In Cierny-Mader classification for chronic osteomyelitis, a medullary osteomyelitis (Stage 1) with a compromised host due to diabetes and peripheral vascular disease is classified as:

• A Stage 1A
• B Stage 1C
• C Stage 2B
• D Stage 1B ✓

Explanation

Cierny-Mader classifies chronic osteomyelitis by anatomic type (1=medullary, 2=superficial, 3=localized, 4=diffuse) and host category (A=normal, B=compromised locally/systemically, C=treatment worse than disease). A patient with diabetes and PVD represents a B host (systemic compromise). Therefore medullary osteomyelitis in a compromised host = Stage 1B. Host category B includes local (prior surgery, radiation, vascular disease) and systemic compromise (malnutrition, immunosuppression, diabetes).
