The radiographic evaluation of fracture healing in the long bones utilizes subjective and hardly analytic standards. Therefore, to solve this problem, the authors suggest using a computerized image processing system which increases radiographic informative content and allows an objective evaluation of fracture healing. We analyzed the radiographs of 15 patients suffering from femoral fracture and treated by means of Küntscher nailing. We processed the radiographs taken both before and 1, 2, 4, and 6 months after surgical treatment. It was thus possible to select the regions of interest, to graph brightness levels and to measure both distances and areas. Computerized image processing provides an objective and quantitative analysis of radiographs and allows an increase in informative content. It also allows the comparison of pre- and postoperative radiographs with those taken at different times. Our results may confirm the utility of computerized image analysis of radiographs to evaluate bone remodelling during fracture healing.
长骨骨折愈合情况的影像学评估采用的是主观且几乎无法分析的标准。因此，为解决这一问题，作者建议使用计算机图像处理系统，该系统可增加影像学信息含量，并能对骨折愈合情况进行客观评估。我们分析了15例股骨干骨折患者采用Küntscher髓内钉治疗后的X线片。我们对手术治疗前、术后1个月、2个月、4个月和6个月拍摄的X线片进行了处理。这样就能够选择感兴趣区域、绘制亮度水平图以及测量距离和面积。计算机图像处理可对X线片进行客观定量分析，并能增加信息含量。它还能将术前和术后的X线片与不同时间拍摄的X线片进行比较。我们的结果可能证实了对X线片进行计算机图像分析在评估骨折愈合过程中骨重塑情况方面的实用性。
