Entrapment neuropathy of the suprascapular nerve

Five patients were found to have suprascapular entrapment, diagnosed by clinical and electromyographic findings. A positive EMG including a delayed nerve condition is necessary confirming evidence of the need for surgical treatment. Hypertrophy of the transverse scapular ligament was found to be the cause in three cases and its release gave one excellent and two good results. A ganglion in the spinoglenoid fossa was the cause of entrapment of the lower branch of the suprascapular nerve in two cases and its excision along its pedicle gave excellent results
