Fig. 1Classification of greater trochanteric fracture. (A) Type A is a transverse fracture above the inferior border of greater trochanter (GT). The fracture fragment was displaced superiorly by the pulling force of the hip abductors. (B) Type B is a vertical fracture that is not extended to the inferior border of GT. Type B was similar in stability of fracture fragment to type A. (C) Type C is the transverse fracture below the inferior border of GT. Type B fracture was more stable than type A because of the balanced pulling forces of abductors proximally and vastus lateralis distally. (D) Type D is a vertical fracture that extended to below to inferior border of GT. Type D was similar in stability of fracture fragment to type C. The muscles were attached to the fracture fragment proximally and distally, which stabilized the fracture.
