Abstract:
Twenty-four New Zealand rabbits were used in the experiment. Four animals served as control and the other 20 were fixed by stainless—steel plates on their left tibia to induce the local osteoporosis. The plates were removed 2 monthes after implantation. Four animals were killed immediately following the plate removal and the others were sacrificed 1, 2, 3 and 4 months later, respectively. The cortical bone beneath the plates were prepared for transmission electron microscopy observation. The results indicated that the recovery process of the local osteoprosis after the rigid plate removal mainly manifested the decrease in bone resorption and the increase in bone formation, which included osteoblastic and osteocytic.
