Abstract

Purpose.  To evaluate early functional outcomes of primary hemiarthroplasty for 4-part proximal humeral fractures with or without dislocation. 

Patients and Methods: This prospective study was conducted on 20 patients in the Department of Orthopaedics, GMC, Srinagar. 15 men and 5 women aged 40 to 72 (mean, 55.4) years underwent hemiarthroplasty from August 2016 to August 2018, for 4-part proximal humeral fractures with or without dislocation. All the patients reported normal shoulder function prior to injury. The range of shoulder motion and muscle power were evaluated, as were subjective pain and satisfaction (using the UCLA scoring system).

Results: At the final follow-up, the mean maximum abduction was 139.5o   and the mean maximum forward flexion was 145.6º. All patients had radiographic union of the tuberosities except two (one had resorption of GT and one had proximal migration of GT, both had poor results). The mean UCLA score was 28; 14 patients attained good-to-excellent scores, whereas 6 attained lower (fair-to-poor) scores. The mean UCLA score was higher in patients aged <60 (n=13) than those who were older (n=7) [30 vs 24, p=0.07]. Majority of the patients had complete relief of pain and were satisfied with the procedure.
