The third stage consists in substituting the articulation of the wrist for the epicondyle.
These two processes, indeed, project backwards; the epitrochlea always remaining more developed than the epicondyle.
The epitrochlea is prominent; the epicondyle is surmounted by a well-marked crest, curved and flexuous in outline.
On this account they designate the external prominence as the epitrochlea, and the internal one as the epicondyle.
The epicondyle and the epitrochlea are somewhat different from those of the human bone.
Up to the age of seventeen or eighteen the epiphysis of the epicondyle may be separated.
For the arrangement of the epicondyle and the epitrochlea, see p. 30.
In making the forward movement of the body, the epicondyle must resume its natural place.
For this reason the epicondyle is called the eye of the arm.
epicondyle ep·i·con·dyle (ěp'ĭ-kŏn'dĭl, -dl)
A rounded projection at the end of a bone, located on or above a condyle and usually serving as a place of attachment for ligaments and tendons.
