Reverse shoulder arthroplasty shows superior functional results for rotator cuff tear arthropathy

New Zealand researchers concluded reverse shoulder arthroplasty performed better than hemiarthroplasty in an elderly population with rotator cuff-deficient shoulders.
“In this unselected population with rotator cuff tear arthropathy, controlled for age, sex, and [American Society of Anesthesiologists] ASA score, reverse shoulder arthroplasty resulted in a functional outcome that was superior to that of hemiarthroplasty,” Simon W. Young, FRACS, and colleagues wrote in their study abstract. “Longer term follow-up is needed to confirm these findings.”
Young and colleagues examined data from the New Zealand Joint Registry and compared 102 patients undergoing primary hemiarthroplasty for rotator cuff tear arthropathy to 102 patients who also had rotator cuff tear arthropathy undergoing reverse shoulder arthroplasty. They utilized the Oxford Shoulder score (OSS) and ASA score, comparing mortality rates, revision rates and shoulder outcomes in both groups.
At 6-month follow-up, OSS was 31.1 points in the hemiarthroplasty group and 37.5 in the reverse shoulder group, according to the abstract. Young and colleagues noted 9 revisions in the hemiarthroplasty group and 5 revisions in the reverse shoulder group; however, there was no difference between the mortality rates in either group.
