(case 1) A 75-year-old female with a recurrent shoulder dislocation. As the chronicity of the dislocating increased, so did the difficulties of reduction. There was a compression defect in the articular surface of the humeral head. The humeral head was locked on the rim of the glenoid. Since the humeral head redislocates easily, resection of the humeral head was performed. Three years after surgery she had regained motion as follows: elevation 90°, external rotation 50°, internal rotation to L1. She had pain and a click when she elevated her shoulder. The radiographs showed the humeral head elevated toward the glenoid and made a hinge joint.
(case 2) A 76-year-old female with a recurrent shoulder dislocation. Dislocation was impossible to reduct because of a depression fracture of the humeral head. Resection of the humeral head was performed. Five years after surgery she had regained motion as follows: elevation 120°, external rotation 10°, internal rotation to L5. She had no pain. The radiographs showed the interval between the humeral head and the glenoid had become narrow.
(case 3) A 47-year-old female with tuberculous arthritis. The humeral head was destructive, so a curettage and resection were performed. Six years after surgery she have regained motion as follows, elevation 110°, external rotation 10°, internal rotation to L5. She had pain and a click in elevation. In the radiographs the humeral head had elevated toward the glenoid and made a hinge joint. Pain relief in elevation was good, but there remained motion pain in the internal rotation. In the radiographs, a year after surgery the edge of the humerus was V-shaped. Two years after surgery, the humerus had made a hinge joint with glenoid. The Shoulder Joint, Vol.21, NA,547-551,1997. (Discussion & Conclusion) In resection of the humeral head, as time passes the elevates upward and makes a hinge joint with the glenoid. After surgery, elevation is good, but rotation is limited. Patients complain of motion pain in internal rotation. Indications should be considered carefully.
