STUDY DESIGN Retrospective comparative study using radiographs and clinical findings. PURPOSE To test the hypothesis that asymmetric loading of immature spines in young athletes initiates scoliosis. OVERVIEW OF LITERATURE Scoliosis in athletes has been reported in the literature, but its causative factors have not been investigated. METHODS We compared the incidence, type and magnitude of...

OBJECTIVES To analyse the pathological substrate of human scoliotic spine during growth. MATERIAL AND METHODS We studied two spines obtained at the autopsy of two patients suffering from untreated scoliosis. Sample A (a girl of 13 years and 2 months) and sample B (a boy of 14 years and one month). On the conventional radiological study the curves were measured using the method of Cobb, and th...

BACKGROUND The main purpose of this research was to develop a new method for differentiating between scoliotic and healthy subjects by analysing the curvatures of their spines in the cranio-caudal view. METHODS The study included 247 subjects with physiological curvatures of the spine and 28 subjects with clinically confirmed scoliosis. The curvature of the spine was determined by a computer ...

An experimental computer program capable of reformatting stored display data from a CT scanner into true cross-sectional images of the spine has been clinically tested over a 1 year period. With this program, tomographic planes exactly parallel to the vertebral end plate can be imaged at the lumbosacral level even in patients who are markedly rotated or have scoliotic deformities. The reformatt...

STUDY DESIGN A retrospective study. PURPOSE To assess the radiographic progression of degenerative lumbar scoliosis after short segment decompression and fusion without deformity correction. OVERVIEW OF LITERATURE The aims of surgery in degenerative lumbar scoliosis are the relief of low back and leg pain along with a correction of the deformity. Short segment decompression and fusion can b...

A defect in the collagenous matrix of the intervertebral disc has been proposed as a contributory factor in the pathogenesis or progression, or both, ofthe scoliotic deformity. In an attempt to resolve these questions the collagen extractability and distribution across normal and scoliotic discs was investigated. The collagen content ofthe scoliotic nucleus pulposus was found to be higher than ...

Scoliosis causes deformations such as twisting and lateral bending of the spine. To correct scoliotic deformation, the extents of 3D spinal deformation need to be measured. This paper studies the modeling and measurement of scoliotic spine based on 3D curve model. Through modeling the spine as a 3D Cosserat rod, the 3D structure of a scoliotic spine can be recovered by obtaining the minimum pot...

STUDY DESIGN Retrospective. OBJECTIVE To evaluate the clinical safety and accuracy of the Tai Chi ((Equation is included in full-text article.)) technique for placing pedicle screws, without intraoperative radiographic imaging, in severe scoliotic spines. SUMMARY OF BACKGROUND DATA The current techniques for pedicle screw placement have a number of drawbacks in cases of severe scoliosis, in...

STUDY DESIGN A prospective study; 2-group design. OBJECTIVE This study aims to assess the time response of scoliotic spines to orthotic intervention using clinical ultrasound. SUMMARY OF BACKGROUND DATA Patients with moderate adolescent idiopathic scoliosis are generally advised orthotic treatment. However, the time to reach maximum correction after donning spinal orthosis or the time to re...
