Summary
Arthroscopic resection of the medial superior scapula hook formation effectively treats painful snapping scapula when conservative methods fail. This surgical intervention significantly improves patient-reported pain and function, offering a valuable treatment option.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Shoulder Arthroscopy
Background:
- Painful snapping scapula is a debilitating condition.
- Conservative treatments like rehabilitation may not always provide relief.
Purpose of the Study:
- To evaluate the efficacy of arthroscopic bone resection of the medial superior scapula corner.
- To assess outcomes in patients with persistent painful snapping scapula.
Main Methods:
- Prospective study of 20 patients undergoing arthroscopic scapulothoracic bursectomy and hook formation resection.
- Preoperative assessment included response to local anesthetic and 3-month rehabilitation.
- Western Ontario Rotator Cuff (WORC) index used for pain and function evaluation.
Main Results:
- Significant improvement in median WORC score from 35.0 to 86.4 post-surgery.
- 18 out of 20 patients experienced improvement.
- 19 patients would recommend the surgery.
Conclusions:
- Arthroscopic resection of the medial superior scapula hook formation with bursectomy is effective for painful snapping scapula unresponsive to rehabilitation.
- The procedure offers significant gains in patient-reported outcomes (WORC score).
- Considered an effective treatment option for most patients, despite one serious complication.
