Abstract

PURPOSE
The purpose of this study was to analyze complications after reverse total shoulder arthroplasty and report the clinical outcomes with review of previously reported studies.
MATERIALS AND METHODS
Complications after reverse total shoulder arthroplasty were analyzed for 98 patients who underwent reverse total shoulder arthroplasty and were followed-up for at least 6 months. Of 98 patients, 22 were men and 76 were women. The mean age was 75.0+/-6.5 years (range, 59-92 years) with a mean follow-up period of 22+/-19 months (range, 6-74 months). The types and time of occurrence of complications, methods of treatment, and clinical outcomes at the final follow-up were analyzed.
RESULTS
Complications occurred in 18 of 98 patients (18.4%). Seven of them received operative treatment and 11 were treated conservatively. Two cases had postoperative dislocations and were addressed with open reduction. In 2 cases, periprosthetic fractures occurred and were treated with open reduction and plate fixation. Two acromial stress fractures and 8 cases of heterotopic ossification were managed conservatively. Infection and humeral component loosening occurred in one case, respectively, and were treated with revision arthroplasty. Glenoid component loosening occurred in 2 cases, one of which was treated with revision arthroplasty and the other was managed conservatively. At the final follow-up, clinical outcomes showed a statistically significant improvement. Compared to groups with no complications, there were no significant differences in final clinical outcomes. Scapular notching occurred in 43.9% (43/98 cases). No statistically significant differences of clinical outcomes were observed between the scapular notching group and the no notching group (p>0.05).
CONCLUSION
In our study, 18% of complications occurred after reverse total shoulder arthroplasty and final clinical outcomes of these complications showed significant improvement. Scapular notching developed in 44% and did not provide a significant clinical effect at short term follow-up.
