title: Hydroxyapatite coated hip prosthesis followed up for 5 years.
abstract: We prospectively studied 250 patients with a proximal hydroxyapatite coated hip prosthesis. The follow-up period was 5 years. All components showed osseointegration except for one deep infection. The morphology of bone remodeling with either endosteal bone formation or periosteal bone formation was dependent on the way the stem filled the medullary canal. No linear or distal osteolysis around the stems was observed.
