Why Corns Aren't Normal

Corns and calluses are so common almost every person on this earth will experience one at some point in their life. Calluses are most often seen on the hands, but also form on the bottom of the feet and other various places. Corns are calluses that are seen on the tops and sides of the toes. These areas of thickened skin caused by focally increased pressure and rubbing are indeed benign. To people that use their hands for a living, calluses can actually provide extra cushion and blister prevention. Considering this, the prevalence of corns and calluses, and their often harmless etiologies many people assume it is normal to have them on their feet, like they do on their hands. However, this is simply not true. As aforementioned, corns and calluses are developed due to increased pressure and friction. While calluses on the hands often indicate manual labor or activities like rowing and lifting weights, on the feet the story is very different. While some people will wear gloves to prevent callus formation on the hands, many people do not, explaining the calluses. In contrast to this, the great majority of people wear socks and shoes during labor and exercise, yet how can areas of hyperkeratosis (thickened skin) be explained if they have a protective barrier (socks and shoes) in place? This is due to an abnormal foot architecture, or poorly fitting footwear.

A classic example of this abnormal architecture is the hammertoe. The actual shape of the toe has changed due to a few different possibilities causing the toes to become contracted in the shoebox, encouraging rubbing, and overtime corn formation. Hammertoes certainly are not the only cause of corns. They are simply one commonly encountered example of an underlying foot problem that has caused an excess of skin formation that may often be disregarded as normal. The recommendation here is to avoid the home remedies that simply treat the corn or callus, and not the underlying cause of the hyperkeratosis itself. A lot of resources can be consumed without even treating the cause.  If you have corns or calluses on your feet and/or toes make an appointment with a Podiatrist like Dr. Michael Garvin. He can evaluate your feet and your footwear, determine the actual etiology, and set up a treatment plan with you.

The following is a short list of conditions that commonly cause corns and calluses on the feet and toes:

Claw toes
Hammer toes
Mallet toes
Curly toes
Bunions
Tailor’s bunions
Pes Cavus
Pes Planus
Haglund’s deformity
Talipes Equinus

Claw Toe

A claw toe is a deformity of the toe that is due to a soft tissue (musculature) imbalance. Claw toes most often present with a callus and/or pain at the ball of the foot, and on top of the toe at the most proximal joint.  The imbalances that cause this physical change in shape of the toe are extension at the metatarsophalangeal joint, flexion at the proximal phalangeal joint and flexion at the distal phalangeal joint. Normally, in healthy toes, there should be no extension or flexion at any toe joint during relaxation. However, in the claw toe, these series of musculature contractures are seen due to underlying pedal or bodily pathologies. These pathologies can include, but are certainly not limited to severe flat foot deformity (pes planus), excessive pronation, trauma to the foot, diabetes mellitus, Charcot-Marie-Tooth disease, multiple sclerosis, rheumatoid arthritis, cerebral palsy and more. 

If you think you have a claw toe(s), or suffer from any of the aforementioned diseases you should have your feet checked out by a podiatrist. Dr. Michael Garvin of Port St. Lucie, Florida has been practicing for years and has great experience at treating claw toes and many other pedal pathologies. His aim is always to treat the underlying cause of foot pain with minimally invasive techniques. Visit Dr. Garvin’s website for more information regarding his practice and treatment options.

What are Corns and Calluses?

Corns and calluses are both formed by hyperkeratosis. This term simply means a thickening of the skin. These can form on many of the superficial surfaces of the body (most commonly on the feet!) for a variety of reasons. Typically, corns are sore and painful due to the friction that is occurring at the site, which is also their cause. Calluses are also caused by a thickening of the skin, but are more often associated with the excess synthesis of skin at a site as a protective mechanism. For example, many people develop calluses on their hands due to repetitive work like gardening. Calluses are also formed at areas of abnormal bony synthesis like bones spurs. 

Why should you be concerned about a Corn or Callus?

Hyperkeratosis certainly isn’t a reason to visit the emergency room. However, it is an important concern because it means that excessive use, and abnormal friction is occurring at that localized area of epidermis (most outer layer of skin). This is not only a cosmetic issue, but is often times painful and debilitating depending on severity. More importantly than the buildup of skin itself though, is the actual cause of the localized hyperkeratosis. This excess production of localized dermis is generally due to things such as poor fitting shoes, abnormalities of the toes, like hammertoes, unusual bony prominences such as bunions, and abnormalities of an individual's gait. All of these conditions are great reasons to setup an appointment with Dr. Michael Garvin! His goal is to empathetically alleviate his patient’s foot ailments with as minimally invasive procedures as possible.
