Abstract

Composite orthopedic devices that facilitate spine stabilization, such as: bone screws, rods, plates, interbodies, and corpectomy cages are disclosed. They are designed to provide both strength and load carrying capabilities, while increasing bio-integration of the devices with the surrounding bone tissue. They are constructed of composite layers of allograft and / or autograft bone and a structural material, such as titanium alloy or carbon / graphite fiber composite. Cannulations within the device are loaded with a mixture of stem cells, particles of allograft and / or autograft bone, and bone growth factors, such as BMP-2. The cannulations are connected to the surface of the device via multiple fenestrations that provide pathways to supply the bone / stem cell mixture to the surface, allowing living bone tissue to grow and insure bio-integration. The devices can also have radiofrequency (RF) stimulation implantation within the structure of the implanted device, capable of responding to external RF stimulation of enhanced bone growth.
