  • Title: Detecting stem debonding in total hip arthroplasty.
    Author: McGrory BJ, Evans P, Duffy G.
    Journal: Am J Orthop (Belle Mead NJ); 2005 Aug; 34(8):400-1. PubMed ID: 16187733.
    Abstract:
    In total hip arthroplasty, cemented femoral components combined with contemporary insertion techniques have an excellent track record of reliable long-term success. Certain cemented stem designs, however, have high failure rates. As osteolysis and bone destruction are rapid and progressive with certain designs, early detection of failure is imperative. We describe a case in which the common failure pattern of debonding is evident after radiographic evaluation with stress application. Although a single-leg stance was used in this case, a modified standing view might also be used.
