Abstract:

BACKGROUND: With the development of surgical techniques and reconstruction material technology, joint replacement has also been widely used in the dislocation of the shoulder; especially all kinds of custom-made or assembled prosthesis make replacement indications improved evidently.
OBJECTIVE: To investigate the long-term effects of arthroscopy or arthroplasty for treating recurrent anterior dislocation of the shoulder joint with severe bone defects.
METHODS: 144 patients with recurrent anterior dislocation of the shoulder joint with severe bone defects were enrolled in this study. They were divided into treatment group and control group based on a random drawing (n=72). The control group was given arthroscopic surgery, and the treatment group was subjected to arthroplasty. The 3 years of followed-up were done by telephone investigation and further consultation. Neer shoulder score, shoulder activity and complications were recorded. 
RESULTS AND CONCLUSION: After 3-year followed-up, the excellent and good rate of shoulder function was significantly higher in the treatment group (90%) than in the control group (81%) (P < 0.05). The magnitude of the flexion in the 3-year followed-up was apparently increased, while the lateral margin external rotation was decreased, which showed significant differences after intragroup comparison (P < 0.05). Simultaneously, the magnitude of the flexion and the lateral margin external rotation in the treatment group had statistically significant differences compared to the control group in the 3-year followed-up (P < 0.05). The complications of wound infection, shoulder dislocation, and implant loosening in the treatment group during follow-up were significantly lower than in the control group (P < 0.05). These findings verified that compared with arthroscopic surgery, arthroplasty for treating recurrent anterior dislocation of the shoulder joint with severe bone defects in long-term follow-up can effectively restore shoulder function and range of motion, and it has few complications, thereby effectively rebuilds shoulder joint.
