Abstract:
A bone fixation device, for securing a first bone fragment to a second bone fragment, comprising:an elongate pin, having a proximal end, a distal end and a first retention structure; at least one distal anchor carried by the elongate pin; and a proximal anchor, axially moveable with respect to the elongate pin and comprising a second retention structure; wherein at least a portion of the second retention structure is moveable between a first position and a second position, the second position being located closer to a longitudinal axis of the elongate pin as compared to the first position so as to engage at least a portion of the first retention structure and prevent proximal movement of the proximal anchor with respect to the elongate pin while the first position allows distal movement of the proximal anchor with respect to the elongate pin; and wherein the proximal anchor comprises a tubular body axially slidably carried on the elongate pin, an annular flange that defines an angular bone contacting surface and a plurality of slots which define a plurality of lever arms.
