Fracture of an Exeter Femoral Stem With Extensive Ipsilateral Periacetabular Osteolysis

Year: 2024

Type: article

Abstract: 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. A revision total hip arthroplasty was performed, including periacetabular bone grafting for extensive osteolysis along with retention of a stable acetabular component. This case highlights the rare complication of Exeter stem fracture as well as the technique of bone grafting a large periacetabular defect with a retained acetabular component. This is of particular interest given the rarity of this event and the resurgence in North America of cemented femoral components in total hip arthroplasty.
