Abstract

See full text

Methods and devices are provided for facilitating delivery and implanting of a bone anchor into bone. In one exemplary embodiment, a bone anchor extension is provided for coupling to a bone anchor to facilitate delivery and implanting of the bone anchor in bone. The bone anchor extension can have a generally elongate configuration that allows it to extend from a skin incision in a patient to a site proximate a patient's spine, and it can include a lumen extending therethrough between proximal and distal ends thereof. A distal end of the bone anchor extension can be adapted to engage a bone anchor, such as a bone screw. Various techniques are provided for locking the distal end of the bone anchor extension into engagement with a bone anchor.
