We report the case of a 50 year-old woman with os odontoideum and posterior atlantoaxial subluxation, who underwent an occipitocervical fusion followed by endonasal endoscopic anterior decompression of the cervicomedullary junction (CMJ). ⋯ The endonasal endoscopic approach to the CMJ provides an effective and minimally invasive alternative for anterior decompression of irreducible CMJ pathology.

A prospective analysis. ⋯ In our study the first clinical assessment of a new bone mounted robot system guiding percutaneous pedicle screw placement was done. A deviation <2 mm to the surgeon 's plan in 91.0% to 98.5% verifies the system's accuracy.

Three case reports of patients with treatment of severe cervical hyperextension. ⋯ Patients with severe cervical hyperextension have high neurologic perioperative risk.

Case Reports
Vascular complications from anterior spine surgery in three patients with Ehlers-Danlos syndrome.
A case report of vascular complications arising from anterior spine surgery in 3 patients with Ehlers-Danlos syndrome (EDS). ⋯ These complications may be explained by the fragility of blood vessels secondary to the collagen defect in EDS. Though methods exist to decrease these complications, they may not be enough to prevent catastrophic bleeding. For EDS patients, risk of vascular complications during anterior surgery of the spine is high and surgeons should be aware of this when developing a surgical plan.

Reliability analysis based on expert panel case series review and grading per the Enneking and Weinstein-Boriani-Biagini classification systems. ⋯ Results indicate moderate interobserver reliability and substantial and near-perfect intraobserver reliability for both the Enneking and WBB classification in terms of staging and guidance for treatment, despite a less than moderate interobserver reliability in interpreting the Enneking local tumor extension and WBB sector. Before incorporating the classifications in the clinical practice and research studies, further work is required to investigate the validity of the classifications.
