Definition of Corns
The corns are cutaneous thickenings observed at the zones of support of the soles of the feet and convexities of the toes. The corns are due to repeated rubbing, causing the thickening of the skin in response to chronic trauma.
Symptoms of corns
Corns usually take different forms depending on their s location s 1:
- On the soles of the feet, it is horny and thickened zones, located on the zones of support. We then speak more readily of callosities. They are sometimes centered on an area a few millimeters in diameter, harder than the callus and frequently painful, forming a kind of nail planted in the center of the callus and called callus.
- On the toes. The corns sit most often on the top of the toes. The inter-phalangeal joints that form natural convexities (accentuated in particular in case of deformation of the toes) rub in the shoes, hence the appearance of corns in these places. They are rough and round thickenings of the skin. They are sometimes centered on a darker area, giving them a target appearance. The corns can also be on the inner or outer sides of the toes (especially the last two). They are then called “partridge’s eye”. They are caused by a friction between two toes.
People at risk
People at risk are those with more than 30 years, as the foot begins to deform from 20-25 years. At this age the skin becomes less flexible and therefore more sensitive to friction and chronic trauma.
People with unsuitable shoes (high heels, safety shoes, etc …) or with deformities of the feet are the people most at risk.
The feet are subjected to many traumas because they carry the weight of the body. The factors favoring the appearance of corns are:
- the wearing of inappropriate shoes traumatizing (safety shoes, pointed shoes) or unbalanced foot (shoes with heel);
- The foot deformities (hammer toe, hallux valgus …).
The prevention of corns goes through the care of the feet and the limitation of the chronic traumas:
- Wear wide, comfortable and flexible shoes (canvas, soft leather, etc …) and avoid high heels and pointed toe shoes ;
- Lightly sand calluses and corns while bathing;
- Moisturize the skin of the feet with a moisturizer after the toilet;
- In case of calluses or proven corns, apply bandages (pads for calluses and perforated dressings for corns, type Elitist, Compeed, etc …).
If the prevention does not work and the corns or calluses are painful, consult your doctor. If the latter deems it useful, he may prescribe soles and / or orthotics (small removable pads to put on or between the toes) to be made by a pedicure-chiropodist, who can also:
- Practice pediatric care to thin the pathological areas (soft stripping on the scalpel blade);
- Perform a static podiatry assessment (standing footprint) and dynamic (walking), revealing foot support imbalances. He will provide you with orthopedic insoles if necessary. He can also make padsinter-toes in case of deformation of the toes or eye of partridge.
Many coricidal dressings based on salicylic acid (Urgo, Scholl, etc.) are available on the market, which soften the corns for pumice stripping.
In case of severe deformity of the feet (such as a hallux valgus) or toes, the doctor can refer his patient to an orthopedic surgeon to surgically reduce the osteo-articular anomalies sources of corn.
