Foot Ulcer / Non-Healing Wound

A sore that lingers longer than a week, or worsens despite home care, is more than a nuisance. Chronic foot ulcers expose skin, fat, and sometimes bone to infection, risking serious complications. Our board-certified podiatrists combine advanced wound-care techniques with biomechanical off-loading and systemic management to close stubborn wounds and protect limb health.

What Is a Foot Ulcer?

A foot ulcer is an open lesion that penetrates through the full thickness of the skin. It most often develops beneath pressure points, the ball of the foot, heel, or tips of the toes, but can occur anywhere rubbing, trauma, or poor circulation damages tissue faster than it can heal.

Common Underlying Causes

Pressure & Trauma Vascular & Systemic Neurologic
Repetitive friction from ill-fitting shoes Peripheral arterial disease (poor blood flow) Diabetic peripheral neuropathy—loss of protective sensation
Bony prominence (bunions, hammertoes, heel spur) Chronic venous insufficiency or edema Charcot foot collapse altering weight-bearing
Unrelieved pressure in wheelchair or bed-bound patients Uncontrolled diabetes or kidney disease Post-surgical nerve injury

Hallmark Signs & Risk Indicators

  • Open sore with or without drainage ≥ 7 days
  • Surrounding callus rim or undermined edges
  • Skin that appears pale, yellow, or blackened (eschar)
  • Swelling, redness, warmth—possible early infection
  • Foul odor or purulent discharge
  • Loss of sensation—patient may not feel the wound develop
  • Previously healed ulcer that has re-opened in the same spot

Why Early Evaluation Matters

  • Infection prevention — bacteria can spread to deep tissues and bone (osteomyelitis).
  • Limb preservation — timely, expert wound care is the key factor in avoiding amputation.
  • Systemic health — chronic wounds elevate cardiovascular risk and diminish quality of life.

Comprehensive Wound Care at North Texas Podiatry Associates

Evidence-Based Components Advanced Technologies
Sharp debridement to remove necrotic tissue Bioengineered cellular skin substitutes
Total-contact casting or CROW walker for pressure off-loading Negative-pressure wound therapy (vacuum dressings)
Moisture-balanced dressings (hydrofiber, foam, alginate) Ultrasound-guided antibiotic beads for bone exposure
Weekly bacterial cultures & targeted antibiotics Hyperbaric oxygen therapy (co-managed)
Vascular work-up—ABI, Doppler ultrasound—plus referral if revascularisation needed Bone biopsy & imaging to rule out osteomyelitis

More than 85 % of neuropathic ulcers close within 12 weeks when aggressive debridement, off-loading, and glycaemic optimization are combined.

Our Treatment Philosophy

  • Root-cause correction We address pressure, blood flow, infection, and glucose control simultaneously.
  • Multidisciplinary coordination Seamless referral to vascular surgery, endocrinology, or infectious-disease specialists when required.
  • Patient empowerment Education on daily foot inspection, shoe selection, and blood-sugar targets prevents recurrence.

Frequently Asked Questions

Most ulcers need debridement and reassessment once per week until healthy granulation tissue fills the defect.

Any weight on a plantar (bottom-of-foot) ulcer delays healing. We supply casts or removable walkers that off-load pressure without sacrificing mobility.

Surgery is reserved for cases with bone infection, severe deformity causing repeated pressure, or when vascular bypass is necessary to restore blood flow.
