摘要:
A system for generating a PSI jig model for implant revision comprises a reference anchor surface identifying module to identify at least one reference anchor surface from at least one patient specific image of a bone and of an implanted implant, the reference anchor surface configured to receive a guide reference(s). An implant abutment surface determining module determines an implant abutment surface from the patient specific bone image. A PSI reference jig model generator module generates and outputs a reference jig model using the identified reference anchor surface and the determined implant abutment surface, the reference jig model comprising contact surface(s) corresponding to the determined implant abutment surface for complementary connection with the determined implant abutment surface, guide interfacing portion(s) configured to guide a planting of the guide reference in the reference anchor surface, and a patient-specific geometry between contact surface(s) and the guide interfacing portion, so as to position and/or orient the guide interfacing portion relative to the reference anchor surface, for subsequently planting the guide reference(s) in the reference anchor surface as identified when the contact surface(s) is complementarily connected with the determined implant abutment surface. A method for creating patient-specific instrumentation jig for implant revision is also provided.
