A biomechanical human cadaveric study. ⋯ Destabilization of both the facet complex and disc was required to achieve anterior listhesis of 3.1 mm consistent with a grade 1 DLS under an applied shear force of 250 N. Sufficient listhesis was measured without radical specimen resection. Important anatomical structures for supporting spinal instrumentation were preserved such that this model can be used in future to characterize behavior of novel instrumentation prior to clinical trials.
-
Clinical study. ⋯ The endoscopic transoral approach may be a more direct route to C1 and the odontoid than the endoscopic endonasal approach. This approach allows complete resection odontoid to decompress the cervicomedullary junction without increasing the risk of complications such as wound infection, meningitis, and velopharyngeal insufficiency. Usually, the occipitocervical posterior fusion and tracheotomy is less necessary in this approach.

A radiographical follow-up and analysis. ⋯ 2.

Cross-sectional, questionnaire study. ⋯ Findings highlight extreme variability in practice associated with a notable lack of standard of care and provide a baseline for utility studies that may lead to more evidence-driven care.
