A system and method for facilitating the fixation of bone fractures is disclosed. The head component includes a tip, cutting threads and mating threads which are inserted into the far cortex of the bone. A wire extends from the head component and exits from the near cortex. A cap device includes a tension spring, wherein the tension spring 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. Tension is then applied to the wire while the cap is tightened against or within the bone surface to apply an appropriate amount of pressure between the surfaces of the fracture. The excess wire beyond the cap can then be removed.
