Cutting block

Abstract

A cutting block and method for use in preparing a bone during orthopaedic surgery are disclosed. The cutting block comprises a bone attachment face, and a front face opposing the bone attachment face. The cutting block further comprises at least a first group of bone pin holes, each hole being configured for removable receipt of a bone pin. The first group of pin holes includes at least two bone pin holes that extend between the bone attachment face and the front face. The at least two bone pin holes extend parallel to each other in an anterior-posterior direction. The at least two bone pin holes are offset from each other in at least one of a superior-inferior direction or a medial-lateral direction. The at least two bone pin holes are interconnected.

1 . A method of surgically preparing a bone, the method comprising:
 inserting a bone pin into the bone,   securing a cutting block to the bone, said cutting block comprising:
 a bone attachment face, and 
 a front face opposing the bone attachment face, 
   wherein the cutting block further comprises at least a first group of bone pin holes, the first group of pin holes including at least two bone pin holes that extend between the bone attachment face and the front face,   wherein the at least two bone pin holes extend parallel to each other in an anterior-posterior direction,   wherein the at least two bone pin holes are offset from each other in at least one of a superior-inferior direction or a medial-lateral direction, and   wherein the at least two bone pin holes are interconnected, wherein the step of securing the cutting block to the bone includes:
 aligning at least one of the two bone pin holes with the bone pin, and 
 sliding the cutting block in a posterior direction along the bone pin towards the bone. 
   
     
     
         2 . A method of surgically preparing a proximal end of a tibia, the method comprising inserting a bone pin into the tibia,
 securing a tibial cutting block to the tibia, said cutting block comprising
 a bone attachment face, and 
 a front face opposing the bone attachment face, 
   wherein the cutting block further comprises at least a first group of bone pin holes, the first group of pin holes including at least two bone pin holes that extend between the bone attachment face and the front face,   wherein the at least two bone pin holes extend parallel to each other in an anterior-posterior direction,   wherein the at least two bone pin holes are offset from each other in at least one of a superior-inferior direction or a medial-lateral direction, and   wherein the at least two bone pin holes are interconnected, wherein the step of securing the cutting block to the bone includes:
 aligning at least one of the two bone pin holes with the bone pin, and 
 sliding the tibial cutting block in a posterior direction along the bone pin towards the tibia.
