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.

Surgical instrument and method

A surgical instrument for implanting a bone fastener is provided. The surgical instrument comprises an elongated body having a frangible region and a distal end adjacent to the frangible region. The distal end of the surgical instrument is configured to engage the bone fastener. The bone fastener is less frangible than the frangible region of the elongated body of the surgical instrument. Kits and methods are also disclosed.

Surgical instruments and methods

A surgical system includes a bone fastener having a head and a shaft. The head has a drive interface surface including elliptical edges. A surgical instrument includes an inner drive and an outer sleeve that is engageable with an outer surface of the head to dispose the inner drive and the outer sleeve with the head in a co-axial, capture orientation. The inner drive has a drive interface surface including a plurality of spaced apart lobes. Each lobe has an elliptical edge engageable with one of the elliptical edges of the drive interface surface of the head. Spinal constructs, implants and methods are disclosed.
