An intramedullary assembly for intraosseous bone fusion includes a lag screw member and a tapered screw member. The lag screw member includes a first elongated body, where the first elongated body includes a first threaded portion at a first end and a bulbous portion at a second end. The tapered screw member is coupled to the lag screw member, and the tapered screw member includes a second elongated body, where the second elongated body includes a second threaded portion at a third end, and an opening at a fourth end.

Intraosseous intramedullary fixation assembly and method of use

A method for applying compression to a joint includes providing an intramedullary fixation assembly having a proximal screw member positioned at a proximal end of the intramedullary fixation assembly and a lag screw member positioned at a distal end of the intramedullary fixation assembly. Medullary canals are drilled in a first and second bone and the medullary canals are reamed. The proximal screw member is inserted into the first bone and a drill is used create a dorsal hole in the first bone. The lag screw member is slideably coupled to the dorsal hole and to the proximal screw member and into the second medullary canal. A torque is applied to the lag screw member to apply compression to the joint.
