A Case of Recurrent Posterior Dislocation of the Shoulder Joint

Abstract

Recurrent posterior dislocation of the shoulder joint is rare lesion and its operated cased of Japan are 12 cases in the literature.Our patient is a 20 years old male. He complained that his right shoulder dislocates each time he abducts and slightly internally rotates his arm. But he could easily reduce the dislocation himself by rubbing his shoulder. The initial dislocation occured in 1964, and in the following 2 years he had not experienced dislocation. But 2 years after initial dislocation, he became aware of recurrent dislocation by weight carrying or rotation of his arm.On September 11, 1968, plication of the posterior capsule was carried out under local anaesthesia. When the capsule opened by a vertical incision, no defect in the humeral head and glenoidal labrium was found. Repair was performed by suturing the lateral flap of the incised capsule to the posterior glenoidal rim and overlapping the lateral edge of the capsule flap over the posterior glenoidal rim. After operation the shoulder was abducted and fixed in a plaster bandage. The plaster bandage was removed after 5 weeks.8 months after operation, he has no complaint. The right shoulder is symptomless and its function is normal.
