Entrapment neuropathy of the suprascapular nerve with pain and weakness of the affected shoulder is a rare clinical entity for which several treatment modalities have been reported. Instead of trying to evacuate the cyst from within the joint, the cyst was approached through the subacromial space after subacromial bursectomy, exposure of the spinoglenoid notch, and insertion of a small retractor through an additional posterior portal. This allowed retraction of the infraspinatus muscle together with the inferior branch of the suprascapular nerve for better visualization. After localization of the cyst and nerve, the membrane was incised and the entire viscous contents could be aspirated with a shaver. The intra-articular area of labral detachment was then repaired like a posterior aspect of a SLAP II lesion. The technique described combines the advantages of open and arthroscopic surgery, allowing one to address the underlying intra-articular pathology, completely evacuate the ganglion cyst, and protect the suprascapular nerve.

We report a case of suprascapular nerve entrapment at the suprascapular notch combined with a type II SLAP lesion resulting in supraspinatus and infraspinatus muscle weakness and shoulder pain in a 27-year-old female professional handball player. The magnetic resonance imaging scan showed significant atrophy of the supraspinatus and infraspinatus muscles. Electromyography revealed an isolated proximal lesion of the suprascapular nerve. The patient was treated by an arthroscopic release of the superior transverse ligament and repair of the type II SLAP lesion. Follow-up evaluations were performed 6 weeks, 3 months, and 6 months postoperatively. The Constant score improved from 51 to 84 points. Electromyography studies 3 and 6 months after surgery showed significant improvement with normal reinnervation of the supraspinatus and infraspinatus muscles. To our knowledge, this is the first report of proximal suprascapular nerve entrapment with coincidence of a SLAP lesion that was treated arthroscopically. On the basis of this case, we found that arthroscopic release of the superior transverse ligament is an effective procedure for decompression of the suprascapular nerve. Although it is a technically demanding procedure, the arthroscopic approach has the advantage of detecting concomitant lesions such as SLAP lesions.

A SLAP lesion can be found with a concomitant spinoglenoid notch cyst. The cyst can cause suprascapular nerve compression, resulting in shoulder pain and weakness of external rotation. Their management varies from conservative treatment to operative treatment. Cyst decompression through the labral tear is our preferred treatment. Previous studies demonstrated a good result after arthroscopic decompression of the cyst through the labral tear combined with SLAP repair. Many surgeons usually use 3 portals to perform this procedure. However, we prefer to use only 2 portals, 1 anterior viewing portal and 1 posterior working portal. This strategy is more time and cost efficient. The patient is positioned in lateral decubitus. The SLAP lesion is demonstrated by using a probe. Tissue elevator is inserted into the labral lesion to penetrate into the cyst wall. A soft anchor is placed. A birdbeak suture passer penetrates the posterior labrum. Then knot tying is done. The advantages of this single working portal technique are short operative time, a decreased risk of iatrogenic rotator cuff injury from accessory anterolateral portal or posterior labral injury from posterolateral portal, and avoiding unnecessary superior capsule incision for cyst exposure.

Paralabral cysts are an increasingly recognized cause of suprascapular nerve (SSN) impingement, often causing insidious weakness in the rotator cuff. Compression at the suprascapular notch is often due to the presence of a SLAP tear and leads to pain, weakness, and atrophy of both the supraspinatus and infraspinatus muscles. Compression of the SSN at the spinoglenoid notch leads to weakness and atrophy of the infraspinatus only. Arthroscopic decompression of cysts with repair of labral pathology is typically performed in a sublabral fashion, which may make visualization of the extent of the cyst difficult and places the SSN at increased risk. With any approach, an intimate knowledge of the anatomy of the SSN is vital to safe decompression. We present a surgical technique for decompression of paralabral cysts using an intra-articular transcapsular approach. This approach maximizes visualization and efficiency and reduces possible damage to the SSN.
