The invention facilitates the fixation of bone fractures. In a particular embodiment, a method for fixing bone fractures comprises the steps of: inserting a head component coupled to a wire through a first bone portion and anchoring the head component in a second bone portion, inserting a cap over the wire toward the head component until the cap contacts the second bone portion, and applying pressure to the wire using a tensioner to reduce the distance between the first bone portion and the second bone portion. The excess wire beyond the cap can then be removed.
