Cadaveric specimens were measured to determine appropriate placement for C1 lateral mass screws. Instrumentation guidelines were developed and used to instrument a series of cadaveric specimens. Clinical experience with C1 lateral mass fixation was reviewed to evaluate results. Postoperative computed tomographic (CT) scans were reviewed to evaluate screw placement. ⋯ C1 lateral mass fixation is a safe alternative for upper cervical fixation with several potential advantages versus other techniques, but further clinical evaluation is warranted.

Fracture-related thoracic kyphotic deformity correction by single-stage posterolateral vertebrectomy with circumferential reconstruction and stabilization: Outcomes in 30 cases.
This paper is a retrospective chart review. ⋯ Thoracic kyphotic correction is possible through a prone single-stage simultaneous anterior vertebrectomy and posterior reconstruction. Sufficient anterior and posterior correction of instability and fracture using the SUMC technique is possible with similar results to the traditional 2-stage approach.

Biomechanical assessment of minimally invasive decompression for lumbar spinal canal stenosis: a cadaver study.
A biomechanical study on the cadaveric human lumbar spine. ⋯ These results go toward supporting a minimally invasive bilateral decompression. Minimally invasive bilateral decompression, as opposed to a conventional medial facetectomy, preserves the facet joints as much as possible. Preserving the facet joints during the decompression should produce less postoperative instability.
