Posterior Vertebral Body Tethering: A Preliminary Study of a New Technique to Correct Lenke 5C Lumbar Curves in Adolescent Idiopathic Scoliosis.

Vertebral body tethering has been approved for adolescent scoliosis correction. The usual approach is anterior, which is relatively easy for the thoracic spine, but becomes much more challenging for the lumbar curves, with a higher rate of complications. The purpose of this study was to describe and evaluate the first results of a new posterior vertebral body tethering (PVBT) technique using pedicle screws through a posterolateral Wiltse approach.

Clinical and radiographic evolution of graduate patients treated with magnetically controlled growing rods: results of a French multicentre study of 90 patients.

Purpose: The purpose of this study was to investigate patients with early-onset scoliosis (EOS) who completed their electromagnetic lengthening rod program to assess the demographics of this population and to analyze the evolution of clinical and radiological parameters and the occurrence of complications.

Methods: This was a multicenter study with 10 French centers. We collected all patients with EOS who had undergone electromagnetic lengthening between 2011 and 2022.

Vertebral Body Tethering in AIS Management-A Preliminary Report.

Vertebral Body Tethering (VBT) is a recently developed surgical technique for the treatment of progressive and severe scoliosis in patients with significant growth potential. It has been used since the first exploratory series, which showed encouraging results on the progressive correction of the major curves. This study reports on a retrospective series of 85 patients extracted from a French cohort, with a follow-up at a minimum of two years after a VBT with recent screws-and-tether constructs.

Biomechanical and Clinical Comparative Study of the New Elastic Stable Intramedullary Nailing "MJ-FLEX Orthofix".

Background: The objectives of this study were first to compare the results of osteosynthesis with standard Metaizeau (MS) nails versus Metaizeau Junior Flex or MJF Orthofix (MJF) in terms of the stability of long-bone fractures in children, and to study the preoperative and postoperative safety of these new nails. We also carried out an analysis by computer modeling of a femur, in order to compare the biomechanical stability of the 2 nails. The interest in the MJF nails lies in the improvements they bring in terms of stability for long-bone fractures in pediatric patients, as well as the simplification of the surgical procedure.

New femoral derotation technique based on guided growth in children.

Derotation osteotomy is the only available treatment for medial femoral torsion in paediatric patients. To eliminate the need for postoperative immobilisation and to allow immediate weight bearing, we suggest a new technique that guides femoral growth. The goal is to convert part of the axial growth into rotation by placing a system composed of two screws and a cable around the distal femoral physis.

Update on leg fractures in paediatric patients.

Leg fractures are common and further increasing in prevalence in paediatric patients. The diagnosis is readily made in most cases. Choosing the best treatment is the main issue.

De novo 15q21.1q21.2 deletion identified through FBN1 MLPA and refined by 244K array-CGH in a female teenager with incomplete Marfan syndrome.

Interstitial deletions involving the 15q21.1 band are very rare. Only 4 of these cases have been studied using molecular cytogenetic techniques in order to confirm the deletion of the whole FBN1 gene.
