Abstract
A spinal construct comprises a connector defining a longitudinal axis and extending between a first end and a second end. The connector defines a cavity and includes a member that is selectively disposable in the cavity at one of a plurality of positions between the ends. A first longitudinal element is dynamically movable within the cavity and engageable with the member to limit movement in a first axial direction. The first longitudinal element is connectable with vertebral tissue. A second longitudinal element is disposable within the cavity and connectable with vertebral tissue. Systems and methods are disclosed.
Claims19
A spinal construct comprising:
- a connector defining a longitudinal axis and extending between a first end and a second end, the connector comprising an opening extending through opposite uppermost and bottommost surfaces of the connector, the connector defining a cavity and including a member being selectively disposable in the opening such that a distal end of the member is positioned in the cavity;
- a first longitudinal element being dynamically movable within the cavity and engageable with the member to limit movement in a first axial direction, the first longitudinal element being connectable with vertebral tissue;
- and
- a second longitudinal element disposable within the cavity and connectable with vertebral tissue, the second longitudinal element being spaced apart from the first longitudinal element along the longitudinal axis,
- wherein the first longitudinal element includes a first end fixed with at least one vertebra and a second end dynamically movable within the cavity.
A spinal construct comprising:
- a connector defining a longitudinal axis and an axial passageway, the connector further defining at least five spaced apart threaded transverse openings that are each in communication with the passageway;
- a member selectively disposable within one of the openings and in alignment with the cavity;
- a first rod fixed with the connector and connectable with at least one vertebra;
- and
- a second rod being dynamically movable within the cavity and engageable with an end of the first rod or the member to limit movement in a first axial direction, the second rod being connectable with at least one vertebra.
A spinal construct comprising:
- a connector defining a longitudinal axis and extending between a first end comprising a first threaded opening and a second end comprising a second threaded opening, the connector comprising a third threaded opening between the first and second openings, the connector defining a cavity and including a member being selectively disposable in one of the openings such that a distal end of the member is positioned in the cavity;
- a first longitudinal element being dynamically movable within the cavity and engageable with the member to limit movement in a first axial direction, the first longitudinal element being connectable with vertebral tissue;
- a second longitudinal element disposable within the cavity and connectable with vertebral tissue;
- and
- a second member disposable in another one of the openings such that a distal end of the second member is positioned in the cavity and engages the second longitudinal element such that the second longitudinal element is movable in the first axial direction and is prevented from moving in an opposite second axial direction,
- wherein the member has a maximum length that is less than that of the second member.
