Revision total ankle implants

Abstract

In some embodiments, a revision implant includes a body extending between a first planar surface and a second planar surface and a head extending from the first planar surface of the body. The head is configured to couple the revision implant to at least one additional component of a multi-component prosthesis. At least one coupling mechanism is configured to couple the body to a first bone.

What is claimed is: 
     
         1 . A surgical method, comprising:
 creating an incision in a patient;   exposing a multi-component prosthesis implanted in a patient;   disassembling at least one component of the multi-component prosthesis; and   coupling a revision implant component to a first component of the multi-component prosthesis,   wherein the revision implant component comprises a body extending between a first planar surface and a second planar surface, a head extending from the first planar surface of the body and configured to couple the revision implant to at least one additional component of a multi-component prosthesis, and at least one coupling mechanism configured to couple the body to a bone.   
     
     
         2 . The surgical method of  claim 1 , further comprising coupling the revision implant component to an augment sized and configured to fill a void in a first bone. 
     
     
         3 . The surgical method of  claim 1 , further comprising forming one or more holes in a bone, wherein each of the one or more holes are configured to receive a protrusions extending from a bottom surface of the revision implant component. 
     
     
         4 . The surgical method of  claim 3 , further comprising:
 selecting an angle of insertion for a variable angle peg into a hole formed through the body of the revision implant component; and   inserting the variable angle peg through the body at the selected angle and into one of the at least one holes.   
     
     
         5 . A revision implant kit, comprising:
 a first revision implant comprising:   a body extending between a first planar surface and a second planar surface;   a head extending from the first planar surface of the body and configured to couple the revision implant to at least one additional component of a multi-component prosthesis; and   at least one coupling mechanism configured to couple the body to a first bone;   a second revision implant comprising an augment configured to fill a void formed in the first bone, the second revision implant configured to couple to the second planar surface of the body of the first revision implant; and   a third revision implant comprising a body defining an articulation surface, wherein the third revision implant is configured to be coupled to a first planar surface of the first revision implant.   
     
     
         6 . The revision kit of  claim 5 , wherein the first revision implant comprises a talar plate revision, the second revision implant comprises a talar augment, and the third revision implant comprises a talar dome.
