Do shoulders with massive cuff tears have supra scapular neuropathy

Neuropathy of the suprascapular nerve and massive rotator cuff tears: a prospective electromyographic study

Prior authors have suggested the need for releasing the suprascapular nerve when massive cuff tears are repaired. These authors prospectively evaluated the suprascapular nerve for preoperative neurodiagnostic abnormalities in shoulders with massive cuff tears. 49 patients with retracted tears of both supraspinatus and infraspinatus were evaluated.

6 (12%) had neurologic lesions noted on electromyography: 1 radicular lesion of the C5 root, 1 affected electromyogram in the context of a previous stroke, 3 cases of partial axillary nerve palsy with a history of shoulder dislocation; only 1 had suprascapular nerve neuropathy.

This study does not support the need for routine suprascapular nerve release in cuff repair.
