Personalized Hip Implant Design via Virtual Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for hip dysplasia, such as the shelf procedure and pelvic osteotomy, are invasive and lack precision, leading to potential impingements and reduced freedom of movement due to imperfect acetabular coverage and bone modifications.
Innovation Solution
A method for manufacturing personalized bone implants using data sets of patient bones, creating models, simulating movements, and modifying the implant design to avoid impingements, ensuring precise fit and minimizing bone modifications, with the option of three-dimensional printing using biofunctional materials like titanium and magnesium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical treatments like shelf procedure or pelvic osteotomy are used to treat hip dysplasia, then acetabular coverage can be improved, but the invasiveness of the procedure increases and precision decreases
Solution Approach 1:
The implant design is performed in advance using virtual planning and movement simulation before the actual surgery. The implant is customized based on pre-operative imaging data (CT or MRI) and simulated to ensure it will not impinge on bone movements. This preliminary digital planning and customization allows for precise, minimally invasive surgery by eliminating the need for extensive intraoperative bone modifications.
2Reliability
If traditional surgical treatments are used to increase acetabular coverage, then coverage is improved, but impingement of joint movement may occur
Solution Approach 1:
Movement simulation is performed using the patient's specific anatomical data and defined range of motion parameters. The simulation provides feedback on whether the proposed implant design would cause impingement or restrict joint movement. Based on this feedback, the implant design is optimized to achieve adequate acetabular coverage while maintaining full freedom of movement, eliminating the need for trial-and-error surgical adjustments.
3Ease of manufacture
If precise implant fitting is achieved through traditional methods, then bone modification is minimized, but precision is limited
Solution Approach 1:
The implant design parameters are customized based on the patient's specific anatomical measurements derived from imaging data. The implant geometry, size, and position are optimized using virtual planning software to achieve precise fit with the patient's unique bone structure. This parameter customization allows for high-precision implant placement that conforms exactly to the patient's anatomy, minimizing bone modification while achieving optimal fit.
