A radiological follow-up study of plasma sprayed bovine hydroxyapatite (BHA) coatings

Abstract

In this study a short follow-up study of plasma sprayed stainless steel femoral implants in dogs was performed. Because of its excellent biologic properties, hydroxyapatite (HA) has been required widely in orthopaedic surgery. In this study HA has been used on metal in a form of a thin coating. The HA material has been derived from calcined (850degreesC) bovine bone. The bovine HA (BHA) which was produced had nearly the same mechanical properties when compared with the a commercial type HA (CHA) that was investigated in a recent research, that is available in literature There were not any vital complications observed postoperatively after 1.5 month of implantation. The long-term follow-up investigations of this study should be carried out in the future.
