Fracture of an Exeter Femoral Stem With Extensive Ipsilateral Periacetabular Osteolysis.

The Stryker Exeter stem (Stryker, Kalamazoo, MI) has been in service for over 50 years and remains the most widely used cemented stem. Stem fracture is a rare complication, with recently reported rates of 1 in 10,000. We present a case of Exeter stem fracture 25 years following initial implantation as well as a large periacetabular defect secondary to osteolysis.
