Insights
Acute hematogenous osteomyelitis (AHO) is a serious bone infection, primarily caused by Staphylococcus aureus. Early diagnosis and prompt treatment, including antibiotics and surgery, are crucial to prevent severe complications in children.
Area of Science:
- Pediatric infectious diseases
- Orthopedic surgery
- Radiology
Background:
- Acute hematogenous osteomyelitis (AHO) is a bacterial bone inflammation.
- Neonatal osteomyelitis presents differently than in older children.
- Staphylococcus aureus is the primary causative agent in approximately 80% of cases.
Purpose of the Study:
- To highlight the emergency nature of AHO.
- To emphasize the need for early diagnosis and prompt, adequate therapy.
- To underscore the importance of interdisciplinary collaboration.
Main Methods:
- Review of diagnostic and therapeutic principles for AHO.
- Emphasis on early recognition and intervention.
- Symptomatic measures, bedrest, and operative intervention (drainage, debridement) when necessary.
Main Results:
- The lower extremities are most frequently affected.
- Proximal femur and humerus metaphyses carry a higher risk of septic arthritis.
- Successful outcomes depend on timely diagnosis and treatment.
Conclusions:
- AHO requires urgent medical and surgical management.
- Effective treatment involves antibiotics, surgical intervention, and supportive care.
- Preventing complications like septic arthritis, growth disturbances, and chronic osteomyelitis is paramount.
Abstract:
Acute hematogenous osteomyelitis (AHO) is an inflammation of bone caused by bacteria that reach the bone via the hematogenous route. Neonatal osteomyelitis differs from the disease in older children. Staphylococcus aureus is the most predominant organism, accounting for infection in about 80 % of patients. The lower extremities are most commonly affected. Because of the intracapsular metaphysis of proximal femur and humerus, there is a higher risk of concomitant septic arthritis in these joints. AHO always means an emergency with high diagnostic and therapeutic demands. The successful outcome depends on early diagnosis and prompt, adequate therapy. Therefore good cooperation with the pediatricians and radiologists is essential. The principles of treatment are symptomatic measures, bedrest and operative intervention, if necessary, with drainage of pus and débridement of any necrotic material, together with antibiotic treatment in sufficient concentration and for sufficient duration. The goal of treatment is to prevent complications such as concomitant septic arthritis with its high risk of persistent joint damage, growth disturbance or chronic osteomyelitis.
