Abstract
An anchor for a pedicle screw having an anchor body comprising a proximal end, a proximal portion, a distal portion, and a distal end, and a through-hole through the anchor body from the proximal end to the distal end. The through-hole defines a long axis of the anchor, and is provided with undersized female threads in the proximal portion and a reduced inner diameter in the distal portion. The reduced inner diameter causes expansion of at least the distal portion of the anchor body when a screw is inserted into the through-hole. The anchor is further provided with a plurality of ridges on an exterior surface of the anchor body, the ridges configured to reduce the likelihood of pullout when the anchor is inserted into a vertebra and a screw is inserted into the through-hole.
