The ossicle located at the joint of the fourth metacarpal bone with the carpus

To these bones there is sometimes added a tiny ossicle [os sesamoideum] (N in figs. 1, 2), one of those which resembles a sesame seed (V, V, X in fig. 1) and is called shsamoeidh= by the Greeks. 49 At the external side [lateralis] of the joint of the metacarpal bone that supports the little finger with the eighth carpal bone, 50 there is a bone of this kind, as if meant to fill up an area which is left more or less vacant here because this metacarpal bone is unable to press completely upon the eighth carpal bone with its upper part and moves away slightly to the outside. This ossicle, when it is present, is seen separately to reinforce the joint and give some underpinning to the metacarpal bone that supports the little finger. In such a case as this the eighth carpal bone is also contiguous to this ossicle 51 as well as the bones I have just mentioned.
