    摘要: A device (404), for securing a first bone fragment (19) to a second bone fragment (21), comprising:
    an elongate pin (405), having a first retention structure (406);
    at least one distal anchor (34) carried by the elongate pin; and
    a proximal anchor (400) comprising a second retention structure (408), a tubular body (412), an annular flange (414), and a plurality of slots (416), the tubular body being axially slidably carried on the elongate pin, the annular flange defining an angular bone contacting surface (415), the plurality of slots defining a plurality of lever arms (418),
    wherein at least a portion of the second retention structure is moveable between a position located closer to a longitudinal axis of the elongate pin so as to engage at least a portion of the first retention portion and prevent proximal movement of the proximal anchor and another position which allows distal movement of the proximal anchor.
