The eversion of the leg is probably associated with contraction of the biceps muscle.
This deformity, which consists in a combination of dorsiflexion at the ankle and eversion of the foot, is as common as pure calcaneus (Figs.

The attitude most often assumed is that of flexion, with or without eversion of the leg and foot.
When the shortening and eversion are excessive, they should be completely corrected under anæsthesia before the retentive apparatus is applied, any impaction that exists being undone.
That which suffers eversion or its converse is no limb, but only a sheath, a prepuce.
With their separation they must continue to be attached to each other at certain points, and thus undergo eversion at certain points.
The portal vein arises from the intestinal canal, collects into one trunk, and again ramifies in order to unite with the biliary ducts, which are only a ramified saccular eversion of the intestine.
The unclosed vascular system is not yet self-substantial, because it is a cæcal eversion of the intestine or inversion of the skin, being itself only a ramified intestine and skin.
In Fishes the internal organ of respiration is already indicated by a cæcal eversion of the pharynx, which is surrounded by the branchial arches.
