Failure of femoral component in total hip arthroplasty: a case study--failure analysis.
Marked bending prior to fatigue failure of the femoral component of a total hip arthroplasty points out the necessity for proper valgus placement of the prosthesis in the femoral shaft, especially in large active patients. This failure also indicates the need for limiting activities in such a patient.
