Scoliosis IdiopathicSleep Disordered Breathing1 moreThis study aimed to investigate the prevalence and clinical significance of sleep-disordered breathing (SDB) in children with mild-moderate idiopathic scoliosis (IS).

Chronic Pain After Scoliosis and Thoracic Surgery in Children
Thoracic SurgeryScoliosis; Adolescence2 moreThe aim of this epidemiologic prospective study is to determine the prevalence of CPSP defined as pain occurring 4 months after scoliosis and thoracic surgery and rated > 3 on a 10 point visual analogue scale or FLACC scale, in children aged from 6 to 18 years. The main objective : prevalence of chronic post surgical pain 4 months after scoliosis ant thoracic surgery in children aged 6 to 18 years. The secondary objectives: the intensity of chronic post surgical pain, the prevalence of neuropathic syndrome and the predictive risk factors.

Prediction of 3D Effect of Brace in Idiopathic Scoliosis Treatment Using EOS Imaging System and...
Idiopathic ScoliosisIn this study, the accuracy of a new numerical method is evaluated for predicting the 3D effect of brace on idiopathic scoliosis. This method results from the combination of several innovative technologies: the EOS imaging system and the anatomical transfer developed by Anatoscope. This is an essential step in validating a digital tool that can be used in routine clinical practice.

Three-dimensional Effects of Bracing in Adolescent Idiopathic Scoliosis
Adolescent Idiopathic ScoliosisThis study intends to investigate the three dimensional (3D) effect of bracing on the adolescent idiopathic scoliosis (AIS). In particular, it will look at the relationship between frontal deformity correction and changes in the sagittal profile and apical vertebral rotation (AVR) during bracing. The investigators hypothesise that if the thoracic frontal deformity can be controlled with bracing, there will be spontaneous correction of the sagittal plane and rotation deformity through coupling.

Comparison of Dynamic Radiographs in Determining Fusion Level in Adolescent Idiopathic Scoliosis...
Adolescent Idiopathic ScoliosisThe purpose of this study is to identify the flexibility radiograph(s) that can most accurately predict the curve behaviour after surgical correction of AIS. With these findings, the investigators hope to give further guidance for the selection of fusion levels and to incorporate different dynamic radiographs into the Lenke Classification, leading to a more universal application that can consistently lead to good surgical and clinical outcome.

Cardiovascular Responses in Adolescent Idiopathic Scoliosis Girls
Adolescent Idiopathic ScoliosisThe aims of this pilot study are to determine the metabolic demand and exercise intensity level of E-Fit exercise intervention by evaluating the cardiovascular responses in AIS girls and whether the cardiovascular responses for AIS girls performing E-Fit will behave in the same way as compared to healthy controls. We hypothesise that 1) the metabolic demand and exercise intensity of E-Fit exercise intervention is equivalent to moderate-to-vigorous level; and 2) AIS girls have different cardiovascular responses as compared to healthy controls

MLX/XLX ACR Expandable Lumbar Interbody Implants
Degenerative Disc DiseaseSpondylolisthesis1 moreThe objective of this study is to evaluate the safety and performance of thoracic and/or lumbar spine surgery using the MLX and XLX ACR interbody implants as measured by reported complications, radiographic outcomes, and clinical patient outcomes. This study is being undertaken to identify possible residual risks and to clarify mid- to long-term clinical performance that may affect the benefit/risk ratios of the MLX and XLX ACR interbody implants.

Gait and Postural Stability Assessment in Children With Idiopathic Scoliosis Undergoing Posterior...
ScoliosisThe goal of this study is to evaluate children and adolescents with idiopathic scoliosis who are undergoing spinal fusion using motion analysis, balance, and outcome questionnaires. Little research has been done to evaluate how different fusion levels impact walking patterns, range of motion, posture and balance following spine instrumentation in children with idiopathic scoliosis. Debate still continues whether posterior spinal instrumentation with the last instrumented vertebra at or above Lumbar 3 (L3) will provide sufficient spine correction, greater motion, and better posture and balance when compared to a child with instrumentation at Lumbar 4 (L4). Furthermore, how does the spine fusion endpoint (last instrumented vertebra) impact quality of life, participation, and impairment in children and adolescents with idiopathic scoliosis and how do they compare to healthy age-matched peers. The goal of this study is to compare these two end points using gait analysis, postural stability, and outcome tools with the hopes of providing better clinical care to children with idiopathic scoliosis.

Anesthesia During Neurophysiologic Monitoring in Scoliosis Patients
Idiopathic ScoliosisWhen patients have spinal surgery, electrodes are placed on the body to measure motor evoked potentials (MEP) and somatosensory evoked potentials (SSEP). Many hospitals only use IV anesthesia because they feel that measuring MEP and SSEP is easier using IV anesthesia. At this hospital the investigators typically use inhaled anesthesia and are able to successfully measure MEP and SSEP. This is a study to find out if one method of anesthesia is better than the other for measuring MEP and SSEP.

Stereophotogrammetry of the Torso in Healthy Individuals and Patients With Scoliosis, Chest Wall...
Bone DiseasesObesity1 moreBackground: - Stereophotogrammetry (SP) uses four sets of digital cameras to generate a three-dimensional computer image. Unlike other types of evaluations which require radiation, SP only uses computer images to learn more about physical deformities such as scoliosis or about the placement of fat on the body. To refine the SP process, researchers are interested in collecting images and body data from individuals with skeletal structural problems such as scoliosis or chest wall deformities, individuals who are overweight or obese, and healthy volunteers. Objectives: - To use stereophotogrammetry to study different individual body types and refine existing imaging techniques. Eligibility: - Individuals at least 2 years of age who have spine, rib, or chest wall deformities; are overweight or obese (body mass index greater than 25); or are healthy volunteers. Design: Participants will be screened with a physical examination and medical history. The physical examination will include measurements of range of motion and joint mobility, torso width and length, and other observational data. Healthy volunteers and participants in the obesity group will also have bioelectric spectroscopy (bioimpedance), which uses an additional machine to measure how fat is spread in different parts of the body. After the physical examination has been completed, participants will have SP photographs taken. Participants will be asked to remove all clothing from the torso, stand with arms raised at the center of four cameras, and remain still while several images are taken. A complete image takes less than 1 second. Participants with spine or rib deformities, or who are in the obesity group, may also volunteer to return for followup SP imaging, once a year for 5 years, to study progress over time.
