Surgery for the treatment of cervical spondylotic myelopathy is typically accompanied by complication rates between 11% and 38%. By determining clinical and surgical predictors of complications, clinicians can identify high-risk patients and plan accordingly. We conducted a survey of the AOSpine community to identify key predictors of postoperative complications. ⋯ This survey summarizes surgeons' perceptions of the most important clinical, imaging, and surgical risk factors for postoperative complications. Knowledge of these predictors allows clinicians to identify high-risk patients and institute prevention plans.

Fractional anisotropy (FA) of the high cervical cord (C1-C2), rostral to the injury site, correlates with upper limb function in patients with chronic cervical spinal cord injury (SCI). In acute cervical SCI, this relationship has not been investigated. The objective of this study was to identify functional correlates of FA of the high cervical cord in a series of patients with acute cervical SCI. ⋯ FA of the whole cervical cord as well as the CST, rostral to the injury site, is associated with preserved upper limb motor function as well as superior ASIA grades after acute cervical SCI. FA of the high cervical cord is a potential biomarker of neural injury after acute cervical SCI.

To present the clinical characteristics and prognostic factors of neurologic recovery in patients with cervical spinal tuberculosis (CST). ⋯ Surgery and Japanese Orthopaedic Association score before treatment are important predictors of neurologic recovery in patients with CST. A neurologic recovery curve could predict neurologic recovery in patients with CST and indicate in patients with neurologic deficit how long it will take to achieve complete neurologic recovery. The effect of surgery is quick, and the effect of conservative treatment is slower, but no difference in neurologic recovery was found in the long-term. Conservative treatment should be tried in every patient with CST with no obvious indication for surgery. In contrast to patients with tuberculosis without cervical spine involvement but with more complications, comprehensive conservative therapy should be preferred for patients with neurologic deficit to avoid unnecessary surgery and overtreatment and to conserve medical resources. Indications for surgical intervention for CST should be carefully selected.

Aneurysms of the posterior cerebral artery (PCA) are rare, and therefore the individual and institutional experience of their microsurgical management is usually limited. In the present article, we describe our experience with the subtemporal approach to aneurysms arising from the PCA. ⋯ The subtemporal approach is a suitable approach to aneurysms of the segments P1, P1-P2 junction, and P2, as well as the anterior P3 segment of the PCA. Using the subtemporal approach, the cerebrospinal fluid is released before retraction is necessary to prevent temporal lobe injury. The subtemporal approach can provide enough space for revascularization procedures. The most encountered complications were not related to the subtemporal approach but to the specific nature of PCA aneurysms.

To determine the rate and severity of in-hospital neurologic deterioration following vertebral fractures of spinal hyperostosis. ⋯ Neurologic deterioration during the initial hospitalization after spinal fractures in the setting of diffuse idiopathic skeletal hyperostosis or ankylosing spondylitis is common, and 1-year mortality is high.
