Recurrent anterior dislocation of shoulder joint.

111 patients with fresh dislocation of shoulder joint were treated with modified Putti-Platt procedure. Of these, 17 had recurrent anterior dislocation. 13 patients were followed up on the average for 25 years. According to Rowe criteria, 10 patients (76.9%) showed excellent results, 2 (15.4%) good, and (7.7%) fair. No recurrence and restriction of external rotation were found. Clinical experience and fetal investigation on congenital factors of recurrent shoulder dislocation were described.

Anterior capsular redundancy of the shoulder: congenital or traumatic? An embryological study.

A study of the attachment of the joint capsule to the scapula, and of the shape of the humeral head, has been carried out in 52 fetal and embryonic shoulders. In 77% of cases the anterior capsule was attached to the labrum or close to it; in the remaining 23% it was inserted into the neck of the scapula, so creating a pouch. In all 52 specimens the humeral head was spherical. It was concluded that the pouched and redundant anterior capsule sometimes seen during surgery for recurrent dislocation of the shoulder, may not be traumatic in origin, but could be a developmental variant.
