Patient matched instrument

Abstract

A patient matched instrument is disclosed. The patient matched instrument includes a body having an interior patient matched surface; a cutting slot extending through at least a portion of the body; a first paddle extending from the body; and a second paddle spaced apart from the first paddle and extending from the body; and wherein at least one of the first paddle and the second paddle further comprises a hook.

What is claimed is: 
     
         1 . A patient matched instrument comprising:
 a. a body having an interior patient matched surface;   b. a cutting slot extending through at least a portion of the body;   c. a first paddle extending from the body; and   d. a second paddle spaced apart from the first paddle and extending from the body; and wherein at least one of the first paddle and the second paddle further comprises a hook.   
     
     
         2 . The patient matched instrument of  claim 1 , wherein the body includes at least one fixation hole. 
     
     
         3 . The patient matched instrument of  claim 1 , wherein one of the first paddle and the second paddle is thinner or thicker than the other paddle. 
     
     
         4 . The patient matched instrument of  claim 1 , wherein the interior patient matched surface has a surface roughness different than the remainder of the body. 
     
     
         5 . The patient matched instrument of  claim 1 , wherein the cutting slot comprises a ledge. 
     
     
         6 . The patient matched instrument of  claim 1 , further comprising an area of the body configured to contact a portion of an anterior of a particular patient's tibia and is matched to the particular patient's anatomy. 
     
     
         7 . The patient matched instrument of  claim 1 , further comprising a first member and a second member, and wherein the first member and the second member intersect to provide a confidence point. 
     
     
         8 . The patient matched instrument of  claim 1 , further comprising a built-in alignment checker. 
     
     
         9 . The patient matched instrument of  claim 8 , wherein the built-in alignment checker has a receiver and a bridge. 
     
     
         10 . The patient matched instrument of  claim 1 , wherein each paddle has a contact surface. 
     
     
         11 . The patient matched instrument of  claim 10 , wherein the interior patient matched surface and the contact surfaces are used to locate the cutting slot.
