| 摘 要： | 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。 |

| Abstract: | 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 radi... |
