Suprascapular neuropathy in the differential diagnosis of rotator cuff injuries

Abstract

Four cases of suprascapular neuropathy treated by nonoperative means have been presented. Complete recovery occurred in all four. The anatomy of the suprascapular nerve and probable mechanisms of injury secondary to traction have been discussed. The importance of electromyography in diagnosis has been stressed. Longer periods of nonoperative treatment are recommended here than by previous authors. Since the lesion is felt not to be an entrapment phenomenon but, rather, a traction injury, operative treatment should consist of release of the nerve at the notch to reduce the possibility of further traction injury, and a neurolysis should be done as well.
