METHOD FOR SELECTING MODULAR IMPLANT COMPONENTS
First Claim
1. A method for selecting an orthopedic implant from a system of orthopedic implants for implantation in an anatomical structure of a patient, the method comprising the steps of:
- acquiring an image of the anatomical structure;
using a template with a grid coordinate system to assess at least one of a first, second, and third variable associated with respective physical characteristics of the implants, the grid coordinate system having a plurality of reference points corresponding to at least two of the first, second, and third variables; and
selecting a first orthopedic implant from the system of implants based on coordinates determined using the template.

Abstract
A method for selecting modular neck components for hip implants based on independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The present method allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables. The method may include preoperative planning in which a template including a grid coordinate system is used.

10. A method for intraoperatively selecting an orthopedic implant for implantation in an anatomical structure of a patient, the method comprising the steps of:
-
assessing, intraoperatively, at least one of a first, a second, and a third variable associated with respective physical characteristics of the implant; and selecting an orthopedic implant based on a change in the at least one variable from a system in which the implants are arranged in subsets in which one of the others of the first, second, and third variables is constant. - View Dependent Claims (11, 12, 13, 14, 15, 16)
