【摘要】：[目的]探讨如何运用计算机对Taylor外固定支架系统所需参数进行精确测量,以便其对胫腓骨骨折畸形进行精确矫正。[方法]收集2015年6月~2016年5月在本院用Taylor外固定支架进行治疗的胫腓骨骨折患者24例。其中,男22例,女2例,年龄14~58岁,平均(37.10±13.90)岁。将所有患者随机分为传统组、计算机辅助组。传统组应用传统的标准测量法采集参数;计算机辅助组应用计算机辅助测量法采集参数。术后拍摄标准的正侧位胫腓骨全长X线片,传统组采用游标卡尺在X线片上直接测量;计算机辅助组在取得DICOM格式文件后导入到Coreldraw X7软件中进行分析。并对计算机辅助组患者的双侧胫腓骨行CT断层扫描,取得DICOM格式文件后导入到Mimics 10.1软件中进行三维重建,最后根据Taylor三维空间外固定支架系统所需参数,在Coreldraw X7和Mimics 10.1软件中进行测量。将测量所得参数输入特定软件,根据电脑软件出具的电子处方开始每日分3次调节Taylor外固定支架上的6根带刻度的螺杆。[结果]全部患者均得到了较好的骨折复位,均达到功能复位标准。传统组患者正位X线片中位移改善度为59.56%,角度改善度为72.76%;侧位X线片中位移改善度为56.31%,角度改善度为57.44%。计算机辅助组患者正位X线片中位移改善度为70.17%,角度改善度为81.02%;侧位X线片中位移改善度为67.41%,角度改善度为70.32%。通过利用计算机进行辅助测量,较精确的得到了各项相关参数,计算机辅助组患者的复位效果优于传统组。[结论]利用计算机辅助测量能精确的定义Taylor外固定支架系统所需各项参数,对骨折畸形进行精确矫正,有利于骨折愈合及患肢功能恢复。
[Abstract]:[objective] to study how to use computer to accurately measure the parameters of Taylor external fixator system in order to correct tibia and fibula fracture deformity accurately. Methods: from June 2015 to May 2016, 24 patients with tibia and fibula fractures were treated with Taylor external fixator in our hospital. There were 22 males and 2 females, aged 14 to 58 years, with an average age of 37.10 卤13.90 years. All patients were randomly divided into traditional group and computer-assisted group. The traditional standard measurement method is used to collect the parameters in the traditional group and the computer aided group to collect the parameters by the computer aided measurement method. The standard full-length radiographs of tibia and fibula were taken after operation. In the traditional group, the Vernier calipers were directly measured on the X-ray slices, and the computer-aided group was imported into the Coreldraw X7 software after obtaining the DICOM format files for analysis. The bilateral tibia and fibula of the computer-assisted group were scanned by CT, the DICOM format files were obtained and imported into the Mimics 10.1 software for 3D reconstruction. Finally, according to the parameters required by the Taylor three-dimensional external fixation stent system, the CT scan was performed on the bilateral tibia and fibula of the patients in the computer-assisted group. The measurement was carried out in Coreldraw X 7 and Mimics 10.1 software. According to the electronic prescription issued by computer software, the measured parameters are input into specific software, and the six graduated screws on the Taylor external fixator are adjusted three times a day. [results] all the patients got better reduction of fracture, all of them reached the standard of functional reduction. In the traditional group, the improvement degree of displacement was 59.56, the degree of angle improvement was 72.76, the degree of improvement of displacement in lateral X-ray was 56.31, the degree of angle improvement was 57.44. In the computer-assisted group, the improvement degree of displacement was 70.17, the degree of angle improvement was 81.02, the degree of improvement of displacement in lateral X-ray was 67.41, the degree of angle improvement was 70.32. By means of computer aided measurement, the relative parameters were obtained accurately, and the reduction effect of computer-assisted group was better than that of traditional group. [conclusion] the parameters of Taylor external fixation system can be accurately defined by computer aided measurement, and the fracture malformation can be corrected accurately, which is beneficial to fracture healing and functional recovery of the affected limb.
