Functional Outcomes and Complication Analysis of Plate Osteosynthesis versus Hemiarthroplasty in Three-part and Four-part Proximal Humerus Fractures.

Objective: To compare the functional results and complications of open reduction-internal fixation and hemiarthroplasty performed in Neer three-part and four-part proximal humerus fractures.

Methods: The retrospective study was conducted at the Istanbul Training and Research Hospital, Turkey, and comprised data of patients who were diagnosed with three-part or four-part fracture of the proximal humerus and underwent surgical procedure between January 2008 and April 2013. Those who had undergone open reduction-internal fixation using anatomical locking plates were placed in group A, and those who had undergone hemiarthroplasty were in group B.
