Stage classifications, types of joint destruction, and bone scintigraphy in Charcot joint disease.

The histories of 36 Charcot joints (including four fractures) in 22 patients were investigated and a new stage classification system (Stage I-III) was introduced. Scintiscanning showed the uptake magnitude of radioactive substance in the Charcot lesions ranged from 6-22 times that of normal areas.
