ICD-10: M86.37

Chronic multifocal osteomyelitis, represented by the ICD-10 code M86.37, is a specific diagnosis that pertains to a chronic infection of the bone, particularly affecting multiple sites within the ankle and foot regions. This condition is characterized by the inflammation of bone tissue due to infection, which can lead to significant morbidity if not properly managed.

Clinical Description

Definition

Chronic multifocal osteomyelitis is a persistent infection that affects multiple areas of the bone, often resulting from a variety of infectious agents, including bacteria. The term "multifocal" indicates that the infection is not localized to a single site but rather affects several areas simultaneously, which can complicate diagnosis and treatment.

Etiology

The etiology of chronic multifocal osteomyelitis can vary, but it is often associated with:
- Bacterial Infections: Common pathogens include Staphylococcus aureus and other bacteria that can enter the bone through open fractures, surgical procedures, or hematogenous spread from other infections.
- Underlying Conditions: Conditions such as diabetes mellitus, immunosuppression, or peripheral vascular disease can predispose individuals to osteomyelitis due to compromised blood flow and immune response.

Symptoms

Patients with chronic multifocal osteomyelitis may present with a range of symptoms, including:
- Localized Pain: Persistent pain in the affected areas of the ankle and foot.
- Swelling and Redness: Inflammation around the infected sites.
- Fever: Systemic signs of infection may be present, although they can be less pronounced in chronic cases.
- Drainage: In some cases, there may be drainage of pus or other fluids from the affected areas.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies:
- Imaging: X-rays, MRI, or CT scans can help visualize bone changes, including areas of necrosis or abscess formation.
- Laboratory Tests: Blood tests may reveal elevated inflammatory markers, and cultures can identify the causative organism.

Treatment

The management of chronic multifocal osteomyelitis often requires a multidisciplinary approach, including:
- Antibiotic Therapy: Prolonged courses of antibiotics are essential to eradicate the infection, tailored based on culture results.
- Surgical Intervention: In some cases, surgical debridement may be necessary to remove necrotic tissue and drain abscesses.
- Supportive Care: Addressing underlying conditions and providing pain management are crucial for recovery.

Prognosis

The prognosis for patients with chronic multifocal osteomyelitis can vary based on several factors, including the extent of the infection, the presence of underlying health issues, and the timeliness of treatment. Early intervention often leads to better outcomes, while delays can result in chronic pain and functional impairment.

In summary, ICD-10 code M86.37 encapsulates a complex condition that requires careful diagnosis and management to prevent complications and promote healing. Understanding the clinical aspects of chronic multifocal osteomyelitis is essential for healthcare providers to deliver effective care and improve patient outcomes.

Chronic multifocal osteomyelitis (CMO) is a rare inflammatory bone condition characterized by the presence of multiple osteomyelitic lesions, often affecting the long bones and, in some cases, the ankle and foot.
