Abstract: A system and method for facilitating the fixation of bone fractures is disclosed. The anchor component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the anchor component and exits from the near cortex. A cap device includes a tension spring, a ratcheting mechanism, a lever clutch, and/or at least one wedge, wherein the tension spring, ratcheting mechanism, lever clutch, and/or at least one wedge is configured to assert friction against the wire when the cap is translated in one direction, but minimal friction against the wire when the cap is translated in the opposite direction. The cap is threaded over the wire such that the cap is restricted from backwards movement.
