Spring has sprung! We have recently been focusing our series on pressure ulcers that occur because of immobility. Now we will focus on a common skin condition caused by too much mobility: calluses. Are they friend or foe? Conventional thought says that we should just keep doing this and our skin will toughen up. IF you have normal sensation and circulation, calluses can just be thickened layers of skin that come with repetitive activity.

They initially protect the skin from breakdown.

Arterial Ulcers

What about those who have peripheral neuropathy, loss of protective sensation in the foot? What about those with peripheral arterial disease or decreased blood supply to the foot? Are calluses safe for these feet? What is a callus? There are 2 types of pressure on feet: Direct pressure: standing, weight bearing pressure Friction: resistance between two surfaces rubbing together.

Remember: pressure wounds are caused by tissue usually stuck between a rock and a hard place — the bone and the callus. No oxygen can get to the tissue and so it erodes and can cause a wound. Callus can actually be a pre-ulcerative lesion. Many times there are speckles of bruising or blood in the callus and it is actually hiding a wound beneath it. What is going on inside the skin? Take a look at these next photos: this first one shows a problem occurring in the most common area for calluses.

This woman came in with a large diabetic foot ulcer over the ball of her foot. Over the last ths the 4th and 5th metatarsal headsshe has calluses. She could not feel her feet due to neuropathy.

Her open wound itself was clean, non-infected, and pretty superficial. Now take a look at these next two close-ups: they are the same picture, a side view of a callus seen from the inside out. The callus is white because it is moist. Look at the thickness of those built up layers! Left unattended, that callus would have bore a hole through the outer layers of the skin and cause more wounding.

When this woman came in, we removed the layers of callus by debridement and gave her good pressure relief.

Neuropathic Ulcers and Wound Care: Symptoms, Causes, and Treatments

Here is the good news! This photo was taken just 2 weeks later: her wound has closed and her calluses are much less! Prevention is the key — as with any pressure problem.

Calluses are reduced when pressure is redistributed on softer, more pressure tolerant areas of the feet with the right inserts and shoes. We all come in different shapes and sizes. See a foot specialist to evaluate your feet and to get properly fitted inserts and shoes to give your foot the right support from a podiatrist or a pedorthist.

If you cannot feel your feet, they will not alert you to a problem.Diabetic foot ulcers can begin in a mundane way. Next thing you know, you have a small callus or blister on your foot.

The problem arises when you lose feeling in your feet. If you keep walking instead of stopping or changing shoes, a small sore may turn into a more serious wound. Up to 10 percent of people with diabetes will end up with a foot ulcer, podiatrist William Scott, DPMsays. These ulcers cause the skin to wear away, most commonly because of damaged nerves in the hands and feet peripheral neuropathyresulting from diabetes.

Although ulcers are sometimes dangerous and can lead to amputation, the key is prevention, Dr. Scott says. Typical wound care for a foot ulcer is debridement a doctor removes unhealthy tissue from the wound. Continued pressure on the sore will only worsen it. Infection and poor blood flow can lead to more serious complications, Dr.

That infection is what ultimately can lead to amputation. For this reason, you need to see your doctor quickly if you suspect you have a foot ulcer. Your doctor may order an X-ray, and possibly an MRI, if you have an ulcer that is worsening. This will show whether there is any infection in the bone. As time passes, the chances of it healing decrease. Be sure to see your doctor right away. Share this article via email with one or more people using the form below.

It can also cause loss of feeling in the foot, so you can injure it and not know it. Poor blood flow or changes in the shape of your feet or toes may also cause problems. Although it can hurt, diabetic nerve damage can also lessen your ability to feel pain, heat, and cold. Loss of feeling often means you may not feel a foot injury. You could have a tack or stone in your shoe and walk on it all day without knowing. You could get a blister and not feel it.

You might not notice a foot injury until the skin breaks down and becomes infected. Nerve damage can also lead to changes in the shape of your feet and toes. Ask your health care provider about special therapeutic shoes, rather than forcing deformed feet and toes into regular shoes. Diabetes can cause changes in the skin of your foot.

At times your foot may become very dry. The skin may peel and crack. The problem is that the nerves that control the oil and moisture in your foot no longer work. After bathing, dry your feet and seal in the remaining moisture with a thin coat of plain petroleum jelly, an unscented hand cream, or other such products.

Do not put oils or creams between your toes. The extra moisture can lead to infection. Also, don't soak your feet—that can dry your skin. Calluses occur more often and build up faster on the feet of people with diabetes. This is because there are high-pressure areas under the foot. Calluses, if not trimmed, get very thick, break down, and turn into ulcers open sores. Never try to cut calluses or corns yourself—this can lead to ulcers and infection. Let your health care provider cut your calluses.

Also, do not try to remove calluses and corns with chemical agents. These products can burn your skin. Using a pumice stone every day will help keep calluses under control.Neuropathic ulcers form as a result of peripheral neuropathytypically in diabetic patients. Local paresthesias, or lack of sensation, over pressure points on the foot leads to extended microtrauma, breakdown of overlying tissue, and eventual ulceration.

In addition, neuropathy can result in minor scrapes or cuts failing to be properly treated and eventually developing into ulcers. Typically, peripheral neuropathy affects the sensory nerves responsible for detecting sensations such as temperature or pain; however, it can also affect the motor nerves responsible for the contraction of muscles.

Damage to motor nerves can cause minor muscle wastingresulting in the imbalance of flexor and extensor muscles to cause foot deformitiessuch as claw toes or prominent metatarsal heads the end of the long foot bone that is closest to the toe joint.

This then provides additional pressure points prone to ulceration. In addition to these irregularities, ulceration frequently occurs at common pressure points on the plantar bottom surface of the foot, such as at the hallux big toemetatarsophalangeal joint the aforementioned area between the long bones in the foot and typically the big or pinky toeor the heel.

Ulceration on the side of the foot is typically a result of poor-fitting footwear, whereas ulceration on the dorsum top of the foot is typically due to trauma. The wound margins will have a well-defined, punched-out lookand the surrounding skin will often be callousedwith depth of the wound typically depending on the thickness of the callous.

Often there will be undermining in the wound, our underlying pockets of infectionwhich can in turn lead to osteomyelitis infection of the bone or bone marrow if left untreated. The combination of pressure-related ischemia restriction in the blood supply and neuropathy can allow infection to escalate further before being treated compared to other types of ulcers.

The wound itself will typically be painless unless there is also infection or an arterial component to the ulcer. The limb will generally maintain a normal pulsebarring additional circulatory components to the ulcer.

As mentioned above, neuropathic ulcers are caused by repeated stress on feet that have diminished sensation. However, if the neuropathic ulcer is present in an area that suggests trauma and not at a pressure point, there must additionally be vascular impairment to lead to ulceration.

For this reason, neuropathy is a common factor in combination ulcers. Peripheral neuropathy is often a result of:. Some less common conditions that can lead to neuropathic ulcers are chronic leprosy, spina bifida, and syringomyelia. The wound should be thoroughly debrided down to healthy, bleeding tissue.

Often there is infection underneath the superficial layer of necrotic tissue, even extending down into the bone and bone marrow. Debridement allows for better assessment of the ulcer and any underlying infections, as well as providing a better healing environment. Ideally, the wound environment should be moist while healing, but also allowed to breathe. The exact properties of the dressing should be matched to those of the wound. One of the most essential components to effectively healing neuropathic ulcers is to reduce pressure on the affected area.

However, relieving pressure from the wound needs to be balanced with keeping proper circulation to the extremities, so excessive bed rest is not recommended. Contact casts can be used to decrease pressure of the affected area while allowing the patient to remain ambulatory. Therapeutic shoes are also available to serve the same purpose, but are typically used for prevention or to avoid recurrence as opposed to during treatment.

If the ulcer does not resolve after more conservative measures, surgery to correct deformities in the foot may be considered to remove excessive pressure. The following precautions can help minimize the risk of developing neuropathic ulcers in at-risk patients and to minimize complications in patients already exhibiting symptoms:.Arterial ulcers, also referred to as ischemic ulcersare caused by poor perfusion delivery of nutrient-rich blood to the lower extremities.

The overlying skin and tissues are then deprived of oxygen, killing these tissues and causing the area to form an open wound.

In addition, the lack of blood supply can result in minor scrapes or cuts failing to heal and eventually developing into ulcers. The arteries are responsible for carrying nutrient- and oxygen-rich blood to the various tissues in the body. Ischemia, which refers generally to a restriction in the blood supply, can lead to arterial ulcers when it stems from a narrowing of the artery or damage to the small blood vessels in the extremities.

Arterial ulcers are characterized by a punched-out look, usually round in shape, with well-definedeven wound margins.

Arterial ulcers are often found between or on the tips of the toes, on the heels, on the outer ankle, or where there is pressure from walking or footwear. The wounds themselves are characteristically deepoften extending down to the underlying tendons, and will frequently display no signs of new tissue growth. The base of the wound typically does not bleedand is yellow, brown, grey or black in color.

Often the limb will feel cool or cold to the touchand the extremity will have little to no distinguishable pulse. The skin and the nails on the extremity will also appear atrophic, with hair loss on the affected extremity, while also taking on a shiny, thin, dry, and taut appearance.

In addition, the base color of the extremity may turn red when dangled and pale when elevated. An additional sign of an arterial ulcer is delayed capillary return in the affected extremity. These ulcers are generally very painfulespecially while exercising, at rest, or during the night. A common source of temporary relief from this pain is dangling the affected legs over the edge of bed, allowing gravity to aid blood flow to the ulcerous region.

Arterial ulcers are distinguishable from venous ulcers in that venous ulcers present with redness and edema swelling at the site of the ulcer, and may be painless.

A number of risk factors may contribute to the development of an arterial ulcer including the following comorbidities and conditions:. Left untreated, arterial ulcers can lead to serious complications, including infectiontissue necrosisand in extreme cases amputation of the affected limb. The following precautions can help minimize the risk of developing arterial ulcers in at-risk patients and to minimize complications in patients already exhibiting symptoms:.

The primary goal of the treatment of arterial ulcers is to increase circulation to the area, either surgically or medically. Surgical options range from revascularization in order to restore normal blood flow to amputation and rehabilitation in patients who cannot be revascularized. As for non-surgical measures, modifying contributing factors can slow or stop the progression of the local ischemia.

Additionally, there are boots and pumps available to augment perfusion to the affected limb. The ischemic wounds themselves differ from other severe wounds in that the wound environment should be as dry as possible to decrease the risk of infection.

The use of cadexomer iodine around the wound margins is an option due to its absorptive properties. This polymer draws exudate and particulate matter from the wound, then when moist releases iodine, serving the dual purpose of cleansing the wound and fighting bacteria at the wound site. Topical antibiotic ointments, such as bacitracin and triple antibiotic, should be used sparingly as they can actually be toxic to cells.

Diabetic Foot Ulcers: Why You Should Never Ignore Them

Cleveland Clinic.Wound management involves a comprehensive care plan with consideration of all factors contributing to and affecting the wound and the patient. No single discipline can meet all the needs of a patient with a wound. Age related skin changes see comparison figures below-normal on the left, aging on the right include thinning and atrophy of epithelial and fatty layers.

Additionally, collagen and elastin shrink and degenerate, and dermal fibroblasts cease replicating, all resulting in thinner, drier and less elastic skin that heals more slowly. Previously called decubitus or bed sore, a pressure ulcer is the result of damage caused by pressure over time causing an ischemia of underlying structures.

Bony prominences are the most common sites and causes. There are many risk factors that contribute to the development of pressure ulcers. CMS recommends patients in LTC be assessed for risk on admission, weekly for the first four weeks then reassessed quarterly. Proper skin care is crucial and involves inspecting skin daily and an individualized bathing schedule, using warm not hot water and mild soap.

Avoid massage over bony prominences and use lubricants if skin is dry. Friction and shear need to be reduced. Friction is the mechanical force exerted when skin is dragged against a coarse surface while shear is the mechanical force caused by the interplay of gravity and friction.

This manifests as necrosis and undermining of the deepest layers Pieper Holistic assessment of a patient with a wound includes systemic factors, psychosocial factors, and local factors.

Systemic factors assess etiology, duration, and decreased oxygenation or perfusion of the wound as well as comorbid conditions, medications, and host infection of the patient. An assessment of the wound should be done weekly and be used to drive treatment decisions. Location Documentation of location indicating which extremity, nearest bony prominence or anatomical landmark is necessary for appropriate monitoring of wounds.

Hess Originally there were four stages I-IV but in February these stages were revised and two more categories were added, deep tissue injury and unstageable. Pressure Ulcer Staging Stage I - Intact skin with non-blanchable redness of a localized area, usually over a bony prominence.

Darkly pigmented skin may not have visible blanching; its color may differ from the surrounding area. Stage III - Full thickness skin loss. Slough may be present but does not obscure the depth of tissue loss. Stage IV - Full thickness skin loss with exposed bone, tendon or muscle. Slough or eschar may be present on some parts of the wound bed.

Often include undermining and tunneling. The area may be preceded by tissue that is painful, firm, mushy, boggy, warmer or cooler as compared to adjacent tissue. Base Tissues Assessing the appearance of tissue in the wound bed is critical for determining appropriate treatment strategies and to evaluate progress toward healing.

Keast et al. Slough - Soft, moist avascular tissue that adheres to the wound bed in strings or thick clumps; may be white, yellow, tan or green. Typically the surface is shiny and moist with a granular appearance. Extreme malodor, especially if accompanied by purulent exudates is suggestive of infection.

Most wounds do have an odor. The type of dressing can affect odor as well as hygiene and the presence of nonviable tissue Keast et al. Induration - Abnormal hardening of the tissue caused by consolidation of edema, this may be a sign of underlying infection.If you have diabetes, you probably know that you are more at risk for foot injuries.

One of the most common kinds of injuries that you might have heard of is a foot ulcer. But, you may not be as familiar with a certain kind of foot ulcer called a callous ulcer. A callous ulcer is a specific kind of ulcer that has a hard base and rigid walls. The inside of the ulcer is often filled with pale tissue. These ulcers commonly develop on the soles of the feet, or under the balls or heels. They vary in shape and size. Callous ulcers are chronic and tend to last a long time.

They may take months or even years to heal. When you put pressure or friction on your foot all the time, the skin may harden and form a callus. A callus, which you probably have had on other parts of your body such as your hands, is a thickened and hardened part of the skin or soft tissue.

callous ulcer treatment

This can happen when you repeat any kind of motion over and over, which is why you may have developed a callus on your hands after using gardening tools or even playing guitar, or on feet if your shoes don't fit correctly.

If left untreated, the callus will continue developing, killing healthy tissue. If you have diabetic neuropathy, you may not notice this is happening because you've lost feeling in your feet from blood vessel and nerve damage.

Prevention is key when it comes to callous ulcers. You can help stop them from forming with a few simple lifestyle changes:. Callous ulcers may sound unpleasant, but with planning and making some of these simple changes, you can keep your feet healthy. Interested in learning more about foot ulcers? You can get all the basics here. If you think you have a callous foot ulcer, contact your doctor immediately.

Treatment is different from person to person. If you have diabetes, make sure that you see a podiatrist at least once a year.
