A 45-year-old woman presented with end-stage osteoarthritis of the left hip. All conservative treatment measures had been exhausted, and she therefore underwent total hip arthroplasty. The patient was positioned in the right lateral decubitus position, and a posterior approach to the hip was used. Successful implantation of a cementless acetabular cup and polyethylene liner was executed (Trilogy; Zimmer). During preparation of the femoral canal for a cementless, modular stem (Fibermetal Midcoat; Zimmer), a complication occurred. After discussion with the family the arthroplasty was completed, and after subsequent discussion with the asymptomatic patient, no further intervention was attempted. Imaging studies were obtained at regular intervals, including at 8 years after the arthroplasty (Figs. 1 and 2-A through 2-D).
