Femoral sizing apparatus
First Claim
1. A femoral sizing apparatus for use by a surgeon in determining the appropriate femoral component size to be used in reconstructive surgery on the distal femur of a patient, said apparatus comprising:
- a plurality of plate means, each having a specific anterior to posterior first dimension and a medial to lateral second dimension, for placement against the distal femur, each of said plurality of plate means corresponding to a specific femoral component size, and for viewing a projection of each plate means onto the distal femur and thereby determining the appropriate femoral component size.

Abstract
A femoral sizing apparatus includes a plurality of flat templates, each having specific anterior to posterior first dimensions and medial to lateral second dimensions. Each of the plurality of plates correspond to a specific femoral component size. A handle is attached to each of the templates and is used for lifting and placing the plate against the distal femur after the distal femoral cut is made. When the template is placed against the distal femur, both the anterior to posterior dimension and the medial to lateral dimension are considered in determining the appropriate femoral component size. The template includes anchoring pin holes for receiving anchoring pins therethrough and attaching the template to the femur distal end. Drill guide holes are also provided. The template is flat and generally U-shaped for slipping over an intramedullary rod.

13. A method of sizing an appropriate femoral component using an apparatus comprising a plurality of plates, each plate having a specific anterior to posterior first dimension and a medial to lateral second dimension, and each of said plates corresponding to a specific femoral component size, said method comprising:
-
locating one of the plates that best correspondingly fits a femoral distal end by placing said plurality of plates individually against the distal femoral end and viewing the plate thereat and comparing the distal femoral end and plate first and second dimensions; and
,identifying a femoral component corresponding to said located plate for attachment to the femoral distal end. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A femoral sizing apparatus for use by a surgeon in determining the appropriate femoral component size to be used in reconstructive surgery on the distal femur of a patient, said apparatus comprising:
a plate member having an anterior to posterior first dimension and a medial to lateral second dimension, said plate member being adapted for placement against the distal femur, said first and second dimensions corresponding to a specific femoral component size, whereby the surgeon views a projection of said plate member onto the distal femur and thereby determines the appropriate femoral component size.
