Hemiarthroplasty for nontraumatic avascular necrosis of the humeral head is associated with low complications and reoperation rates

Hemiarthroplasty versus total shoulder arthroplasty in B2 glenoids with an intact rotator cuff: a long-term matched cohort analysis

“…While our study focused on primary glenohumeral OA as an indication for shoulder arthroplasty, several recent studies have demonstrated favorable outcomes for HA when performed for avascular necrosis of the humeral head. 5 , 32 The investigation by Cheema et al reported a complication rate of 4% and revision rate of 3% for these patients at mean 6 years of follow-up. Additionally, only 2% of patients had severe postoperative humeral head subluxation and 7% had severe glenoid erosion.…”

“…Additionally, only 2% of patients had severe postoperative humeral head subluxation and 7% had severe glenoid erosion. 5 Similarly, Wang et al reported a more than 80% survivorship for 16 shoulders undergoing either HA or TSA at 10 years postoperatively. 32 They also demonstrated similar improvements in pain and function between HA and TSA.…”
