A vertebral artery arteriovenous fistula is rare and usually due to trauma. Atraumatic cases are quite rare. We reported 2 cases and a review of other reported studies. ⋯ Vascular changes are known in patients with neurofibromatosis. A proposed pathogenesis of fistula is that the fragility and defective nature of the arterial wall could be a predisposing factor or it might be congenital. Understanding the clinical symptoms, diagnosis, and effective management strategies are important for physicians treating patients with a vertebral artery arteriovenous fistula.

Although there are several surgical approaches for the treatment of tuberculum sellae (TS) meningiomas, clear indications for non-large TS meningiomas are still lacking. ⋯ The aim of surgery is maximal tumor resection without causing visual dysfunction. The classification proposed here may predict surgical risk associated with meningioma resection and further inform the selection of a surgical approach.

Accidental foreign body ingestion is a common occurrence; however, extraluminal migration is uncommon. We report for the first time in the literature an unusual migration of an ingested foreign body into the spinal canal through the vertebral body and discuss its possible route of migration. ⋯ Type, size, and shape of the foreign body determine the course of foreign body migration. A possible route of foreign body migration into the spinal canal is the Hahn canal and basivertebral foramina.

Sex has been known to significantly affect postoperative complications and length of stay after elective anterior cervical fusions. Current evidence on lumbar spine surgery is limited. ⋯ Contrary to literature on cervical fusions, we found that female sex was independently tied to an increased risk of adverse outcomes after elective posterior lumbar fusion. The results from the study suggest that women may benefit from close surveillance during the postoperative period to minimize risk of complications and subsequent resource utilization in this group.

The most commonly performed nerve transfers in upper trunk (UT) or partial brachial plexus injuries (BPIs) include the spinal accessory nerve to suprascapular nerve, Oberlin, and, lately, radial nerve (RN) (branch to triceps) to axillary nerve (AN) transfers. Routinely, the former 3 procedures are performed through an anterior approach (supraclavicular plus infraclavicular), while the triceps branch of the RN-AN transfer has been performed through a posterior approach with the patient in either the prone or semilateral position, which requires a separate incision in the posterior arm. The aim of the present study was to report the outcomes for 4 cases of quadruple nerve transfers performed for UT BPI using an all-anterior approach. ⋯ This technique appears to be feasible, with good-to-excellent outcomes achieved without requiring a separate posterior arm incision for the RN-AN transfer.
