Focusing on the ankle joint, he determined the angle of "dorsiflexion" - the degree to which the ankle rotates to point the toes upwards.
Point your toes as your legs swing forward this prevents dorsiflexion
In dorsiflexion, herefore, greater space is required between the two malleoli.
The movements of the joint are those of dorsiflexion and extension; dorsiflexion consists in the approximation of the dorsum of the foot to the front of the leg, while in extension the heel is drawn up and the toes pointed downward.
There is dorsiflexion at the ankle-joint, and if an attempt is made to flex the foot towards the sole, the extensor tendons stand out prominently.
Jones divides the tendo Achillis and the flexors of the toes subcutaneously, and maintains the dorsiflexion by excising an oval flap of skin from the front of the ankle.
In the _acquired form_, the appearances are different, because the anterior part of the foot is usually flexed towards the sole, thus disguising to a certain extent the dorsiflexion at the ankle.
When these measures are impracticable, the suffering may be relieved by inserting in the boot a rigid metal plate which will prevent any attempt at dorsiflexion in walking.
The lunate may be displaced forward by forcible dorsiflexion of the hand, and forms a projection beneath the flexor tendons; there is usually loss of sensibility in the distribution of the ulnar nerve in the hand.
As the disease progresses, the toe is drawn towards the sole and becomes permanently flexed -- _hallux flexus_ -- and any attempt at dorsiflexion is attended with pain.
