摘　　要：本文观察了夹板和髓内针固定条件下家兔胫骨骨折端间隙在骨折愈合过程的变化。通过光导纤维法观察和图像处理系统分析测量，Ｘ线片观察骨痂形成，结果显示骨折端间隙均值随骨折时间增加而逐渐减小，骨折端活动变化趋势与骨折后时间和肢体负重功能密切相关（Ｐ＜０．０１）。Ｘ线片显示６周时均有桥梁外骨痂桥架于骨折端而愈合。研究结果揭示实验性家兔胫骨骨折端纵轴位移在０．３３±０．１７～０．９５±０．４３ｍｍ范围内对骨折愈合有利。In this article, changes of the healing process of rabbit tibial interfragmental gap treated with small splints and intramedullary nail fixation were observed. Through light guide fiber method, image pattern analysis measurements and radiographic analysis of the callus, the results showed that the mean value of fracture interfragmental gap decreased along with increasing of the time. There are also correlation between the tendency of changes of fracture and post-fracture time and burden of the limb (p<0.01). Roentgenogram showed that the fractures were healed by the external bridge callus across the fracture site at sixth week. The results suggested that longitudinal displacement within 0.33±0.17-0.95±0.43mm of the experimental rabbit tibial fracture ends can facilitate bone healing.
