Retrospective radiograph and chart review of 28 patients with adult idiopathic scoliosis undergoing primary corrective surgery. Clinical and radiographic parameters were assessed before surgery, after surgery, and at a 2-year follow-up assessment. A self-perceived outcome questionnaire was administered to the study patients at a minimum 2-year follow-up assessment. ⋯ Surgery for adult idiopathic scoliosis using third-generation instrumentation techniques provides significant clinical improvement, scoliosis correction, maintenance of sagittal alignment, and patient satisfaction, with an acceptable complication rate.

A case report of distant discitis and vertebral osteomyelitis involving skip levels after caudal epidural steroid injection. ⋯ Distant discitis and vertebral osteomyelitis involving skip levels and without the occurrence of epidural abscess formation is a serious but rare complication after epidural injection.
-
A retrospective clinical study was conducted. ⋯ Posterior decompression and partial reduction followed by circumferential stabilization performed in one stage combining pedicle fixation with trans-sacral titanium cage interbody fusion is an effective and safe technique for the management of severe spondylolisthesis.

Using a validated finite element model, the biomechanical effects of pars defect in a lumbar segment with and without different degrees of slip (up to 50% slip) were studied. ⋯ The stiffness of a spondylolisthetic motion segment decreases as the slip increases. Lateral bending and torsion are moment directions causing the greatest resulting motions.
