Abstract
An implant connector comprises a first surface defining a first cavity configured for disposal of a first implant. A second surface defines a second cavity configured for disposal of a coupling member. A third surface defines a third transverse cavity configured for disposal of a second implant. The third surface includes a projection configured to engage the second implant in a provisional locking orientation. Methods of use are disclosed.
Claims6
A spinal correction system comprising:
- a plurality of tethers including a first flexible tether;
- a spinal rod defining a central axis and including an arcuate outer surface;
- and
- a plurality of connectors including a first connector comprising a body including an outer surface and a first inner surface defining a first passageway extending through the body, the first passageway defining a first axis and being configured for disposal of the first flexible tether,
- the body further including a second threaded inner surface defining a second passageway extending through the body, the second passageway defining a second axis disposed at an angular orientation relative to the first axis and being configured for disposal of a set screw, the set screw defining a central axis and a tapered tip, and
- the body further including a third surface defining a third passageway having an oblong cross section extending through the body, the third passageway defining a third axis disposed in a transverse orientation relative to the first axis and the second axis, the third passageway being configured for disposal of the spinal rod,
- wherein the second passageway communicates with the third passageway such that the tapered tip is engageable with the arcuate outer surface to translate the spinal rod laterally along the oblong cross section of the third passageway and the first passageway communicates with the third passageway such that the spinal rod is engageable with the first flexible tether for fixation therewith.
A method for treating a spine disorder, the method comprising the steps of:
- providing a first flexible implant;
- disposing the first flexible implant with a first vertebra;
- providing a first connector comprising:
- a first surface defining a first cavity,
- a second surface defining a second cavity configured for disposal of a coupling member, and
- a third surface defining a third transverse cavity and including a projection;
- providing a second implant;
- disposing the second implant with the third cavity such that the projection engages the second implant in a provisional locking orientation;
- disposing the first flexible implant with the first cavity;
- engaging the coupling member with the second implant to overcome the provisional locking orientation of the projection such that the second implant engages the first flexible implant for fixation therewith.
