Osteonecrosis due to previous trauma, left fibula
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis, also known as avascular necrosis, occurs when there is a loss of blood supply to the bone, leading to the death of bone tissue. When this happens in the fibula—the smaller bone located on the outer side of the lower leg—it can cause pain, joint issues, and structural problems. The ICD-10 code M87.265 specifically pertains to osteonecrosis that has developed in the left fibula following an earlier injury or trauma. Recognizing and understanding this condition is essential for appropriate management and treatment planning.

Key Symptoms: Localized pain in the outer lower leg, especially worsened by weight-bearing activities Swelling or tenderness around the affected fibula Reduced range of motion or difficulty moving the ankle or lower leg Possible tenderness when pressing over the bone In some cases, there may be visible swelling or deformity if the bone weakens significantly
Diagnostic & Treatment
Diagnosis Path: Diagnosing osteonecrosis involves a combination of clinical examination and imaging tests. Healthcare providers typically use the following methods:
