Background: Reverse total shoulder arthroplasty provides a surgical
alternative to standard total shoulder arthroplasty for the treatment of
selected complex shoulder problems. The purpose of the present study was to
evaluate the effects of etiology on the results of reverse total shoulder
arthroplasty.
Methods: Between May 1995 and June 2003, 240 consecutive reverse
total shoulder arthroplasties were performed in 232 patients with an average
age of 72.7 years. Patients were grouped according to etiology, and the
clinical and radiographic outcomes for each group were measured and
compared.
Results: One hundred and eighty-six patients with 191 retained
reverse total shoulder arthroplasty prostheses were followed for an average of
39.9 months. Overall, the average Constant score improved from 23 points
before surgery to 60 points at the time of follow-up and 173 of the 186
patients were satisfied or very satisfied with the result. Although
substantial clinical and functional improvement was observed in all etiology
groups, patients with primary rotator cuff tear arthropathy, primary
osteoarthritis with a rotator cuff tear, and a massive rotator cuff tear had
better outcomes, on average, than patients who had posttraumatic arthritis and
those managed with revision arthroplasty. Dislocation (fifteen cases) and
infection (eight cases) were the most common complications among the 199
shoulders that were followed for two years or were revised prior to the
minimum two-year follow-up. Patients who received the reverse prosthesis at
the time of a revision arthroplasty had a higher complication rate than did
those who received the reverse prosthesis at the time of a primary
arthroplasty.
Conclusions: The reverse total shoulder arthroplasty prosthesis can
produce good results when used for the treatment of a number of other complex
shoulder problems in addition to cuff tear arthropathy. Patients with
posttraumatic arthritis and those undergoing revision arthroplasty may have
less improvement and higher complication rates in comparison with patients
with other etiologies. The advanced age of the patients in the present series
and the relatively short duration of follow-up suggest that the prosthesis
should continue to be used judiciously.
Level of Evidence: Prognostic Level II. See Instructions
