Abstract
Systems and methods for percutaneously installing a vertebral stabilization system. A first anchor is positionable within a body of a patient through a first percutaneous opening and a second anchor is positionable within a body of a patient through a second percutaneous opening. A stabilization member is positionable within the body of a patient through the first percutaneous opening to engage and connect the first and second anchors.
Claims19
A system for inserting a vertebral stabilization member percutaneously, comprising:
- a bone anchor;
- a sleeve attached to the bone anchor;
- a rod member extending from a proximal end to a distal end along a rod axis, wherein the rod member has a pair of indentations coaxially aligned on a pivot axis that extends generally perpendicular to the rod axis and the rod member is pivotable about the pivot axis;
- and
- an insertion device releasably coupled to the rod member and configured to insert the rod member into position adjacent the bone anchor, wherein the insertion device extends from a proximal end to a distal end along a longitudinal axis, the insertion device comprising a first member and a second member, wherein the first member is linearly translatable with respect to the second member along the longitudinal axis, wherein the rod member is engaged to the first member at a first axial location along the rod member and rotatably engaged to the second member at a second axial location along the rod member that is axially offset from the first axial location such that, when the first member is translated with respect to the second member along the longitudinal axis the rod member rotates about the second member.
