First metacarpal bone a thin cortical shell. The head is less rounded and less spherical than those of the other metacarpals, making it better suited for a hinge-like articulation. The distal articular surface is quadrilateral, wide, and flat; thicker and broader transversely and extends much further palmarly than dorsally. On the palmar aspect of the articular surface there is a pair of eminences or tubercles which articulate with the radial and ulnar sesamoid bones of the thumb metacarpophalangeal joint; the lateral eminence is larger than the medial. The body or shaft is thick and broad — averaging . On its dorsal side, the
