We have treated operatively two patients with a large, displaced anteroinferior glenoid rim fracture. One is a 60 year old man, and the other a 55 year old man. The causes of trauma were falls on the ground.<BR>For obtaining a field of view, we transected the coracoid process temporally. After the anterior part of the glenoid was repaired, the fragment of coracoid process was reduced anatomically, and fixed with a cancellous bone screw. About one week after the operations, the fragments of coracoid process were detached distally with a screw. So we had to reoperate. In the reoperation, we transferred the coracoid process on the glenoid neck with a screw.<BR>Various factors may be responsible for displacement of the coracoid process fragment. It is probably because the simple small lag screw is inadequate for stability. The re-attached coracoid process is always pulled powerfully by the conjoined tendon.<BR>In conclusion, we should have done alternative augmentation for the fixation of the coracoid process. Late middle aged men may be indicated for the Bristow method from the very start.
