Abstract
An instrument includes a sleeve extending between proximal and distal ends. The sleeve defines a passageway. The distal end defines an engagement portion including an engagement surface extending from a first end to a second end. A peg extends outwardly from the first end. An opening that is in communication with the passageway extends through the second end. A knob is coupled to the proximal end. A shaft includes a proximal end and an opposite distal end. The distal end of the shaft includes a mating portion. The mating portion extends through the opening. The proximal end of the shaft is coupled to the knob. The knob is rotatable relative to the sleeve to rotate the shaft relative to the sleeve. Methods of use are disclosed.

1-20. (canceled)
A surgical instrument comprising:
- an outer sleeve extending between opposite proximal and distal ends, the outer sleeve defining a passageway, the distal end defining an engagement portion extending from a first end to an opposite second end, the engagement portion comprising an aperture extending through the first end and an opening extending through the second end, the opening being in communication with the passageway;
- an inner sleeve positioned in the passageway and comprising opposite proximal and distal ends, the distal end of the inner sleeve comprising a female thread;
- and
- a knob coupled to the proximal end of the inner sleeve such that the knob is rotatable relative to the outer sleeve to rotate the inner sleeve relative to the outer sleeve.
A surgical instrument comprising:
- an outer sleeve extending along a longitudinal axis between opposite proximal and distal ends, the outer sleeve defining a passageway, the distal end defining an engagement portion extending from a first end to an opposite second end, the engagement portion comprising an aperture extending through the first end and an opening extending through the second end, the opening being in communication with the passageway, the opening being coaxial with the longitudinal axis, the aperture extending at an acute angle relative to the longitudinal axis;
- an inner sleeve positioned in the passageway and comprising opposite proximal and distal ends, the distal end of the inner sleeve comprising a female thread;
- and
- a knob coupled to the proximal end of the inner sleeve such that the knob is rotatable relative to the outer sleeve to rotate the inner sleeve relative to the outer sleeve.
A surgical system comprising:
- a surgical instrument comprising:
- an outer sleeve extending between opposite proximal and distal ends, the outer sleeve defining a passageway, the distal end defining an engagement portion extending from a first end to an opposite second end, the engagement portion comprising an aperture extending through the first end and an opening extending through the second end, the opening being in communication with the passageway,
- an inner sleeve positioned in the passageway and comprising opposite proximal and distal ends, the distal end of the inner sleeve comprising a female thread, and
- a knob coupled to the proximal end of the inner sleeve such that the knob is rotatable relative to the outer sleeve to rotate the inner sleeve relative to the outer sleeve;
- and
- an implant comprising a first extension configured for disposal in the aperture and a second extension configured for disposal in the opening when the first extension is disposed in the aperture.
