Abstract: A revisable orthopedic anchor and method of use for removably securing an anchor in bone, such as compromised or degenerated bone, is described herein. In one embodiment, the anchor makes use of dual probes and vector divergence of the distal tips of the probes to achieve superior bone purchase and pull-out resistance. In such an embodiment, the probes can be inserted one at a time into a hole formed in, for example, the pedicle bone. After the probes are inserted and joined at the proximal end, they have a greater pull-out resistance than a threaded anchor. Removing the anchor involves separating the proximal heads and reversing the implantation process. As a result of the unique bone anchor design disclosed herein, the devices and methods of the present invention allow for less complicated implantation and removal of orthopedic anchors, all while providing enhanced bone purchase when implanted in a patient.

In operation, the core is held in tension by the spacer.
