Shoulder joint dislocation has the most common incidence rate compare compared to other joints. It is reported that shoulder Shoulder dislocation couldmay be associated with glenoid rim, greater tuberosity of humerus and coracoid process fracture. There were have only been 2 cases of anterior shoulder dislocation simultaneously combined with simultaneous glenoid rim, coracoid process, and humerus greater tuberosity fracture worldwide and no report reports in Korea. We present a case of quadruple fracture (glenoid rim, coracoid process, greater tuberosity, surgical neck of humerus) associated with anterior shoulder dislocation and treated successfully by open reduction. In addition, with we provide the injury mechanism, diagnosis, treatment procedure and discussion.

Fig. 1
Shoulder plain radiographs anteroposterior (A) (arrow: displaced surgical neck fracture, arrowhead: displaced tuberosity fragment), lateral (B) demonstrate anterior shoulder dislocation with glenoid rim, coracoid process, greater tuberosity of humerus, and surgical neck fracture.
Fig. 2
Three-dimentional reconstruction of shoulder computed tomographies shows 3-part proximal humerus fracture (arrow: displaced surgical neck fracture, arrowhead: displaced tuberosity fragment).
Fig. 3
Glenoid fracture (A) was shown and glenoid bone defect (B) was evaluated based on 3-dimentional reconstruction of shoulder computed tomography (arrow: percentage of glenoid defect).
Fig. 4
Immediate postoperative plain radiographs anteroposterior (A), axial (B) view were assessed.
Fig. 5
Plain radiographs anteroposterior (A), lateral (B) 3 months after initial surgery show bony union around proximal shoulder, but malunion of the coracoid process.
