[Quantitative study on the osteogenic potential of vascularized iliac periosteal]

The effect of pedical blood supply, recipient environment, blood supply to the osteogenic capacity of iliac periosteal was investigated. An iliac periosteal flap based on the circumflexa femoris lateralis vessels was developed in a canine model. The vascularied iliac periosteal was rotated onto the quadriceps femoris musculus or epigastrica inferior fibrous-connective tissues in one side and the free flap was done in the same way in another side. 2, 2, 4, 6 animals were killed at 2, 4, 8, 12 week after operation and the flaps were studied by new bone Ca, P content, bone dense measure, double tetracycline labeling, bone histomorphometry analysis and light microscopy. The following results were obtained: (1) Iliac periosteal has good osteogenic capacity; (2) The early good blood supply is much more important than the recipient environment blood supply, it make the bone formation speed 2-4 weeks forward.
