Patent ID: 6887272

Claim:
An artificial vertebra system having a bone-marrow regenerating function and being transformable to an autologous bone, comprising a hydroxyapatite (HAp)/collagen (Col) composite body formed by pressure-dehydrating a coprecipitate of hydroxyapatite and collagen to have the weight ratio of HAp to Col ranging from 70:30 to 80:20 which is equivalent to that of a bone, and a nanocomposite structure in which HAp particles are conjugated along a Col fiber while aligned each of the c-axes of said HAp particles along said Col fiber, said HAp/Col composite body being formed with a perforated aperture for allowing a blood vessel and an osteogenic cell to intrude thereinto, said aperture being perforated in the frontward/rearward direction and rightward/leftward direction relative to the front side of a human body in a configuration analogous to that of a Volkmann's canal, wherein a plural number of said apertures are arranged at even intervals.
