The aim of this study was to analyse the complication rates of six different shoulder arthroplasty concepts for different diagnoses in the short and midterm. The study included 485 primary shoulder arthroplasties. The mean follow-up of the cohort was 3.5 (1-10) years. Complications were classified into three categories: (1) without reoperation, (2) soft tissue revision and (3) implant revision. In total, 56 complications were recorded (11.6%): 34 (7%) were category 1 complications, 11 (2.3%) were category 2 and 11 (2.3%) were category 3. For the whole cohort the median follow-up was 1.6 years (1-10 years) and the survival rate without any complication was 90.5% (95% CI: 87.9-93.1). Patients rated the result of their surgery in 270 (55.7%) cases as very satisfied, in 148 (30.5%) as satisfied, in 43 (8.9%) as somewhat disappointed and in 24 (4.9%) as disappointed. A relatively low complication rate was found in this study. Longterm observations are necessary to confirm these results.

“…However, satisfactory results have been described by Sarris et al in patients with CTA [21]. The complication rates described in the recent literature vary between 0 and 23% [25,28,29]. If the glenoid component of a reversed arthroplasty, which would be the implant of choice, does not achieve primary stability because of insufficient glenoid bone stock, we would recommend the bipolar prosthesis as a second line of defence implant.…”

“…CTA is the most common indication for a bipolar shoulder implant [21,25,28,29]. Because of the limited range of motion between the shell and the inner head of the implant, only limited functional improvement can be expected.…”

The aim of this prospective study was to propose a classification for shoulders with massive rotator cuff defects based on patients' clinical symptoms. A total of 100 shoulders with massive rotator cuff tears were evaluated clinically using the Constant score (CS) and with radiographs in two planes. Three types were defined and correlated with radiographic findings: (1) the arthritic type (type I), (2) the non-reactive type (type II) and (3) the necrotic type (type III). Significant differences in the overall CS (type I: 28.6 points, range: 4 -61; type II: 18.8 points, range: 6 -52; type III: 15.5 points, range: 6 -31) and its subgroups and in shoulder motion were found between types I and II and between types I and III (p< 0.05). This classification may be helpful for the decisionmaking process with regard to the appropriate form of shoulder replacement surgery in patients with massive rotator cuff defects.

The use of reverse total shoulder arthroplasty (RTSA), a protocol based on the principles of Delta III reverse prosthesis, has been increasing for its efficacy in the treatment of massive cuff tear and cuff tear arthropathy.…”

Background: To evaluate the effect of preoperative fatty degeneration of deltoid and teres minor muscles on the clinical outcome in patient with reverse total shoulder arthroplasty (RTSA). Methods: Nineteen patients with RTSA were enrolled. The mean follow-up period was 16.1 months. The fatty degeneration of three distinct parts in each deltoid and the teres minor muscle was measured using a preoperative magnetic resonance imaging. Postoperatively, the muscle strengths for forward elevation (FE), abduction (Abd), and external rotation (ER) were measured using a myometer at the last follow-up. The parameters for clinical outcome were Constant Score (CS) and Korean Shoulder Score (KSS). Results: The number of cases was 10 in group 1 and 9 in group 2. The strength of FE and Abd were significantly higher in group 1 (p<0.001 and p<0.001, respectively), and the strength of ER was not different significantly between two groups (p=0.065). For the clinical outcome, both CS and KSS were higher in group 1 (p=0.002 and p=0.002, respectively). The number of patients in group A was 11, and group B was 8. Although there was not a significant difference in terms of FE and Abd between group A and B (p=0.091, p=0.238), ER was significantly higher in group A (p=0.012). We did not find a significant difference in the clinical scores (CS, p=0.177 and KSS, p=0.238). Conclusions: These findings suggest the importance of a preoperative evaluation of the fatty degeneration of deltoid and teres minor muscles for predicting postoperative strength and clinical outcome.
