BACKGROUND The selection of fusion levels continues to be controversial in adolescent idiopathic scoliosis (AIS). The classifications of King and Lenke remain the most widely used, but recent studies have demonstrated their shortcomings, including poor interobserver reproducibility. We propose a method of preoperative planning that is independent of(More)
STUDY DESIGN Retrospective study of prospectively collected data. OBJECTIVE Compare Universal Clamps (UCs) and hooks for the thoracic correction of adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA In scoliosis surgery, sagittal correction is as important as frontal correction due to the risk of junctional kyphosis. Compared to all-screw(More)
EOS imaging system is accessible to clinicians since 2007, allowing 3D spinal reconstructions in a functional standing position with reduced radiation. However, numerous ongoing research protocols continuously help implementing the dedicated software. The main principle and applications of the EOS device are discussed here, with an emphasis on future(More)
STUDY DESIGN Outcome study to determine the internal consistency, reproducibility, and concurrent validity of the French-Canadian version of the Scoliosis Research Society 22 (SRS-22 fcv) patient questionnaire in France. OBJECTIVE To determine whether the SRS-22 fcv can be used in a population from France. SUMMARY OF BACKGROUND DATA The SRS-22 has been(More)
STUDY DESIGN A reproducibility study was conducted in preoperative and postoperative three-dimensional (3D) measurements for patients operated for adolescent idiopathic scoliosis (AIS). OBJECTIVE To assess the reliability of preoperative and postoperative 3D reconstructions using EOS in patients operated for AIS. SUMMARY OF BACKGROUND DATA No prior(More)
INTRODUCTION Lower limb torsion varies substantially among healthy children during growth. Values reported in the literature to date have been obtained using semi-quantitative clinical or 2D measurement methods. Quantitative 3D measurement would help determine the physiological range of lower limb torsion. Low-dose stereoradiography with 3D reconstruction(More)
Fresh frozen spine specimens are commonly used in biomechanical investigations of the spine. Since many study designs require staged preparation and testing, the effect of multiple freeze-thaw cycles on motion behavior should be understood. The objective of this study was to investigate the effect of multiple freeze-thaw cycles on the biomechanical(More)
Kingella kingae arthritis in children is now mainly diagnosed by PCR, which has surpassed conventional culture of joint fluid. As oropharynx colonization is the first step of Kingella kingae invasion, we prospectively investigated the possibility of cultivating it from throat swabs, in children hospitalized for K. kingae arthritis. Throat culture was(More)
Pelvic incidence was described as a fundamental parameter to describe spino–pelvic balance. In high-grade spondylolisthesis, severe dystrophic changes of the upper sacral endplate may be responsible for technical difficulties in pelvic incidence measurement. We propose to evaluate the reliability of PI measurement in high-grade spondylolisthesis patients(More)
Percutaneous epiphysiodesis using transphyseal screws (PETS) has been developed for the treatment of lower limb discrepancies with the aim of replacing traditional open procedures. The goal of this study was to evaluate its efficacy and safety at skeletal maturity. A total of 45 consecutive patients with a mean skeletal age of 12.7 years (8.5 to 15) were(More)
