Abstract:
Objective To investigate the osteogenesis capability of different frequency extracorporeal shock wave.Methods 39 rabbits received different frequency extracorporeal shock wave at the middle potion of tibia for 3 or 7 days,these rabbits were then sac rificed and the tibia bones were collected to process for HE and toluidine blue staining,the pathological changes were observed under the light microscope.Results After different frequency extracorporeal shock wave treatment,the typical periosteal reaction were observed,external periosteum bleeded and thickened but there was no reaction at internal periosteum,marrow cavity opened and fibrosed.the osteoblast-1iking cell proliferated,however,no cartilage cells were observed;The rabbits received 7 days shock wave treatment showed more severe reaction than those for 3 days.The shock wave at lower frequency showed more severe reaction than higher frequency.Conclusion shock wave induced osteogenesis through the periosteal reaction of external periosteum;the osteogenesis capability of different frequency extracorporeal shock wave were affected by the frequency.Higher frequency of shock wave was not the ideal way to promote osteogenesis.
