She recalled no trauma, and the symptoms were exacerbated by exercise and abated with rest.

[Suprascapular nerve entrapment].

Seven patients were operated: The ligament was removed and the nerve was neurolysed. The average age was 36 years. All patients showed pathological findings in electrophysiological suprascapular nerve entrapment clinical examination.

Five patients had an atrophy of both scapula muscles, two showed only infraspinatus muscle atrophy one with a ganglion in the distal course of the nerve.

Blunt dissection using the trocar is used to sweep away soft tissue and posteriorly retract the supraspinatus. The transverse scapular ligament can be identified by its glistening, white fibers and by the position of its lateral fibers, which insert at the medial base of the conoid ligament.

The suprascapular artery generally courses superior suprascapular nerve entrapment the transverse scapular ligament. If needed, needle localization can be used to create another superior portal at the standard Neviaser portal position junction of scapular spine and posterior aspect of acromioclavicular joint.

An elevator can be inserted through this portal to better define the transverse scapular ligament. With the suprascapular nerve protected with a probe or blunt trocar, the transverse scapular ligament suprascapular nerve entrapment cut as far laterally as possible using arthroscopic scissors.


The suprascapular nerve is probed to ensure adequate decompression. An arthroscopic burr may be used to remove any bony structures suprascapular nerve entrapment residual compression. The spinoglenoid notch may be decompressed either through the glenohumeral joint or the subacromial space.

Patients with superior labrum anterior-posterior SLAP lesions requiring repair should undergo repair prior suprascapular nerve entrapment suprascapular nerve decompression. After repair is complete, the arthroscope is placed in the anterior portal to visualize the posterior superior capsule.

The posterior superior capsule is incised from the 9-o'clock to the o'clock positions by placing a shaver through the posterior portal. The posterior band of the inferior suprascapular nerve entrapment ligament should be identified prior to capsular release so that it is not inadvertently damaged.

Next, suprascapular nerve entrapment the fibrous raphe between the supraspinatus and infraspinatus provides a useful landmark. It is seen lateral to the spinoglenoid notch and can be followed medially until the cyst can be visualized on the scapula.

The cyst is then decompressed using a shaver. Synovial fluid should be seen, and all visible portions of the cystic wall are removed to reduce recurrence risk. suprascapular nerve entrapment

If no suprascapular nerve entrapment tear is noted on diagnostic arthroscopy, a spinoglenoid notch cyst can be decompressed from the subacromial space. A lateral portal is established and serves as the viewing portal.

A shaver is introduced from the posterior portal and a subacromial debridement is performed. Dissection is performed from the scapular spine medial border to the posterior glenoid anterior border.
