Radiological Evaluation of the Femoral Component Fixed with Interface Bioactive Bone Cement in Revision Total Hip Arthroplasty

Thirty cases whose femoral side was operated with interface bioactive bone cement technique in revision total hip arthroplasty for aseptic loosening and followed for more than 6 years were evaluated. The present study includes 2 men and 28 women with an average age at operation of 60 years. Mean postoperative follow-up period was 9 years. Rerevision of femoral component was not found. Possible loosening was observed in 1 case, using the criteria of Harris. Among 21 cases whose cementing grade was assessed as B or C in postoperative x-ray, radiolucent line at bone-cement interface has disappeared before last follow-up in 11 cases. The present study revealed that the good result was obtained using the interface bioactive bone cement technique for reconstruction of aseptic femoral loosening.
