Spine

Multiphase cross-sectional survey of musculoskeletal pain. ⋯ Adjustment for pain at other sites enabled assessment of whether observed associations were with spinal pain itself or with the other sites of pain. Obesity is an important independent predictor of back pain and its severity. This has implications for primary prevention. The prevalence of spinal pain with disability continues to rise into old age. This has implications for healthcare planning.

This retrospective study was designed to analyze the results of 22 patients treated for postoperative soft tissue defects of the spine. ⋯ Flaps are a useful adjunct in the treatment of patients with complex spine wounds. Sliding paraspinal muscle flaps can effectively close wounds from the high cervical to the low lumbar area in one operative procedure. These patients can go on to successful spine fusion.

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.
