Osteogenesis imperfecta (OI) is a hereditary connective tissue disorder that leads to bone weakness and deformities, especially in the spine, which can lead to poor outcomes.The aim of this study was to find patterns and risk factors in spinal deformities in patients with OI.In a retrospective study, 70 patients with OI were selected. Radiographs of the spine were evaluated. We observed the pre...

Method The first concept is the mathematical model of circled helicoid. In the torso column, the generating circle is perpendicular to the axis. To obtain a torso column in the opposite side of scoliosis, the superposition of three electronic instantaneous full 3D moldings are necessary: First molding in self active axial elongation for pelvis and shoulders Second molding in lumbar shift and ph...

Abstract Background Thoracic scoliosis has been shown to be associated with hypokyphosis in adolescent idiopathic (AIS). However, the relationship of sagittal spino-pelvic parameters different coronal curve patterns and their influence on patient-perceived quality life is unknown. This study aims determine association between malalignment patients AIS effects SRS-22r scores. Methods A cross-sec...

Study design This was a multicentric cross-sectional descriptive study. Objective To analyze patterns of 3D rib cage deformity in subjects with adolescent idiopathic scoliosis (AIS) and their relationship the spinal deformity. Summary background data Subjects AIS present that can affect respiratory functions. The deformities to are still unelucidated. Methods A total 200 71 controls underwent l...

BACKGROUND Vertebral wedging is associated with spinal deformity progression in adolescent idiopathic scoliosis. Reporting frontal and sagittal wedging separately could be misleading since these are projected values of a single three-dimensional deformation of the vertebral body. The objectives of this study were to determine if three-dimensional vertebral body wedging is present in mild scolio...

PURPOSE The purpose of this study was to identify the influence of pelvic incidence (PI) on spinopelvic parameters in patients with degenerative lumbar scoliosis (DLS) and compare them with those of a normal population. METHODS There were two groups in this study. One group was composed by 136 patients with DLS and another was composed by 120 participants free of spinal disease. In each group...

BACKGROUND Some patients with mild or moderate thoracic scoliosis (Cobb angle <50-60 degrees) suffer disproportionate impairment of pulmonary function associated with deformities in the sagittal plane and reduced flexibility of the spine and chest cage. Long-term improvement in the clinical signs and symptoms of childhood onset scoliosis in an adult, without surgical intervention, has not been ...

PURPOSE Spinal deformity in neurofibromatosis, when associated with dystrophic change, is a major treatment challenge. Early anterior and posterior spinal fusion is the accepted treatment plan for severe progressive kyphoscoliosis. Resection of the vertebral body as an additional step in correction and fusion has not been previously investigated. Information on the functional status of the neur...

BACKGROUND Previous research has suggested a correlation between pulmonary impairment and thoracic spinal deformity. The curve magnitude, number of involved vertebrae, curve location, and decrease in thoracic kyphosis independently contribute to pulmonary impairment, but the strength of these associations has been variable. The objectives of this study were to test the hypothesis that increased...
