Introduction: Little data exist on the efficacy of enhanced recovery after surgery (ERAS) protocols in patients undergoing posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS)., Hypothesis: ERAS reduces hospital costs (HC) and length of stay (LOS) without increasing pain or complications., Materials and Methods: This was a retrospective comparative medical and economic study of 2 cohorts of patients who underwent PSF for AIS: a prospective group who underwent surgery with an ERAS protocol without a specially assigned care coordinator from 2020 to 2021 (n=30) and a retrospective group (control) who received standard care from 2017 to 2018 (n=30). The key amendments to the ERAS protocol were reduced preoperative investigations, opioid-sparing analgesia, ambulation starting on postoperative day (POD) 1, early resumption of oral diet, and early transition to oral analgesics. Moreover, an intensive care unit (ICU) stay, surgical drainage, and the postoperative CT scan were no longer routine. The discharge criteria were the same for both groups: normal bowel function, independent walking, pain Visual Analog Scale (VAS)<3 without strong opioids, and no signs of complications. The endpoints were: decreased HC (calculated by subtracting the costs of hospital days and complementary exams that were not carried out) and LOS, complications, and postoperative pain according to the VAS on POD 1, POD 3, and discharge. All means were reported with the standard deviation., Results: The mean age of patients undergoing surgery (14.5±1.7 years), sex ratio, curve type according to the Lenke classification, mean Cobb angle (54±12°), and the number of instrumented vertebrae (9±2) were similar in both groups (p>0.5). The HC decreased on average by 3029€ per patient. The mean LOS was 5±0.9 days in the ERAS group versus 6.5±0.6 days in the control group (p<0.001). The VAS scores on POD 1 and POD 3 were lower in the ERAS group. One postoperative complication was noted in each group., Conclusion: Implementing an ERAS protocol without a specifically assigned care coordinator for patients with AIS undergoing PSF significantly decreased HC, LOS, and early postoperative pain., Level of Evidence: III; retrospective comparative study., (Copyright © 2023 Elsevier Masson SAS.

Background: Congenital absence of the quadriceps is an extremely rare condition whose management is not standardised. The objective of this study was to describe the clinical presentation, treatments, and outcomes of a multicentre cohort., Hypothesis: Classification of the type of abnormality at birth helps to guide management decisions., Methods: Fifteen patients (19 knees) were included retrospectively in this multicentre study. Data on joint range-of-motion and management were analysed. We divided the patients into three groups based on whether they had continuous hypoplasia (involving the entire quadriceps), discontinuous hypoplasia (hypoplasia of some of the muscle groups or aplasia of the distal third of the quadriceps), or aplasia (complete absence of the quadriceps with replacement by fat)., Result: Physiotherapy was provided initially to all patients. The main treatment in the 6 patients with continuous hypoplasia was posterior release and biceps femoris lengthening. At last follow-up all 6 patients were able to walk unaided, although 4 of them had persistent knee extension lag. Quadriceps reconstruction and osteotomy to correct knee recurvatum deformity were performed in most of the 11 patients with discontinuous hypoplasia. Among them, 10 were able to walk unaided at last follow-up, and 5 had knee extension lag. The 2 patients with aplasia required knee arthrodesis after multiple surgical procedures. Both were able to walk., Discussion: Depending on the classification of the abnormality at birth, different surgical procedures should be considered. Surgery should only be performed after non-operative treatment. The treatment goal is to obtain a normal mechanical axis of the limb with the knee in extension and no extension lag, in order to enable walking., Level of Evidence: IV, retrospective observational study., (Copyright © 2022 Elsevier Masson SAS.

Introduction: In children treated for idiopathic equinovarus clubfoot (EVCF), the relation between morphologic defects on clinical examination and standard X-ray on the one hand and functional abnormalities on the other is difficult to objectify. The aim of the present study was to demonstrate the feasibility of combined 3D analysis of the foot and lower limb based on biplanar EOS radiographs and gait analysis. The study hypothesis was that this provides better understanding of abnormalities in form and function., Methods: Ten children with unilateral EVCF and "very good" clinical results were included. They underwent gait analysis on the Rizzoli Institute multisegment foot model. Kinematic data were collected for the hip, knee, ankle and foot (hindfoot/midfoot, midfoot/forefoot and hindfoot/forefoot). Biplanar EOS radiographs were taken to determine anatomic landmarks and radiological parameters., Results: Complete acquisition time was around 2hours per patient. No significant differences were found between EVCF and healthy feet except for calcaneal incidence, tibiocalcaneal angle and hindfoot/midfoot and hindfoot/forefoot inversion., Discussion: The feasibility of the combined analysis was confirmed. There were no differences in range of motion, moment or power between EVCF and healthy feet in this series of patients with very good results. The functional results are related to radiological results within the normal range. The protocol provided anatomic and kinematic reference data. A larger-scale study could more objectively assess the contribution of EOS radiography using optoelectronic markers., Level of Evidence: II, low-power prospective study., (Copyright © 2019 Elsevier Masson SAS.

Congenital pathologies of the forefoot encompass two broad entities with vastly different treatments and prognosis: malformations, which occur during the embryonic period and cause anatomical defects, and deformations, which occur during the fetal period on a foot that is configured normally. These deformities are more easily cured when they occur later during the fetal period. When the anomaly is bilateral, a genetic origin must be considered. There are two main entities under the term "deformity": metatarsus adductus and skewfoot (aka "Z"-foot or serpentine foot). Within malformations are brachydactyly (transverse defects), longitudinal defects, syndactyly, polydactyly, clinodactyly and macrodactyly. Among other forefoot abnormalities are hallux valgus, which rarely presents in congenital form, and for which conservative treatment is sometimes sufficient. Also in this group are sequelae of amniotic band constriction, forefoot anomalies secondary to the treatment of congenital pathologies (talipes equinovarus and congenital vertical talus) and nail-related pathologies (ingrown toe nail and incorrect nail position)., (Copyright © 2019 Elsevier Masson SAS.

Introduction: Restoring a degree of kyphosis consistent with good sagittal alignment of the spine is a key concern when performing surgery to correct adolescent idiopathic scoliosis (AIS). The objective of this study was to assess the preliminary outcomes of posterior fusion for AIS using patient-specific rods that were pre-contoured based on pelvic incidence. The primary evaluation criterion was thoracic kyphosis at last follow-up., Hypothesis: The use of pre-bent patient-specific rods has a favourable effect on thoracic kyphosis at last follow-up., Material and Methods: A total of 37 patients with AIS, including 17 with hypokyphosis, managed with patient-specific rods were included in a prospective study. The rod contouring angles were based on predefined pelvic incidence criteria (25° to 40° for the rod on the convex side and the same value plus 10° for the rod on the concave side). Thoracic kyphosis was assessed before surgery and at last follow-up, after 12-36 months (mean, 19 months). Student's t test was applied to compare means. Multivariate linear regression analysis was performed., Results: At last follow-up, the mean increase in kyphosis was 14° and was comparable to the planned increase (mean difference=0, p=0.85). Factors associated with kyphosis at last follow-up were the concave rod contouring angle and the pre-operative kyphotic angle of the thoracic segment to be instrumented (p<0.05). Mean differences between kyphosis of the instrumented thoracic segment at last follow-up and target kyphosis were -5° in the subgroup with hypokyphosis (<20°) before surgery and +4° in the subgroup with normal kyphosis before surgery., Conclusion: With patient-specific rods, kyphosis at last follow-up was close to the target value. Predictors of kyphosis at last follow-up were the concave rod contouring angle and pre-operative kyphotic angle of the thoracic segment to be instrumented. Over-contouring of the concave rod seems necessary in patients with preoperative hypokyphosis but not in patients with normal kyphosis., Level of Evidence: III, prospective non-comparative study., (Copyright © 2019 Elsevier Masson SAS.

Background: Studies have established that Blount's method is reliable for treating extension supracondylar fractures (SCFs) in paediatric patients. Reduction in the emergency room (ER) under procedural sedation followed by orthopaedic treatment is increasingly used for many fracture types. The primary objective of this study was to determine whether SCF reduction in the ER was feasible, by determining the failure rate. The secondary objective was to identify causes of failure with the goal of improving patient selection to reduction in the ER., Hypothesis: Gartland II and III SCFs (Lagrange-Rigault grades 2-4) can be treated in the emergency room under fluoroscopic guidance and with procedural sedation., Material and Methods: A retrospective study was conducted in 128 paediatric patients who underwent ER reduction of an SCF in 2014-2015. Mean age was 5.6 years. Reduction was performed either by an orthopaedic surgery resident or by a specially trained emergency physician., Results: Of the 128 SCFs, 101 (79%) were Gartland II and 27 Gartland III. In the Lagrange-Rigault classification, 55 (43%) fractures were grade 2, 59 (46%) were grade 3, and 14 (11%) were grade 4. The arm was immobilised using the cuff-and-collar method described by Blount for 4 weeks. All 128 fractures healed without delay. Blount's method alone was effective in 112 (87.5%) patients. Of the 16 other patients, 15 (Lagrange-Rigault 3, n=14; and 4, n=1) had an unstable fracture after ER reduction and were managed by reduction and internal fixation in the operating room. The remaining patient (0.5%) experienced secondary displacement requiring revision surgery in the operating room., Conclusion: SCFs grades 2 to 4 in the Lagrange-Rigault classification (Gartland II and III) can be treated in the ER by specially trained physicians. Lagrange-Rigault grade 3/Gartland III SCFs are more likely to require subsequent internal fixation but do not contraindicate reduction in the ER., Level of Evidence: IV, retrospective study., (Copyright © 2018 Elsevier Masson SAS.

Background: Cobalt-chrome (CoCr) and the titanium alloy TA6V (Ti) are the materials most widely used for spinal instrumentations in patients with adolescent idiopathic scoliosis (AIS). The objective of this work was to compare the effectiveness of CoCr and Ti rods in terms of coronal and sagittal correction by pedicle screw constructs in patients with AIS., Hypothesis: Correction is similar with CoCr and Ti rods in patients with AIS., Material and Method: A retrospective single surgeon study was conducted in patients with AIS managed using pedicle screw posterior spinal fusion with high implant density and reduction by postero-medial translation. Follow-up was more than 2 years in all patients. Patients were divided into two groups based on whether the rods used were made of CoCr (n=30) or Ti (n=33). The groups were identical for age, Risser classification, follow-up duration, type of curve, and implant density. Coronal and sagittal parameters on standing full-spine radiographs were analysed using graphics software before surgery then 1 month after surgery and at last follow-up. Quantitative data were compared by applying Student's t test., Results: The percentage of main curve correction at last follow-up was the same in the two groups (76%/75%) (p=0.7). Gains in thoracic kyphosis (12°/13°) and lumbar lordosis (8°/10°) were not significantly different between groups. At last follow-up, 3 patients had proximal junctional kyphosis, 1 in the CoCr group and 2 in the Ti group (p=0.6)., Conclusion: For posterior spinal fusion to treat AIS, with a high density of pedicle screws, correction by translation, and 6 mm rods, CoCr rods and Ti rods produce the same amount of coronal and sagittal correction., Level of Evidence: IV, comparative retrospective study with no control group., (Copyright © 2018 Elsevier Masson SAS.

Background: The physical examination and weight-bearing radiography are the two main available methods for assessing the feet and lower limbs. The anatomy and function of these two structures interact with each other. These two assessment methods are affected by subjectivity and projection bias. Low-dose biplanar radiography (LDBR) is now a promising alternative for evaluating the lower limbs in children. At present, however, the foot cannot be assessed using LDBR. The objective of this study was to work towards developing a new method for 3D radiographic analysis of the paediatric foot during weight-bearing, first by determining the reproducibility of landmarks defined by LDBR then by reporting the values of the calculated radiographic parameters., Hypothesis: A new radiographic method based on LDBR can be used to obtain a 3D evaluation of the foot in paediatric patients., Patients and Methods: Two biplanar radiographs in perpendicular planes were obtained simultaneously in a standardised position using the EOS system (EOS ® Imaging, Paris, France) in each of 10 healthy children. To assess measurement uncertainty, two observers performed 3D reconstructions of each of the 10 feet three times (60 reconstructions). The standard error of reproducibility of the anatomic landmarks and clinical parameters was computed. Measurement uncertainty was then estimated based on the 95% confidence interval (95%CI). To obtain reference values, the mean±SD of each variable was computed after checking that the data were normally distributed., Results: Reproducibility was high for the anatomical landmarks of interest, calcaneal pitch angle, tibio-calcaneal angle on the lateral view, and first metatarsal pitch angle (95%CI<5%). The values of these angles in the study population are reported., Discussion and Conclusion: The data reported here pave the way towards developing new parameters for describing 3D foot morphology and for simultaneously assessing the lower limb and foot in the standing position., Level of Evidence: I., (Copyright © 2018 Elsevier Masson SAS.

Background: Lower-limb alignment in children is classically assessed clinically or based on conventional radiography, which is associated with projection bias. Low-dose biplanar radiography was described recently as an alternative to conventional imaging. The primary objective of this study was to assess the reliability of length and angle values inferred from 3D reconstructions in children seen in everyday practice. The secondary objective was to obtain reference values for goniometry parameters in children., Hypothesis: 3D reconstructions can be used to assess the lower limbs in children., Material and Methods: The paediatric reliability study was done in 18 volunteers who were divided into three groups based on whether they were typically developing (TD) children, had skeletal development abnormalities, or had cerebral palsy. The reference data were obtained in 129 TD children. Each study participant underwent biplanar radiography with 3D reconstruction performed by experts and radiology technicians. Goniometry parameters were computed automatically. Reproducibility was assessed based on the intra-class coefficient (ICC) and the ISO 5725 standard (standard deviation of reproducibility, SDR)., Results: For length parameters, the ICCs ranged from 0.94 to 1.00 and the SDR from 2.1 to 3.5mm. For angle parameters, the ICC and SDR ranges were 0.60-0.95 and 0.9°-4.6°, respectively. No significant differences were found across experts or radiology technicians. Age-specific reference data are reported., Discussion: These findings confirm the reliability of low-dose biplanar radiography for assessing lower-limb parameters in children seen in clinical practice. In addition, the study provides reference data for commonly measured parameters., Level of Evidence: IV., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Background: Supracondylar fractures of the elbow with major displacement are usually treated by surgical pinning and less often non-operatively as described by Blount. The objective of this study was to assess the clinical and radiological outcomes of Gartland type III supracondylar fractures treated at least 3 years earlier using Blount's method., Hypothesis: Blount's method produces good outcomes after more than 3 years when used to treat Gartland type III supracondylar fractures of the humerus., Methods: A single-centre retrospective study was done in paediatric patients who were seen within 24hours after sustaining a Gartland type III supracondylar fracture then re-evaluated at least 36 months after treatment. Closed reduction was performed either in the operating room under general anaesthesia or in the radiology suite under procedural sedation. The upper limb was then immobilised for 4 weeks using the cuff-and-collar method described by Blount (mean elbow flexion, 134°). The child was evaluated and radiographs obtained at the outpatient clinic on days 7 and 14. Functional outcomes were assessed using the 1962 SoFCOT criteria and Flynn's criteria and the radiological outcome using Baumann's angle, the humero-condylar angle, and distal fragment rotation. From 2009 to 2013, 22 patients met the inclusion criteria. Mean follow-up was 57 months., Results: Clinical outcomes assessed using the 1962 SoFCOT criteria were very good in 15 patients and good in the remaining 7 patients. The rate of satisfactory outcomes according to Flynn's criteria was 100%. At last follow-up, mean Baumann's angle was 68°, mean humerocondylar angle was 42°, and 2 patients had residual rotation of the distal fragment., Conclusion: This work confirms the effectiveness of Blount's method for treating Gartland type III supracondylar fractures. We advocate routine first-line treatment of these fractures using Blount's method in the absence of vascular compromise and instability., Level of Evidence: IV, retrospective study., (Copyright © 2017 Elsevier Masson SAS.

Background: The initial treatment of congenital idiopathic clubfoot (CIC) is nonoperative. Either the French physiotherapy method or the Ponseti casting method may be used. Whether either method is superior over the other remains unclear. However, the method used initially is not the only determinant of the final outcome., Objective: The primary objective was to identify determinants of the final outcome as evaluated based on the need for surgical treatment and on the Ghanem-Seringe score., Hypothesis: Factors associated with the final outcome can be identified., Methods: Between 2004 and 2011, 100 CICs in 79 patients were treated in two centres, 47 using the French method and 53 the Ponseti method. The Dimeglio grade was determined at baseline and the Ghanem-Seringe score at last follow-up. Surgical procedures (if any), splinting duration, and rehabilitation therapy duration were recorded. The two groups showed no statistically significant differences for Dimeglio grade distribution, time from birth to treatment initiation, or mean follow-up., Results: Factors significantly associated with a poor outcome by univariate analysis were use of the Ponseti method (P=0.0027), older age at last follow-up (P=3×10 -4 ), initial Dimeglio grade (P=7×10 -5 ), and need for surgery (P=10 -5 ); no significant effect was found for splinting duration, rehabilitation duration, bilateral involvement, or antenatal diagnosis. By multivariate analysis, factors independently associated with a poor prognosis were older age at last follow-up, Dimeglio grade, and need for surgery., Conclusion: This study confirms the major prognostic significance of initial severity (Dimeglio grade) on the final outcome. The data do not firmly establish that one method is superior over the other. Nevertheless, the need for percutaneous Achilles tenotomy with the Ponseti method leads us to prefer the French physiotherapy method., Level of Evidence: IV, retrospective study., (Copyright © 2016 Elsevier Masson SAS.

Introduction: Neurologic pes cavus is a progressive deformity that is difficult to treat during growth. The present study reports results of non-operative management, based on the pathophysiology of the deformity, by untwisting nocturnal splint, preceded in some cases by untwisting walking cast. The objective was to assess efficacy and impact on indications for surgery., Method: Twenty-three children (35 feet) were included. All had neurologic cavovarus foot, which was progressive in 24 feet (69%) (Charcot-Marie-Tooth disease). Mean age at initiation of treatment was 8.8 years. In 13 feet (38%), treatment began with a untwisting walking cast and in 22 (62%) began directly with the splint., Results: Mean follow-up was 4.5 years. Fifteen feet showed very good and 8 good clinical results (65%); 9 children (12 feet) had moderate or poor results, requiring renewed treatment in 11 feet at a mean 4.5 years after initiation of non-operative treatment. Thirteen patients (56.5%, 21 feet) had reached end of growth by last follow-up; 10 of these feet (48%) had good or very good results without surgery. No triple arthrodeses were required. Factors weighing against good outcome comprised young age at treatment initiation and poor compliance with the splint. Primary deformity severity did not affect outcome., Conclusion: The present study demonstrated efficacy for non-operative treatment of childhood neurologic cavovarus foot. Surgery was either avoided (in half of the cases followed up to end of growth) or delayed by a mean 4.5 years, allowing a single procedure before end of growth. We recommend initiating non-operative treatment of childhood cavovarus foot, associating untwisting walking cast and untwisting nocturnal splint, as soon as clinical progression is detected and/or Méary angle on lateral X-ray with block reaches 15°., Level of Evidence: IV., (Copyright © 2016 Elsevier Masson SAS.

Introduction: The too-long anterior process (TLAP) can be responsible for ankle pain or repeated sprains in children or adolescents. The objective of this study was to assess the results of TLAP surgical treatment and to analyze influencing factors in case of this surgery's failure., Material and Methods: Retrospective single-center study conducted from 2009 to 2012 including all patients under 18 years of age for a TLAP with follow-up equal to or longer than 1 year. The results of surgical treatment were assessed using the AOFAS score. Failure was defined as no significant improvement in the AOFAS score at the last follow-up., Hypothesis: Predictive factors of the result of surgical treatment for TLAP can be identified., Results: At the mean follow-up of 2.5 years, 35 patients (43 feet) fulfilled the inclusion criteria. Thirteen feet (30%) presented surgical failure. According to the AOFAS score, the results were excellent in 30 feet (70%), good in four (9%), fair in five (12%), and poor in four (9%). Surgical failure was influenced by the patient's age at the onset of symptoms and at the time of surgery, the degree of functional limitation, the duration of symptoms before surgery, the number of sprains, and gender (P<0.05)., Conclusion: Firstly, in this pediatric population with its high functional demand, the overall rate of failure of TLAP surgery was 30%. Secondly, the factors associated with failure demonstrated made it possible to identify the ideal patient for this surgery: male, with symptom onset between 7 and 10 years of age, who had experienced fewer than 15 sprains, and undergone surgery in the 3 years following the beginning of symptoms., Level of Evidence: IV., (Copyright © 2016 Elsevier Masson SAS.

Introduction: Congenital dislocation of the knee (CDK) is rare, and clinical semiology at birth is not always suitably analyzed. Existing classifications fail to guide treatment. The aim of the present study was to develop a CDK classification for the neonatal period., Hypothesis: A classification based on neonatal severity of clinical signs is easy to implement on simple criteria., Material and Methods: Fifty-one CDKs (40 patients) seen neonatally were included. Three types could be distinguished in terms of reduction and stability: type I, easily reducible CDK, with reduction snap when the femoral condyles pass in flexion, remaining stable in flexion; type II, "recalcitrant" dislocation, reducible by posteroanterior "piston" but unstable, with iterative dislocation once posteroanterior pressure on the condyles is relaxed; and type III, irreducible. The number of anterior skin grooves, global range of motion, flexion deficit and reduction stability were noted for each type., Results: Mean age at first consultation was 5.6 days (range: 0-30). CDK was type I, II and III in respectively 28, 16 and 7 cases. Number of skin grooves, flexion and baseline range of motion were greater in type I than types II and III., Conclusion: The present neonatal clinical classification is original, logical and simple. It may be useful for prognosis and guiding treatment., Level of Evidence: IV, single-center retrospective series., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Introduction: An original classification of congenital dislocation of the knee (CDK) was drawn up, based on neonatal semiology. The objective of the present study was to assess impact on treatment decision-making and prognosis., Material and Methods: Fifty-one CDKs in 40 patients were classified neonatally into 3 types: I, reducible (n=28); II, recalcitrant (n=16); and III, irreducible (n=7). Number of anterior skin grooves, range of motion (RoM), flexion deficit and reduction stability were recorded. Depending on reducibility, treatment comprised: physiotherapy with splints, traction with cast immobilization, or surgery. At follow-up, knees were assessed in terms of RoM and stability., Results: Mean age at first consultation was 5.6 days (range: 0-30). Mean age at follow-up was 9 years (range: 1-26). Physiotherapy with splinting achieved stable reduction in all type-I knees. Five type-II knees (31%) required traction, none of which needed surgery. Four type-III knees (57%) required surgery. Outcome was good or excellent in 82% of type-I knees, good in 68% of type II and poor in all type-III knees., Conclusion: The study confirmed the relevance of the present neonatal classification to treatment, with increasing rates of surgical indication and decreasing rates of satisfactory outcome from types I to III. Therapeutic attitude can be graded according to severity of CDK., Level of Evidence: IV, single-center retrospective series., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Unlabelled: Developmental dislocation of the hip (DDH) is frequently, even after reduction, associated with residual acetabular dysplasia. Various surgical techniques are used to correct this, one of which is Dega acetabuloplasty. This osteotomy technique has, however, rarely been assessed in this particular indication. The present study therefore sought to describe the technical details, report clinical and radiological results, and present limitations., Hypothesis: Unlike reorientation osteotomy in children, Dega acetabuloplasty does not lead to a high rate of acetabular retroversion at the end of growth., Patients and Methods: Sixteen Dega acetabuloplasties in 15 patients were assessed on joint range of motion, limp, lower limb length discrepancy and impaired everyday activity, pre-operatively and at end of follow-up. Hips were classified following Wicart et al. (2003). Radiologic assessment comprised Wiberg angle and acetabular index, pre- and post-operatively and at follow-up. Acetabular retroversion was analyzed by crossover sign, and hips were classified following Severin., Results: Median age at surgery was 3 years (range, 1.1-12.2 years) and 10 years (6.4-17.8) at end of follow-up. At end of follow-up, all hips were pain-free and classified as Wicart A, and all activities were allowed. Radiologically, hips were classified as Severin I, II or IV, in 11 (68.5%), 4 (25%) and 1 (6.5%) cases respectively. Wiberg angle rose from a mean 3.3° (-30° to 30°) to 23° (10° to 38°) and acetabular index fell from a mean 31° (25° to 45°) to 20° (5° to 30°) with surgery, and both continued to improve over follow-up: 26° (12-45°) and 13° (3-24°) respectively (P<0.05). Acetabular retroversion was found in 2 of the 10 hips with Y cartilage fusion., Discussion: Modified Dega acetabuloplasty was effective in correcting acetabular dysplasia in DDH. Functional and radiological results were good, with a low rate of acetabular retroversion (2/10), unlike with other techniques., Level of Evidence: Level IV.

Background: Paralysis of the lateral and/or anterior leg muscles can lead to relapse of treated talipes equinovarus., Hypothesis: The muscle function impairment is due to isolated permanent paralysis, and early palliative tendon transfer may prevent recurrence of the deformity., Material and Methods: Forty-two cases of congenital talipes equinovarus that recurred after conservative therapy were reviewed after a mean follow-up of 10 years. In 39 cases, second-line surgery was performed (posteromedial release, n=33; and muscle transfer, n=26). Outcomes were evaluated clinically., Results: Separating the cases into two groups, based on whether muscle transfer was performed, showed a statistically significant difference: muscle transfer intended to restore eversion and/or dorsal flexion of the foot was associated with significantly better functional outcomes., Discussion: In addition to providing etiological insights, the identification of paralysis in patients with talipes equinovarus can influence treatment decisions, depending on the nature of the muscle deficiencies, with the goal of preventing recurrences. Early muscle transfer to restore eversion and/or dorsal flexion of the foot may provide the best functional outcomes by minimizing the need for soft-tissue release., Level of Evidence: IV, retrospective multicentre study., (Copyright © 2012 Elsevier Masson SAS.

Introduction: One possible sequela of obstetric brachial plexus palsy (OP) is impaired external rotation (ER) of the shoulder which, in addition to its functional consequences, can generate a posterior humeral head subluxation or dislocation. The goal of the present study was to assess medium-term clinical and radiological results of release of the subscapularis muscle with transfer of the latissimus dorsi and teres major muscles., Patients and Methods: From 1985 to 1995, a continuous series of 32 OP patients underwent subscapularis muscle release, associated in 24 cases to muscle transfer. Mean age was 2.5 years (range, 1-9.2 years). Shoulder function was assessed by measurement of passive ER and graded according to the modified Mallet classification at 1, 5 and 10 years' follow-up or before revision. The evolution of the glenohumeral deformity was assessed on CT images of glenoid retroversion and the humeral head subluxation (% of humeral head covered), before and 5 years after surgery., Results: Mean postoperative follow-up was 9.5+/-5.6 years. Treatment brought significant improvement in passive ER (mean preoperative and 1-year follow-up values: -10 degrees and 52 degrees, respectively). This explained the good modified Mallet score at 1 year: mean=18.4/25. Subsequent significant progressive degradation was noted: 10 years postoperatively, mean ER amplitude and modified Mallet score were respectively 13 degrees and 15.8. The CT study showed correction of the glenoid retroversion (mean preoperative and 5-year follow-up values: 29 degrees and 18 degrees, respectively), and of the humeral head subluxation (mean preoperative and 5-year follow-up values: 25 and 39%, respectively). Surgical revision was indicated six times (five patients): two latissimus dorsi and teres major transfers (not performed initially) and four derotational humeral osteotomies. Three-quarters of the patients who did not initially have muscle transfer had to be reoperated or else showed ER insufficiency at last follow-up., Discussion and Conclusion: Surgical treatment produces objective functional gain, even if this diminishes over time. Moreover, it prevents or corrects posterior subluxation of the shoulder. It is indicated when passive ER amplitude is negative. It seems advisable to associate release to muscle transfer., Level of Evidence: Level IV Retrospective study., (Copyright 2010 Elsevier Masson SAS. All rights reserved.)

Unlabelled: Proximal location of congenital pseudarthrosis of the tibia (CPT) is uncommon, and its management challenging, risking to end in amputation. We here report a case of proximal CPT managed in a limb-sparing perspective and followed up until the end of growth. A 17-year-old girl presented with type-1 neurofibromatosis and proximal CPT. Initial X-ray showed severe pseudarthrosis of the tibia with bone atrophy, 12-cm shortening and femorotibial and femoropatellar dislocation. Inter-tibiofibular graft and fibular tibialization were performed. At end of follow-up (age 33 years), fusion had been obtained. For orthoprosthetic and cosmetic reasons, a Boyd amputation of the tarsus was performed when the patient was 22 years of age. The functional result was very good, with 0-100 degrees knee mobility. CPT, when proximal, completely disorganizes the knee joint, which is otherwise usually unaffected by this pathology. To achieve a good result, a limb-sparing treatment should combine correction of the tibial axis and of the dislocation of the knee, fibula osteosynthesis and bone graft., Level of Evidence: Level IV retrospective, (2009 Elsevier Masson SAS.
