We reported on a case of recurrence after Oudard-Iwahara procedure for recurrent anterior dislocation which was performed approximately twenty years ago. A 56 year old man suffered in recurrent dislocation of his right shoulder after a traffic accident and he received shoulder stabilization procedure, when he was 30 years old. After the operation, his shoulder ROM was restricted but his shoulder apprehension disappeared. When he was 50 years old, he hit his right shoulder against a colleague, and his shoulder apprehension relapsed. After that, his shoulder apprehension increased gradually, so he consulted us in March 2004.His shoulder ROM was restricted to120 degree flexion, 110 degree abduction, 30 degree 2nd external rotation, anterior apprehension sign and relocation test were positive. The X rays revealed the grafted bone which is continued to the coracoid process, and CTA and MRA revealed anterior labral injury. We performed arthroscopic Bankart repair in August 2004. 3 years after the operation, his shoulder apprehension disappeared. His shoulder ROM was 150 degree flexion, 180 degree abduction and 65 degree 2nd external rotation.And he returned to work. Reports of a recurrence after Oudard-Iwahara procedure were rare. The factor related to recurrence was bone resorption of the grafted bone, but in this case bone resorption was not clear. We thought the causes of recurrence of this case were Bankart lesion, decrease of volume of the subscapularis muscle and change of the position of the conjoined tendon. We thought that the main cause of this case was Bankart lesion, when we performed the Bankart repair. In addition, because of the existence of grafted bone, we thought open technique should be difficult, so we performed arthroscopic Bankart repair. The follow-up period of this case is short, but satisfactory results are obtained.
