ABSTRACT OF THE DISCLOSURE A flexible implant for replacement of the lunate bone of the wrist includes a one-piece body of resilient material defining a planar triquetrum face having a general U-shape in plan and further including a stabilizing stem extending outwardly from and perpendicular to the planar triquetrum face and a planar scaphoid face having a generally U-shape in plan extending at an angle with respect to the triquetrum face. The body further includes a cupped, concave, smooth distal surface adapted to articulate with the head of the capitate bone. The body defines a proximal surface having a smooth convex shape and extending between the proximal edges of the triquetrum and scaphoid faces. Generally, planar palmar and dorsal surfaces extend between the dorsal lateral edges and the palmar lateral edges of the triquetrum and scaphoid faces.
