Abstract
A spinal implant has a first member defining a longitudinal axis. A second member includes an axial cavity configured for disposal of the first member. A third member is rotatable relative to the first member and defines a transverse cavity. A locking element is disposable in the transverse cavity and engageable with the first member to fix the third member relative to the first member. Systems and methods of use are disclosed.

1-20. (canceled)
A spinal implant comprising:
- a first member extending along a longitudinal axis between opposite first and second ends, the first member comprising teeth, steps and an engagement surface;
- a second member including a first cavity configured for disposal of the first member and a second cavity;
- a band rotatably positioned within the second cavity, the band comprising an outer surface that engages the first member and an opposite inner surface that engages the teeth such that rotation of the band relative to the first member moves the first member relative to the second member along the longitudinal axis;
- a third member comprising an inner surface that engages the steps, the third member defining a third cavity;
- and
- a locking element disposable in the third cavity and movable between a first orientation in which the locking element engages the engagement surface and the third member is fixed relative to the first member and a second orientation in which the locking element is spaced apart from the engagement surface and the third member is movable relative to the first member.

A spinal implant comprising:
- a first member including a first cavity;
- a second member disposed in the first cavity and extending along a longitudinal axis between opposite first and second ends, the second member comprising steps and a spherical surface, the spherical surface being recessed inwardly from an outer surface of the second member, the spherical surface being free of threads;
- a third member comprising an inner surface that engages the steps, the third member defining a second cavity;
- and
- a locking element disposable in the second cavity and movable between a first orientation in which the locking element engages the spherical surface and the third member is fixed relative to the second member and a second orientation in which the locking element is spaced apart from the spherical surface and the third member is movable relative to the second member.

A spinal implant comprising:
- an outer body including a first cavity;
- an inner body disposed in the first cavity and extending along a longitudinal axis between opposite first and second ends, the inner body comprising steps and a spherical surface, the spherical surface being recessed inwardly from an outer surface of the inner body, the spherical surface being free of threads;
- a cap comprising an inner surface that engages the steps, the cap defining a second cavity;
- and
- a setscrew disposable in the second cavity and movable between a first orientation in which the setscrew directly engages the spherical surface and the cap is fixed relative to the inner body and a second orientation in which the setscrew is spaced apart from the spherical surface and the cap is movable relative to the inner body.
