Abstract
Objective: To evaluate the osteogenetic activity of hydroxylapatite combined with freezed-dried fetal bone (HA/FDFB). Methods:Biolateral tibia defects were created in sixten adult rabbits. Left defects were filled with HA alone, and the right defects were filled with HA/FDFB. Animals were sacrified at 1. 4.12 and 24 weeks postoperation. The tibia specimen were assessed byradiograph and light macroscopy.Results: No bone formation was o bserved except for a few section gathered from the lates stage in theleft defects. Most part of space between the HA particles was filled with fibrous connective tissue during the experiment. However, alittle new bone had formed at 4 weeks postoperation in the right defects. 12 weeks later, woven bone penetratedalmost the wholeblock of HA. The newly formed bone completely filled the space of the rnass of HA and showed a lamella bone appearance at 24 weekspostoperation. Conclusions: This study indicated at that HA combined with FDFB showed a highly osteogenetic activtiy and could playa role in promoting bone repairing关键词
