Silastic interposition arthroplasty of the shoulder
Summary
Silastic interposition shoulder arthroplasty showed a 50% failure rate due to dislocation or fragmentation. This procedure is best suited for rheumatoid arthritis shoulders without bone loss or humeral head distortion.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Silastic interposition arthroplasty is a surgical technique for shoulder joint reconstruction.
- Previous studies have indicated varying success rates for this procedure.
Purpose of the Study:
- To evaluate the outcomes of Silastic interposition arthroplasty in shoulder joints.
- To identify factors contributing to the success or failure of the procedure.
Main Methods:
- A retrospective review of 12 patients who underwent Silastic interposition arthroplasty of the shoulder.
- Analysis of device integrity, including dislocation and fragmentation, and patient outcomes.
Main Results:
- A high incidence of complications, with 50% of cases experiencing device dislocation or fragmentation.
- Seven out of 12 patients (58.3%) experienced early device failure.
- Successful outcomes were associated with specific patient criteria.
Conclusions:
- Silastic interposition arthroplasty has a high rate of early failure due to mechanical complications.
- The procedure should be reserved for rheumatoid arthritis patients with intact bone stock and non-deformed humeral heads.
