Spinal implant system and method

Abstract

A spinal construct includes a coupling member including a first mating surface engageable with an existing fastener implant. The existing fastener implant defines a cavity configured for disposal of an existing spinal rod implant. A connector is engageable with the existing fastener implant and has a rod extending therefrom. A locking member is engageable with a second mating surface of the coupling member. Systems, surgical instruments, implants and methods are disclosed.

What is claimed is: 
     
         1 . A spinal construct comprising:
 a coupling member including a first mating surface engageable with an existing fastener implant, the existing fastener implant defining a cavity configured for disposal of an existing spinal rod implant;   a connector engageable with the existing fastener implant and capable of having a rod extending therefrom; and   a locking member engageable with a second mating surface of the coupling member.   
     
     
         2 . A spinal construct as recited in  claim 1 , wherein the first mating surface includes a first thread and the second mating surface includes a second thread. 
     
     
         3 . A spinal construct as recited in  claim 1 , wherein the coupling member includes a flange disposed between the first mating surface having a first thread and the second mating surface having a second thread. 
     
     
         4 . A spinal construct as recited in  claim 1 , wherein the coupling member includes a break off portion. 
     
     
         5 . A spinal construct as recited in  claim 1 , wherein the coupling member includes a first set screw having the first mating surface and a second set screw having the second mating surface. 
     
     
         6 . A spinal construct as recited in  claim 5 , wherein the first mating surface includes a first thread and the second mating surface includes a second thread. 
     
     
         7 . A spinal construct as recited in  claim 5 , wherein the first set screw defines a cavity configured for disposal of a stem of the second set screw. 
     
     
         8 . A spinal construct as recited in  claim 1 , wherein the connector includes a receiver that defines a cavity for disposal of the rod. 
     
     
         9 . A spinal construct as recited in  claim 8 , wherein the receiver is rotatable relative to the connector. 
     
     
         10 . A spinal construct as recited in  claim 8 , wherein the receiver is rotatable relative to the connector and includes a spline surface engageable with a spline surface of the connector to fix the rod in a selected orientation. 
     
     
         11 . A spinal construct as recited in  claim 1 , wherein the connector includes a receiver that defines a cavity for disposal of the rod and is rotatable to selectively dispose the rod in a coronal plane. 
     
     
         12 . A spinal construct as recited in  claim 1 , wherein the connector includes a receiver that defines a cavity for disposal of the rod and is rotatable to selectively dispose the rod in a sagittal plane. 
     
     
         13 . A spinal construct as recited in  claim 1 , wherein the connector includes an inner surface that defines a cavity for disposal of a receiver of the existing fastener implant. 
     
     
         14 . A spinal construct as recited in  claim 1 , wherein the connector is rotatable to dispose the rod at a selected angular orientation relative to the existing spinal rod implant. 
     
     
         15 . A spinal construct as recited in  claim 1 , wherein the connector includes at least one hook configured to capture the existing spinal rod implant. 
     
     
         16 . A spinal construct as recited in  claim 1 , wherein the locking member includes a nut engageable with the connector. 
     
     
         17 . A spinal construct as recited in  claim 1 , wherein the locking member includes a break off portion. 
     
     
         18 . A spinal construct as recited in  claim 1 , wherein the locking member comprises a threaded surface of the connector. 
     
     
         19 . A spinal construct comprising:
 a setscrew including a first thread and a second, different thread, the first thread being engageable with a receiver of an existing MAS implant, the implant receiver being configured for disposal of an existing spinal rod implant;   a connector including an inner surface that defines a cavity configured for disposal of the implant receiver and a rod receiver; and   a locking member engageable with the second thread.   
     
     
         20 . A spinal construct comprising:
 a coupling member including a first mating surface engageable with an existing fastener implant, the existing fastener implant defining a cavity configured for disposal of an existing spinal rod implant;   a connector engageable with the existing fastener implant and including a receiver that defines a cavity for disposal of a rod, the receiver being rotatable relative to the connector to selectively dispose the rod relative to the existing spinal rod implant; and   a locking member engageable with a second mating surface of the coupling member.
