Abstract
Objective:
Evaluation of the early results of the implementation of reverse shoulder arthroplasty prosthesis “Comprehensive Reverse” in primary and revision shoulder arthroplasties.
Material and Methods:
September 2010–December 2012, 48 patients (32 women, 16 men) underwent reverse shoulder arthroplasty using Comprehensive Reverse system. Average age of 69.88. A total of 46 patients were followed. In 22 patients the operation was performed for revision. Patients were pre-and postoperatively evaluated using Oxford, Constant, SF-12 scores, radiographs, pain and range of motion. Mean follow-up 13 months.
Results:
In both groups there was an improvement in pain level from 7.9 to 3.2 in the primary replacement group and 7.8 to 5.3 in the revision group. Forward flexion has improved from 60 ° to 107 ° and from 53 ° to 95 ° respectively. Abduction has improved from 52 ° to 90 ° and 42 ° to 77 °, respectively. Significant improvement of Oxford Score from 13.77 to 33.30 in the first group and 12.27 to 21.20 in the second group. Constant score improved from 19.17 to 45.43 and 17.36 to 34.50 in both groups respectively. Furthermore, significant correlations were observed between the key variables.
Post operative Complications includes separation of baseplate–glenosphere (one patient) required revision, large post operative hematoma in one patient and periprosthetic fracture type C in one case after a fall required revision using Mosaic Modular System. There was one case of superficial infection treated surgically and with antimicrobial treatment.
Discussion:
The results of this study show a satisfactory short and acceptable result for the use of reverse shoulder prosthesis “Comprehensive” against primary disease of the shoulder and for revision with better results in the first group. Long-term monitoring is required to better and more complete clinical assessment of the reverse arthroplasty.
