To determine if there is a difference in reoperation rates for symptomatic nonunions in atlantoaxial (C1-C2) fusions with or without bone morphogenetic protein (BMP) using data from a national spine registry and to analyze the different types of bone grafts used in the non-BMP group. ⋯ Using one of the largest retrospective studies on C1-C2 fusions with and without BMP, we found no difference in reoperation rates for symptomatic nonunions. For the non-BMP group, we found that lamina (+/- allograft) or allograft alone may also be just as effective as iliac crest graft (+/- allograft) in having no reoperations for symptomatic nonunions.

Intracranial arterial dissection (IAD) is a rare cerebrovascular disease that is likely underdiagnosed because of the inherent difficulty of visualizing the subtle radiographic signs of the pathologic small intracranial arteries. No widespread consensus exists on the treatment of IAD, and thus it is often managed empirically because of the absence of major randomized controlled trials. In this study, we conducted a systematic review to evaluate the management and treatment options for IAD. ⋯ Given these findings, clinicians should prescribe antiplatelet therapy for patients with IAD presenting with ischemia and consider endovascular treatment for those presenting with hemorrhage. However, further investigation is required given the heterogeneity of methods and reporting outcomes in the investigated studies.

Review Case Reports
Meckel's Cave Epidermoid Cyst Presenting as Multiple Cranial Nerve Deficits Due to Indirect Tumoral Compression of the Cavernous Sinus: A Case Report and Literature Review.
Epidermoid cysts in Meckel cave are exceedingly rare. Since 1971, only 17 cases have been reported in the literature, with most patients presenting with trigeminal hypesthesia. However, outgrowth of these lesions from Meckel cave can rarely lead to compression of the proximate cavernous sinus and the neurovascular structures contained within. To date, 2 cases have reported a Meckel cave epidermoid cyst presenting clinically as an intracavernous cranial nerve palsy, presumably a clinical manifestation of cavernous sinus compression from the lesion. ⋯ This is a unique report depicting an epidermoid cyst in the Meckel cave causing numerous cranial nerve deficits because of indirect tumoral compression of cranial nerves within the cavernous sinus.
