Total hip arthroplasty (T. H. A.) for complete dislocation has many problems. In order to perform the operation safer we attempted to do T. H. A. in two-stage, which consists of resection of the femoral head and skeletal traction of the femur before T. H. A., so as to obtain sufficient information of nerve palsy and of the site to place the socket.Case 1 A 53-year-old house-wife with 5cm dislocation of right hip. Eleven weeks later, the socket dislocated from the pelvis and grafted bone and screws were broken. Satisfactory result was obtained by re-operation with good function of the joint and muscles.Case 2 A 51-year-old male laborer with 8cm dislocation. Reposition was technically quite difficult. Leg discrepancy reduced to 2.5cm, but the abductor weakness remained.
