title: [Three-dimensional visualization of virtual surgery for intertrochanteric fractures].
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  The virtual surgery procedures were clearly and vividly visualized in three dimensions. The fracture reduction and surgical effects could be predicted using this system.
  
  
  CONCLUSIONS
  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.
