It has been emphasized that the choice of treatment for the trochanteric fracture of the femur is open reduction and stable internal fixation to reduce complications by early ambulation.

Recently dynamic hip screws(DHS) are very popular to the treatment of trochanteric fracture of the femur but they have some complications. Postoperative complications of the trochanteric fracture of the femur include malunion, delayed union, nonunion, disengagement of lag screw from sideplate, metal failure and the screw cutting-out of the femoral head, but subluxation of the hip has not reported as a complication.

We experienced a rare case of trochanteric fracture which was treated with open reduction and internal fixation with DHS and was found to be subluxation of its hip at postoperative 4 weeks, which was managed by cemented bipolar endoprethesis.
