Summary
Arthroscopic decompression and labral repair effectively treats spinoglenoid cysts, significantly improving shoulder function and reducing pain. This surgical approach offers excellent outcomes for athletes and individuals with overhead activities.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Arthroscopy
Background:
- Spinoglenoid cysts are ganglion cysts compressing the suprascapular nerve.
- Conservative treatment failure necessitates surgical decompression.
- Arthroscopic surgery allows intra-articular decompression and labral repair.
Purpose of the Study:
- To evaluate the functional outcomes of arthroscopic spinoglenoid cyst decompression with labral repair.
Main Methods:
- A case series of eight patients with symptomatic spinoglenoid cysts and labral tears.
- Procedures performed between January 2018 and December 2023.
- Assessment using American Shoulder and Elbow Surgeon's (ASES) score, Constant Murley (CM) score, and Visual Analog Score (VAS) pre- and post-operatively.
Main Results:
- Significant improvement in ASES score (61.5 to 90.3) and CM score (66.8% to 93.4%) at 1-year follow-up.
- Marked decrease in VAS pain score (6.3 to 1.0) at 1-year follow-up.
- All patients achieved good to excellent results.
Conclusions:
- Arthroscopic decompression and labral repair is a simple, effective treatment for spinoglenoid cysts.
- This procedure yields excellent functional outcomes for patients, particularly those involved in overhead activities.
