Kinematic and parameterized modeling for patient-adapted implants, tools, and surgical procedures
Patient-adapted articular repair systems, including implants, instruments, and surgical plans, and methods of making and using such systems, are disclosed herein. In particular, various embodiments include methods of selecting and/or designing patient-adapted surgical repair systems using parameterized models and/or multibody simulations.
1. A method of producing a system for treatment of a joint of a patient, the system including an implant and a jig, the method comprising:
receiving preoperative patient-specific image data of the joint;
performing a first segmentation of at least a portion of the patient-specific image data to create a first model of one or more surfaces of the joint;
performing a shape search of a case database of pre-existing implant designs;
selecting the original implant design from the case database of pre-existing implant designs that is a best fit with the model;
performing a second segmentation of a select local portion of the patient-specific image data to create a refined model of at least a portion of a surface of the joint;
designing a personalized jig based, at least in part, on the refined model;
manufacturing the personalized jig;
providing an implant based on the original implant design; and
packaging the personalized jig with the implant.
2. The method of claim 1 , wherein providing includes modifying the original implant design to improve fit with the first model.
3. The method of claim 1 , wherein providing includes modifying the original implant design based, at least in part, on the refined model.
4. The method of claim 1 , wherein the implant is based on the original implant design without modification.
5. The method of claim 1 , wherein the select local portion of the patient-specific image data is a subset of the at least a portion of the patient-specific image data upon which the first segmentation was performed.
6. The method of claim 1 , further comprising:
receiving preoperative patient-specific ligament information;
performing a multibody simulation based, at least in part, on the selected original implant design and the patient-specific ligament information.
7. The method of claim 6 , wherein providing includes modifying the original implant design based on results from the multibody simulation.
8. The method of claim 6 , wherein the implant is based on the original implant design without modification.
