Summary
Inferior capsular shift surgery effectively treats multidirectional glenohumeral instability in athletes. Most athletes return to their previous sport and activity levels with good outcomes and an acceptable failure rate.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Instability
Background:
- Multidirectional glenohumeral instability often results from capsular and ligamentous redundancy.
- Surgical intervention is considered for athletes unable to return to sport due to instability.
Purpose of the Study:
- To evaluate the outcomes of inferior capsular shift surgery in athletes with multidirectional glenohumeral instability.
- To assess return to sport rates, patient-reported outcomes, and failure rates after this procedure.
Main Methods:
- Retrospective evaluation of 25 athletes (26 shoulders) undergoing inferior capsular shift.
- Assessment at a median of 54 months post-operation using Rowe and University of California at Los Angeles (UCLA) scores.
- Data collection included return to preinjury activity level and sport-specific participation.
Main Results:
- 84% of athletes returned to their preinjury activity level; 76% returned to overhead sports.
- 57% remained active at their preinjury level at follow-up.
- 88% excellent/good Rowe scores and 92% excellent/good UCLA scores; 8% failure rate.
Conclusions:
- Inferior capsular shift is a successful treatment for multidirectional instability due to capsular redundancy.
- The procedure restores range of motion and allows a high rate of return to demanding sports.
- Acceptable failure rates support this surgical technique for athletes.
