Summary
This study introduces Hip-Op, a novel surgical simulation software for total hip replacement pre-operative planning. It offers a 3D planning environment with multimodal displays to enhance surgical accuracy and implant fitting.
Area of Science:
- Orthopedic Surgery
- Medical Imaging
- Surgical Simulation Software
Background:
- Pre-operative planning for total hip replacement (THR) is crucial for successful outcomes.
- Current planning methods may lack detailed anatomical visualization and implant fit assessment.
Purpose of the Study:
- To describe an innovative surgical simulation software, Hip-Op, for pre-operative planning of total hip replacement.
- To present a CT-based 3D planning environment with a user-friendly graphic interface and multimodal display.
Main Methods:
- The Hip-Op software utilizes a CT-based 3D internal representation.
- It employs a multimodal display paradigm integrating orthogonal radiographs, blended slices, CT slices, arbitrary slices, and surface rendering.
- Prosthetic components are dynamically selected and navigated within the CT volume, with simultaneous rendering of implant and anatomy.
Main Results:
- The software allows surgeons to evaluate anatomical compatibility, implant type, size, and position.
- Two analysis modules compute implant fitting and filling levels.
- The system was evaluated in an internal clinical trial.
Conclusions:
- Hip-Op provides an advanced tool for pre-operative planning in total hip replacement surgery.
- The multimodal display and analysis modules aid in optimizing implant selection and placement.
- The software is available as freeware.
