【摘要】：[目的]探討如何運用計算機對Taylor外固定支架系統(tǒng)所需參數(shù)進(jìn)行精確測量,以便其對脛腓骨骨折畸形進(jìn)行精確矯正。[方法]收集2015年6月~2016年5月在本院用Taylor外固定支架進(jìn)行治療的脛腓骨骨折患者24例。其中,男22例,女2例,年齡14~58歲,平均(37.10±13.90)歲。將所有患者隨機分為傳統(tǒng)組、計算機輔助組。傳統(tǒng)組應(yīng)用傳統(tǒng)的標(biāo)準(zhǔn)測量法采集參數(shù);計算機輔助組應(yīng)用計算機輔助測量法采集參數(shù)。術(shù)后拍攝標(biāo)準(zhǔn)的正側(cè)位脛腓骨全長X線片,傳統(tǒng)組采用游標(biāo)卡尺在X線片上直接測量;計算機輔助組在取得DICOM格式文件后導(dǎo)入到Coreldraw X7軟件中進(jìn)行分析。并對計算機輔助組患者的雙側(cè)脛腓骨行CT斷層掃描,取得DICOM格式文件后導(dǎo)入到Mimics 10.1軟件中進(jìn)行三維重建,最后根據(jù)Taylor三維空間外固定支架系統(tǒng)所需參數(shù),在Coreldraw X7和Mimics 10.1軟件中進(jìn)行測量。將測量所得參數(shù)輸入特定軟件,根據(jù)電腦軟件出具的電子處方開始每日分3次調(diào)節(jié)Taylor外固定支架上的6根帶刻度的螺桿。[結(jié)果]全部患者均得到了較好的骨折復(fù)位,均達(dá)到功能復(fù)位標(biāo)準(zhǔn)。傳統(tǒng)組患者正位X線片中位移改善度為59.56%,角度改善度為72.76%;側(cè)位X線片中位移改善度為56.31%,角度改善度為57.44%。計算機輔助組患者正位X線片中位移改善度為70.17%,角度改善度為81.02%;側(cè)位X線片中位移改善度為67.41%,角度改善度為70.32%。通過利用計算機進(jìn)行輔助測量,較精確的得到了各項相關(guān)參數(shù),計算機輔助組患者的復(fù)位效果優(yōu)于傳統(tǒng)組。[結(jié)論]利用計算機輔助測量能精確的定義Taylor外固定支架系統(tǒng)所需各項參數(shù),對骨折畸形進(jìn)行精確矯正,有利于骨折愈合及患肢功能恢復(fù)。
[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 鹵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.
