中文摘要: |
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. |
