STUDY DESIGN: Case series. OBJECTIVE: We investigated the contributions of rod contouring and of differential rod contouring (DRC) to the reduction of apical axial vertebral body rotation in patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: DRC is used for posterior spinal correction and fusion. The contribution of DRC to vertebral body derotation is unclear. METHODS: We analyzed the results of intraoperative computed tomography (CT) in 40 consecutive AIS patients with thoracic curves (Lenke type I or II, 35; type III or IV, 5)...

BACKGROUND: It is generally recognized that the main thoracic curve Cobb angle threshold for surgical correction is approximately 50 degrees in patients with adolescent idiopathic scoliosis (AIS). Although AIS with a Cobb angle of <50 degrees is sometimes treated surgically to improve cosmesis, the precise outcomes are unclear. This study analyzed the postoperative results for AIS with a main thoracic curve of 50 degrees. METHODS: Thirty-nine consecutive patients with Lenke type 1-2 curves underwent posterior spinal fusion for AIS...

BACKGROUND: The standard for evaluating scoliosis is PA radiographs using Cobb angle to measure curve magnitude. Newer PACS systems allow easier Cobb angle calculations, but have not improved inter/intra observer precision of measurement. Cobb angle and its progression are important to determine treatment; therefore, angle variability is not optimal. This study seeks to demonstrate that a performance equivalent to that achieved in the manual method is possible using a novel computer algorithm with limited user input...

A small vertebral cross-sectional area (CSA) imparts a mechanical disadvantage that escalates the risk for vertebral fractures in elderly populations. We examined whether a small vertebral CSA is also associated with a greater degree of vertebral wedging in children. Measurements of vertebral CSA, lumbar lordosis (LL) or thoracic scoliosis angle and vertebral wedging were obtained in 100 healthy adolescents (50 boys and 50 girls) and 25 girls with adolescent idiopathic scoliosis (AIS) using magnetic resonance imaging...

Does scoliosis severity increase scoliosis risk or severity in relatives? In a cohort of 1257 severe idiopathic scoliosis patients, the percentage with at least one affected relative was compared across the categories of patient sex, major curve severity (Cobb angle), and treatment method. In total, 138 (11%) of 1257 patients had at least one affected first-degree relative and 59 (5%) had at least one affected second-degree relative. As expected, males were more likely to have affected first-degree relatives than females (18 vs...
