Claim Text:
1. A bone fixation device comprising: a stem that is elongate along a first direction and includes a first end and a second end that is spaced from the first end along the first direction, the stem further including at least one first tooth; a first fixation member fixed to the first end of the stem with respect to translation relative to the stem along the first direction; and a second fixation member including a body that defines an inner surface and an outer surface opposite the inner surface, the second fixation member including an internal surface that at least partially defines a slot that extends through the body from the inner surface to the outer surface, the slot being sized to receive the stem such that the second fixation member is slidable along the stem along the first direction, the second fixation member further including at least one second tooth that extends from the internal surface; and a biasing member having a flexibility greater than that of the internal surface, the biasing member configured to bias the stem toward the at least one second tooth when the stem extends through the slot such that the at least one first tooth engages the at least one second tooth so as to i) permit the at least one second tooth to slide along the at least one first tooth when the second fixation member translates along the stem toward the first fixation member, and ii) cause the at least one second tooth to interlock with the at least one first tooth to prevent the second fixation member from translating along the stem away from the first fixation member.
