title: Arthroscopic repair of inferior labrum from anterior to posterior lesions associated with multidirectional instability of the shoulder.
abstract: Multidirectional instability (MDI) of the shoulder may arise spontaneously; however, recent evidence suggests that traumatic events may play a role in this syndrome. Variable degrees of injury around the circumference of the glenoid have been reported, ranging from Bankart and Kim lesions to 270° of injury and even 360° of injury. Hyperabduction injury may cause inferior subluxation of the shoulder and result in traumatic isolated injury to the inferior labrum from anterior to posterior. This particular lesion spans approximately 180° of the inferior hemisphere and may lead to symptomatic MDI. In contrast to open or arthroscopic plication procedures for atraumatic MDI without labral injury, the goal in these cases is anatomic arthroscopic repair of the inferior labrum tear without the need for capsular plication, volume reduction, or rotator interval closure.
