In Situ M2 Bypass for Treatment of Fusiform Middle Cerebral Artery Bifurcation Aneurysm: Technical Case Instruction and Operative Video.

Background And Importance: Fusiform middle cerebral artery (MCA) bifurcation aneurysms can be challenging to treat with standard endovascular or microsurgical techniques. The in situ side-to-side bypass technique represents an elegant revascularization option for these aneurysms when trapping becomes necessary.

Clinical Presentation: A man in his 50s presented for evaluation of an incidentally found fusiform, 10 mm, right MCA bifurcation aneurysm with involvement of both the inferior and superior M2 trunks.

Segmental range-of-motion by vertebral level in fused and unfused patients with adolescent idiopathic scoliosis: a systematic review of the literature.

Purpose: This study aims to understand global and segmental spinal ROM in surgical and nonsurgical AIS patients.

Methods: This systematic review examined segmental vertebral ROM in AIS patients using PubMed, SPORTDiscus, MEDLINE, and Web of Science until October 8th, 2023. Inclusion criteria were articles on segmental motion in AIS patients, both operative and non-operative, under 18 years old.
