RESUMEN
<p><b>OBJECTIVE</b>To discuss the effective method and outcome to old femoral neck fracture with severe hip joint dislocation.</p><p><b>METHODS</b>From April 1996, 7 cases of old femoral neck fracture with severe hip joint dislocation were treated by the shorting of posterior femoral and total hip arthroplasty.</p><p><b>RESULTS</b>The average age of 7 patients was 51 years old and the mean follow-up was 27.3 months. The mean Harris score was improved to 84.3 from 36.7 before operation in the latest follow-up. The prosthesis position of acetabular and femoral was excellent, there was no sinking or softening of artificial joint, nonunion of femoral osteotomy.</p><p><b>CONCLUSION</b>The preliminary clinical results are quite satisfactory of the shorting of posterior femoral and total hip arthroplasty to old femoral neck fracture with severe hip joint dislocation, the follow-up is necessary for further long-term outcome.</p>
