ABSTRACT:
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.
