L97.404
Non-pressure chronic ulcer of unspecified heel and midfoot with necrosis of bone
Clinical Classification Guidelines
Medical Intelligence & Overview
A non-pressure chronic ulcer of the heel and midfoot with necrosis of bone is a severe type of skin wound that develops on the heel or midfoot area and extends deep into the tissue, affecting the underlying bones. Unlike pressure ulcers caused by prolonged pressure, this ulcer arises due to other factors such as poor circulation, trauma, or underlying conditions. The presence of bone necrosis indicates that the affected bone tissue has begun to die, which can complicate healing and may require specialized treatment.
Causes & Symptoms
Clinical Causes: Poor blood circulation or peripheral vascular disease Diabetes mellitus leading to neuropathy and reduced healing capacity Trauma or injury to the heel or midfoot area Prolonged pressure not caused by weight or bed rest Infections that weaken skin and bone tissue Underlying conditions impairing tissue repair
Key Symptoms: Persistent open sore or wound on the heel or midfoot Deep-seated pain not relieved by typical treatments Black or discolored tissue indicating necrosis Swelling and redness around the wound Foul odor emanating from the ulcer Possible drainage or pus from the wound Reduced sensation in the affected area (neuropathy) Difficulty walking or bearing weight
Diagnostic & Treatment
Diagnosis Path: Diagnosis of this condition involves a comprehensive medical examination, including wound assessment and history. Imaging tests, such as X-rays, MRI, or bone scans, help determine the extent of tissue and bone damage and confirm necrosis. A biopsy may be performed to rule out infection or cancerous changes. Blood tests are also used to assess underlying health issues that may impair healing.
Treatment Protocols: Managing this type of ulcer usually requires a multidisciplinary approach. Treatment strategies include:
