Hemiarthroplasty, TSA yielded pain relief for patients with atraumatic osteonecrosis
Patients with atraumatic osteonecrosis of the humeral head experienced lasting pain relief and improved range of motion after undergoing either hemiarthroplasty or total shoulder arthroplasty, according to results.
The study included 141 shoulder arthroplasties performed in patients with atraumatic osteonecrosis of the humeral head. Of these, investigators followed 67 hemiarthroplasties and 71 total shoulder arthroplasties (TSAs) for at least 2 years or until reoperation. Researchers considered imaging-confirmed osteonecrosis and failure to respond to conservative treatment modalities as an indication for surgery.
