ABSTRACT
To research a new method to treat the fracture and nonunion of the region from anatomical neck to the diaphysis part of the proximal humerus. According to the mechanical character of bio memory material Nitional and the physiological character of proximal humerus, a new device called proximal humerus memory connector was designed. 22 cases of comminuted fracture, malunion and nonunion of proximal humerus were treated by this device. The healing style was characterized by plate bone substitution, no disordering callus was observed. The function of the shoulder was scored average 88.5 according to the criteria of Michael Reese. PHMC is an efficacious method to treat every type fractures and nonunion of the region from anatomical neck to the diaphysis part of humerus, and a new way is explored to reduce the rate of prostheses displacement of this part.
