Using current surgical methods, cranioplasty is associated with a high complication rate. We analyzed if there are preexisting medical conditions associated with complications and compared the effect of different implant materials on the degree of complications. ⋯ Based on these results, synthetic materials for cranial bone defect reconstruction exhibit more promising outcomes compared with autograft. There were differences in survival rates among synthetic materials.

Case Reports Comparative Study
Treatment and outcomes among 102 posterior inferior cerebellar artery aneurysms: a comparison of endovascular and microsurgical clip ligation.
The vicinity of brainstem and cranial nerves as well as the limited operative working space make clip ligation of posterior inferior cerebellar artery (PICA) aneurysms challenging. The small caliber of the PICA and the broad neck often associated with these aneurysms also create challenges in preserving this artery during treatment. Few data exist to compare the 2 treatment approaches for aneurysms in this location. ⋯ PICA aneurysms are challenging and require a multimodality treatment paradigm. Although microsurgery is associated with more short-term postoperative complications, presenting grade and patient's age remain the primary predictors of long-term outcome.

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.
