ICD-10: M86.452

Chronic osteomyelitis is a persistent bone infection that can occur due to various factors, including previous infections, trauma, or surgical procedures. The ICD-10 code M86.452 specifically refers to chronic osteomyelitis with a draining sinus located in the left femur. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Chronic Osteomyelitis

Definition

Chronic osteomyelitis is characterized by the inflammation of the bone and bone marrow, typically caused by a bacterial infection. This condition can develop after an acute osteomyelitis episode or as a result of continuous exposure to pathogens, often due to an open wound or surgical intervention.

Symptoms

Patients with chronic osteomyelitis may experience a range of symptoms, including:
- Localized Pain: Persistent pain in the affected area, which may worsen with movement.
- Swelling and Redness: Inflammation around the site of infection, often accompanied by warmth.
- Draining Sinus: The presence of a sinus tract that allows pus or other fluids to drain from the infected area, which is a hallmark of chronic osteomyelitis.
- Fever and Malaise: Systemic symptoms may occur, although they are less common in chronic cases compared to acute infections.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies. Key diagnostic methods include:
- Physical Examination: Assessment of symptoms and examination of the affected area.
- Imaging Studies: X-rays, MRI, or CT scans can help visualize bone changes and the extent of the infection.
- Laboratory Tests: Blood tests may reveal elevated white blood cell counts or inflammatory markers, while cultures from the draining sinus can identify the causative organism.
