Foot Ulcers and Wounds

Ulcers are caused by the breakdown of skin leaving an open sore. The most common types of ulcers are venous ulcer, arterial ulcer and neuropathic ulcer. Wound care is necessary to ensure the open sore closes and heals properly

What is an ulcer?

An ulcer is an open wound in the skin that appears as an open crater and exposes the deeper tissue.  Ulcers are wounds that generally will not heal or keep reoccurring.

What does an ulcer look like?

  • Open sore exposing deeper tissue
  • Skin around sore may be red, swollen and painful
  • Fluid may ooze from the ulcer (blood or pus)
  • May have a swollen leg with burning or itching sensations

What are venous ulcers?

Venous ulcers are commonly seen above the calf or on the lower ankle.  Venous ulcers are most common in patients who have a history of swollen legs, varicose veins or a history of blood clots.

  • Shallow sore
  • Irregular shape
  • Usually appear on the lower leg and ankle
  • Associated with contact dermatitis
  • May/may not be painful

Risk factors for a venous ulcer are:

  • Deep vein thrombosis (blood clot)
  • Congestive heart failure
  • Varicose veins
  • Obesity
  • Long periods of sitting or bed rest
  • Pregnancy

What are arterial ulcers?

Arterial ulcers are commonly seen on the outside (lateral) part of the foot, ankle or leg. Arterial ulcers are most common in patients with very poor circulation and blood flow to the leg. When pressure is placed on the skin, due to foot structure or even ill-fitting footwear, the skin is damaged but unable to repair itself due to poor blood flow to the tissue, which can lead to an ulcer.

What are neuropathic ulcers?

Neuropathic ulcers are associated with patients who have lost their sensation to pain. Patients will typically exert a lot of pressure at certain spots under their feet when they walk creating a build-up of callus.  As time progresses, the pressure becomes so high that the callused area eventually breaks down and an ulcer is formed except the patient will hardly notice any pain.

Characteristics of a neuropathic ulcer are:

  • painless
  • surround by callus (thick, dead skin)
  • located typically around the bottom of the foot or the tips of toes

Risks for a neuropathic ulcer are:

  • history of foot ulcers
  • loss of sensation in the feet (neuropathy)
  • poor circulation
  • swollen feet
  • ill-fitting footwear

How do you treat leg ulcers?

Since every patient is unique and every ulcer is different, each patient’s treatment plan will be based on the type of ulcer, patient’s general health and ability to care for the wound.

The goal at Cooksville Foot Care Clinic is to ensure the necessary steps are taken so foot ulcers heal correctly.  Treatments will focus on relief of pain, speed up recovery and heal the wound.
