    摘要: A bone-growth stimulating composition for forming a resorbable implant, methods for making such a composition and a corresponding putty/paste material. In some embodiments of the invention, such a material includes a plurality of particles having a predetermined size and comprising a first calcium sulfate compound and a resorbable polymer in a predetermined weight ratio. Methods for making such a material include rotating calcium sulfate powder in a drum at a first predetermined drum speed, spraying of a resorbable polymer solution at a predetermined rate on the calcium sulfate powder over a predetermined period of time and drying the resulting particles. Such compositions allow resorption rates of the implant composition in vivo to be controlled, and my vary between eight and twenty-four weeks (for example), which can be matched to substantially correspond to a rate of bone growth in a particular application. The implant composition of the present invention can be used for the repair, augmentation, and other treatment of bone.

    摘要: The application discloses a polymeric wrap having one or more osteoinductive formulations, wherein each osteoinductive formulation comprises one or more osteoinductive agent(s). In one embodiment, the osteoinductive formulation(s) is contained within a biodegradable polymer sheet. In another embodiment of the invention, the polymeric wrap comprises at least two or more individual biodegradable polymer sheets or layers optionally comprising osteoinductive formulation(s) comprising at least one osteoinductive agent. The osteoinductive formulations are available in immediate or sustained release formulations. The method further relates to preventing and treating osteolytic lesions formed following implantation of an orthopaedic device or other implant.
