Dorsal dislocation occurs in 80% of all fracture dislocations of the elbow joint. In 10-15% of these njuries the coronoid process and the radial head are involved. If this injury causes the defect of the radial head - which means the loss of the main supporting part of the joint, - it is only the coronoid process which gives stability to the elbow joint. Therefore, in cases of coronoid fracture it is of utmost importance to reconstruct the coronoid process, if the fracture involves more than 1/6 of the incisura olecrani. Advisable for fixation is the use of a lag screw. In some cases the reconstruction with autogenous bone graft or osteotomy of the olecranon is indicated.
肘关节骨折脱位中80%为背侧脱位。在这些损伤中，10% - 15%累及冠状突和桡骨头。如果这种损伤导致桡骨头缺损——这意味着关节主要支撑部分丧失，那么只有冠状突能为肘关节提供稳定性。因此，在冠状突骨折的情况下，如果骨折累及鹰嘴切迹超过1/6，重建冠状突至关重要。建议使用拉力螺钉进行固定。在某些情况下，需要采用自体骨移植或鹰嘴截骨进行重建。
