bone fixation or augmentation in a mammalian body to enhance the mechanical strength of a fracture is provided by reinforcement fixing bone ends together using the implant device . a resorbable device can be rendered anti - osteolytic by incorporating materials such as bisphosphonates . it can also be rendered osteoconductive by the incorporation of an osteoconductive material such as bioactive glass or tcp . the implant device has a matrix as one phase , where the matrix is made of a bioresorbable polymer . one phase of the implant is made from self - reinforcing elements and the matrix contains an antiosteolytic agent component . the implant contains further osteoconductive and / or osteoconductive material .
