Functional results after primary shoulder hemiarthroplasty for proximal humerus bone fractures

Shoulder hemiarthroplasty is one of the established methods for management of proximal humerus fractures particularly in the types with more displacement so that fixation is not possible. Successful treatment is a challenge for shoulder surgeons especially in elderly patients. The aim of this study is to investigate the functional results and prognostic factors on shoulder hemiarthroplasty. Thirty nine patients operated by one shoulder surgeon in Imam Khomeini and Shariati Hospital in Tehran, Iran, from October 2005 to February 2009 were included in this study and followed postoperatively for at least one year. Mean (±SD) age was 49.7±14.3 years
