They are a hardening of the skin layer more outside than it appears generally on bony zones, like for example the joint of the big toe of the foot (juanete).
Or, a painless hardening of the skin caused by the repeated pressure and the irritation (callus). This one commonly affects hands, feet and knees.
Complications
Backache, hips, knees or ankles caused by a change in the form to walk due to the serious incomodidad.
Prognosis
Normally curable if the underlying cause can be eliminated.
Causes
The calluses and juanetes form to protect a certain skin zone of the damage produced by the repeated irritation (estrujamiento grazes or).
The pressure causes that the cells of the irritated zone grow more quickly arriving at the supergrowth.
In the case of juanetes a deformation of the joint of the big toe exists, that does that the bone protruya towards the outside, when bending the finger on the others (Hallux Valgus), which causes the appearance of the callus on the same one, which in this case we denominated juanete.
Signs and symptoms
The most characteristic symptoms are:
Juanete: Small swelling, soft and painful that is born alongside or on the joint of the big toe of the foot. Juanetes measures normally of 4 to 10mm of diameter and has an armor-piercing core.
Callus: Rough and hardened zone of the skin that appears after the repeated pressure or the irritation. The zones more commonly affected are the feet, the hands and the knees.
The calluses in the plants of the feet are most problematic.
It is not necessary to confuse them with plantar warts, painful induraciones in the plant of the foot with a "central eye" more dark, had to a virus.
Factors of risk
Inadequate footwear.
Those people with professions that imply the pressure on the hands and the knees, as they are carpenters, writers, guitarists or tejadores.
Prevention

Not to wear footwear that adapts bad on the foot.
Whenever it is possible, to take some type of protection like for example gloves or kneepads.
Diagnosis and treatment
Diagnosis
The diagnosis is made by means of the visual inspection.

General measures
Eliminate the cause of the pressure if it is possible.
Reject the footwear that does not serve to him.
Use groups for juanetes or calluses to reduce the pressure on the irritated zones.
Pele or rubs the zone hardened with pumice stone to clear the callus. It does not cut it with a blade, it leaves is his doctor or his podólogo who does it. Soak the zone in tempered water to soften it before pelar it.
Pídale to its shoemaker who him thing a metatarsal bar on the shoe while juanete is cured to him.
The greater surgery of the Hallux Valgus reserve for the cases in that the big toe gets to mount on the other fingers of pié, or when is specially painful. It is a painful and little functional intervention, reason why it must resort to her in last instance.
In the case of plantar warts, for its elimination the medicine injection can be necessary in its base.
Medication
Once eliminated the superior layers of callus, pelando them one or twice to the day, it applies salicílica pomada of 5% or 10% without medical prescription. Soon cúbralo with adesiva tape.
