Paragraph Number

56

The MTP joint 250 includes an articular surface of the first metatarsal 110, an articular surface of the first proximal phalanx 130, and one or more layers of cartilage (not shown). In certain embodiments, the articular surface of the first metatarsal 110 is a natural articular surface 260 and the articular surface of the first proximal phalanx 130 is also a natural articular surface 270. Of course either surface (260, 270) or both surfaces (260, 270) can be artificial articular surfaces. "Articular surface" refers to a surface of a structure that is coupled to, and may cooperate with, other structures of a joint of a human or animal to enable movement of structures of the joint. A natural articular surface is an articular surface created as part of natural, or human facilitated, cellular growth and development of bones of a patient.
