A spinal implant provides support for desired parts of the spine. The spinal implant includes a pair of elongated members and a variable length cross-link. A variable length cross-link device may include a fixed portion having a receiver portion for attachment to a first elongated member, a transverse portion ,and an adjustable portion having a receiver portion for attachment to a second elongated member and a transverse portion engaging member. Inserting the transverse portion of the fixed portion into the engaging portion of the adjustable portion may form a cross-link for stabilizing motion between two elongated members. Engaging the adjustable portion at a selected point on the transverse portion establishes a length selected by the surgeon. The surgical procedure may use minimally invasive surgery or non-minimally invasive surgery, as desired. Components may be inserted through sleeves attached to various coupling devices, or may be inserted and guided along wires. |
