Introduction We describe a safe surgical technique for arthroscopic decompression of a suprascapular notch cyst in the setting of compressive suprascapular neuropathy.
Step 1: Position the Patient Position the patient in the standard beach-chair position.
Step 2: Mark Anatomic Landmarks Palpate and mark the subcutaneous landmarks of the shoulder in preparation for later arthroscopy.
Step 3: Diagnostic Arthroscopy Create standard anterior and posterior portals for glenohumeral visualization.
Step 4: Perform Suprascapular Cyst Decompression Through a Lateral Subacromial Approach Establish accessory superior and lateral portals and transition to a lateral viewing portal to perform suprascapular notch decompression.
Step 5: Release the Transverse Scapular Ligament Establish a G Portal and release the transverse scapular ligament using arthroscopic scissors.
Step 6: Closure Perform arthroscopic lavage of the subacromial space and glenohumeral joint and close arthroscopic portals.
Results As suprascapular nerve entrapment is a relatively rare entity, with only a limited number of studies from which to draw conclusions regarding the outcomes of arthroscopic suprascapular nerve release, Shah et al. recently reported on their results in twenty-four patients using this surgical technique.
Pitfalls & Challenges
We describe a safe surgical technique for arthroscopic decompression of a suprascapular notch cyst in the setting of compressive suprascapular neuropathy.
The suprascapular nerve is a branch of the upper trunk of the brachial plexus and contains contributions from C4, C5, and C6. The nerve passes posterolaterally from the brachial plexus through the posterior triangle of the neck and inferior to the transverse scapular ligament to the suprascapular notch, which lies just medial to the base of the coracoid1. The suprascapular nerve gives off sensory fibers to the glenohumeral joint and motor function to the supraspinatus and infraspinatus muscles1,2, and can be compressed along this course. The most well-recognized sites of …
