Suprascapular nerve entrapment. A report of two cases treated with suprascapular notch resection.

Suprascapular nerve entrapment occurs in the shoulder after a severe forward flexing injury (hyperprotraction) because of tethering of the nerve in the scapular notch. Unrelenting pain in this shoulder region is relieved by section of the transverse scapular ligament in most cases. Two patients, reported here, had temporary relief from simple transverse scapular ligament release and later lasting relief of pain from scapular notch resection. These observations suggest that primary wide notch resection may be the preferable procedure.
