Their paces were improved obviously and the function of their hips was satisfactory.</p><p><b>CONCLUSIONS</b>The treatment by total hip arthroplasty and the shorting of posterior femoral is effective and efficient for osteoarthritis secondary to Crowe IV development dysplastic hip in adults. The long-term followup is necessary for further study.</p>
