This study aimed to analyze the effect of patient positions on the lordosis and scoliosis of patients with degenerative lumbar scoliosis (DLS).Seventy-seven patients with DLS were retrospectively analyzed. We measured lordosis and Cobb's angle on preoperative upright x-rays and magnetic resonance imagings in supine position. The lordosis and scoliosis of surgical segments in intraoperative prone position were measured on intraoperative radiographs of 20 patients to compare with that in standing position. Paired t tests were performed to investigate the parameters of the sample...

BACKGROUND: Spinal muscular atrophy (SMA) is a progressive neuromuscular disease commonly including progressive scoliosis resulting in severe deformity and negatively affecting pulmonary function. Surgical correction and stabilization of this progressive deformity is generally recommended; however, the timing and method of surgical fixation remains controversial. METHODS: Retrospective review of clinical, radiographic, and pulmonary function data from 16 children with SMA and surgically treated scoliosis between 1985 and 2013...

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...

STUDY DESIGN: This is a case-control study. OBJECTIVE: The present study aimed to compare the cross-sectional areas of the psoas major and multifidus muscles between elderly patients with adult spinal deformity (ASD) and age-matched and body weight-matched controls, and to evaluate the associations between the cross-sectional areas of these muscles and the severity of spinal deformity. SUMMARY OF BACKGROUND DATA: The study included 49 female kyphosis patients with mild scoliosis (Cobb angle <20 degrees; mean age, 70...

PURPOSE: To investigate the contribution of radiation therapy to acute and late toxicity in pediatric chest wall sarcoma patients and evaluate dosimetric correlates of higher incidence toxicities such as scoliosis and pneumonitis. METHODS AND MATERIALS: The data from 23 consecutively treated pediatric patients with chest wall sarcomas of various histologies (desmoid, Ewing, rhabdomyosarcoma, nonrhabdomyosarcoma-soft tissue sarcomas) were reviewed to evaluate the relationship between end-organ radiation dose, clinical factors, and the risk of subsequent late effects (scoliosis, pneumonitis)...

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...

BACKGROUND CONTEXT: The efficacy of one-stage posterior pedicle screw instrument used in the treatment of non-dystrophic scoliosis in neurofibromatosis type I (NF-1) is unknown. Also, there is no study that has directly compared the results of spinal deformity correction between non-dystrophic scoliosis in NF-1 and adolescent idiopathic scoliosis (AIS). PURPOSE: The objectives of this study were to study the efficacy of a one-stage posterior pedicle screw instrument used in the treatment of non-dystrophic scoliosis in NF-1 and to compare non-dystrophic scoliosis in NF-1 with matched AIS to illustrate the differences...

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...

STUDY DESIGN: Retrospective clinical cohort study. OBJECTIVE: To determine if certain risk factors (age, curve magnitude, skeletal maturity, gender, and curve pattern) traditionally associated with curve progression and surgical intervention in the general population apply equally to African Americans. SUMMARY OF BACKGROUND DATA: Currently, information is limited on the role that a patient's race plays in the risk of curve progression of adolescent idiopathic scoliosis (AIS), and existing studies have conflicting results...

Idiopathic scoliosis (IS) is the most common 3-dimensional deformation abnormality of the spine with direct effects on the thoracic cage and can potentially affect respiratory function.The purpose of the present study was to recognize whether the 3-dimensional displacement of the spine and trunk as a consequence of IS directly influences and diminishes respiratory function in children with mild IS.The study involved 68 children aged 10 to 12 years with mild thoracic or thoracolumbar IS who were the outpatients of the local Center for Corrective Gymnastics...

INTRODUCTION: Recent developments of spinal instruments allow to address nearly all components of idiopathic scoliosis. Direct vertebral rotation (DVR) maneuver was introduced to correct apical axial vertebral rotation. It is however still not well established how efficiently DVR affects results of scoliosis correction. The object of the study was to evaluate en bloc apical vertebral rotation (DVR) and its impact on coronal and sagittal correction of the spine in patients undergoing surgical scoliosis treatment...

STUDY DESIGN: A prospective observational study. OBJECTIVE: To evaluate whether scoliosis is a risk factor for gastroesophageal reflux disease (GERD) in elderly patients. SUMMARY OF BACKGROUND DATA: Sagittal spinal deformities are reported to cause GERD, but its association with spinal deformity in the coronal plane is not well studied. METHODS: We examined 190 patients with spinal disorders (mean age 70.6±8.6 y) who underwent standing whole-spine x-rays in the coronal and sagittal planes...

STUDY DESIGN: Prospective study. OBJECTIVE: To investigate the safety, outcome, and strategy of the 1-stage interrupted 2-level transpedicular wedge osteotomy for correcting the severe kyphotic deformity in ankylosing spondylitis (AS). SUMMARY OF BACKGROUND DATA: There has been a large series in the literature reporting on results of osteotomy for the correction of kyphotic deformity secondary to AS. However, few articles have reported, in detail, the plan, design, strategy, and effect of 1-stage interrupted 2-level transpedicular wedge osteotomy for the correction of severe kyphotic deformity in AS...

STUDY DESIGN: A retrospective review of data collected prospectively. OBJECTIVE: The study aimed to assess the possible effects of idiopathic scoliosis on left ventricular (LV) myocardial performance in children and adolescent patients. SUMMARY OF BACKGROUND DATA: Spine anomaly may impair cardiorespiratory function. It has been confirmed that respiratory function decreased in patients with scoliosis. However, limited study of the effect of scoliosis on heart function has been published, and no assessment of myocardial deformation of these patients has been reported to our knowledge...
