Arthroscopic Intra-articular Spinoglenoid Cyst Resection Following SLAP Repair

Abstract

Spinoglenoid cyst (SGC) is a ganglion arising in the spinoglenoid notch and is thought to be related to SLAP lesion. This cyst often compresses the suprascapular nerve in the spinoglenoid notch. Symptomatic cysts require surgical treatment when conservative treatment fails. In particular, arthroscopic decompression through the torn labral tissue when the cyst is extending into the joint cavity is easy and convenient. However, if the cyst is confined to the spinoglenoid notch, arthroscopic approach through the torn labral tissue is challenging. Thus, we present our preferred technique of addressing the SGC through an additional superior capsular window after completing SLAP repair. We believe that our technique is easy, reproducible, and reasonable.

Transcapsular Decompression of Shoulder Ganglion Cysts

“…Some authors have reported a transcapsular technique of resecting the cyst in its entirety, with debridement of all margins of the cyst. This technique may be time-consuming and may still pose a risk to the SSN 16 . Our limited capsulectomy allows excellent visualization of the extent of the cyst, minimizes the chance of recurrence, is technically fast and simple to perform, and has shown good results with excellent reproducibility.…”

Arthroscopic Decompression of Spinoglenoid Notch Cyst and SLAP Repair Through a Single Working Portal

“… 4 , 6 There are some various types of surgical techniques, namely, labral repair alone without cyst decompression, cyst decompression through labral tear with labral repair, and cyst excision through superior capsule window with labral repair. 7 , 8 , 9 …”
