Reliability study of the computer-assisted SDSG (Spinal Deformity Study Group) classification of lumbosacral spondylolisthesis. ⋯ Substantial intra- and interobserver reliability was found for the computer-assisted SDSG classification, and all 6 types of lumbosacral spondylolisthesis were identified. Refinement of the computer-assisted classification technique is, however, needed to further increase the reliability of the SDSG classification and facilitate its clinical use.

An anatomic study of anterior cervical dissection of 11 embalmed cadavers. ⋯ This study found that superior to C7-T1, both RLNs had similar anatomic courses and received similar protection via surrounding soft-tissue structures. From an anatomic perspective, the authors did not appreciate a side-to-side difference superior to this level that could place either nerve under greater risk for injury.

Human cadaveric study. ⋯ Intraoperative O-arm images accurately detect significant pedicle screw violations in the thoracic and lumbosacral spine but are less accurate for the cervical spine.
-
Retrospective case series. ⋯ In this series, en bloc resection, the absence of metastasis, low-grade tumors, and negative margins were associated with improved overall survival. The aggressive use of sophisticated surgical and radiation techniques appears to confer an advantage to patients, decreasing local recurrence and increasing overall survival, even following incomplete surgical resection.

Retrospective case-control study. ⋯ Spinal fusion for scoliosis in RS can give a satisfactory technical result, but a high rate of early postoperative medical problems should be anticipated.
