X线数字图像法推断前臂骨折形成时间

A X-Digital image radiographic study deducing the injury time of forearm fracture

目的利用X线数字图像法推断前臂骨折形成的时间。方法收集70例前臂骨折患者随访的620张X线数字图像,根据X线检查骨折愈合评判标准列表,将骨折愈合过程分为5级,利用Photoshop的图像处理和测量功能,对不同年龄组、不同治疗方式的患者骨折愈合过程相关放射学标志进行观察和测量,运用SPSS11.5软件对各级愈合时间进行分析。结果年龄和手术与否分别是影响骨折愈合的独立因素,根据不同年龄、不同治疗方式可以得到各级愈合时间列表。以愈合Ⅲ级的出现时间为例,青年组采用石膏固定治疗的,平均时间为12.2周,采用手术治疗的,需要18周,而少年组采用石膏固定治疗的,则只需5.8周。结论根据骨折愈合过程中X线数字图像指标,对患者进行分组观察,可提高推断骨折形成时间的准确度。

Objective To estimate the injury time and to establish objective evidence of forearm bone fracture by analyzing the digital X-ray radiographs. Methods 620 follow-up radiographs of fractured ulna and/or radius shaft in 70 patients were examined by eyes and assessed qualitatively by means of Photoshop image analysis system. The procedure of fracture healing was classified 5 grades according to the assessment standard of fracture healing by X-ray. The time interval between injury and the appearance of the radiographic signs were analyzed by SPSS 11.5 statistical software among the different groups of therapy and among the different groups of age. Results The age and operative therapy were the independent factors which could affect the development or duration of radiographic features according to the index of fracture healing,therefore the healing time chart were listed among different groups striated by the age and the way of therapy. According to the time chart of grade Ⅲ healing,it was shown that the mean healing time was 12.2 weeks in the group of young by gypsum fixing,18 weeks in the young by operation,and only 5.8 weeks in juvenile by gypsum fixing. Conclusion The injury time of fracture is estimated more accurately by observing the X-radiographic signs of digital image in the different groups of age.
