ICD-10: M86.351

Chronic multifocal osteomyelitis (CMO) is a rare, inflammatory bone condition characterized by the presence of multiple lesions in the bone, often affecting children and young adults. The ICD-10 code M86.351 specifically refers to chronic multifocal osteomyelitis localized in the right femur. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and management.

Clinical Presentation

Overview of Chronic Multifocal Osteomyelitis

Chronic multifocal osteomyelitis is distinct from acute osteomyelitis, primarily due to its chronic nature and multifocal involvement. It typically presents with bone pain, swelling, and tenderness, and may be associated with systemic symptoms such as fever and malaise, although these are less common in chronic cases.

Signs and Symptoms

1. Localized Pain: Patients often report persistent pain in the affected area, which may worsen with activity or pressure. In the case of the right femur, this pain can be localized to the thigh and may radiate to the knee or hip.

2. Swelling and Tenderness: The affected femur may exhibit swelling, warmth, and tenderness upon palpation. This can be accompanied by a noticeable increase in local temperature.

3. Limited Range of Motion: Patients may experience restricted movement in the hip or knee joint due to pain and swelling, which can affect daily activities.

4. Systemic Symptoms: While less common, some patients may present with low-grade fever, fatigue, and malaise, indicating a systemic inflammatory response.

5. Bone Changes: Radiological imaging often reveals characteristic changes such as bone lesions, cortical thickening, and possible sequestrum formation, which are indicative of chronic infection or inflammation.

Patient Characteristics

• Age: CMO predominantly affects children and young adults, typically between the ages of 2 and 25 years. However, it can occur in older adults as well.

• Gender: There is a slight male predominance in cases of chronic multifocal osteomyelitis.

• Underlying Conditions: Patients may have a history of immunocompromising conditions, such as diabetes or chronic inflammatory diseases, which can predispose them to bone infections.

• Previous Infections or Trauma: A history of prior infections, trauma, or surgical procedures involving the femur may be relevant, as these factors can contribute to the development of osteomyelitis.

Diagnosis and Management

Diagnosis of chronic multifocal osteomyelitis typically involves a combination of clinical evaluation, imaging studies (such as MRI or CT scans), and laboratory tests to rule out other conditions. Treatment often includes:

• Antibiotic Therapy: Long-term antibiotic treatment is essential, especially if there is evidence of bacterial infection.

• Surgical Intervention: In some cases, surgical debridement may be necessary to remove necrotic bone tissue or to drain abscesses.

• Pain Management: Analgesics and anti-inflammatory medications are commonly used to manage pain and inflammation.

• Monitoring and Follow-Up: Regular follow-up is crucial to assess treatment response and to monitor for potential complications.
