Abstract:
1. A system for fixing at least one bone or joint from a proximal surface to a distal surface, comprising: a hollow implant body having a proximal end and a distal end terminating in a shaped spreadable end; a bone-boring bit on an elongated rotatable shaft, the bit having a distal surface with a burr or cutting edges and a proximal surface conforming to the shape of the spreadable end, such that when the bit extends through the implant body and past the distal end and the shaft is pulled in a proximal direction, the interaction of the proximal surface of the bit and the shaped, spreadable end of the implant body spreads the spreadable end to prevent backout of the implant body; and a proximal cap secured to the proximal end of the implant body thereby applying compression across the proximal and distal surfaces of the bone or joint.
