背景：Mimics软件是一种基于CT扫描数据的三维图像处理和编辑工具，可以将CT、MRI以及超声人体扫描后得到的数据及图像经过专业化处理重建成三维图像，并在计算机屏幕上立体显示，从而帮助临床医师直观的了解骨折的类型及周围组织的三维结构关系，对骨科手术的开展提供了很大的帮助。目的：探讨Mimics软件三维重建在Pilon骨折围手术期的应用效果。方法：选取2008年9月至2013年9月中山市小榄人民医院拟行内固定治疗的Pilon骨折患者61例为研究对象，按入院时间先后排序随机分为三维组和对照组。两组患者入院后均行踝关节正侧位X射线片检查以及多排螺旋CT扫描，对照组结合检查结果开展内固定治疗，三维组患者在对照组患者基础上利用MimicsⅤ10.0软件进行三维实体重建后开展内固定治疗，对比两组患者的手术时间以及治疗后随访时的功能疗效情况。结果与结论：三维组手术时间明显短于对照组，差异有显著性意义(P<0.05)。三维组治疗后6个月功能疗效评价为优的患者明显多于对照组，功能疗效评价为差的患者明显少于对照组，三维组治疗后6个月的功能疗效总体优于对照组，差异有显著性意义(P<0.05)。提示在Pilon骨折围手术期应用 Mimics软件三维重建，可全面评估骨折情况，优化和完善术前计划，降低了风险，从而促进内固定治疗顺利完成。%BACKGROUND:Mimics software is a three-dimensional (3D) image processing and editing tool based on CT scan data. Mimics software can rebuild the data and images gotten in CT, MRI and ultrasound scans into 3D images and display on the computer screen so as to help clinicians understand the type of fracture and the relationship of the 3D structure of the surrounding tissue and to provide a great help in the development of orthopedics operation. OBJECTIVE:To explore the application effect of Mimics software 3D reconstruction on perioperative period of Pilon fracture. METHODS:This study selected 61 cases of Pilon fracture, who received the surgery in the Zhongshan City Xiaolan People’s Hospital from September 2008 to September 2013, as research objects. They were randomly divided into 3D group and control group in accordance with the time of admission. Al patients underwent anterioposterior and lateral X-ray film examination and multi-slice spiral CT scan. Patients in the control group received internal fixation according to above examination results. Patients of the 3D group, on the base of those of the control group, were subjected to internal fixation after three-dimensional entity reconstruction by using Mimics V 10.0 software. Operation time and functional curative effect in the postoperative folow-up were compared between the two groups. RESULTS AND CONCLUSION:The operation time was significantly less in the 3D group than in the control group (P < 0.05). The number of patients with excelent 6-month functional curative effect was more, and the number of patients with poor effect was less in the 3D group than in the control group. The 6-month functional curative effect was better in the 3D group than in the control group (P < 0.05). These results showed that the application of Mimics software 3D reconstruction to the perioperative period of Pilon fractures can give comprehensive assessment of the situation of fracture, optimize and improve the preoperative plan and reduce the risk of surgery, and promote the successful completion of internal fixation.
