Straight Proximal Humeral Nailing Can Avoid Deltoid Atrophy for Proximal Humeral Fracture: A Comparison with Locking Plating

Abstract

Background: Open reduction and plate fixation are the main surgical treatment methods for proximal humeral fracture. However, it is difficult to avoid iatrogenic deltoid insertion injuries while ensuring a proper plate position. We aimed to compare the deltoid muscle volume in treating proximal humerus fractures using the locking compression plate (LCP) and intramedullary (IM) nail fixation methods. Methods
