Abstract:Avascular necrosis (AVN) may occur in up to 77% of proximal humeral fractures and can cause fixation failure. Risk factors include fracture position, calcar length and medial hinge integrity. We routinely perform intra-articular biceps tenotomy with tenodesis at the level of pectoralis major to facilitate fragment identification and potentially ameliorate post-operative pain relief. Concern exists that tenotomising the biceps damages the adjacent arcuate artery, potentially increasing the rate of AVN. The purp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
