Summary
This study developed a computer program to simulate total hip replacement surgery, optimizing implant placement for better range of motion (ROM). The simulation accurately predicts ROM based on component angles, aiding surgical planning.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Computer Simulation
Background:
- Total hip arthroplasty (THA) requires precise component placement for optimal patient outcomes.
- Estimating the range of motion (ROM) preoperatively is crucial for successful THA.
- Current methods for ROM prediction may lack precision and dynamic simulation capabilities.
Purpose of the Study:
- To develop and present a computer program for preoperative simulation of implant component placement in THA.
- To evaluate the program's influence on the possible range of motion (ROM).
- To establish a virtual computer simulation for movement mapping in total hip replacement.
Main Methods:
- Development of a computer program using Borland C++ for THA simulation.
- Implementation of an open data port for transferring data to Excel for statistical analysis.
- Creation of a practical model based on virtual computer simulation to analyze ROM patterns.
Main Results:
- The simulation demonstrated ROM patterns consistent with clinical experience.
- Optimal ROM was achieved with specific component angles: shaft anteversion (20-30 degrees), CCD angle (120-130 degrees), acetabular cup anteversion (10-20 degrees), and cup inclination (<40 degrees).
- The system provides a reliable method for dynamic preoperative planning.
Conclusions:
- The developed movement mapping system offers a reliable approach for dynamic preoperative planning in THA.
- Accurate simulation of component placement can optimize ROM and potentially improve surgical outcomes.
- This system may serve as a prerequisite for utilizing intraoperative navigation systems in THA.
