Summary
Staphylococcal septicaemia can cause osteomyelitis with large sterile joint effusions, mimicking septic arthritis. Early diagnosis is crucial as initial X-rays may appear normal.
Area of Science:
- Orthopedics
- Infectious Diseases
- Radiology
Background:
- Osteomyelitis is a bone infection often caused by bacteria.
- Staphylococcal septicaemia is a bloodstream infection with Staphylococcus bacteria.
- Septic arthritis is a joint infection.
Observation:
- Two patients presented with osteomyelitis secondary to staphylococcal septicaemia.
- Both patients had large sterile effusions in joints adjacent to the infected bone.
- Clinical presentation suggested septic arthritis, with multiple joints affected in each patient.
Findings:
- Osteomyelitis, a bone infection, can manifest with significant joint effusions.
- Sterile effusions adjacent to osteomyelitis can mimic septic arthritis.
- Radiographs may not reveal abnormalities in early stages of this condition.
Implications:
- This presentation highlights the importance of considering osteomyelitis in cases of suspected septic arthritis, especially with sterile effusions.
- Advanced imaging may be necessary for early diagnosis when radiographs are inconclusive.
- Prompt identification and treatment are essential to prevent complications associated with both osteomyelitis and joint involvement.
