Abstract
42 cases with fractures of the proximal end of the humerus were treated by osteosynthesis using the hook plate.
All cases achieved bone union. In the 26 cases that we could evaluate, the average JOA score was 84. 1 points, and the average flexion angle was 152.3°.
This method is useful for the treatment of fractures of the proximal end of the humerus, even in cases with dislocation, displaced fragments, or osteoporosis.
