Current treatment of bone defects due to trauma, cancer, or degenerative spine diseases involves the implantation of a bone graft. Autografts, which are harvested from the patient's own body, are associated with problems of limited availability and surgical morbidity. The use of allografts obtained from donors is also not desirable due to the risks of disease transmission and the costs of maintaining bone banks. The ideal solution would be to regenerate native bone to fill the defects. A group of potent growth factors known as bone morphogenetic proteins (BMPs) have been hailed as alternatives to bone grafts due to their ability to elicit new bone formation. Clinical use of BMPs involves loading the protein solution onto collagen sponges and subsequent implantation. However, these conventional collagen carriers show rapid clearance of BMPs within [approx.] 2 weeks, whereas bone healing is a longer process, especially in higher mammals. The poor BMP retention in collagen sponges may explain the greater response variability in higher mammals, ranging from full bone bridging within weeks to no bone union. These sponges are also not capable of tunable or multifactor release that could benefit healing in certain anatomic sites, e.g. avascular sites and prolonged non-unions. Hence...
