Comparative StudyComparison of posterolateral fusion with and without additional posterior lumbar interbody fusion for degenerative lumbar spondylolisthesis.
The surgical approach that should be used for degenerative spondylolisthesis (DS) is a controversial issue. Decompression and posterolateral fusion (PLF) with or without lumbar interbody fusion is widely used. Many studies have compared the outcomes of these 2 approaches, but the appropriate indications for these approaches are still unclear. The authors retrospectively studied the effects of posterior lumbar interbody fusion (PLIF) after PLF for the treatment of DS. ⋯ This study suggests that preoperative segmental instability may be a criterion determining whether an additional PLIF would be beneficial in the treatment of lumbar DS.

Cervical spine motion in manual versus Jackson table turning methods in a cadaveric global instability model.
A study of spine biomechanics in a cadaver model. ⋯ The data suggest that the manual transfer technique produces 2 to 3 times more cervical spine angular motion than the Jackson table method of transfer. The use of a collar provides significant benefit in limiting spine motion that is only observed in axial rotation. Choice of headrest does have a significant effect on the amount of motion allowed during turning, with the Foam Pillow and Prone View generally providing more effective stabilization compared with the Mayfield.
