Intramedullary implant systems and methods

Abstract

This disclosure describes exemplary intramedullary implant systems. The intramedullary implant systems may be used for performing bone fracture, bone fusion, or osteotomy procedures within joints.

1 . An intramedullary implant system, comprising:
 an implant including a plate portion and an integral intramedullary portion;   a locking screw received through an opening of the plate portion; and   a crossing screw received through an additional opening of the plate portion or the integral intramedullary portion,   wherein the crossing screw extends at a non-perpendicular angle relative to a centerline axis of the implant.   
     
     
         2 . The system as recited in  claim 1 , comprising talons provided on the integral intramedullary portion and configured to deploy from a first position to a second position to increase stability of the implant relative to a bone. 
     
     
         3 . The system as recited in  claim 2 , wherein the talons are provided on a proximal portion of the integral intramedullary portion. 
     
     
         4 . The system as recited in  claim 2  or  3 , wherein the talons include deployable wings, barbs, claws, or any combinations thereof. 
     
     
         5 . The system as recited in  claim 1 , wherein the plate portion is laterally offset from the integral intramedullary portion. 
     
     
         6 . The system as recited in  claim 1 , wherein the centerline axis is non-linear. 
     
     
         7 . The system as recited in  claim 6 , wherein portions of the plate portion, the integral intramedullary portion, or both are curved. 
     
     
         8 . The system as recited in  claim 1 , wherein the integral intramedullary portion is configured in the shape of a nail body, and the additional opening is formed through the nail body for receiving the crossing screw.

         14 . (canceled) 
     
     
         15 . (canceled) 
     
     
         16 . The system as recited in  claim 1 , wherein the plate portion and the integral intramedullary portion establish a single-piece structure of the implant. 
     
     
         17 . The system as recited in  claim 16 , wherein the single-piece structure excludes any mechanical attachments for connecting the plate portion and the integral intramedullary portion together. 
     
     
         18 . The system as recited in  claim 1 , wherein at least a portion of the plate portion is curved. 
     
     
         19 . The system as recited in  claim 1 , wherein at least a portion of the integral intramedullary portion is curved. 
     
     
         20 . The system as recited in  claim 1 , wherein at least a portion of both the plate portion and the integral intramedullary portion is curved. 
     
     
         21 . The system as recited in  claim 1 , wherein the plate portion establishes an extramedullary component of the implant. 
     
     
         22 . The system as recited in  claim 1 , wherein the locking screw is received through the opening of the plate portion, the crossing screw is received through the additional opening of the plate portion, and comprising a second locking screw received through a second additional opening of the plate portion. 
     
     
         23 . The system as recited in  claim 1 , wherein the additional opening that receives the cross screw is a proximal-most opening of the plate portion. 
     
     
         24 . An intramedullary implant system, comprising:
 an implant comprising:
 a plate portion; 
 an intramedullary portion; and 
 a plurality of deployable talons provided on the intramedullary portion, 
 wherein the plurality of deployable talons are movable between a retracted position and an expanded position, 
 wherein the plurality of deployable talons include barbs, claws, or a combination of barbs and claws.
