Abstract
A sizing guide for facilitating the sizing of prosthetic devices that are implanted. The sizing guide is designed for consistent mounting at a fixed anatomical reference point to facilitate accurate and repeatable sizing estimations for a variety of bone types and sizes.
Claims40
A sizing guide for assisting in sizing a femoral prosthetic device during an orthopedic procedure, comprising:
- a sizing block mountable proximate a distal end of a femur at a fixed position relative to a centerline of the femoral canal;
- and
- a stylus member movably mounted to the sizing block, the stylus member being adjustable relative to the anterior cortex of the femur to provide a size indication for the femoral prosthetic device.
A method for sizing a prosthetic device to be located at a distal end of the femur, comprising:
- deploying a rod member within a femoral canal of a femur such that a rod end extends from the distal end of the femur;
- mounting a sizing guide to the rod end;
- and
- performing sizing measurements based on the position of the femoral canal.
A method for sizing a prosthetic device to be located at a distal end of the femur, comprising:
- mounting a sizing guide proximate an end of a femur at a fixed position relative to the femoral canal;
- and
- utilizing the sizing guide to perform at least one of a plurality of available femoral measurements.
A sizing guide for assisting in sizing a femoral prosthetic device during an orthopedic procedure, comprising:
- a sizing block mounted at a fixed location with respect to a femoral canal of the femur, the sizing block providing an indication of a properly sized femoral prosthetic device based on the position of the sizing block relative to the femoral canal.
A system for sizing a prosthetic device to be located at a distal end of the femur, comprising:
- means for mounting a sizing guide proximate an end of a femur at a fixed position relative to the femoral canal;
- and
- means for utilizing the sizing guide to perform at least one of a plurality of available femoral measurements.
