Pearls and Pitfalls in Arthroscopic Decompression of Spinoglenoid Notch Cyst and SLAP Repair

Pearls	Pitfalls
Lateral decubitus position with arm traction is better than beach chair position. This allows for wider working space in the glenohumeral joint. Be prepared for biceps tenodesis in case of concomitant long head biceps tear especially in elderly patients. Use arthroscopic tissue elevator to penetrate the cyst wall. To observe the gelatinous yellow fluid leaking from the cyst, the pressure of arthroscopic pump must be kept low during the cyst wall penetration process.	Posterior portal should not be placed too close to the labrum otherwise iatrogenic labral injury can occur during the plastic cannula insertion. Carefully protect suprascapular nerve by not inserting sharp instrument to exceed 1.5 cm. medial to glenoid rim. Do not open the window at superior capsule to access to the cyst directly. The last source of blood supply that will help promote healing of SLAP repair comes from this tissue.
