We experienced a rare case of displaced anatomical neck fracture of the humerus with posterior shoulder dislocation.<BR>A 27 year-old male injured his shoulder in a motorcycle accident and was brought to our emergency department. He was diagnosed with posterior shoulder dislocation with humeral anatomical neck and greater tuberosity fracture using X-ray and CT scans. Successful closed reduction of the fracture was obtained under general anesthesia on the day of injury. With the displaced anatomical neck fracture, however, open reduction and internal fixation of the fracture was performed on the eighth day after the injury. The humeral head fragment rotated antero-inferiorly with, firm occlusion of the fracture. After careful reducition of the humeral head fragment, we fixed the fracture with two cancellous screws. At the time of 2.5 years after the operation, the fracture united without humeral head necrosis and the patient fully recovered without any complaint.<BR>As the posterior facet of the greater tuberosity became the third splinter of bone, hinge of the anatomical fracture was limited to the postero-inferior part, and the humeral head fragment displaced antero-inferiorly in this case. Postoperative humeral head necrosis could be avoided with careful preservation of the posterior continuation part. Since the anatomical fracture site was stabilized with rotator cuff after successful reposition, the stability of the fracture could be expected with two screws.
