Abstract
Aims The aim of this study is to evaluate the surgical treatment with the best healing rate for patients with proximal femoral unicameral bone cysts (UBCs) after initial surgery, and to determine which procedure has the lowest adverse event burden during follow-up. Methods This multicentre retrospective study was conducted in 20 tertiary paediatric hospitals in France, Belgium, and Switzerland, and included patients aged < 16 years admitted for UBC treatment in the proximal femur from January 1995 to December 2017. UBCs were divided into seven groups based on the index treatment, which included elastic stable intramedullary nail (ESIN) insertion with or without percutaneous injection or grafting, percutaneous injection alone, curettage and grafting alone, and insertion of other orthopaedic hardware with or without curettage. Results A total of 201 patients were included in the study. The mean age at diagnosis was 8.7 years (SD 3.9); 77% (n = 156) were male. The mean follow-up was 9.4 years (SD 3.9). ESIN insertion without complementary procedure had a 67% UBC healing rate after the first operation (vs 30% with percutaneous injection alone (p = 0.027), 43% with curettage and grafting (p = 0.064), and 21% with insertion of other hardware combined with curettage (p < 0.001) or 36% alone (p = 0.014)). ESIN insertion with percutaneous injection presented a 79% healing rate, higher than percutaneous injection alone (p = 0.017), curettage and grafting (p = 0.028), and insertion of other hardware combined with curettage (p < 0.001) or alone (p = 0.014). Patients who underwent ESIN insertion with curettage had a 53% healing rate, higher than insertion of other hardware combined with curettage (p = 0.009). The overall rate of postoperative complications was 25% and did not differ between groups (p = 0.228). A total of 32 limb length discrepancies were identified. Conclusion ESIN insertion, either alone or combined with percutaneous injection or curettage and grafting, may offer higher healing rates than other operative procedures. Limb length discrepancy remains a major concern, and might be partly explained by the cyst's location and the consequence of surgery. Therefore, providing information about this risk is crucial.

Frontal correction assessment in severe adolescent idiopathic scoliosis surgery using halo gravity traction before to posterior vertebral arthrodesis: a multicenter retrospective observational study. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024; 33:713-722. [PMID: 38135731 DOI: 10.1007/s00586-023-08062-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Revised: 10/01/2023] [Accepted: 11/21/2023] [Indexed: 12/24/2023]
Abstract
PURPOSE Preoperative preparation with halo gravity traction (HGT) has several advantages but is still controversial. A multicenter, observational, retrospective study was conducted to determine whether HGT provides better frontal correction in surgery for adolescent idiopathic scoliosis (AIS). METHODS Between 2010 and 2020, all patients who underwent posterior spinal fusion (PSF) AIS with a Cobb angle greater than 80° were included. The included patients who underwent HGT were compared (complications rate and radiographic parameters) to patients who did not undergo traction (noHGT). For patients who underwent HGT, a spinal front X-ray at the end of the traction procedure was performed. RESULTS Sixty-four in noHGT and forty-seven in HGT group were analyzed with a 31-month mean follow-up. The mean ratio of Cobb angle correction was 58.8% in noHGT and 63.6% in HGT group (p = 0.023). In HGT, this ratio reached 9% if the traction lasted longer than 30 days (p = 0.009). The complication rate was 11.7% with a rate of 6.2% in noHGT and 19.1% in HGT group (p = 0.07). In patient whose preoperative Cobb angle was greater than 90°, the mean ratio of Cobb angle correction increases to 6.7% (p = 0.035) and the complications rate increased to 14% in the no HGT group and decreased to 13% in the HGT group (p = 0.9). CONCLUSION HGT preparation in the management of correction of AIS with a Cobb angle greater than 90° is a technique providing a greater frontal correction gain with similar complication rate than PSF correction alone. We recommend a minimum halo duration of 4 weeks.

Open fractures of the limbs in children and adolescents. Orthop Traumatol Surg Res 2024; 110:103771.

Abstract
Open fracture is rare in children, raising dual issues of sepsis and mechanics. Here, we address certain practical questions regarding childhood open fracture. Should the recognized adult classifications be used in children? Two classifications exist for adults, without pediatric specificities; of these, we recommend Gustilo's, as being more precise in its description of severe grades. Is there any consensus on emergency prophylactic antibiotic therapy in children? The risks seem to be the same, and 24hours' prophylactic antibiotic therapy should be initiated as soon as possible, as in adults. What are the most recent guidelines on time to treatment, type of internal fixation and possible associated procedures in tibial fracture in children? Wound cleansing is indispensable. Treatment under anesthesia can be delayed up to 24hours in the absence of neurovascular complications on condition that antibiotic therapy is implemented immediately. In Gustilo grade I and II, or IIIA, external fixation is not systematic and non-operative treatment or intramedullary nailing is possible. In grades IIIB and IIIC, external fixation is the rule, although conversion is possible if indicated early enough. Do the particular cases of nail bed injury or lawn mower foot injury in children require specific management? Nail bed injury is not to be minimized and should be treated strictly. In case of serious accidents with garden equipment, initial wound care in surgery should be economic, but experienced practitioners should weigh the risk/benefit ratio between conservation and early amputation.

Grisel's syndrome and Down syndrome: a case report. INTERNATIONAL JOURNAL OF BURNS AND TRAUMA 2023; 13:94-98. [PMID: 37215515 PMCID: PMC10195222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 02/02/2023] [Indexed: 05/24/2023]
Abstract
Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joint following an inflammatory process in the upper respiratory tract. Patients with Down syndrome have higher risks of developing atlantoaxial instability. This issue is mainly due to low muscle tone, loose ligaments, and alterations to the bone in patients with Down syndrome. Accompaniment of Grisel's syndrome and Down syndrome was not perused in recent investigations. To our knowledge, only one case of Grisel's syndrome in an adult patient with Down syndrome has been reported. In this study, we present a case of Grisel syndrome in a 7-year-old boy with Down syndrome following lymphadenitis. A 7-year-old boy with Down syndrome was admitted to the orthopedic ward of Shariati hospital with a possible diagnosis of Grisel's syndrome and treated with mento-occipital traction for ten days. In this case report, we represent a child with Down syndrome with Grisel's syndrome for the first time. We also imitated a simple and applicable non-surgical treatment for Grisel's syndrome.

Prevalence and risk factors for scoliosis in adults with closed and open spina bifida: A large, cross-sectional study. Ann Phys Rehabil Med 2022; 66:101685. [PMID: 35717001 DOI: 10.1016/j.rehab.2022.101685] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 04/06/2022] [Accepted: 05/16/2022] [Indexed: 12/04/2022]
Abstract
BACKGROUND Scoliosis develops in a proportion of children with myelomeningocele; however, little is known about scoliosis in adulthood and in other forms of spina bifida (SB). OBJECTIVES The aims of this study were to describe the prevalence of scoliosis and identify risk factors for its development in a large cohort of adults with open and closed SB. METHODS This was a cross-sectional study of data from 580 adults with SB attending their first consultation at a French multidisciplinary referral centre for SB. Sex, anatomical location and type of SB (open or closed), neurological level, back pain and ambulatory status (new Functional Ambulation Classification [new FAC]) were compared in adults with and without scoliosis. These characteristics were used to determine scoliosis risk factors. RESULTS In total, 331 adults fulfilled the inclusion criteria: 221 had open and 110 had closed SB. Of these, 176 (53%) had scoliosis: 57% open and 45% closed SB. As compared with individuals without scoliosis, those with scoliosis more frequently had open SB (p=0.03), more cranially located SB (p<0.0001), more severe neurological deficits (p≤0.02) and poorer walking ability (mean new FAC score 3.5 [SD 3.3] vs 6.1 [2.6], [p<0.0001]). In total, 69% had chronic back pain, with no difference in frequency between those with and without scoliosis. The odds of scoliosis was associated with asymmetrical motor level and a new FAC score <4 (odds ratio 0.46, p<0.006, and 0.75, p<0.0001, respectively). CONCLUSION About half of adults with open and closed SB had scoliosis. Back pain was frequent in those both with and without scoliosis. Individuals with low walking ability and an asymmetrical motor level should be monitored early and continuously to limit the consequences of scoliosis during their lifetime. A major issue is to determine how scoliosis evolves and to determine appropriate monitoring and treatment strategies for individuals at risk.

Functional and radiological outcome of subtalar arthroereisis for flexible pes planovalgus in children: A retrospective analysis. Orthop Traumatol Surg Res 2022:103488. [PMID: 36435370 DOI: 10.1016/j.otsr.2022.103488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Revised: 05/31/2022] [Accepted: 06/03/2022] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Pediatric idiopathic pes planovalgus can correct itself with growth. Otherwise, in the event of functional impairment and after failed conservative treatment, surgery can be considered. Based on a multicenter retrospective study, we report the functional and radiographic results obtained after subtalar arthroereisis. HYPOTHESIS We hypothesized that this surgery improves functional and radiological parameters in childhood. MATERIAL AND METHOD Forty-eight medical records of children (78 feet) operated on between 2010 and 2019 were studied. Functional (FAOS score) and radiographic (Djian angle, calcaneal slope, lateral talocalcaneal divergence and calcaneus/M5 alignment, talonavicular coverage measurement, AP talocalcaneal divergence) results were studied. The analysis of these different criteria was carried out between the preoperative period and the last follow-up. RESULTS The functional outcome was satisfactory with an average FAOS questionnaire score of 95.5 out of 100 total points. All the radiographic parameters studied were significantly improved (p<0.001). The average age at the time of surgery was 11.3 years (range: 7 to 16) with a mean follow-up of 35 months (range: 18 months to 84). Spontaneous screw expulsion and subtalar pain were the main complications found. DISCUSSION The results obtained are consistent with those in the literature. The age at the time of the surgery is an essential factor to consider with the goal of optimal correction. CONCLUSION This technique is reliable and effective in the short term. It can be offered as first-line therapy in the management of symptomatic pes planovalgus in children. The follow-up is short, which necessitates longer term studies of this population. The ideal age for surgery remains to be determined. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Spinal osteochondroma (or exostosis) is a rare benign tumour whose clinical manifestations are delayed due to their slow growth and location. Few studies have addressed the characteristics and the diagnostic and therapeutic peculiarities of spinal osteochondroma in children. The objective of this multicentre observational study was to assess the outcomes of a cohort of children after surgery for spinal osteochondroma. HYPOTHESIS Surgical excision of spinal osteochondroma in children is not followed by complications or recurrences. MATERIAL AND METHODS We included consecutive children who had surgery between 2010 and 2018 at any of eight participating centres to remove spinal osteochondromas. The cause, clinical manifestations, and location of the lesions were collected. The surgical outcomes were evaluated after at least 2 years' follow-up. RESULTS We identified 22 patients who had surgery to remove 26 spinal osteochondromas at a mean age of 12.8±2.6 years. Among them, 7 had a solitary osteochondroma (SO group) and 15 had hereditary multiple osteochondromas (HMO group). At diagnosis, 72% of patients had clinical signs (spinal pain, n=4; one or more lumps, n=5; and neurological manifestations, n=3). In the HMO group, the diagnosis was made during routine MRI screening for tumours involving the spinal canal. Most osteochondromas involved the cervical spine (n=13), with no difference between the two groups (p=0.9). The lamina was the most common location but 54% of the tumours were growing within the canal (92% in the HMO group). After a mean follow-up of 5.2±4.4 years, no patients had experienced any recurrences or complications related to the disease or treatment. DISCUSSION Surgical excision of spinal osteochondromas in children is effective, with no medium-term recurrences. Our results also confirm the low peri-operative morbidity, even when the canal is involved, and the absence of any effect at last follow-up on spinal alignment. All patients with neurological manifestations at diagnosis made a full recovery. LEVEL OF EVIDENCE IV, retrospective observational cohort study.

Coronal STIR MRI sequences in unexplained limping in children under 6 years old: A single-center retrospective study of 130 cases. Arch Pediatr 2022; 29:494-496. [PMID: 36100490 DOI: 10.1016/j.arcped.2022.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 02/22/2022] [Accepted: 08/05/2022] [Indexed: 10/14/2022]
Abstract
INTRODUCTION Limping is a common presenting symptom in young children. Clinical examination backed up by laboratory analysis, standard radiography, and/or ultrasound may fail to determine the diagnosis, and limping may prove persistent, requiring repeated consultation. Magnetic resonance imaging (MRI) can suggest the etiology or provide welcome reassurance when normal. We advocate the use of MRI in cases of persistent unexplained limping in young children. The study hypothesis was that coronal short TI inversion recovery (STIR) MRI has good negative predictive value (NPV) in unexplained limping in children under 6 years of age. MATERIAL AND METHOD Coronal STIR MRI sequences were analyzed in 130 children younger than 6 years (84 boys, 46 girls) during the period April 2007 to May 2017. They extended from the lower thoracic spine down to the feet. Agreement was analyzed between the radiologist's initially suggested diagnosis and the pediatric orthopedic specialist's final diagnosis. RESULTS Overall, 49 scans were normal (37.7%) and 81 abnormal (62.3%). The mean age at MRI was 32.3 months. Coronal STIR MRI had 98% NPV. There was 99.2% agreement between the radiologist's diagnosis and the final diagnosis. DISCUSSION The recently reported contribution of STIR MRI in bone and joint infections was extended to unexplained limping. CONCLUSION First-line MRI with coronal STIR sequences improved the diagnostic efficacy, thanks to its speed and relative lack of movement artifacts.

Abstract
Bone lengthening surgeries are difficult procedures for both the patient and the professional. Complications are common and pediatric orthopedists have been working to reduce them. The discovery of progressive bone lengthening was a first step in improving these procedures, followed by the advent of external fixators. More recently, internal lengthening systems have emerged as one of the greatest technological advances in these procedures. Bone lengthening with an electromagnetic nail, which is becoming increasingly popular, has drastically reduced the complications of these surgeries.

Abstract
Juvenile hallux valgus is one of the most common pathologies of the forefoot in children and adolescents. Nevertheless, its treatment is still controversial. This deformity has some distinct anatomical features, particularly a lateral tilt of the articular facet of the head of the first metatarsal and congenital metatarsus adductus, which often occur in combination. Some mediocre surgical treatment results can be explained by the lack of correction of all these factors when we approach the problem as we would in adults. A double osteotomy to correct the DMAA and varus of the first metatarsal is a good solution in most cases with satisfactory functional outcomes. A percutaneous approach seems efficient in the pediatric population, given that the periosteum and growth plates, which are very active in younger children, help the osteotomies to heal and remodel. Guided growth surgery - using this approach is a viable alternative in this age bracket. Finally, minimally invasive surgery for juvenile hallux valgus allows another surgery to be done on minimally or undamaged tissues if needed later on.

Proximal junctional kyphosis is a rebalancing spinal phenomenon due to insufficient postoperative thoracic kyphosis after adolescent idiopathic scoliosis surgery. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:1988-1997.

Abstract
PURPOSE Many authors tried to explain proximal junctional kyphosis (PJK) after adolescent idiopathic scoliosis (AIS) surgery by looking for risk factors. Latest publications focus on sagittal alignment. Each healthy adolescent has a specific thoracic kyphosis (TK) depending on their pelvic parameters and lumbar lordosis (LL). The objective of this work is to determine if the difference between TK at follow-up (TKFU) and the patient-specific TK (PSTK) plays a role in PJK occurrence after AIS surgery. The secondary objective was to find other risk factors. METHODS We analyzed retrospectively 570 thoracic AIS who underwent a posterior thoracic fusion from nine centers. The series was separated in two groups: with and without PJK. PSTK was calculated with the formula PSTK = 2(PT + LL-PI). TK Gap was the difference between TKFU and PSTK. Logistic regression was utilized to test the impact of TK Gap and other known risk factors on PJK occurrence. RESULTS Univariate analysis showed 15 factors significantly different between the groups. In a multivariate analysis, three factors had a strong significant influence on PJK: TKFU, TK Gain and TK Gap. Four additional factors affected the rate of PJK: Posterior translation on two rods, preoperative TK, preoperative LL and number of instrumented vertebrae. CONCLUSION PJK is related to the insufficient TK at follow-up, compared to the specific TK that every patient should have according to their pelvic parameters. PJK incidence is significantly reduced by a strong gain in TK and a thoracic selective fusion which leaves the proximal lumbar vertebrae free. LEVEL OF EVIDENCE I Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.

Abstract
INTRODUCTION Madelung's deformity is rare. Treatment often consists in radial or ulnar osteotomy, Vickers' ligament resection or ulnar epiphysiodesis. The present multicenter retrospective study reports clinical and radiographic results in various surgeries. The study hypothesis was that early surgery improves outcome. MATERIAL AND METHOD Files were analyzed for 36 children (47 wrists) operated on between 1998 and 2015. Mean age at diagnosis was 12 years (range, 6-15 years). Mean follow-up was 7.2 years (range, 2-17.4 years). Two age groups were distinguished: 6-11 and 12-17 years. Endpoints were esthetic, functional (Mayo Wrist Score: MWS) and radiographic [lunate fossa angle (LFA), radial height (RH), lunatum cover rate (LCR), ulnar head translation (UHT), lunatum ascension (LA)]. Techniques mainly comprised distal radius osteotomy (DRO) with ulnar shortening osteotomy (USO), and Vickers' ligament resection (VR), either isolated or associated to osteotomy. RESULTS Age at surgery guided choice of technique, but did not impact results. VR gave better functional results when performed in young children; it was mainly performed in the 6-11 years age group, providing very satisfactory results (7 out of 8 wrists) with excellent function (7 out of 8), without improving radiographic parameters; in the 12-17 years age group, even when esthetic results were excellent, functional results were only good-to-acceptable (3 out of 5 wrists) and 1 result was poor. DRO+USO was mainly performed in the 12-17 years age group, with very satisfactory or satisfactory results (8 out of 10 wrists) and excellent function (6 out of 10). DRO+USO appeared to be an option of choice, significantly improving radiographic parameters and correcting the deformity (24.5° improvement in LFA (p=0.0033) and 36.2% improvement in LCR (p=0.0103)). DRO+USO+VR was mainly implemented in the 12-17 years age group, with very satisfactory results (3 out of 4 wrists) and excellent-to-good MWS in most cases (3 out of 4), but without significant radiographic improvement. DISCUSSION Esthetic and functional results were comparable regardless of age, except for VR, which gave better functional results in the 6-11 years age group, but without significant difference. CONCLUSION The present study showed that, regardless of children's age, surgery provided esthetic, functional and radiographic benefit, although no decision-tree could be drawn up.

Abstract
The biomechanical influence of brace treatment for scoliosis is not understood. This prospective pilot study analyzed reliability of a system based on 100% textile sensors for measurement of pressure exerted by brace on trunk. Evaluation of modifications during changes in the location of the support zones and variations in amplitude of the pressure was observed in four patients, when considering three main daily positions mimicking day and nighttime wear. A calibration step allowed the determination of a conversion law between sensor data and pressure unit using a second order polynomial function with a high r2 of 0.99. This prototype is the first of a new generation. Experimental pressure distribution could be useful for the further brace development.

Abstract
BACKGROUND Upper limb injuries are common in children. When required, closed fracture reduction can be performed in the emergency department without general anaesthesia but causes pain. The primary objective of this study was to assess an oral analgesia protocol for fracture reduction without general anaesthesia. The secondary objectives were to look for associations linking pain intensity to age, sex, and waiting time and to determine the frequency of secondary displacement requiring closed reduction or internal fixation under general anaesthesia at the 1-week follow-up visit. HYPOTHESIS An oral analgesia protocol combining a loading dose of morphine with other medications would provide sufficient pain control to obviate the need for general anaesthesia. MATERIAL AND METHODS A prospective observational single-centre study was conducted over a 15-month period (July 2017-October 2018) in consecutive patients younger than 16 years who required reduction of a displaced upper-limb fracture. All patients received the same oral combination of paracetamol (15mg/kg), ibuprofen (7.5-10mg/kg), and a loading morphine dose (0.5mg/kg, up to 20mg) 1hour before the procedure. Patients given morphine more than 2hours before the procedure and those with persistent pain were given an additional morphine dose (0.2mg/kg, up to 10mg). An equimolar mixture of oxygen and nitrous oxide was administered during reduction. An appropriate scale was used to measure pain intensity before, during, and 15minutes after the procedure. Cases of secondary displacement requiring further reduction or internal fixation under general anaesthesia at the 1-week follow-up visit were recorded. RESULTS The 101 study patients (73 male and 28 female) had a mean age of 9.4 years (range, 2-15 years). Mean pain scores were 5.0±2.6 at admission and 2.1±2.3, 2.6±3.3, and 1.3±2.2 before, during, and after reduction, respectively. Pain intensity during reduction was significantly associated with age. The analgesia was deemed satisfactory by 94 patients and 90 parents. General anaesthesia for further treatment was required in 10 (9.9%) patients, either on the day after the initial treatment, due to inadequate reduction (n=8), or at the 1-week visit, due to secondary displacement (n=2). DISCUSSION Oral morphine in a sufficient dosage given in combination with other medications was effective and well tolerated when used to control pain during upper-limb fracture reduction. Pain intensity was not significantly associated with sex. In contrast, pain was significantly more severe in the patients older than 10 years of age. The proportions of patients requiring further reduction or internal fixation were consistent with previously published data. Most patients and parents were satisfied with the analgesia protocol. CONCLUSION A multimodal oral analgesia protocol provides sufficient pain relief to allow closed reduction of upper-limb fractures in children at the emergency department. This management strategy provided high satisfaction rates in both the patients and their parents. LEVEL OF EVIDENCE II, prospective observational study.

Correction of thoracic adolescent idiopathic scoliosis via a direct convex rod manoeuvre. Orthop Traumatol Surg Res 2019; 105:1171-1174.

Abstract
The various techniques available for scoliosis surgery via the posterior approach involve positioning implants on either side of the curve and reducing the deformity by manoeuvres on the concave rod or simultaneously on both rods. Correction solely via a direct convex rod manoeuvre would eliminate the need for implants on the concave side. This technique was used to treat thoracic adolescent idiopathic scoliosis in 23 patients with a mean age of 14 years and 9 months. Low-dose biplanar EOS radiographs were obtained before surgery, on post-operative day 7, and at last follow-up (at least 2 years after surgery) to allow comparisons of Cobb's angle (72°, 33°, and 35°, respectively), thoracic kyphosis (21°, 29°, and 26°), lumbar lordosis (58°, 50°, and 55°), and apical vertebra rotation (-26°,-12°, and-11°). Although scoliosis requires corrections in all three dimensions, this technique seems to produce satisfactory outcomes while obviating the need for implants on the concave side, thereby decreasing the risk of iatrogenic adverse events.

Correlations between physical and ultrasound findings in congenital clubfoot at birth. Orthop Traumatol Surg Res 2018; 104:651-655.

Abstract
BACKGROUND At birth, clinical classifications are the only available tools for evaluating the severity of congenital clubfoot. Ultrasound provides an assessment of the anatomical abnormalities. The objective of this study was to assess correlations between physical and ultrasound findings at birth. HYPOTHESIS Physical and ultrasonography provide different findings in congenital clubfoot and should therefore be used in conjunction. MATERIAL AND METHOD One hundred and forty-five clubfeet in 108 patients born between 2006 and 2010 were included in a retrospective study. Clubfoot severity was classified using two methods, the modified Dimeglio classification based on physical findings and an ultrasound score based on the talo-navicular angle (TNA) and metaphyso-talo-calcaneal angle (MTCA). Each of these two methods distinguished three severity grades. Agreement between the two methods was assessed by computing the coefficient. RESULTS The results confirmed the hypothesis by showing low agreement between the clinical and ultrasound classifications. The severity grades were identical with the two methods for only 83/145 (57%) feet. The coefficient was 0.086. DISCUSSION The two ultrasound views used to measure the TNA and MTCA, respectively, added an assessment of the three main deformities that characterise congenital clubfoot (equinus, adduction of the forefoot, and adduction of the calcaneo-pedal unit). Ultrasonography complements the physical examination at birth. In the future, using both physical examination and ultrasound scanning to monitor babies with clubfoot may allow early treatment adjustments aimed at optimising the outcome.

Abstract
PURPOSE Preliminary results of magnetically controlled growing rods (MCGR) are encouraging. However, only short case series of MCGR for the treatment of early onset scoliosis (EOS) have been reported. Our aim was to evaluate its effectiveness and complications. METHODS We report a 30-case retrospective, consecutive, multicenter series of MCGR. Effectiveness was judged upon: deformity correction and difficulties to achieve desired distraction. Secondary endpoints included complications and revision surgeries. RESULTS Median age at surgery was 9.1 years (5-13). Mean follow-up was 18.4 months (12-33.9). Mean Cobb angle was 66° preoperatively and 44° at latest follow-up. MCGR has avoided an average of 2.03 scheduled surgical procedures per patient compared to traditional growing rod (GR). The intended total length gain was 40.1 mm per patient (5-140) and the total measured length gain was 21.9 mm (45.5% discrepancy). There were 24 complications: 7 proximal pull-outs of the hooks, 3 rod breakages, 6 failures of the lengthening of which 4 complete blockages and 2 complete blockages followed by backtracking, 1 proximal junctional kyphosis, 1 wound dehiscence, 1 superficial infection, 1 deep infection requiring implant removal, 1 pulmonary embolism, 1 pulmonary insufficiency, 1 secondary lumbar scoliosis, and 1 painful outpatient distraction. Eight patients had a gradual loss of effectiveness of distractions. There were 13 revision surgeries in 9 patients. CONCLUSIONS MCGR provides satisfactory deformity correction and avoids repeated surgical procedures for lengthening. However, it has substantial complication rate. Although less frequent than in GR, the law of diminishing returns also applies to MCGR.

Abstract
INTRODUCTION The over-the-top position of the femoral metaphyseal tunnel during extraphyseal ligament reconstruction of the anterior cruciate ligament (ACL) according to Clocheville may be responsible for negative anisometry. Until now, the follow-up of children operated using this pediatric technique was limited to screening for iatrogenic epiphysiodesis and the search for postoperative clinical instability. The objective of this study was to measure residual laxity using objective tests, to quantify muscle recovery, and to evaluate the quality of life of these patients in terms of the sports activities. MATERIAL AND METHODS Eleven patients with a mean age of 13.5years were seen at a mean 2.1years of follow-up. They underwent objective clinical tests (GNRB(®) arthrometer and CON-TREX(®) dynamometer) as well as subjective questionnaires (IKDC and KOOS). RESULTS No significant difference was found between the healthy knee and the operated knee for either the GNRB(®) at 134N (P=0.79) or at 200N (P=0.98). The CON-TREX(®) system allowed us to measure a median percentage of quadriceps recovery of 80.7% (range, 52.2-114.5) in terms of muscle power (60°/s) and 81.2% (range, 51.6-109.6) for muscle response (180°/s). The median subjective IKDC score was 94.73/100 (range, 73.68-98.93); 72.7% of the patients resumed competitive sports. DISCUSSION This study's lack of statistical power did not show a significant difference in terms of residual laxity at rest of GNRB(®) transplants, while a mean differential of +0.4mm was observed. Although pediatric transphyseal ligament reconstruction techniques are increasingly used, the Clocheville technique remains, in our opinion, an attractive surgical alternative in the youngest subjects, with no major risk of iatrogenic epiphysiodesis even though it is theoretically anisometric.

Validity and utility of monopolar spinal cord stimulation in pediatric scoliosis surgery.

Abstract
PURPOSE To assess the validity and utility of monopolar stimulation (between a peridural needle and a large adhesive anode placed in the sternal area) for intraoperative monitoring in scoliosis surgery. METHODS This procedure was assessed during 41 operations involving either arthrodesis with posterior instrumentation or a Vertical Expandable Prosthetic Titanium Rib (VEPTR). Responses evoked by monopolar stimulation were compared with those evoked by bipolar stimulation between two epidural needle electrodes. Potentials evoked by monopolar stimulation in the upper limbs were compared with those evoked in the lower limbs during the same stimulation procedure. RESULTS Monopolar stimulation yielded equivalent and, if anything, more stable responses in the lower limbs. Recording in the upper limbs was satisfactory and allowed a decrease in responses to be detected in two patients. Acceptable thresholds for changes in amplitude relative to baseline were 40 % for upper limbs and 30 % for lower limbs. CONCLUSIONS Monopolar stimulation can be used to monitor the spinal cord during surgery for scoliosis correction. This procedure is more convenient for the surgeon and allows for the combined recording of responses in all four limbs, which can be useful in the case of surgical techniques such as those involving a VEPTR.

Abstract
The precise etiology of childhood and adolescent spondylolisthesis (SPL) remains undetermined, but would seem to be multifactorial, deriving from anthropological adaptations of spinal sagittal balance combined with microtraumatic, genetic and dysplastic factors. Description of sagittal parameters not only lends weight to etiopathogenetic hypotheses, but also seeks to improve the classification of severity so as to optimize treatment according to clinical and radiological presentation. Thus, surgery should not only stabilize the lumbosacral junction by solid fusion but also correct pelvic abnormalities so as to restore overall sagittal balance in the long-term, without requiring spinal, pelvic or sub-pelvic compensation and with the lowest possible energy cost. Methods are still under debate; surgical technique, whether instrumental or not and whether aiming at in situ fusion or to correct lumbosacral deformity, all incur neurological risk of which child and family should be informed. Only long-term follow-up of functional results on quality-of-life scales, combined with radiological results for surgery aiming at lumbosacral angle correction, will be able to demonstrate superiority over in situ fusion surgery.

Abstract
Compression of the common peroneal nerve by synovial cysts of the tibiofibular joint is a rare disease. Two macroscopic forms may be encountered: extraneural cysts and intraneural cysts. In a review of the literature, we found only three pediatric cases of common peroneal nerve palsy due to extraneural cysts and about 60 cases reported in adults. Taking advantage of the clinical history of two children operated in our department for this disease, we describe this uncommon entity, which must be diagnosed and treated rapidly. Even in the presence of severe clinical and electrophysiological symptoms, a full clinical recovery is possible, as observed in these two children. However, follow-up is needed because recurrence is possible.

Abstract
PURPOSE To describe two cases of a dorsal vertebral hemangioma diagnosed in a 12- and 14-year-old child successfully treated with vertebroplasty. METHOD Cases reports. RESULTS Two cases of aggressive vertebral hemangiomas were diagnosed and treated in two independent institutions. Percutaneous vertebroplasty was then decided. Bipedicular vertebroplasty was performed under general anesthesia, under biplanar fluoroscopic guidance. The injection of acrylic cement filled the entire vertebral body without significant leakage. At last follow-up, the clinical and radiographic outcome was very good. In one patient, last control radiographs showed a gap between the end plates and the cement, spinal growth seemed to have resumed. CONCLUSION Vertebral hemangioma is rare in pediatric patients, and its diagnosis requires meticulous and regular clinical examinations and a combination of imaging studies, particularly an MRI and a CT scan, which can assess the aggressiveness of the lesion. Vertebroplasty seems to be an effective and safe treatment of this benign tumor in children with stable outcome at 2-year follow-up. Spinal growth may resume despite the aggressiveness of both the tumor and the treatment.

Abstract
BACKGROUND Surgical treatment of early-onset scoliosis has greatly developed in recent years. Early-onset scoliosis covers a variety of etiologies (idiopathic, neurologic, dystrophic, malformative, etc.) with onset before the age of 5 years. Progression and severity threaten respiratory development and may result in respiratory failure in adulthood. Many surgical techniques have been developed in recent years, aiming to protect spinal and thoracic development. MATERIAL AND METHODS Present techniques are based on one of two main principles. The first consists in posterior distraction of the spine in its concavity (single growing rod, or vertical expandable prosthetic titanium rib [VEPTR]), or on either side (dual rod); this requires iterative surgery, for lengthening, unless motorized using energy provided by a magnetic system. The second option is to use spinal growth force to lengthen the assembly; these techniques (Luque Trolley, Shilla), using a sliding assembly, are known as growth guidance. RESULTS These techniques are effective in controlling early scoliotic deformity, and to some extent restore spinal growth. However, they show a high rate of complications: infection, rod breakage, spinal fixation pull out and, above all, progressive spinal stiffness, reducing long-term efficacy. Respiratory gain is harder to assess, as thoracic expansion does not systematically improve respiratory function, particularly due to impaired compliance of the thoracic cage.

Abstract
Using a nonvascularized fibular graft is part of the therapeutic arsenal for filling bone loss defects. It is conventionally performed by open surgery. The authors propose a minimally invasive technique for harvesting a free fibular graft. The fibula was removed subperiosteally by two or three small incisions in five patients with a mean age of nine years and nine months. The mean surgical time was 21 min and 40.5% of the length of the fibula was harvested. At the donor site, we found no removal-related complications, regeneration of the fibula was observed in 80% of cases, and the cosmetic result was considered excellent by all patients with a mean 4.3 years follow-up. This minimally invasive technique is simple and fast, with very low morbidity in our experience.

Abstract
BACKGROUND Intraoperative monitoring (IOM) has been proven to decrease the risk of neurological injury during scoliosis surgery. The vertical expandable prosthetic titanium rib (VEPTR) is a device that allows spinal growth. However, injuries to the spinal cord and brachial plexus have been reported after VEPTR implantation in 2 and 5% of patients, respectively. Simultaneous monitoring of these two structures requires the use of multiple time-consuming and complex methods that are ill-suited to the requirements of paediatric surgery, particularly when repeated VEPTR lengthening procedures are needed. We developed a monopolar stimulation method derived from Owen's monitoring technique. This method is easy to implement, requires only widely available equipment, and allows concomitant monitoring of the spinal cord and brachial plexus. The primary objective of this study was to assess the reliability of our technique for brachial plexus monitoring by comparing the stability of neurogenic mixed evoked potentials (NMEPs) at the upper and lower limbs. HYPOTHESIS We hypothesised that the coefficients of variation (CVs) of NMEPs were the same at the upper and lower limbs. MATERIAL AND METHODS Twelve VEPTR procedures performed in 6 patients between 1st January 2012 and 1st September 2014 were monitored using a monopolar stimulating probe. NMEPs were recorded simultaneously at the upper and lower limbs, at intervals of 150 s. The recording sites were the elbow over the ulnar nerve and the popliteal fossa near the sciatic nerve. Wilcoxon's test for paired data was used to compare CVs of the upper and lower limb NMEPs on the same side. RESULTS Mean CV of NMEP amplitude at the lower limbs was 16.34% on the right and 16.67% on the left; corresponding values for the upper limbs were 18.30 and 19.75%, respectively. Mean CVs of NMEP latencies at the lower limbs were 1.31% on the right and 1.19% on the left; corresponding values for the upper limbs were 1.96 and 1.73%. The risk of type I error for a significant difference between the upper and lower limbs was 0.5843 on the right and 0.7312 on the left for NMEP amplitudes and 0.7618 on the right and 0.4987 on the left for NMEP latencies. CONCLUSION Using an epidural active electrode and a sternal return electrode allows simultaneous stimulation of the cervical spinal cord and brachial plexus roots. The NMEPs thus obtained are as stable (reliable) at the upper limbs as at the lower limbs. This easy-to-implement method allows simultaneous monitoring of the upper and lower limbs. It seems well suited to VEPTR procedures. LEVEL OF EVIDENCE IV, retrospective single-centre non-randomised study.

Isolated meniscal injuries in paediatric patients: outcomes after arthroscopic repair. Orthop Traumatol Surg Res 2015; 101:173-7.

Abstract
BACKGROUND The management of isolated meniscal tears in paediatric patients is poorly standardised, and few published data are available. Nevertheless, there is widespread agreement that meniscectomy, even when partial, produces poor outcomes including the premature development of osteoarthritis. HYPOTHESIS Arthroscopic repair of isolated meniscal tears in paediatric patients yields good outcomes and should be attempted routinely. MATERIALS AND METHODS We retrospectively assessed 19 arthroscopic repair procedures performed between 2006 and 2010 by a single surgeon in 17 patients with a mean age of 14 years. In every case, the knee was stable and the meniscus normal before the meniscal tear, which was the only injury. Mean follow-up was 22 months. In all 19 cases, the evaluation included a physical examination, pre-operative magnetic resonance imaging (MRI), and determination of the Tegner and Lysholm scores. Post-operative MRI was performed in 10 cases. RESULTS The outcome was good in 12/17 (70%) patients with significant improvements in the mean Tegner score, from 3.9 to 7.1, and mean Lysholm score, from 55.9 to 85.4, between the pre-operative and post-operative assessments. The clinical outcomes were not significantly associated with time to arthroscopic repair, gender, lesion site, or lesion type. Neither was any correlation demonstrated between clinical outcomes and meniscal healing as assessed by MRI. DISCUSSION The known poor outcomes after meniscectomy in paediatric patients, the results of our study, and previously published data support routine arthroscopic repair of isolated meniscal tears in this age group, regardless of the site and type of injury. In addition, in asymptomatic patients, clinical follow-up is sufficient and post-operative MRI unnecessary. LEVEL OF EVIDENCE Level IV. Retrospective study.

Abstract
Hereditary sensory and autonomic neuropathy type IV (HSAN-IV) is a very rare autosomal recessive disorder characterized by recurrent episodes of unexplained fever, extensive anhidrosis, total insensitivity to pain, hypotonia, and mental retardation. The most frequent complications of this disease are corneal scarring, multiple fractures, joint deformities, osteomyelitis, and disabling self-mutilations. We reported the case of a 12-year-old boy. The goal was to discuss our decision-making and compare this case with cases described in the literature.

Abstract
Thoracic outlet syndrome (TOS) is a rare pediatric syndrome and few cases have been reported in the literature. The authors report the case of a 10-year-old boy with generalized arm pain and neck stiffness. The angiocomputed tomography revealed the presence of a TOS caused by an additional cervical rib and stenosis of the sub-clavian artery. The resection of this rib relieved the patient of his pain during a full year following surgery. This case reminds us that children can also be affected by TOS. When a cervical rib causes TOS, a resection is often necessary.

Pubo-femoral distance: an easy sonographic screening test to avoid late diagnosis of developmental dysplasia of the hip. Eur Radiol 2012; 23:836-44. [PMID: 23080071 DOI: 10.1007/s00330-012-2635-7] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2012] [Revised: 07/04/2012] [Accepted: 07/10/2012] [Indexed: 02/07/2023]
Abstract
OBJECTIVES To propose an easy and reproducible sonographic screening test able to avoid late presentation of developmental dysplasia of the hip (DDH). METHODS The pubo-femoral distance (PFD) cut-off point was determined on 980 infants who underwent ultrasonography of the hips in comparison with the final diagnosis, based on clinical, ultrasound data and follow-up. PFD reproducibility was tested on 52 hips by both an experienced and an inexperienced radiologist. After teaching this screening method to general radiologists, its impact was evaluated by analysing the rate of late diagnosis in an entire administrative area. RESULTS An abnormal PFD threshold above 6 mm gave a sensitivity of 97.4 % for the diagnosis of DDH (271 hips) and a specificity of 84 %. Sensitivity increased to 100 % when taking into consideration children of 1 month or older. The PFD measurement stayed reproducible even in inexperienced hands (k = 0.795). For 3 years, following the extension of screening to all female infants, there was no late diagnosis of DDH in girls in amongst a catchment area of 1 million inhabitants. CONCLUSIONS PFD measurement with a threshold for abnormality of 6 mm at the age of 1 month, without asymmetry above 1.5 mm, could eradicate DDH late diagnosis.

Abstract
Orthopaedic surgeons are often the first physicians to evaluate paediatric patients in the event of delayed walking, gait abnormalities, or parental concern about motor abilities. Therefore, orthopaedic surgeons must be thoroughly familiar with the normal neurodevelopmental stages. Neurological disorders are often first recognised during an orthopaedic evaluation. Minimal neurological abnormalities should be taken as warning signs that require additional investigations. Consequently, the evaluation must follow a strict protocol, even in children referred for apparently trivial functional disorders. We have developed an original physical examination protocol in which the largest possible number of signs is sought in each body position to ensure that the examination is both systematic and rapid. About ten minutes are required when all findings are normal. This protocol is extremely helpful for identifying the cause of the problem that motivated the evaluation or for reassuring the child and family. The main causes of paediatric orthopaedic disorders are cerebral palsy, spinal dysraphism, myopathies, peripheral neuropathies, motor neuron diseases, and intraspinal tumours. In some instances, no definitive diagnosis can be established clinically. In this situation, appropriate orthopaedic treatment can be initiated, although considerable caution is in order when establishing the indications. The cause may be detected only much later, when the clinical manifestations become more prominent.

Abstract
BACKGROUND Localized hypertrophic neuropathy (LHN) of the sciatic nerve in children is a rare condition characterized by a painless neurological deficit in the sciatic nerve territory. OBJECTIVE To demonstrate the role of MRI using a specific protocol and describe the primary findings in LHN. MATERIALS AND METHODS Imaging in four children (age 2 years to 12 years) is presented. All children presented with lower limb asymmetry. Three had a steppage gait. LHN was confirmed by electrophysiological studies and by MRI of the whole sciatic nerve with a dedicated protocol covering the lumbar spine and the lower limb. RESULTS There were four direct MRI findings: (1) linear and focal hypertrophy with progressive enlargement of a peripheral nerve or plexus diameter, (2) abnormal hyperintensity of the nerve on T2-weighted images, (3) preserved fascicular configuration, and (4) variable enhancement after intravenous gadolinium administration. In addition there were atrophy and fatty infiltration of innervated muscles. MRI was helpful for determining the extent of lesions and in excluding peripheral nerve compression or tumour. CONCLUSION MRI of the whole sciatic nerve is the method of choice for diagnosing LHN of the sciatic nerve.

Abstract
The Ponseti method applied to treating idiopathic club foot consists in placing successive corrective casts, possibly an Achilles tendon tenotomy, then derotation braces, a method that has proven its efficacy. This study compared 221 cases of club foot treated with this method between 2002 and 2007 divided into two groups, based on whether or not Achilles tendon tenotomy was performed. Assessment was both clinical and sonographic. We observed clear improvement of the results in the group that underwent Achilles tendon tenotomy and a significant difference in the rate of secondary surgery. The sonographic evaluation also showed improvement of the morphological results. We now systematically propose Achilles tendon tenotomy however severe club foot may be.

Abstract
INTRODUCTION Irreducible developmental dysplasia of the hip (DDH) in newborns is a rare entity. The different obstacles preventing reduction have been described in the literature. HYPOTHESIS A clinical form of DDH with hypertrophy of the cartilage of the acetabular roof (acetabular bulge) can be reliably identified on ultrasound and should probably be defined as a separate entity. MATERIALS AND METHODS For the first time, the authors report their experience, a review of the literature and the radiographic description (ultrasound, arthrography MRI) of irreducible neonatal DDH due to hypertrophy of the cartilage of the acetabular roof (acetabular bulge) in 12 infants (15 hips). RESULTS Neonatal sonography seems to be sufficient to identify this specific clinical entity without any additional work-up. This sonographic sign could help determine the therapeutic strategy earlier in this severe and complex form of DDH.

Abstract
At one month, the acetabular depth from a standard lateral coronal section is 4.6 ± 1.0mm. The correlation between experienced and junior radiologists is high (kappa 0.795). A treshhold of 6mm with a Δ (difference between right and left) less than 1.5mm provides a sensitivity of 100% for the detection of DDH at one month. Universal US screening at one month of all high-risk infants in 2009 resulted in a reduction of delayed diagnosis of DDH (zero girls, two boys) in Ille-et-Vilaine due to continuous medical education of general radiologists.

Abstract
The pelvis may be seen as a single vertebra, between the spine and the femurs. The anatomy of this pelvic vertebra has changed with the evolution of species, notably with the transition to bipedalism, with the consequent appearance of lumbar lordosis. The lumbosacral angle, almost non-existent in other mammals, is at its greatest in humans. Pelvic and spinal radiological parameters reflect the sagittal balance of the spine in bipedal humanity. Applications in the management of spinal imbalance are numerous. Arthrogenic or degenerative kyphosis is the stereotypic example of spinal aging. Postoperative flat back following spine surgery is hard to prevent. Scoliosis surgery in adults should now take greater account of the patient's individual sagittal balance, by analyzing the pelvic and spinal parameters. The extent of arthrodeses performed during adolescence to manage idiopathic scoliosis may also induce problems of balance in adulthood if these elements are not taken into account.

Abstract
We report a first documented case of Serratia fonticola infection in a child with septic arthritis, after falling off his bicycle and an infection with hawthorn thorns. The aetiologic agent was found to be a S. fonticola strain which was first isolated from two synovial fluid samples, only after culture enrichment, with failure of DNA amplification. Accurate diagnostic was done, despite S. fonticola is often considered as an opportunistic pathogenic bacterium. Alone ciprofloxacin treatment was not sufficient to counteract the infection, which was eradicated only after surgical drainage performed twice successively, with secondary removal of a remaining thorn, and treatment with third generation cephalosporin combined with ciprofloxacin for another three months.

Abstract
Chondrodysplasia punctata (CDP) is a rare skeletal dysplasia characterized by stippled epiphyses during infancy. The frequency is probably underdiagnosed because of the large heterogeneity in this group. Many genotypic variations exist. Although cervical instability is commonly seen in many skeletal dysplasias, cervical spine stenosis associated with CDP is very rare. We report a boy with phenotypic features of brachytelephalangic chondrodysplasia punctata (BCDP) who had severe cervical spine stenosis successfully corrected by vertebrectomies of C6 and C7 with a fibular strut graft. We discuss the significance of this association.

Abstract
STUDY DESIGN Prospective clinical study. A quantification of volume and hydration variation of the intervertebral discs, using magnetic resonance imaging (MRI), in the lumbar spine before and after surgery performed in adolescent idiopathic scoliosis (AIS). OBJECTIVES To evaluate an objective quantification of volume and hydration of intervertebral discs below spine fusion in scoliosis surgery. SUMMARY AND BACKGROUND DATA Repercussion of long spine fusion on the free lower lumbar spine is one of the major concerns of scoliosis surgery. However, the evolution of lumbar intervertebral disc below thoracolumbar fusions remains unknown. METHODS MRI performed in the clinical protocol, concerned 28 patients having an idiopathic scoliosis. They underwent posterior instrumentations. MRI was obtained before surgery, after surgery at 3 months and for 15 patients at 1 year. MRI data were posttreated using a custom-made image processing software to semiautomatically derive volume properties of disc, anulus fibrosus, and nucleus pulposus. The nucleus-disc volume ratio was also an indicator of the hydration level. RESULTS The reliability of the three-dimensional reconstruction process was initially verified using an intraoperator reproducibility test. Original preoperative data on disc volume properties were then derived. Postoperative volume variations were quantified in discs below spine fusion taking into account the level of the arthrodesis and the disc location. It showed that the postoperative volume criteria increased significantly for nucleus, disc, and nucleus-disc volume ratio and some magnitude modulation could be conditioned by the location of surgical instrumentation. Some stabilization or reduction depending on disc level and arthrodesis size between 3 months and 1 year is observed in the follow-up. It tended to prove that the recovery of balance physiologic positioning and inherent biomechanical loads could induce a restored hydration of disc, which should favor the remodeling of free segments. CONCLUSIONS This work was the first report dealing with consequences of scoliosis surgery on subjacent disc in term of volume and hydration properties.

Abstract
The aim of this study was to quantify from magnetic resonance imaging (MRI) the volume and hydration variation of the intervertebral disc in the lumbar spine before and after surgery in severe idiopathic scoliosis cases. MRI data were posttreated using a custom-made image processing software to semiautomatically derive volume properties of disc, annulus fibrosus and nucleus pulposus. The nucleus-disc volume ratio was also an indicator of the hydration level. The MRI that was performed in the clinical protocol concerned 28 patients with severe idiopathic scoliosis; four types of surgical instrumentations were used. The reliability of the three-dimensional reconstruction process was initially verified using an intraoperator reproducibility test. Original preoperative data on disc volume properties were then derived. Postoperative volume variations were quantified in discs below spine fusion, taking into account the level of arthrodesis and the disc location. It showed that the postoperative volume criteria increased significantly for nucleus, disc and nucleus-disc volume ratio and that some magnitude modulation could be conditioned by the location of surgical instrumentation. It tended to prove that the recovery of balanced physiological positioning and inherent biomechanical loads could induce a restored hydration of disc, which should favor the remodeling of free segments. This work was the first report to deal with the consequences of scoliosis surgery on subjacent disc in terms of volume and hydration properties. The clinical outcome will follow based on the patient cohort follow-up at 1 year after surgery.

STUDY DESIGN MRI study of pediatric Chance fracture. OBJECTIVE To evaluate bone and soft tissue lesions in pediatric Chance fracture. SUMMARY OF BACKGROUND DATA Several descriptions and classifications have been already developed for Chance fracture, but mainly for adult. Furthermore, they are all based only on radiographic studies. METHODS MRI and radiographs of 18 children with Chance fracture were analyzed before treatment. RESULTS On MRI, in all cases, no abnormal signs were noted on the intervertebral disc. Six patients had a bone fracture going through the pedicle and the vertebral body. Twelve patients had a physeal injury located on the superior or on the inferior vertebral endplate. Three types of lesions could be identified according to the location of the lesion in relation to the pedicle. CONCLUSION MRI is useful in the diagnosis of pediatric Chance fracture. It allows physeal injury to be clearly identified from disc injury.

Abstract
A 4-year-old child with multilevel spinal injury including atlantooccipital and atlantoaxial dislocation, and thoracic spinal fractures was managed nonoperatively with no significant sequelae from the cervical injuries, but persistent paraplegia from the associated thoracic spinal fractures. Although treatment guidelines cannot be established with the result of one case, we propose an algorithm for treatment of such a rare and severe situation.
