Per Fix HA型人工股関節置換術の短期成績

抄録

We present the results of 36 total hip arthroplasties using Per Fix HA Prosthesis with a mean follow-up period of 19 months (range; 6 to 45 months). The average Japan Orthopaedic Association hip score increased from 45.7 points prior to the operation to 85.1 points at the last follow-up. All radiographs were examined for the presence of initial gap, reactive line, radiolucent line, osteolysis and loosenig. Our radiological results showed that the HA coating can provide durable implant fixation.
