ICD-10: M86.09

Acute hematogenous osteomyelitis is a serious bone infection that occurs when bacteria spread through the bloodstream to the bone, leading to inflammation and infection. The ICD-10 code M86.09 specifically refers to acute hematogenous osteomyelitis affecting multiple sites. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Acute hematogenous osteomyelitis is characterized by the sudden onset of infection in the bone, typically caused by bacteria that enter the bloodstream. This condition is most common in children but can also occur in adults, particularly those with compromised immune systems or underlying health conditions.

Etiology

The most common pathogens responsible for acute hematogenous osteomyelitis include:
- Staphylococcus aureus: This is the most frequently isolated organism, including methicillin-resistant strains (MRSA).
- Streptococcus species: These can also be involved, particularly in cases associated with trauma or surgery.
- Gram-negative bacteria: Such as Escherichia coli, especially in adults or those with specific risk factors.

Pathophysiology

The infection typically begins when bacteria enter the bloodstream, often following an infection elsewhere in the body, trauma, or surgery. Once in the bloodstream, these bacteria can localize in the bone marrow, leading to:
- Inflammation of the bone and surrounding tissues.
- Formation of pus and necrotic tissue.
- Potential for abscess formation, which can further compromise blood supply to the affected area.

Symptoms

Patients with acute hematogenous osteomyelitis may present with:
- Localized pain: Often severe and worsening over time.
- Swelling and tenderness: Around the affected area.
- Fever and chills: Indicating systemic infection.
- Reduced mobility: Particularly if the infection involves weight-bearing bones.

Diagnosis

Diagnosis typically involves a combination of:
- Clinical evaluation: Assessing symptoms and physical examination findings.
- Imaging studies: X-rays, MRI, or CT scans to visualize bone changes and abscess formation.
- Laboratory tests: Blood cultures to identify the causative organism and inflammatory markers (e.g., elevated white blood cell count, C-reactive protein).

Treatment

Management of acute hematogenous osteomyelitis generally includes:
- Antibiotic therapy: Initiated promptly, often intravenously, based on culture results and sensitivity testing.
- Surgical intervention: May be necessary to drain abscesses or remove necrotic bone tissue.
- Supportive care: Pain management and physical therapy to restore function.
