Introduction:
A spinoglenoid cyst is a ganglion cyst that compresses the suprascapular nerve in the spinoglenoid notch. On failure of the conservative treatment, surgical decompression is the treatment of choice. The arthroscopic method helps to decompress the cyst intra-articularly through the labral tear and also allows repair of the labral tear. This study aims to bring out the functional outcome of arthroscopic Spinoglenoid Cyst Decompression with labral repair.
Materials And Methods:
This study is a case series of eight symptomatic Spinoglenoid cysts with labral tears which were treated with arthroscopic cyst decompression and labral repair over 5 years from January 2018 to December 2023. The American Shoulder and Elbow Surgeon's score (ASES), Constant Murley (CM) score, and Visual Analog Score (VAS) were used to assess the patients preoperatively and postoperatively at regular intervals.
Results:
All the patients had good to excellent results. There was a significant improvement in the ASES from a mean pre-operative 61.5 to a mean 1-year follow-up of 90.3, while the CM score improved from a mean pre-operative 66.8% to a mean 1-year follow-up of 93.4%. The VAS decreased from a mean pre-operative 6.3 to a mean 1-year follow-up of one.
Conclusion:
Spinoglenoid Cyst is usually seen in individuals and athletes who are involved in an overhead activity. Arthroscopic decompression of the cyst and labral repair is a simple and effective treatment and gives excellent functional outcomes.
