The fastener may be headless and may be configured to compress bone when driven into at least one bone and across a discontinuity formed by the bone. In an exemplary embodiment, the fastener includes a forward portion, a rear portion, a first thread having a plurality of revolutions in each of the forward and rear portions, and a second thread having a plurality of revolutions in the rear portion and none in the forward portion. The first thread may have a greater average lead in the forward portion than the rear portion. Revolutions of the first thread and the second thread may alternate with one another in the rear portion such that the rear portion is at least double-threaded.
