metastases than biopsies (mean expression 38.1% versus 17.32%; p=0.024) but the onset of metastasis was not statistically correlated to ezrin positivity on biopsy (p = 0.183). In multivariate analysis, ezrin was an independent prognostic marker for EFS and OS with p<0.001 and p=0.003 respectively and a-smooth actin for OS only (p=0.024). No prognostic value was found for CD44H. Conclusions: We have shown that ezrin is expressed in the different subtypes of osteosarcomas especially chondroblastic osteosarcomas. Other studies are required to confirm that ezrin could be a useful tool for differential diagnosis with chondrosarcoma. Ezrin was an independent prognostic factor for event-free and overall survival rate in multivariate analysis and its partner a-smooth-actin was also an independent prognostic factor for overall survival only. These data confirm the role of ezrin signalling pathway for tumor dissemination in osteosarcomas in vivo. This also might be of interest for therapeutic strategy to select patient for dose intensification or to use new anticancer agents such as rapamycin which reduces experimental lung metastases through an ezrin-related pathway. No significant financial relationships to disclose.

Abstract
Rupture of the brachial artery associated with radial nerve palsy in a context of exostosis of the proximal humerus has not been described to date in the literature. Our patient was a fourteen-year-old girl with a history of violent pain occurring suddenly with no prodrome or triggering factor. The pain was localized at the level of the proximal left humerus. Physical examination revealed the presence of a hematoma and complete motor radial nerve palsy. The diagnosis was not confirmed by computed tomography with contrast injection but was confirmed by magnetic resonance imaging which eliminated malignant transformation of the exostosis. After checking the neurovascular bundles and evacuating the hematoma, treatment consisted in resection of the exostosis and arterial repair with an autologous venous graft. We discuss the diagnostic and therapeutic challenges which present vascular complications due to exostosis.

Abstract
PURPOSE OF THE STUDY The purpose of this study was to detail therapeutic indications for fractures of the intercondylar eminence of the tibia with little displacement and preservation of the posterior hinge (type II fracture in the Zarincznyj classification). MATERIAL AND METHODS We reviewed retrospectively a multicentric serie of type II fractures of the intercondylar eminence observed in children treated surgically. There were twenty patients, ten girls and ten boys, mean age 11.9 years (range 6-16). Imaging included plain x-rays of the knee (anteroposterior and lateral views) in all patients as well as computed tomography (5 patients) and magnetic resonance imaging (1 patient). Surgical treatment was performed in all cases, on average six days after trauma (range 0-25). A medial parapatellar arthrotomy was used in all cases. A non-resorbable thread was used for fixation associated with an anchor in the last four cases. Clinical and radiological assessment was reviewed at mean 3.7 years follow-up. RESULTS All children had resumed their sports activities at the same level as before the accident within 4.8 months on average. None of the children suffered from an unstable knee or functional impairment at last follow-up. The Lysholm score was 88.9 on average (range 70-100) at three months postoperative and 99.2 (range 89-100) at last follow-up. DISCUSSION There is currently agreement that non-displaced fractures of the anterior intercondylar eminence of the tibia should be treated orthopedically and that forms with displacement require surgery. Conversely, the type II fractures with an anterior gap but a preserved posterior hinge, the appropriate treatment remains a subject of debate. In our experience, surgery would appear to be preferable to orthopedic management. Surgery enables putting correct tension on the anterior crucicate ligament and limits the risk of residual laxity which, even though rarely associated with instability, could in the long-term lead to osteoathritic degradation or meniscal damage. CONCLUSION Surgical treatment of fractures of the intercondylar eminence of the tibia with little displacement and preservation of the posterior hinge provides satisfactory results and the best guarantee of long-term stability.

Abstract
OBJECTIVE Compare the irradiation delivered in conventional radiography and digital radiography by image intensifier during a scoliosis workup. PATIENTS AND METHODS Our prospective randomized study included 105 patients, all of whom were identified according to sociodemographic parameters as well as criteria evaluating the quality of the full front spinal x-ray at PA incidence. The entry dose at the scapula and the exit dose in interorbital, thyroid, mammary, and hypogastric projection was measured by thermoluminescent dosimeters. RESULTS The results of 71 girls and 28 boys, aged a mean 13.8 years with a mean weight of 47 kg were analyzed. At equal image quality, the entry dose was not significantly different between the two techniques; the mean exit dose reduction was 64% during digital acquisition. This reduction involved the interorbital (162%), mammary (43%), and thyroid (309%) regions. However, this system is more irradiating in the hypogastric region (34%). CONCLUSION The dosimetric evaluation of the different imaging techniques used to explore the entirety of the spine should be part of radiologists' quality standard used to document their work and their choices.

Abstract
We report two cases of fasciitis with necrotizing hypodermitis of the foot and arm which complicated varicella in immunocompetent children given nonsteroidal anti-inflammatory drugs. The skin barrier and immune function are weakened by the varicella zoster virus. Exposure to nonsteroidal anti-inflammatory drugs further favors necrotizing cutaneous infections caused by group A beta hemolytic streptococci. MRI can confirm the presence of superficial aponevrosis necrosis defining necrotizing fasciitis but should not retard surgical management which is always indicated for necrotizing fasciitis and sometimes for necrotizing dermo-hypodermitis.

Abstract
During hominin evolution, an increase in the femoral bicondylar angle was the initial change that led to selection for protuberance of the lateral trochlear lip and the elliptical profile of the lateral condyle. No correlation is found during ontogeny between the degree of femoral obliquity and of the prominence of the lateral trochlear lip. Might there be a relationship with the elliptical profile of the lateral condyle? On intact femoral diaphyses of juvenile humans and great apes, we compared the anteroposterior length of the lateral and medial sides of the distal metaphysis. The two diaphyseal pillars remain equal during postnatal growth in great apes, while the growth of the lateral pillar far exceeds that of the medial pillar in humans. Increase in bicondylar angle is correlated with disproportionate anteroposterior lengthening of the lateral pillar. The increased anteroposterior length of the lateral side of the metaphysis would contribute to increasing the radius of the curvature of the lateral condyle, but not to the projection of the lateral trochlear lip. The similar neonatal and adult femoro-patellar joint shape in humans prompted an assessment of the similarity during growth of the entire neonatal and adult epiphyses. We showed that the entire epiphysis undergoes drastic changes in proportions during postnatal growth. Finally, we emphasize the need to distinguish the cartilaginous phenotype and the ossified phenotype of the distal femoral epiphysis (and of any epiphysis) during postnatal growth. This crucial distinction applies to most postcranial bones, for they almost all develop following the process of endochondral ossification.

Abstract
PURPOSE OF THE STUDY Resection of malignant tumors of the proximal humerus often requires dissection of the rotator cuffs and the deltoid muscle. There is no consensus on the ideal method for shoulder reconstruction. We report the functional outcome in a homogeneous series of eight patients treated by arthrodesis using a vascularized free fibular flap. MATERIAL AND METHODS Eight patients were included in this study. All had an aggressive tumor of the upper humerus. Tumor resection was associated with a rotator cuff and deltoid muscle resection in all patients. All patients then underwent shoulder arthrodesis using a free vascularized fibular flap fixed with a plate. Clinical and radiological evaluation was available for six patients at mean 28 months. The Musculoskeletal Tumor Society function score was used to assess overall function of the upper limb. The cosmetic outcome and radiographic bone healing as well as hypertrophy of the fibular graft were noted. RESULTS Active abduction and active flexion were 82 degrees on average. All patients could bring their hand to the mouth. Circumduction was possible but limited in amplitude. The mean function score was 26.5/30 with an excellent functional outcome in all patients. The cosmetic outcome was considered poor by all patients. Radiographically, bone healing was achieved at last follow-up in all patients but there was one case of failed fusion between the fibular graft and the scapula which required secondary iliac grafting. Mean fibular graft hypertrophy was 32.8% at last follow-up. DISCUSSION AND CONCLUSION Two reconstruction methods have been described for patients who require tumor resection of the upper humerus: reconstruction with preservation of glenohumeral joint function and shoulder arthrodesis. Many techniques have been described for each method. It is however difficult to compare the different series reported in the literature because rotator cuff and deltoid muscle resection was not systematically performed and reconstruction methods varied between patients. An analysis of the literature shows that preservation of motion of the scapular glenoid joint can give good functional results when the rotator cuff and deltoid muscle can be preserved. If they cannot, results favor shoulder arthrodesis which provides the patient with very satisfactory upper limb function. Use of a vascularized fibular flap has provided very good arthrodesis results. The patient must however be informed of the probable poor final cosmetic result.

Abstract
PURPOSE OF THE STUDY The natural history of congenital scoliosis or kypho-scoliosis resulting from a hemivertebra is well documented. The spinal deformation generally worsens in children with a free or semi-segmented hemivertebra situated in the thoraco-lumbar, lumbar or lumbosacral region. MATERIAL AND METHODS From 1982 to 1997, fifteen pediatric patients with 15 hemivertebrae causing progressive scoliosis or kypho-scolisosis underwent hemivertebral resection via a double posterior and anterior approach associated with convex fusion. Mean age at surgery was 4.4 years. The fifteen patients were reviewed at bone maturity (Risser 4 or 5) to assess outcome. RESULTS Genitourinary tract anomalies were associated in five of the 15 patients and intrathecal anomalies in two. Mean follow-up was 12.1 years. Segmental scoliosis was 30.2 degrees preoperatively, 12.3 degrees postoperatively and 8.9 degrees at last follow-up. The values for total scoliosis were 30.5 degrees, 12.3 degrees and 12.6 degrees respectively. This was a 70.5% improvement at last follow-up for segmental scoliosis and 58.7% for total scoliosis. The real trunk imbalance improved from 31% preoperatively to 9% at last follow-up. All these differences were significant. DISCUSSION The main objective of surgical treatment for congenital scoliosis due to hemivertebra is to prevent the development of severe deformation which would necessitate a dangerous and difficult procedure to achieve correction. Resection of the hemivertebra via a double approach is the ideal method for early correction. The procedure not only corrects the spinal deformation but also prevents later deterioration. Correction should be performed as early as possible. The result is sustained over time if there is no other associated spinal anomaly. The procedure is safe and the technique well controlled in experimented hands. Patients need to wear a corset for only six months after resection of the hemivertebra.

P/A is defined as the ratio between P, the distance between the posterior vertebral wall and the remnant of the posterior arch, over A, the distance between the anterior wall and the posterior vertebral wall, measured on the lateral view of the spine in the most dysplastic vertebra before one year of age. MATERIAL AND METHODS The files of 163 children were reviewed. The value of the P/A ratio was measured on lateral views of the spine obtained before the age of one year. The bone level on the anteroposterior film was also noted. The presence or absence of kyphosis was determined from the lateral views obtained at ten years of age. Paired variable analysis was used to compare the mean differences in P/A at one year and at ten years in 31 patients with a bone level of L1 or higher. The exact Fisher test was used to determine the difference in the kyphosis distributions in patients with a bone level of L1 or higher between those with P/A < or = 1/2 and the others. In addition, the specificity, sensitivity, and positive predictive value of a positive test (bone level L1 or higher and P/A < or = 1/2) for development of kyphosis were calculated. Results There was no statistically significant difference in the P/A mean value before the age of one year and after ten years. The distribution of patients with kyphosis was different between patients with a bone level of L1 or higher and P/A < /2 and the other patients (p < 0.01). Considering having a bone level of L1 or higher and a P/A < or = 1/2 as a prognostic test, the specificity was 100%, the sensitivity 87.56%, and the positive predictive value 100%. Many patients with spina bifida will develop kyphosis in the course of life. This spinal deformation raises many specific problems for patient management. Use of a radiological index as presented here allows early detection of patients at risk and can also predict which patients will remain free of deformation. This allows a selection of patients who can benefit most from more regular surveillance of the spinal static and avoid unnecessary radiographic examinations in others.

Abstract
We report the case of a girl presenting with an unusual form of multiple joint fusion. Skeletal abnormalities consisted of radioulnar synostosis and vertebral fusions without any carpal, digital or tarsal involvement, and broad ribs and clavicles. Spinal X-rays were available from age 4 to 21, demonstrating that the spinal involvement was progressive and led to a complete anterior and lateral fusion of vertebrae. A complete sequencing of the NOGGIN gene failed to find any mutation. In addition, this girl was carrier of an apparently balanced reciprocal translocation t(10;20)(p11;p13). We investigated the role of the BMP2A gene as a potential candidate gene. Fluorescence in situ hybridization with YAC probes from chromosome 20 showed that the BMP2A gene was not disrupted by the translocation breakpoint.

Abstract
Chronic granulomatous disease is a rare immune disease related to an anomaly in phagocytes NADPH oxidase. The characteristic clinical feature is early recurrent and sometimes serious infection. We report the case of a 22-month-old child who developed multifocal osteomyelitis, an unusual inaugural manifestation of chronic granulomatous disease. Septic chronic granulomatous disease is an uncommon differential diagnosis in children who develop recurrent infections. Diagnosis is established with specific blood tests: reduction of tetrazolium nitroblue, chemoluminescence test, molecular analysis. Therapeutic management must be undertaken as early as possible in order to preserve the long-term prognosis. No curative treatment is currently available. Aggressive treatment of each infectious focus with an adapted antibiotic regimen and in certain cases surgical debridement is required in addition to long-term antibiotic prophylaxis.

Abstract
PURPOSE OF THE STUDY We performed a biometric analysis of the femoral trochlea in the fetus and compared our findings with those observed in adults in order to search for correlations with other biometric parameters of the femur. MATERIAL AND METHOD Twenty-two fetuses (44 knees) conserved in formol and free of known orthopedic disease were studied. Fetal age ranged from 26 to 40 weeks. After anatomic dissection, digitalized images were used to obtain angle measurements with a dedicated software. Measurements made on the distal epiphyseal view were: anteroposterior dimension of the condyles, medial and lateral protrusion of the trochlear borders, difference in condyle height, length of the trochleal borders, alpha angle of the trochlear groove, trochlear slope. Measurements made on the AP femoral view were: femoral anteversion, length of the femoral neck, neck-shaft angle. Spearman's test was used to search for correlations. Results were compared with measurements obtained under the same conditions in a series of 32 adult knees published by Wanner. RESULTS The trochlear alpha angle was 148 degrees (coefficient of variation 4%). The angle was greater than 150 degrees for 18 trochleae. The lateral border of the trochela was higher than the medial border in 37 of the 44 knees. There was no correlation with age and gender. Femoral anteversion was 27.01 degrees, with a high coefficient of variation (46%), and no correlation with the trochlear alpha angle. Comparison with measurements made on the adult knees revealed no significant difference. DISCUSSION This is the first report of statistically significant biometric data of the fetal trochlea. The morphology of the lower femur observed during the third trimester of fetal live is the same as observed in adults. Morphological changes in the proximal femur occurring during growth do not appear to modify the morphology of the distal femur. The asymmetrical ingression of the patella into the trochlea, characteristic of modern man, is considered to result from bipedalism. Our study would suggest that the anatomic characteristics of the trochlea could have been integrated into the genoma during the course of evolution. This would be in favor of a genetic origin of trochlear dysplasia.
