• ✓Specific identification of left femur involvement
• ✓Evidence of infection timeline spanning weeks to months
• ✓Clinical symptoms consistent with subacute bone infection
• ✓Radiological confirmation of osteomyelitis in left femur
• ✓Laboratory findings supporting ongoing infectious process
• ✓Culture and sensitivity results when obtainable
• ✓Functional assessment including mobility and weight-bearing status
