Summary
Surgical repair of traumatic posterior shoulder instability yields favorable outcomes. Arthroscopic techniques with capsular plication demonstrated superior results compared to open procedures, offering a promising treatment for this condition.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Instability Research
Background:
- Traumatic posterior shoulder instability often results from specific forceful movements.
- Surgical interventions are effective, with current arthroscopic methods potentially reducing patient morbidity.
Purpose of the Study:
- To assess the outcomes of surgical shoulder stabilization in patients experiencing traumatic posterior instability.
Main Methods:
- A case series (Level of evidence, 4) evaluated patients undergoing open or arthroscopic posterior stabilization.
- Outcomes were measured using validated subjective assessments and physical examinations.
Main Results:
- 31 shoulders underwent posterior stabilization; 19 arthroscopically and 12 open.
- Arthroscopic repair showed statistically better outcomes (Western Ontario Shoulder Instability Index, Rowe score) than open repair.
- 29 of 31 shoulders achieved excellent or good ratings post-surgery.
Conclusions:
- Posterior shoulder instability involves labral, articular edge, and capsular lesions.
- Both open and arthroscopic surgical treatments provide satisfactory results.
- Arthroscopic repair with suture anchors and capsular plication yielded the most favorable outcomes.
