Abstract
An interspinous implant comprises a first member and a second member. The members define a pathway. A third member is movable along the pathway relative to the first member and the second member. Systems and methods are disclosed.
Claims20
An interspinous implant comprising:
- a first member extending along a longitudinal axis between opposite first and second ends, the first member comprising an inner surface defining a slot extending from the first end to the second end;
- a second member extending between opposite first and second ends, the second member comprising an inner surface defining a slot extending from the first end of the second member to the second end of the second member, at least one of the members comprising an opening that extends transverse to the longitudinal axis;
- and
- a third member positioned within the slots and movable relative to the first member and the second member along the longitudinal axis,
- wherein a top surface of the third member and the inner surfaces define a first cavity configured for disposal of a first spinous process and a bottom surface of the third member and the inner surfaces define a second cavity configured for disposal of a second spinous process.

An interspinous implant comprising:
- a first member extending between opposite first and second ends, the first member defining an opening and including an inner surface defining a slot that extends from the first end to the second end;
- a second member extending between opposite first and second ends, the second member defining an opening and including an inner surface defining a slot that extends from the first end of the second member to the second end of the second member, the slots defining an arcuate track and the members including a vertebral engaging surface that defines a tissue mating curvature;
- and
- an intermediate member movable along the track relative to the first member and the second member,
- wherein a top surface of the intermediate member and the inner surfaces define a first cavity configured for disposal of a first spinous process and a bottom surface of the intermediate member and the inner surfaces define a second cavity configured for disposal of a second spinous process.

A plate comprising:
- a first member extending between opposite first and second ends, the first member including an inner surface that defines a slot that extends from the first end to the second end;
- a second member extending between opposite first and second ends, the second member including an inner surface that defines a slot that extends from the first end of the second member to the second end of the second member;
- and
- an intermediate member extending between opposite first and second ends, the intermediate member comprising side surfaces that are each movably disposed within one of the slots,
- a top surface of the intermediate member and the inner surfaces defining a first cavity configured for disposal of a first spinous process and a bottom surface of the intermediate member and the inner surfaces defining a second cavity configured for disposal of a second spinous process,
- the plate including a vertebral engaging surface that defines a tissue mating curvature.
