Arthroscopic autologous bone graft with arthroscopic Bankart repair for a large bony defect lesion caused by recurrent shoulder dislocation.

Abstract

Many clinicians believe that a large bony defect of the glenoid must be treated with bone grafting when a Bankart procedure is performed. Various types of bone graft, such as open bone graft, Eden-Hybinnette, J-bone graft, coracoid transfer, and Latarjet, have been used. These require open procedures that are difficult to perform arthroscopically. We performed an arthroscopic autologous bone graft and an arthroscopic Bankart repair at the same time to treat a patient with recurrent dislocation of the shoulder joint and a large bony Bankart lesion. We harvested from the lateral site of the acromion 2 bones that were 2.7 mm in cylindrical diameter. We transplanted these bones to the large bony defect of the anteroinferior area of the glenoid and placed anchors between the 2 plugs. During the 30 months since the surgery was performed, the patient has not experienced dislocation or apprehension about the shoulder. A 3-dimensional computed tomography scan showed enlargement of the glenoid surface. Our surgical procedure offers promise for treatment of patients with recurrent dislocation of the shoulder joint and a large bony Bankart lesion because it allows the surgeon to alter the size and the grafted site of the cylindrical bone according to the size of the defect.
