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.
Claims7
A locking tack for attaching a bone fixation device to a bone, comprising:
- 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 such that the distal portion is configured to be welded to a bone fixation device inserted in the bone and a proximal portion which, when the distal portion is within the target bone, extends out of the bone;
- 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
- 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 to break a weld between the distal portion of the elongated body and the bone fixation device and remove the locking tack from the bone.
