An intramedullary fixation assembly for bone fixation includes a first construct. The first construct includes a first tapered screw member fixated into a subchondral bone. The first tapered screw member is aligned along a first longitudinal axis and has a first head portion comprising a first aperture and a first shaft extending from the first head portion. Moreover, the first longitudinal axis of the first tapered screw member is aligned substantially parallel to an articular surface of a bone. The first construct also includes a first lag screw member aligned along a second longitudinal axis. The first lag screw member has a first bulbous portion and a second shaft extending from the first bulbous portion, wherein the first lag screw member is coupled to the first tapered screw member, and further wherein the second longitudinal axis of the first lag screw member is aligned generally along the length of the bone.

Intramedullary fixation assembly and method of use

An implant system and apparatus configured to permit motion of the wrist in at least one physiological direction, as well as in a dart thrower's motion, and constrain motion of the wrist in at least one non-physiological direction are provided. The implant according to one embodiment includes a distal component and proximal component. Each of the distal and proximal components includes a primary articulating portion and a secondary articulating portion. Primary and secondary articulating portions include at least one component having either a substantially convex or a substantially concave shape. The secondary articulating portion is configured to be radially and volarly disposed in relation to the primary articulating portion.
