M87.875
Other osteonecrosis, left foot
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis, also known as avascular necrosis, occurs when blood flow to a bone diminishes or stops entirely. Without adequate blood supply, the bone tissue begins to die, which can lead to joint damage and deformity. When this condition affects the bones in the foot, it is classified under ICD-10 code M87.875 as 'Other osteonecrosis, left foot.' This condition can significantly impair mobility and quality of life if not diagnosed and managed early. In this guide, you'll learn about what causes osteonecrosis of the left foot, how it presents, ways it is diagnosed, and typical approaches to treatment.
Causes & Symptoms
Clinical Causes: Trauma or injury leading to disrupted blood flow to the foot bones Chronic use of corticosteroids, which can impair blood circulation Excessive alcohol consumption, affecting blood supply Certain medical conditions such as sickle cell disease, lupus, or gout Bone disorders or abnormalities that compromise blood vessels Radiation therapy to the foot area Other rare causes including blood clotting disorders and certain medications
Key Symptoms: Persistent pain in the affected foot, especially during weight-bearing activities Swelling and tenderness around the affected area Limited range of motion or stiffness in the foot joints Weakness or a feeling of instability in the foot Possible bone collapse or deformity over time Changes in the shape of the foot or visible swelling
Diagnostic & Treatment
Diagnosis Path: X-rays: Can reveal bone collapse, sclerosis, or cyst formation in advanced stages Magnetic resonance imaging (MRI): More sensitive in early detection, showing bone marrow changes before structural damage occurs Bone scans: Can help detect areas of decreased blood flow Computed tomography (CT) scans: Provide detailed images of bone structure and deformities
Treatment Protocols: Non-surgical options: Rest and limitation of weight-bearing activities to reduce stress on the affected foot Use of mobility aids such as crutches or braces to offload the joint Medications like pain relievers and anti-inflammatory drugs In some cases, medications to promote bone healing or improve blood flow Surgical options: Core decompression: Removing a portion of the inner bone to decrease pressure and stimulate blood flow Bone grafting: Transplanting healthy bone tissue to support regeneration joint replacement surgery: In advanced cases with joint destruction, partial or total arthroplasty Other interventions may include procedures to realign or stabilize the bone.
