   Abstract:
   In order to attain bone repair using bone morphogenic proteins (BMP), there is a need for a carrier which can effectively deliver the BMP to the repair site in a controlled fashion and at the same time provide a scaffold for the regenerating tissue to grow upon. The feasibility of using BMP loaded polylactic acid (PLA)/hydroxyapatite (HA) foam fabricated by a novel phase separation technique to induce osteogenesis in an ectopic site in a rat model is demonstrated. Results show that controlled release of BMP from highly porous foams fabricated by the phase separation technique is achieved. Furthermore implantation of these BMP loaded foams in vivo resulted in the ectopic induction of bone and cartilage.
