TSA yielded pain relief, satisfaction for patients with post-traumatic osteonecrosis

Compared to hemiarthroplasty, total shoulder arthroplasty provided superior pain relief and patient-reported satisfaction among patients with post-traumatic osteonecrosis of the humeral head, according to study results.
Researchers performed 93 arthroplasties between 1973 and 2010 for post-traumatic osteonecrosis of the humeral head after conservative treatments failed. Researchers monitored 37 patients who underwent hemiarthroplasty and 46 patients who had a total shoulder arthroplasty for a minimum of 2 years of until reoperation.
Although results showed improved pain relief, elevation and external rotation for both hemiarthroplasty and total shoulder arthroplasty groups, patients in the total shoulder arthroplasty group had less pain at follow-up. Researchers also found better satisfaction (70% vs. 56%) and more excellent/satisfactory Neer ratings (57% vs. 41%) among patients who underwent total shoulder arthroplasty compared with hemiarthroplasty.

Reoperation occurred in nine patients in the hemiarthroplasty group and in five patients in the total should arthroplasty group, according to results, with painful glenoid arthrosis being the most common cause for reoperation in the hemiarthroplasty group and rotator cuff failure in total shoulder arthroplasty. Results showed an estimated 15-year survivorship of 79.5% for hemiarthroplasty and of 83% for total shoulder arthroplasty. – by Casey Tingle
