What is a Poorly Healing Foot Wound?
A poorly healing foot wound is a persistent sore or ulcer that takes longer than expected to heal. Such wounds can occur due to various factors, particularly in individuals with underlying health conditions like diabetes or poor circulation.
Symptoms of Poorly Healing Foot Wounds
- Prolonged wound presence (weeks or months).
- Increased pain, redness, swelling, or warmth around the wound.
- Foul odour or discharge.
- Formation of a black or yellowish layer (eschar) over the wound.
- Difficulty walking or discomfort in the affected area.
Causes of Poorly Healing Foot Wounds
- Diabetes: High blood sugar levels can damage blood vessels and nerves, impairing the body’s ability to heal.
- Peripheral Vascular Disease (PVD): Reduced blood flow to the feet can impede the delivery of oxygen and nutrients to the wound site.
- Infection: Bacterial or fungal infections can hinder wound healing.
- Neuropathy: Nerve damage can diminish sensation, making it challenging to detect and address wounds promptly.
- Pressure and Friction: Ill-fitting shoes or excessive pressure on specific areas of the foot can lead to the formation of wounds.
Complications of Poorly Healing Foot Wounds
- Infection can progress to cellulitis, abscesses, or even bone infections (osteomyelitis).
- Non-healing wounds may lead to tissue death (gangrene), requiring amputation.
- Chronic wounds can significantly impact quality of life and mobility.
Diagnosis of Poorly Healing Foot Wounds
Dr. Lim will conduct a thorough examination, assess your medical history, and may order imaging tests or cultures to determine the underlying cause. Monitoring blood flow to the affected area through tests like ankle-brachial index (ABI) or Doppler ultrasound is essential.
Treatment Options for Poorly Healing Foot Wounds
- Wound Care: Keeping the wound clean, moist, and protected is essential.
- Offloading: Reducing pressure on the affected foot can aid healing.
- Antibiotics: If an infection is present, antibiotics may be prescribed.
- Surgical Debridement: Removal of dead or infected tissue to facilitate healing.
- Angioplasty and Stenting: For patients with compromised blood supply, these procedures can improve blood flow to the wound site, enhancing healing.
