目的：为建立一种客观无损伤的骨折愈合评估方法。方法：用计算机图像处理方法，对４８例成人新鲜骨干骨折、５０例成人陈旧骨干骨折、７０只家兔实验性胫骨骨折的Ｘ线片进行分析。结果：骨痂力学强度与骨痂Ｘ线灰度呈指数相关（Ｐ＜０．０５），骨痂Ｘ线灰度随骨折愈合的进程而增高。结论：骨力学强度特性与骨痂Ｘ线灰度密切相关，为中西医结合治疗骨折提供了一个客观的新的疗效评估方法。

英文摘要:

To set up an objective and non-injury method to estimate the fracture healing process. Methods: Xray films of 48 cases of adult fresh fracture,50 cases of adult old fracture and 70 rabbits experimental fracture of tibia were analysed,through computer image processing. Results: The bending strength of callus and the X-ray density of callus have an exponential correlation(P<0.05). The X-ray density of callus increased coincidently with the fracture healing process. It also confirmed that there was a high correlation between the character of bending strength of callus and the X-ray density of callus. Conclusion: It provided an objective method to assess fracture healing treated by the integration of TCM and WM.
