Abstract
A locking tack for attaching a bone fixation device to a bone includes (a) an elongated body including a distal portion formed of a weldable material and sized to be received within a bore through a portion of a target bone and a proximal portion which, when the distal portion is in a desired position within a target bone, extends out of the bone; (b) a channel extending longitudinally through the elongated body from a proximal end thereof to a channel distal end within the distal portion of the elongated body; and (c) an engaging feature at a distal end of the channel configured to engage an extraction mechanism so that forces applied to the extraction mechanism are transmitted to the distal end of the elongated body.
