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。
[Objective] To investigate outcomes of computer-aided adjustment of Taylor spatial frame for treatment of tibiofibular fracture. [Methods] From June 2015 to May 2016, 24 patients with tiabiofibular fracture, including 22 male and 2 female, aged from 14 to 58 years with an average of 37.1±13.9 years, were treated with Taylor spatial frame, which was adjust- ed for improvement of reduction ＂after surgery. Of them, the patients who had a direct measurement with caliper on X ray film were assigned as the traditional group, while the patients who had computer-aided measurement were termed as the computer- aided group, which were conducted with Coreldraw X7 software for DICOM format files of X-ray films and Mimics 10.1 software for the bilateral tibiofibula CT scans. The Taylor spatial frames were respectively adjusted 3 times every day according to the da- ta directly measured with a caliper, or obtained from computer software after surgery. [Results] After adjustment of the frames, the residual deformities were corrected well in all of the 24 patients, to meet the standard of function restoration. The traditional group was significantly inferior to tile computer-aided group in the improvement rate of displacement in anteroposte- rior （AP） position （59.56% vs 70.17%, P=？）, angle in AP position （72.76% vs 81.02%, P=？） , displacement in lateral position （56.31% vs 67.41%, P=？）, and angle in lateral position （57.44% vs 70.32% P=？） . [ Conclusion ] The computer-aided measure-ment does get the precise data for adjustment of Taylor spa- tial frame to correct the residual deformities more accurately.
