L97.302

Clinical Causes: Poor blood circulation, especially in the lower limbs Diabetes mellitus, leading to peripheral neuropathy and poor wound healing Venous insufficiency, causing blood pooling and skin damage Trauma or injury to the ankle area Infections that impair wound healing Prolonged pressure or friction (though the ulcer is non-pressure, chronic mechanical irritation can contribute)

Key Symptoms: Open sore or wound on the ankle that persists for weeks or months Exposed tissue showing fat layer beneath the skin Swelling and redness around the ulcer Possible signs of infection such as pus, increased pain, or warmth Discoloration or changes in skin texture surrounding the ulcer Reduced sensation in the affected area if nerve damage is involved Potential foul odor from infected tissue

Diagnosis Path: Physical examination of the ulcer and surrounding skin Assessment of wound size, depth, and appearance Vascular studies to evaluate blood flow, such as Doppler ultrasound Blood tests to check for infection, blood sugar levels, and overall health status Imaging studies like X-ray if underlying bone infection or damage is suspected Biopsy if the wound does not heal as expected to rule out other conditions like cancer

Treatment Protocols: Proper wound care, including regular cleaning and dressing changes Debridement to remove dead or infected tissue to promote healing Management of underlying conditions such as diabetes or vascular issues Use of dressings that maintain moisture and protect the ulcer Offloading or immobilization to reduce pressure on the affected ankle Antibiotics if infection is present Advanced therapies such as bioengineered skin or growth factors in persistent cases Surgical interventions if necessary to repair tissue or improve blood flow Lifestyle modifications to support healing, including smoking cessation and maintaining good nutrition
