Arthroscopic reduction and internal fixation for displaced anterior glenoid rim and greater tuberosity fractures

Abstract

Concomitant fractures of the greater tuberosity and anterior glenoid rim are rare in cases of traumatic anterior dislocation of the shoulder. In such cases, open reduction and internal fixation for both fractures have been tried. However, the extensive dissection required to visualize fracture fragments may contribute to postoperative shoulder stiffness and morbidity. Recent advancements in arthroscopy suggest that the arthroscopic treatment of these fractures appears to be a feasible and attractive challenge. For anterior glenoid rim fractures, techniques described include arthroscopic screw fixation and the Bankart repair technique with suture anchors [1–3]. Recently, a double bony row technique and a bridge technique were developed to increase the primary stability of arthroscopic fixation [4]. For greater tuberosity fractures, techniques described also include arthroscopic screw fixation and suture anchor fixation [5, 6], and techniques for arthroscopic internal reduction and fixation of greater tuberosity fractures using double-row or suture-bridge techniques have recently been described [7, 8]. We present a rare case of anterior dislocation of the shoulder with displaced anterior glenoid rim and greater tuberosity fractures. Few reports have been issued on the simultaneous treatment of both fractures using arthroscopic techniques. In fact, to our knowledge, this is the first case in which both glenoid and tuberosity fractures were repaired using arthroscopic techniques and cannulated screws. The patient provided consent for his case to be submitted for publication.
