Fatigue failure of newer generation modular revision femoral stem following fracture healing a case report

摘要

Mechanical failure of the femoral component following total hip arthroplasty is a relatively uncommon complication that has been previously well-described in the literature. Modular, cementless implants have become a popular option in revision total hip arthroplasty. They offer the distinct advantage of optimizing joint kinematics through varying the degree of version, offset, and leg length. We report the case of early fatigue fracture of the Restoration (Stryker, Mahwah, NJ) femoral prosthesis. The following is a detailed description of this case. This report details the events surrounding stem failure, and the technique of reconstruction used to deal with this failure
