Evaluation of the early results of the implementation of reverse shoulder arthroplasty prosthesis “Comprehensive Reverse” in primary and revision shoulder arthroplasties. 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.Objective:
Material and Methods:
The Copeland shoulder resurfacing arthroplasty (CSRA) (Figure1) is a cementless, pegged humeral head surface replacement which has been in clinical use since 1986. The indications for CSRA are more or less the same as conventional stemmed arthroplasty. This procedure can be considered for all patients who require shoulder replacement due to GHJ arthritis resulted from primary or secondary OA, RA, and other variations of inflammatory arthritis. It is also suggested as the first choice option for relatively young patients with post-traumatic arthritis, avascular necrosis (AVN), and instability arthropathy. This observational study reports functional and radiological outcome in CSRA during 4 years follow-up. 109 consecutive patients with primary osteoarthritis (45.9%), rheumatoid arthritis (39.4%), rotator cuff arthropathy (9.2%), and avascular necrosis (5.5%) underwent CSRA. Patients including 68 females (63%) and 41 males (37%) underwent this procedure (63 right-sided and 46 left-sided including 9 bilateral shoulders). The outcome assessment included pain and satisfaction, Oxford Shoulder Score (OSS), Constant Score (CS), and SF-12. Imaging was reviewed for glenoid morphology (Walch classification) (Figure2) and humeral head migration. The average follow-up period was 4 years, (range: 1 to 10 years).Background
Methods
Reverse total shoulder arthroplasty (RTSA) provides an alternative to standard total shoulder arthroplasty in the treatment of selected complex shoulder problems including failed shoulder replacements. The purpose of this report is to present outcome of RTSA using Comprehensive Reverse System (CRS) as either primary or revision treatment choice. Between September 2010 and April 2012, 54 patients (36 females, 18 males) with the mean age of 68.4 (±10) underwent RTSA-CRS. In 27 patients RTSA-CRS was performed as a revision due to failed previous arthroplasty. Primary underlying conditions included AVN (2), massive irreparable rotator cuff tear (2), primary osteoarthritis (7), post-traumatic osteoarthritis (2), rheumatoid arthritis (6), and rotator cuff arthropathy (8). It was not possible to complete the operation in 6 patients (4 revisions group 2 AVN cases) due to substantial glenoid erosion. Preoperative CT scan was performed in 50% of patients to assess the bony stock of the glenoid. In some patients ultrasound and MRI were performed to acquire additional information. A total of 46 patients were followed-up by means of antroposterior and axial plain X-rays, pain and satisfaction level (VAS/0–10), stiffness, Constant Score, Oxford Shoulder Score, SF-12 (Physical and mental Subscales), and range of movement for a mean duration of 6.5 months (±4.2).BACKGROUND
