BACKGROUND: Pelvic incidence increases gradually throughout growth until skeletal maturity. Growing rod instrumentation has been suggested to have a stabilizing effect on the development of the normal sagittal spinal alignment. The purpose of this study is to determine the effect of fixed sagittal plane caused by dual growing rod instrumentation on the natural progression of sagittal spinopelvic parameters in children with idiopathic or idiopathic-like early onset scoliosis. METHODS: Hospital records of children with growing rod instrumentation from 4 separate institutions were reviewed retrospectively...

BACKGROUND: Sagittal balance restoration has been shown to be an important determinant of outcomes in corrective surgery for degenerative scoliosis. Lateral interbody fusion (LIF) is a less-invasive technique which permits the placement of a high lordosis interbody cage without risks associated with traditional anterior or transforaminal interbody techniques. Studies have shown improvement in lumbar lordosis following LIF, but only one other study has assessed sagittal balance in this population...

PURPOSE: Utilizing 2D measurements, previous studies have found that in AIS, increased thoracic Cobb and decreased thoracic kyphosis contribute to pulmonary dysfunction. Recent technology has improved our ability to measure and understand the true 3D deformity in AIS. The purpose of this study was to evaluate which 3D radiographic measures predict pulmonary dysfunction. METHODS: One hundred and sixty-three surgically treated AIS patients with preoperative PFTs (FEV, FVC, TLC) and EOS(®) imaging were identified at a single center...

PURPOSE: Recently introduced cobalt-chromium (CoCr) rods that rely solely on pedicle screws produce very good results in correcting scoliotic curves. All-pedicle screws constructs are also suspected of decreasing thoracic kyphosis. The current study was designed to evaluate sagittal correction in adolescent idiopathic scoliosis patients, using 6-mm CoCr rods and all-screw constructs. MATERIALS AND METHODS: A total of 61 patients treated by posterior spinal fusion and instrumentation, using all-pedicle screw constructs were included...

BACKGROUND CONTEXT: Deformity progression after posterior fusion in skeletally immature patients with scoliosis has remained a topic of debate. It occurs when the anterior segment of the apical zone continues to grow after successful posterior fusion, resulting in progressive bending and rotation of the vertebral bodies. For this reason, circumferential fusion using a combined anterior-posterior approach has been used to prevent this occurrence. PURPOSE: The aim of this study was to report instrumented spinal fusion with convex hemi-interbody arthrodesis using a posterior-only approach in Risser stage 0 or 1 scoliosis patients...

STUDY DESIGN: A retrospective study to determine whether brace treatment is appropriate for adolescent idiopathic scoliosis(AIS) patients with Cobb angle between 40 and 50 degrees who utterly refuse surgery. OBJECTIVE: To investigate whether it is possible to halt the curve progression of AIS patients with Cobb angle between 40 and 50 degrees through bracing, and to identify factors that could influence the effectiveness of brace treatment in such patients. SUMMARY OF BACKGROUND DATA: Despite of the great achievements in treating patients with mild curve, bracing has been considered to be inappropriate for those with curves more than 40 degrees...

PURPOSE: Although adolescent idiopathic scoliosis (AIS) is known to impact the 3D orientation of the spine and pelvis, the impact of the vertebral position relative to the X-ray scanner on the agreement between 2D and 3D measurements of a curve has not been evaluated. The purpose of this study was to investigate the agreement between 2D and 3D measurements of the scoliotic curve as a function of the 3D spinal parameters in AIS. METHODS: Three independent observers measured the thoracic and lumbar Cobb angles, Kyphosis, and lordosis on the posterior-anterior and lateral X-rays of AIS patients...
