L97.22

Clinical Causes: Poor blood circulation, especially peripheral artery disease (PAD) Venous insufficiency, where blood flows improperly through veins Diabetes mellitus, which impairs healing processes Trauma or injury to the calf skin, even minor injuries that don’t heal properly Skin infections or inflammatory conditions Previous ulcers or wounds in the same area Smoking, which negatively affects blood flow Obesity, adding pressure and impairing circulation Chronic health conditions that impair tissue repair Nutritional deficiencies, especially proteins and vitamins necessary for healing

Key Symptoms: Persistent open sore or wound on the calf Surrounding skin may be discolored, red, or swollen Moist or weeping skin near the ulcer Pain or tenderness around the affected area Possible presence of pus or signs of infection Hardening or thickening of the skin around the ulcer Delayed healing despite treatment efforts Heaviness or aching in the calf

Diagnosis Path: Physical examination of the ulcer and surrounding skin Medical history review to identify underlying causes Doppler ultrasound to assess blood flow in the affected limb Blood tests to check for infections, diabetes control, and other health conditions Imaging studies if necessary to evaluate blood vessels Wound cultures to identify infections

Treatment Protocols: Wound care, including cleaning, debridement (removal of dead tissue), and dressing changes Managing underlying conditions such as diabetes and circulation problems Compression therapy if venous insufficiency is involved Medications to treat infection if present Blood flow improvement strategies, possibly including medications or procedures Nutritional support focusing on adequate protein and vitamin intake Avoiding smoking and weight management Surgical interventions in severe or non-healing cases, such as skin grafts or vascular procedures Regular monitoring and follow-up to prevent recurrence
