METHODS Out of 20 rabbits, 2 rabbits were used to observe normal radius vascular and 18 rabbits were inserted by autogenous periosteal pieces in the bone defect models. The animals were sacrificed on the 3rd, 5th, 7th day and at the 2nd, 4th, 8th and 12th week after operation, respectively. Then microvascular reconstruction was surveyed. RESULTS On the course of repairing bone defect, the newborn vascular had following orderly changes of forming vascular bud, brush like blood vessel, branch like vessel, no vascular cartilage, bunch like vessel, spongy vessel and reticular vessel. CONCLUSION On the different stages of periosteal piece transplantation for repairing bone defect, the newborn blood vessels have its own special appearances.
