To establish a computer-aided three-dimensional visualization operation simulation system based on Mimics and Unigraphics NX software to provide reliable evidence for accurate preoperative surgical planning.
The preoperative CT scans of 5 patients with intertrochanteric fractures were used for three-dimensional reconstruction of intertrochanteric fractures using Mimics software. Three-dimensional reconstruction of the surgical instruments was carried out using the modeling function of Unigraphics NX software, whose assembly function was used to visualize the simulates internal fixations of intertrochanteric fractures with dynamic hip screw (DHS) system. The operative procedures simulated by Unigraphics NX were analyzed preoperatively.
The virtual surgery procedures were clearly and vividly visualized in three dimensions. The fracture reduction and surgical effects could be predicted using this system.
This system of three-dimensional visualization of virtual surgery for intertrochanteric fractures has important values in surgical planning, risk assessment and clinical training, and can help improve the reliability and outcome of orthopedic surgery.
基于Mimics和Unigraphics NX软件建立计算机辅助三维可视化手术模拟系统，为准确的术前手术规划提供可靠依据。
采用Mimics软件对5例股骨转子间骨折患者的术前CT扫描数据进行股骨转子间骨折的三维重建。利用Unigraphics NX软件的建模功能对手术器械进行三维重建，其装配功能用于可视化模拟动力髋螺钉（DHS）系统治疗股骨转子间骨折的内固定情况。术前分析Unigraphics NX模拟的手术操作过程。
虚拟手术过程在三维空间中清晰、生动地呈现。利用该系统可预测骨折复位及手术效果。
该股骨转子间骨折虚拟手术三维可视化系统在手术规划、风险评估及临床培训方面具有重要价值，有助于提高骨科手术的可靠性及手术效果。
