Study: Surgeons may consider RTSA for the treatment of avascular necrosis

For patients with avascular necrosis of the humeral head, reverse total shoulder arthroplasty resulted in similar patient-reported outcomes compared with anatomic total shoulder arthroplasty, published results showed.
Using data from a multinational shoulder arthroplasty database, Richard McLaughlin, MD, of the department of orthopaedics and sports medicine at the University of Washington in Seattle, and colleagues performed a retrospective review of 67 reverse total shoulder arthroplasty (RTSA) procedures and 52 anatomic total shoulder arthroplasty (aTSA) procedures in patients with a preoperative diagnosis of avascular necrosis (AVN) of the humeral head. According to the study, range of motion (ROM) and patient reported outcome measures (PROMs) were preoperatively and postoperatively compared between the cohorts.
Researchers found RTSA “demonstrated significant improvements” in ROM and PROMs. The RTSA cohort demonstrated greater improvement in abduction, while the aTSA cohort demonstrated greater improvement in internal rotation. McLaughlin and colleagues also noted postoperative University of California Los Angeles scores and VAS pain scores were better after RTSA compared with aTSA.
“Both RTSA and aTSA provide excellent surgical options to improve pain and function for humeral head AVN with an acceptable complication profile,” McLaughlin and colleagues wrote in the study.
“RTSA provides comparable improvements in pain and outcome scores to aTSA in patients with AVN when clinical factors preclude placement of an aTSA,” they added.
