Patient Selectable Joint Arthroplasty Devices and Surgical Tools Incorporating Anatomical Relief

Abstract

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

What is claimed is: 
     
         1 . A system for joint arthroplasty, the system comprising:
 a first template, the first template including: at least one surface for engaging a first surface of a joint, the at least one surface being substantially a negative of portions or all of the first surface; at least a portion of the at least one surface further including an anatomical relief, wherein the anatomical relief is configured based on an offset surface derived from electronic image data of the first surface of the joint; and   at least one guide for directing movement of a surgical instrument.   
     
     
         2 . The system of  claim 1 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a pre-set offset value. 
     
     
         3 . The system of  claim 2 , wherein the electronic image data of the first surface of the joint includes electronic image data of a bone surface and the pre-set offset value is based on an expected cartilage thickness for the joint. 
     
     
         4 . The system of  claim 1 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a patient-specific offset value. 
     
     
         5 . The system of  claim 1 , wherein the patient-specific offset value is based on patient-specific parameters including gender, weight, and/or height. 
     
     
         6 . A system for joint arthroplasty, the system comprising:
 a first template, the first template including: at least one surface for engaging a first surface of a joint, the at least one surface substantially conforming to portions or all of the first surface; at least a portion of the at least one surface further including an anatomical relief, wherein the anatomical relief is configured based on an offset surface derived from electronic image data of the first surface of the joint; and
 at least one guide for directing movement of a surgical instrument. 
   
     
     
         7 . The system of  claim 6 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a pre-set offset value. 
     
     
         8 . The system of  claim 7 , wherein the electronic image data of the first surface of the joint includes electronic image data of a bone surface and the pre-set offset value is based on an expected cartilage thickness for the joint. 
     
     
         9 . The system of  claim 6 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a patient-specific offset value. 
     
     
         10 . The system of  claim 6 , wherein the patient-specific offset value is based on patient-specific parameters including gender, weight, and/or height. 
     
     
         11 . A system for joint arthroplasty, the system comprising:
 a first template, the first template including: at least one surface for engaging a first surface of a joint, the at least one surface is shaped using shape information derived from electronic image data of portions or all of the first surface; at least a portion of the at least one surface further including an anatomical relief, wherein the anatomical relief is configured based on an offset surface derived from the electronic image data of the first surface of the joint; and   at least one guide for directing movement of a surgical instrument.   
     
     
         12 . The system of  claim 11 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a pre-set offset value. 
     
     
         13 . The system of  claim 12 , wherein the electronic image data of the first surface of the joint includes electronic image data of a bone surface and the pre-set offset value is based on an expected cartilage thickness for the joint. 
     
     
         14 . The system of  claim 11 , wherein the offset surface is configured based on the electronic image data of the first surface of the joint using a patient-specific offset value. 
     
     
         15 . The system of  claim 11 , wherein the patient-specific offset value is based on patient-specific parameters including gender, weight, and/or height.
