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.
Claims20
A spinal implant comprising:
- a first member extending a longitudinal axis between opposite first and second ends, an outer surface of the first member including a section having a decreasing taper from a portion of the first end to an end surface of the first end, the section comprising a plurality of steps;
- a second member including an axial cavity configured for disposal of the first member;
- a third member comprising an inner surface that engages the steps such that the third member is rotatable relative to the first member, the third member defining a transverse cavity;
- and
- a locking element disposable in the transverse cavity and engageable with the first member to fix the third member relative to the first member.

A spinal implant comprising:
- an inner body extending a longitudinal axis between opposite first and second ends, an outer surface of the first member including a section having a decreasing taper from a portion of the first end to an end surface of the first end, the section comprising a plurality of steps;
- an outer body including a wall that defines an axial cavity configured for disposal of the inner body;
- a cap comprising an inner surface that engages the steps such that the third member is pivotable relative to the inner body, the cap defining a transverse cavity, the cap being engageable with vertebral tissue;
- and
- a set screw disposable in the transverse cavity and engageable with the inner body to fix the cap relative to the inner body.

- a first member extending a longitudinal axis between opposite first and second ends, an outer surface of the first member including a section having a decreasing taper from a portion of the first end to an end surface of the first end, the section comprising a plurality of steps;
- a second member including an axial cavity configured for disposal of the first member;
- a monolithic third member comprising an inner surface that engages the steps such that the third member is rotatable relative to the first member, the third member defining a transverse cavity;
- a locking element disposable in the transverse cavity and engageable with the first member to fix the third member relative to the first member;
- and
- an inserter engageable with at least one of the members,
- wherein the third member is moveable relative to the longitudinal axis between a first orientation such that the cap is disposed at a first angle relative to the longitudinal axis and a second orientation such that the cap is disposed at a second selected angle relative to the longitudinal axis.
