Suprascapular nerve entrapment

Suprascapular nerve compression is a true peripheral entrapment neuropathy that can be cured by lysis of the suprascapular ligament and freeing the suprascapular nerve. It is a rare entity that must be considered in the differential diagnosis of radicular pain, as well as that of the shoulder. Four examples of suprascapular nerve neuropathy in three patients are described, including one case of bilateral entrapment; all were young females. One was diagnosed as systemic lupus erythematosus (case 3); it is now considered that a second patient (case 2) may have the same disorder. The clinical, anatomic, and surgical considerations of the suprascapular nerve are considered in this paper.
