L97.424

Clinical Causes: Diabetes mellitus leading to neuropathy and poor circulation Peripheral vascular disease reducing blood flow Trauma or injury to the heel or midfoot area Repeated minor injuries or pressure from ill-fitting footwear (though these are non-pressure ulcers, prior trauma can contribute) Infections that impair healing or cause tissue breakdown Poor glycemic control in diabetics

Key Symptoms: Persistent, non-healing ulcers on the left heel or midfoot Local redness or swelling around the wound Discoloration or necrosis (dead tissue) appearing as blackened areas Pain or tenderness, especially if infection develops Foul odor emanating from the wound Possible drainage or pus Signs of infection such as increased warmth, fever, or malaise

Diagnosis Path: Diagnosis typically involves a comprehensive physical examination of the affected foot, assessment of wound characteristics, and imaging studies such as X-rays to evaluate the extent of bone involvement and necrosis. Blood tests may be performed to identify infection or underlying conditions. The healthcare provider will consider the patient's medical history, including diabetes status and vascular health, to determine the severity of the ulcer and associated necrosis.

Treatment Protocols: Debridement: Removal of necrotic tissue to promote healing Infection control: Use of antibiotics if infection is present Offloading: Protecting the ulcerated area from pressure using specialized footwear or devices Blood sugar management: Tight control of blood glucose levels in diabetics Improving circulation: Techniques to enhance blood flow, possibly including vascular interventions Wound care: Regular dressing changes and advanced wound therapy if necessary Surgical intervention: In severe cases, amputation may be considered to prevent the spread of infection Patient education: Encouraging proper foot hygiene and regular foot examinations to prevent recurrence
