Biological fixation of hydroxyapatite-coated versus grit-blasted titanium hip stems: a canine study


Abstract Background. The purpose of the study was to evaluate the influence of a proximal hydroxyapatite (HA) coating in comparison with a grit-blasted titanium surface of an anatomic hip stem in an animal model over a maximum duration of 2 years.
