Abstract
We reviewed 78 patients with Hylamer acetabular liners (DePuy-Dupont Orthopedics, Warsaw, IN), with a mean follow-up of 3.8 years (range, 2-6 years), for signs of osteolysis secondary to polyethylene wear. Nine patients (11.5%) showed osteolysis greater than 1 cm2. One patient had a greater trochanter fracture through a lytic area, one patient required a revision at 4 years for severe acetabular and femoral lysis with lesser trochanter fracture, and a second patient is awaiting revision.
