Hybrid Total Hip Arthroplasty: State-of-the-Art in the New Millennium?

$25.00

Clinical results from the past 30 years have proven total hip arthroplasty (THA) to be an effective technique for treating arthritic and degenerative conditions of the hip. Though there is little question concerning the effectiveness THA in general, significant debate exists concerning the best technique for performing the procedure. Sir John Charnley’s concept of low-friction arthroplasty (LFA), considered to be the gold standard for THA, employs a cemented fixation technique for both the femoral and acetabular components. Over time, the merits of cemented fixation have been called into question as significant percentages of LFA implants failed and required revision surgery. Hybrid total hip arthroplasty is a variation of LFA that employs cemented fixation of the femoral component with cementless fixation of the acetabular component. Intermediate-term clinical results of hybrid THA have shown it to be a promising technique, with revision rates of both the femoral and acetabular components superior to Charnley LFA studies at similar lengths of follow-up. Though these results are encouraging, long-term data from the hybrid THA studies are required before a conclusion can be made as to whether the hybrid method is in fact superior to the LFA technique for performing THA.
