removing a portion of a first phalangeal bone of a patient, a portion of second phalangeal bone, and a natural joint between the first phalangeal bone and the second phalangeal bone,
inserting a proximal end of an orthopaedic prosthesis into the first phalangeal bone, and
inserting a distal end of the orthopaedic prosthesis into the second phalangeal bone,
wherein the orthopaedic prosthesis includes an inner frame comprising a plurality of tessellated polyhedrons, wherein the plurality of tessellated polyhedrons of the inner frame define an open-cell structure, and wherein the open-cell structure comprises a dorsal surface, a palmar surface, and a three-dimensional inner open-cell structure that extends between the dorsal surface and the palmar surface, wherein the open-cell structure includes a central joint connecting the proximal end and the distal end, a first groove formed in a dorsal end of the central joint, and a second groove formed in a palmar end of the central joint positioned opposite the first groove to permit flexion motion between the proximal end of the orthopaedic prosthesis and the distal end of the orthopaedic prosthesis, and an outer shell that encases the inner frame, the outer shell extending from the proximal end to the distal end over the inner frame including the central joint.
