Blank from which a customized prosthetic part can be machined

Abstract

A blank used for machining customized prosthetic components is provided which includes a prefabricated seating surface, normally shaped as an anti-rotation device, used to seat the component in the corresponding implanted, or natural, surface in the patient's body. Prosthetic components need to be custom manufactured because each patient presents a different need, however, the standardized shape of seating surfaces allows for these to be machined in large scale, without affecting the quality of the treatment the patient receives. Once the customized manufacturing has been completed around the seating surface, the part requires no further machining and is ready to be used.

       16 . The blank of  claim 14 , wherein the at least one pre-fabricated seating surface is the bottom outer surface.  
   
   
       17 . The blank of  claim 14 , wherein the at least one pre-fabricated seating surface is one of the sides of the multi-sided outer surface.  
   
   
       18 . The blank of  claim 8 , wherein the first support portion is attached to the second component portion.  
   
   
       19 . The blank of  claim 18 , wherein the first support portion is attached to the second component portion by a chemical compound.  
   
   
       20 . The blank of  claim 19 , wherein the chemical compound is a cement.  
   
   
       21 . The blank of  claim 18 , wherein the blank body includes a top outer surface, a bottom outer surface, and a cylindrical outer surface.  
   
   
       22 . The blank of  claim 18 , wherein the blank body includes a top outer surface, a bottom outer surface, and a multi-sided outer surface.  
   
   
       23 . The blank of  claim 8 , wherein the biocompatible material is Titanium.  
   
   
       24 . The blank of  claim 8 , wherein the biocompatible material is a ceramic material.  
   
   
       25 . The blank of  claim 8 , wherein the biocompatible material is a biomaterial.  
   
   
       26 . The blank of  claim 8 , wherein the at least one anti-rotation element is hexagonal in shape.  
   
   
       27 . The blank of  claim 8 , wherein the at least anti-rotation element is a shaped as a Morse-Cone.
