Femoral cutting block

Abstract

A method of resecting a distal femur is disclosed. The method includes attaching a first block to the distal femur, the first block having a first surface providing a guiding surface for making an anterior chamfer cut on the femur, and a second surface providing a guiding surface for making a posterior chamfer cut on the femur, and making anterior and posterior chamfer cuts on the distal femur. The method further includes attaching a second block to the first block, the second block having a first surface providing a guiding surface for making an anterior cut on the femur, and a second surface providing a guiding surface for making a posterior cut on the femur, and making anterior and posterior cuts on the distal femur.

1 . A method of resecting a distal femur, the method comprising:
 attaching a first block to the distal femur, the first block having a first surface providing a guiding surface for making an anterior chamfer cut on the femur, and a second surface providing a guiding surface for making a posterior chamfer cut on the femur;   making anterior and posterior chamfer cuts on the distal femur;   attaching a second block to the first block, the second block having a first surface providing a guiding surface for making an anterior cut on the femur, and a second surface providing a guiding surface for making a posterior cut on the femur; and   making anterior and posterior cuts on the distal femur.   
     
     
         2 . The method of  claim 1 , further comprising checking accuracy of the anterior chamfer cut before the making of the anterior or posterior cuts. 
     
     
         3 . The method of  claim 2 , wherein the checking of the accuracy of the anterior chamfer cut includes checking for a gap or space between a contact surface on the second block and the resected bone surface, wherein the contact surface of the second block is parallel to the first surface of the first block. 
     
     
         4 . The method of  claim 1 , further comprising checking accuracy of the posterior chamfer cut before the making of the anterior or posterior cuts. 
     
     
         5 . The method of  claim 4 , wherein the checking of the accuracy of the posterior chamfer cut includes checking for a gap or space between a contact surface on the second block and the resected bone surface, wherein the contact surface of the second block is parallel to the second surface of the first block. 
     
     
         6 . A method of resecting a distal femur, the method comprising:
 attaching a first block to the distal femur, the first block having a first surface providing a guiding surface for making an anterior chamfer cut on the femur, and a second surface providing a guiding surface for making a posterior chamfer cut on the femur;   attaching a second block to the first block, the second block having a first surface providing a guiding surface for making an anterior cut on the femur, and a second surface providing a guiding surface for making a posterior cut on the femur;   making anterior and posterior cuts on the distal femur using the second block;   detaching the second block from the first block; and   making anterior and posterior chamfer cuts on the distal femur using the first block.   
     
     
         7 . The method of  claim 6 , further comprising detaching the first block from the distal femur. 
     
     
         8 . The method of  claim 6 , further comprising inserting one or more pins through the first block and into the distal femur to secure the first block to the distal femur. 
     
     
         9 . A method of resecting a distal femur, the method comprising:
 attaching a cutting block assembly to the distal femur, wherein the cutting block assembly comprises a first block detachably coupled to a second block, the first block having a first surface providing a guiding surface for making an anterior chamfer cut on the femur, and a second surface providing a guiding surface for making a posterior chamfer cut on the femur, and the second block having a first surface providing a guiding surface for making an anterior cut on the femur, and a second surface providing a guiding surface for making a posterior cut on the femur;   making anterior and posterior cuts on the distal femur using the second block;   detaching the second block from the first block; and   making anterior and posterior chamfer cuts on the distal femur using the first block.   
     
     
         10 . The method of  claim 9 , further comprising detaching the first block from the distal femur. 
     
     
         11 . The method of  claim 9 , further comprising inserting one or more pins through the first block and into the distal femur to secure the first block to the distal femur.
