Summary
Isolated rotator interval defect closure effectively treated recurrent shoulder instability in young patients. This surgical approach provided adequate stability, avoiding more extensive procedures in selected cases.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Arthroscopy
Background:
- Recurrent shoulder instability often involves defects in the rotator interval.
- Standard surgical stabilization may not always be necessary for isolated rotator interval defects.
Purpose of the Study:
- To evaluate the efficacy of isolated rotator interval defect closure for treating recurrent shoulder instability.
- To determine if this procedure can obviate the need for formal capsular advancement.
Main Methods:
- Fifteen patients with isolated rotator interval defects underwent defect closure (approximation or imbrication).
- Patients were assessed intraoperatively for stability and postoperatively using standardized outcome scales.
- Follow-up averaged 3.3 years.
Main Results:
- All 15 patients achieved good or excellent results on the American Shoulder and Elbow Surgeons and Rowe rating scales.
- Intraoperative assessment confirmed adequate stability after isolated closure.
- No additional stabilization procedures were required.
Conclusions:
- Isolated closure of rotator interval defects is a viable and effective treatment for selected patients with recurrent shoulder instability.
- This technique can provide adequate shoulder stability and may prevent the need for more complex surgical interventions.
