r classifications have been developed to emphasize different clinical
aspects of osteomyelitis, These classifications include those of Ger,
Kelly, Weiland, Gordon, May, and Cierny-Mader, The Cierny-Mader classi
fication is based on the anatomy of bone infection and the physiology
of the host. The Cierny-Mader classification permits the development o
f comprehensive treatment guidelines for each stage, The Cierny-Mader
classification is used to demonstrate the application of staging for t
