Well-Performing Locking Plate Fixation with Calcar Screws Technique in Three-Part Proximal Humorous Fracture: Educational Corner

Background: proximal humerus fracture (phf) has an increasing incidence rate in older people falling on their stretched arms (1). because of the vascular anatomy pattern of the proximal humerus, support of the medial cortex becomes essential (2). according to the recent studies, different strategies can provide medial support, but locking plate fixation is the most widely used technique (3). however, 30% of reoperation is reported due to fixation failure, avascular necrosis (avn) of the humeral head, and postoperative infections. these complications are because of a lack of medial column appropriate structural support (4-6).
