Periarthropathia humeroscapularis and cervical disc herniation.

Periarthropathia humeroscapularis (PHS) is a malfunction of the shoulder girdle due primarily to diseases of the periarticular tissue and the joint capsule. Clinically a primary and a secondary syndrome are defined. Spondylogenous cervical spine conditions play an important role as causative factors in secondary PHS, among them cervical disc herniation. Among 141 patients operated on for cervical disc herniation 14 presented with a PHS-syndrome prior to surgery, and 31 patients developed the syndrome postoperatively. The patients belong to a fairly young population and showed no high incidence of a particularly severe cervical spondylosis.
