Study: RSA may be associated with increased risk of complication compared to ASA.

Data from a study published online in the Journal of Shoulder and Elbow Surgery suggest that reverse shoulder arthroplasty (RSA) may be an independent risk factor for inpatient morbidity, mortality, and increased hospital costs compared with anatomic shoulder arthroplasty (ASA). The authors drew data on 51,052 patients from the Nationwide Inpatient Sample database who underwent either anatomic total shoulder arthroplasty (58 percent) or reverse total shoulder arthroplasty (43 percent). Compared to ASA patients, they found that patients who underwent RSA were at higher risk for in-hospital death, multiple perioperative complications, prolonged hospital stay, increased hospital cost, and nonroutine discharge. The authors suggest that physicians may need to be more judicious in offering the procedure and should make sure it is performed only by appropriately trained shoulder specialists.
