ABSTRACT
Complex proximal humerus fractures in older patients can be treated with hemiarthroplasty (HA) or reverse shoulder arthroplasty (RSA), with both providing good pain relief and function. This study compared the costs, complications, and outcomes of HA vs RSA after proximal humerus fracture in older patients. Patients 65 years or older who were admitted between January 2007 and August 2011 with a 3- or 4-part proximal humerus fracture and treated with HA or RSA were identified. Surgeries were performed at the same institution by 1 of 3 surgeons trained in trauma or shoulder surgery. Operating room costs, implant costs, total costs to the patient and hospital, and range of motion were compared. In the study group, 8 patients (7 women and 1 man; mean age, 77 years) received HA and 16 patients (13 women and 3 men; mean age, 77 years) received RSA. Hemiarthroplasty implant cost and operating room cost were $9140 and $8900 less than those of RSA, respectively (P<.001). The total cost to the patient was $33,480 for HA vs $57,000 for RSA (P<.001) with no difference in admission length, transfusion requirements, or final range of motion. In patients with complex proximal humerus fractures, RSA restored function similar to HA and resulted in better pain and outcome scores. However, RSA had a significantly higher cost to both the patient and the hospital compared with HA. Further investigation of postsurgical rehabilitation costs, skilled nursing needs, or revision surgery will elucidate whether there is long-term functional or financial benefits to RSA over HA.
