A bone infection in the left shin bones (tibia and fibula) caused by bacteria spreading through the bloodstream.

• ✓Specific identification of left tibia and fibula involvement
• ✓Clinical symptoms supporting bone infection diagnosis
• ✓Radiological evidence of osteomyelitis in tibia and/or fibula
• ✓Laboratory findings consistent with bacterial infection
