Abstract
Disclosed herein are methods, compositions and tools for repairing an articular joint having a failed implant. The articular repair systems are customizable or highly selectable by or adaptable to individual patients and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by or adaptable to individual patients to increase the speed, accuracy and simplicity of performing total or partial arthroplasty including revision surgeries.
Claims10
A method of making a revision implant for repairing a patient's joint, the method comprising:
- obtaining image data associated with at least a portion of a failing implant existing in the patient's joint;
- deriving information about the failing implant and the patient's joint from the image data;
- obtaining existing information about the failing implant using original electronic files that have been used to make the failing implant;
- and
- making the revision implant based on the derived information about the failing implant and the patient's joint and the existing information about the failing implant.
A method of making a surgical tool, the method comprising:
- obtaining image data associated with at least a portion of a failing joint implant;
- deriving implant surface information from the image data;
- and
- providing a surgical tool that includes a contact surface, the contact surface for engaging at least a portion of the failing implant surface, the surgical tool further including at least one guide for directing movement of a surgical instrument in preparing a revision implant site,
- wherein providing the surgical tool includes:
- shaping the contact surface based on the derived implant surface information such that at least a portion of the contact surface is substantially a negative of at least a portion of the derived implant surface;
- and
- determining position, shape and/or orientation of the at least one guide from the image data, so that changes induced on the implant site by the surgical instrument ensures a desired orientation of a revision implant.
A method of performing a revision surgery for repairing a patient's joint that has a failing implant, comprising:
- providing an implant reference surgical tool that includes a contact surface, the contact surface for engaging at least a surface portion of the failing implant, wherein the contact surface includes information about the surface portion of the failing implant, and the surgical tool further includes at least one guide for directing movement of a surgical instrument in preparing a site for a revision implant;
- engaging the contact surface of the surgical tool with the surface portion of failing implant;
- and
- preparing the revision implant site using the surgical instrument as directed by the at least one guide in the surgical tool.
