Abstract : The two primary objectives of this program are: (1) to achieve a direct chemical bond between orthopaedic devices and bone using glass and glass-ceramic materials or coatings, and (2) to develop a scientific understanding of the interfacisl reactions occurring between materials and bone. This report summarizes program accomplishments of the last three years and presents papers concerning: a systems approach to biomaterials; solubility behavior of bioglasses and bioglass-ceramics; mechanisms of direct chemical bonding of bioactive glasses andbioglass-ceramics to cortical beone, cancellous bone and muscle; materials and biomechanics design of a bioglass flame spray coated monkey hip prosthesis and histological reactions at the bone-prosthesis interface after 14 months.
