Kinematic and Parameterized Modeling for Patient-Adapted Implants, Tools, and Surgical Procedures

Abstract

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.

What is claimed is: 
     
         1 . A method of making an implant and/or jig for a patient, the method comprising:
 receiving patient-specific image data;   segmenting at least a portion of the patient-specific image data;   performing a shape search of a case database of original implant designs and/or jig designs; and   if an original implant design is found by the shape search that is a good match, selecting the original implant design and/or a corresponding original jig design for making the implant and/or jig for the patient.   
     
     
         2 . The method of making an implant and/or jig of  claim 1 , further comprising: if no original implant design that is a good match is found by the shape search, designing a new implant design and/or a new jig design based, at least in part, on the patient-specific image data. 
     
     
         3 . The method of making an implant and/or jig of  claim 1 , further comprising:
 if no implant design that is a good match is found by the shape search, deriving a statistical model match;   adapting one or more shape parameters of a parameterized model based on the derived statistical model match;   evaluating the adapted shape parameter model a first time in a multibody simulation;   if the results of the first multibody simulation are good, generating an implant design and/or jig design for making the implant and/or jig for the patient from the adapted shape parameter model;   if the results of the of the first multibody simulation are not good, subsequently adapting one or more shape parameters and evaluating the subsequently adapted shape parameter model in a subsequent multibody simulation;   if the results of the subsequent multibody simulation are good, generating an implant design and/or jig design for making the implant and/or jig for the patient from the subsequently adapted shape parameter model; and   if the results of the of the subsequent multibody simulation are not good, repeating the steps above of subsequently adapting and evaluating the subsequently adapted shape parameter model until the results of the subsequent multibody simulation are good.   
     
     
         4 . A method of making a patient-specific implant according to a process as shown in  FIG. 31 . 
     
     
         5 . A method of generating an optimized implant model according to a process as shown in  FIG. 32 . 
     
     
         6 . A method of performing a finite element analysis on an implant model according to a process as shown in  FIG. 33 . 
     
     
         7 . A method of selecting and/or designing an implant design and/or a jig design for a patient according to a process as shown in  FIG. 35 . 
     
     
         8 . A method of making a patient-specific implant according to a process as shown in  FIG. 36 . 
     
     
         9 . An implant produced according to the method of  claim 1 ,  2 ,  3 ,  4 ,  5 ,  7 , or  8 . 
     
     
         10 . A system for treating a patient comprising an implant produced according to the method of  claim 1 ,  2 ,  3 ,  4 ,  5 ,  7 , or  8  and a jig produced according to the method of  claim 1 ,  2 ,  3 , or  7 .
