Abstract

Objective The aim of this work was to evaluate the results of use of cemented modular hemiarthroplasty prosthesis in cases of comminuted fractures of the proximal humerus. Background Proximal humeral fractures account for ∼5% of all joint fractures. More than 70% of patients with these fractures are older than 60 years of age, 75% are women and most of these fractures are related to osteoporosis. Shoulder hemiarthroplasty is a method of treatment of comminuted proximal humeral fractures in which complication of fracture fixation is avoided with a restoration of the anatomy of the shoulder joint. Materials and methods In the period between February 2012 and February 2016, a prospective study of 20 patients with post-traumatic comminuted fracture of the proximal humerus with or without dislocation of the humeral head had been admitted to El-Menoufia University Hospital. All cases that fulfilled the inclusion criteria had been treated with cemented modular hemiarthroplasty. Results The age of the patients in this study range from 30 to 75 years, 14 (70%) women and six (30%) men. The shoulder range of motion in two (10%) cases had an excellent result, eight (40%) cases had good results, seven (35%) cases had fair results, and three (15%) cases had poor results. Seventeen (85%) cases were satisfied with the results and three (15%) cases were not satisfied with the procedure. Conclusion Shoulder hemiarthroplasty is a method of treatment of comminuted proximal humeral fractures particularly in osteoporotic bone.
