Abstract:
Objective To study the effect of operation on transplanted fibula healing,which repaired long and thick and burnden bone defects by two fibula compound transplanation under periosteum with vascular loop. Methods Seventy-two healthy rabbits were divided randomly into three groups.Group A is the mono-fibular transplanation group;group B,the double fibular transplanation extra-periosteum and group C,the double fibular transplanation under-periosteum.Each group consisted of 24 rabbits.Animal models of 10mm tibial defects were established and three operation patterns were performed.the serum were obtained to determine the level of ALP and BGP bone and mineral density and biomechanic index at 2,4,8,12,16 weeks.4 rabbits of each group were examined roentgenographically and histologically.the condition of the bone healing and contour were observed.The different effects of each operation were compared with such observation index. Results The X-ray showed that the area of the external callus were larger in C groups than that in A,B and eht bone trabecula were in order,the fibula showed significant bone hypertrophy.the serum ALP,BGP and mineral density level were higher in C group than that in A,B.the difference has statistical significance (P
