Hip arthroplasty after femoral osteotomy

The authors report the results of 56 prosthetic implants on previous femoral osteotomy. The cases submitted to surgery, some time after the operation, present with clinical-radiographic results (movement and risk of loosening) that are worse than those cases that had not undergone osteotomy. Among complications, a higher incidence of intraoperative fractures and nerve paralysis were observed. Fractures always occurred when instrumentation was removed during the same prosthetic implantation procedure.
