Abstract
We report a case of habitual posterior dislocation of the shoulder. The patient is a 16-year-old boy in high school. He started karate exercises when he was 3-years old.
He had been feeling pain and apprehension on movement since 1992.
On examination, the left shoulder demonstrated posterior dislocation in the position of flexion 90° and internal rotation 45°.
Radiographs and CT showed dysplasia of the glenoid fossa and relaxation of the posteroinferior capsular.
At surgery, there were no signs of any distinct injured lesions.
Glenoid osteotomy and inferior capsular shift were performed in this patient.
One year after surgery, he restarted Karate exercises. 6 months after resuming this activity he remains free of problems.
