1. A minimally invasive vertebral stabilization system, comprising:
a first anchor deliverable to a vertebral body of a patient through a first opening with an access sleeve connected thereto, the access sleeve including a central channel extending therethrough and defining a first longitudinal axis; an elongate stabilization member extending from a proximal end to a distal end and defining a second longitudinal axis, wherein the stabilization member is positionable through the access sleeve to engage the first anchor; and a stabilization member insertion device releasably and rotatably linked to the stabilization member, the stabilization member insertion device configured and dimensioned to be received within the central channel such that the insertion device and stabilization member are moveable in the longitudinal direction along the first longitudinal axis to position the stabilization member adjacent the first anchor, wherein the stabilization member is releasably clampable to the insertion device between first and second clamping members, wherein the first clamping member includes a first generally cylindrical protrusion insertable into a distal portion of the insertion device and the second clamping member includes a second generally cylindrical protrusion insertable into the distal portion of the insertion device, wherein the first and second clamping members are coupled by a pin extending through a first and second opening in the first and second clamping members, respectively, and wherein the system further comprises a pin assembly extending through the insertion device, wherein when in a first position, a distal end of the pin assembly is spaced away from the first and second protrusions to allow the first and second clamping members to pivot apart, and when in a second position, the distal end of the pin assembly is positioned between the first and second protrusions to hold the stabilization member between the first and second clamping members. |
