A cadaveric radiographic analysis on the effect of extreme lateral interbody fusion cage placement with supplementary internal fixation on indirect spine decompression.
Cadaveric Biomechanical and Radiographic Analysis. ⋯ The radiographic results reported here using a cadaveric model add validity to the underlying rationale described for the minimally invasive lateral approach technique. Increases in disk height, foraminal and canal areas were not dependent on cage positioning within the disk space. As intraoperative placement of a cage in the central portion of the disk is an easier and safer technique, our results suggest that central placement may be preferable in a clinical setting.

Do lordotic Cages Provide Better Segmental Lordosis Versus Non-lordotic Cages in Lateral Lumbar Interbody Fusion (LLIF)?
Retrospective Comparative Radiographic Review. ⋯ Lordotic cages provided significant increase in operative level segmental lordosis compared to non-lordotic cages although overall lumbar lordosis remained unchanged. Anterior and posterior disc heights were significantly increased by both cages, providing basis for indirect spinal decompression.

Comparative Study Clinical TrialComparison of the clinical outcome in overweight or obese patients after minimally invasive versus open transforaminal lumbar interbody fusion.
This is a prospective single-center nonrandomized control clinical study involving 81 overweight or obese patients who underwent minimally invasive or open transforaminal lumbar interbody fusion (TLIF). ⋯ MiTLIF is a safe and reliable procedure for treatment of overweight or obese patients. The minimally invasive technique offers several potential advantages when compared with the open procedure. Although this technique needs a longer x-ray exposure time, it may still be a good option for overweight or obese patients.

Case ReportsPosterior hybrid technique for ossification of the posterior longitudinal ligament associated with segmental instability in the cervical spine.
Retrospective case series. ⋯ This hybrid posterior technique seems to be effective and safe in the treatment of selected patients with OPLL associated with segmental instability. The potential benefits of this technique include a stable environment for spinal cord recovery and prevention of progressive kyphosis and OPLL.

Surgical anatomy of the diaphragm in the anterolateral approach to the spine: a cadaveric study.
Laboratory cadaveric study. ⋯ An understanding of the diaphragmatic-costal and diaphragmatic-spinal attachments is key for the safe and effective implementation of diaphragm mobilization during the lateral and thoracoabdominal approaches to the spine.
