A retrospective study was carried out using Shen instrumentation, which is a modified pedicle rod sleeve spinal system, to perform reduction and fusion in patients with unstable thoracolumbar fracture. ⋯ Based on the understanding of biomechanics and the present clinical results, Shen instrumentation is as efficacious as conventional devices available today and may serve as a cost-effective option for thoracolumbar injuries, especially in a developing country.

A prospective evaluation of adolescent idiopathic scoliosis patients undergoing operative treatment on the Orthopedic Systems Incorporated (OSI; Jackson) frame. ⋯ Performing adolescent idiopathic scoliosis correction on the OSI frame tends to decrease thoracic kyphosis, increase thoracolumbar lordosis, and increase segmental instrumented lumbar lordosis, while it maintains total lumbar lordosis.

This was a retrospective study of 500 patients undergoing corrective surgery between 1987 and 1997 for spinal deformity caused by idiopathic scoliosis. ⋯ Combined somatosensory-evoked and neurogenic motor-evoked potentials monitoring during idiopathic scoliosis surgery represents a standard of care that obviates the need for an intraoperative wake-up test when reliable data are obtained and maintained.

A nonrandomized descriptive case series. ⋯ To avoid late progression of trunk deformity in skeletally immature patients, anterior spinal release and fusion combined with posterior segmental spinal instrumentation and fusion from the upper thoracic spine to the pelvis are recommended. Skeletally mature patients with good curve flexibility can be treated with posterior instrumentation and fusion only. Skeletally mature patients with large fixed curves benefit from an anterior-posterior procedure for better correction of the scoliosis and pelvis obliquity. Despite the surgical complexity and expected complications, the overall good surgical results and high patient and caregiver satisfaction confirm that corrective spinal surgery is indicated and is beneficial for most patients with total-body-involvement cerebral palsy and scoliosis.

A 3-week tour of the Far East was coordinated by Dr. Ronald DeWald, senior travelling fellow appointed by the Scoliosis Research Society. Three junior fellows appointed by the Education Committee of the Scoliosis Research Society accompanied him. The purpose of this fellowship was to develop a comaraderie and exchange ideas, thoughts, and experiences in the field of spinal deformity.
