| Oblique or even transverse fractures of the shaft or base of the metacarpals can occur in one or more metacarpals. |
| The distal row of carpals includes the hamate, capitate, trapezium, and trapezoid, which are closely approximated to the metacarpals. |
| In the wing of archaeopteryx there are three long digits with distinct metacarpals. |
| There are eight carpal bones in the wrist, five metacarpals, and 14 nonsesamoid bones that comprise the phalanges. |
| These bones are the right size and shape, and in the right position, to be provisionally identified as metacarpals. |
| The tendons are inserted either into the corresponding extensor tendons or onto the metacarpals. |
