STUDY DESIGN: A retrospective study in Chinese Han people. PURPOSE: To explore whether promoter polymorphisms of matrix metalloproteinases-3 (MMP-3) (rs3025058) and interleukin-6(IL-6) (rs1800795) genes are associated to AIS gender bias. METHODS: A total of 200 patients (100 boys and 100 girls) with AIS and 200 healthy age-matched adolescents were recruited from July 2008 to August 2013 in our scoliosis center. All AIS patients had Cobb angles larger than 20°, average 43 ± 3...

BACKGROUND: Adolescent idiopathic scoliosis is a complex three-dimensional deformity of the spine characterized by deformities in the sagittal, coronal, and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe (coronal deformity, Cobb angle > 45°) adolescent idiopathic scoliosis curves. Understanding the anatomic difference in the pedicles of patients with adolescent idiopathic scoliosis is essential to reduce the risk of neurovascular or visceral injury through pedicle screw misplacement...

BACKGROUND: It is important to monitor how patients with juvenile and adolescent idiopathic scoliosis comply with their physiotherapeutic scoliosis-specific exercises (PSSE). Physiogame, a newly developed video game using the Game-Trak 3D interactive game controller, combines correct PSSE performance with gaming. It tracks the position of the working limb in 3D space during the exercises as participants aim to hit certain targets and avoid others, and gives direct feedback by stopping the game if the working limb leaves the target 3D space, which is chosen to secure the corrective position according to the Schroth method...

BACKGROUND AND OBJECTIVE: The aim of this study was to validate a new program which aims at measuring the three-dimensional length of the spine's midline based on two calibrated orthogonal radiographic images. The traditional uniplanar T1-S1 measurement method is not reflecting the actual three dimensional curvature of a scoliotic spine and is therefore not accurate. The Spinal Measurement Software (SMS) is an alternative to conveniently measure the true spine's length. METHODS: The validity, inter- and intra-observer variability and usability of the program were evaluated...

This study contrasts the ontogeny of the iliac crest apophysis using conventional radiography and multislice computed tomography (MSCT), providing probabilistic information for age estimation of modern Australian subadults. Retrospective abdominopelvic MSCT data acquired from 524 Australian individuals aged 7-25 and surveillance radiographs of adolescent idiopathic scoliosis patients included in the Paediatric Spine Research Group Progression Study (n = 531) were assessed. Ossification scoring of pseudo-radiographs and three-dimensional (3D) volume-rendered reconstructions using Risser (1958) quantitative descriptors indicate discrepancies in age estimates, stage allocation, and conflicting morphological progression...

BACKGROUND: Posterior spinal fusion to correct idiopathic scoliosis is associated with severe postoperative pain. Intrathecal morphine is commonly used for analgesia after adolescent posterior spinal fusion; however, anticipating and managing the increase in pain scores after resolution of analgesic effect of intrathecal morphine analgesia is challenging. In 2014, we developed a clinical protocol detailing both the administration of intrathecal morphine intraoperatively and the transition to routine, scheduled oral analgesics at 18 h postoperatively...

BACKGROUND: Blood loss and transfusion requirements during posterior spinal fusion for adolescent idiopathic scoliosis remain a concern. The mechanism of bleeding in these patients is poorly characterized. Thromboelastography is a comprehensive test of a patient's coagulation system commonly used in cardiac surgical procedures. It has not been well studied for use in patients with adolescent idiopathic scoliosis. METHODS: A prospective, observational study of the coagulation profile of patients with adolescent idiopathic scoliosis undergoing posterior spinal fusion is presented...

Adolescent idiopathic scoliosis is a 3D spinal deformity in frontal, sagittal and axial planes, with high relevance in the pediatric population especially in adolescents and females between 10 years of age and the end of growth spurt and skeletal maturity. The radiographic manifestation is a curve greater than 10° measured by Cobb method associated with vertebral rotation. "Idiopathic" diagnosis has to be done after neuroanatomical anomalies of the posterior cerebral fosa and spinal canal have been ruled out...

BACKGROUND: Guidelines suggest referral for scoliosis when rib slope (scoliometer measurement, angle of trunk rotation) is ≥7 degrees. We hypothesized that overweight and obese patients would have lower scoliometer measurements compared with normal-weight and underweight patients for a given spinal curvature, causing overweight and obese patients with adolescent idiopathic scoliosis to present for treatment later and with larger curves. Our goal was to determine the association between scoliometer readings and major curve magnitudes in relation to body mass index (BMI)...

BACKGROUND: Estimation of skeletal maturity, classically performed using Risser sign, plays a crucial role in the treatment of AIS. Recent data, however, has shown the simplified Tanner-Whitehouse (Sanders) classification, based on an anteriorposterior (AP) hand radiographs, to correlate more closely to the rapid growth phase and thus curve progression. This study evaluated the interobserver and intraobserver reliability of the Sanders and Risser classifications among clinicians at different levels of training...
