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.

A biomechanical cadaveric study of a modified U-shaped interspinous distraction device.
An experimental study. ⋯ The modified version of a U-shape IDD is effective in stabilizing an unstable segment of the lumbar spine. The device does not create deleterious effects on the adjacent vertebrae.

Height restoration and preservation in osteoporotic vertebral compression fractures: a biomechanical analysis of standard balloon kyphoplasty versus radiofrequency kyphoplasty in a cadaveric model.
Biomechanical cadaver study. ⋯ On the basis of our results, the unipedicular RFK in osteoporotic compression fractures might represent a promising alternative for the clinical setting.
