Abstract
A surgical instrument comprises a first member including a drive engageable with a first mating surface of a bone fastener. A second member is rotatable relative to the first member and includes an element engageable with a second mating surface of the bone fastener. An actuator is connected with the second member and includes visual indicia of engagement of the element with the second mating surface. Systems, spinal implants and methods are disclosed.

A surgical instrument comprising:
- a first member including a drive engageable with a first mating surface of a bone fastener;
- and
- a second member including a screw engageable with a second mating surface of the bone fastener, the screw being fixed to a distal end of the second member by a pin, the screw having an outer thread surface connectable with the second mating surface, the first member defining an inner cavity, the second member being rotatably disposed within the inner cavity.
A surgical system comprising:
- a bone fastener including a screw and a receiver, the screw being rotatable relative to the receiver, the screw comprising a first mating surface, the receiver comprising a second mating surface;
- and
- a surgical instrument comprising a first member including a drive, the drive being engageable with the first mating surface, the surgical instrument comprising a second member, the second member including a screw engageable with the second mating surface, the screw being fixed to a distal end of the second member by a pin, the screw having an outer thread surface connectable with the second mating surface, the first member defining an inner cavity, the second member being rotatably disposed within the inner cavity.
A surgical system comprising:
- a bone fastener including a screw and a receiver, the screw being rotatable relative to the receiver, the screw comprising a socket, the receiver comprising a female thread form;
- and
- a surgical instrument comprising a first member including a drive, the drive being configured for disposal in the socket, the surgical instrument comprising a second member, the second member including a screw, the screw being fixed to a distal end of the second member by a pin, the screw comprising a male thread form engageable with the female thread form, the first member defining an inner cavity, the second member being rotatably disposed within the inner cavity.
