  • Patent number: 11116559
    Abstract: A surgical instrument includes a first member that includes a first element engageable with an inner surface of a head of a bone fastener and a second element engageable with an outer surface of the head. The first member defines a first-member longitudinal axis and the bone fastener defines a bone-fastener longitudinal axis. A second member defines a second-member longitudinal axis and is movable relative to the first member and engageable with the second element to dispose the first element and the second element with the head in a co-axial, capture orientation. wherein the first-member, bone-fastener, and second-member longitudinal axes are aligned. Systems, spinal constructs, implants and methods are disclosed.
