Charcot joints and neuropathic change

Description: Classically the Charcot joint comprises extremely dense bones with sclerotic joint margins which are grossly distorted.
In the lower limbs the causes for neuropathic change might be diabetes, inherited neuropathy, Vit B12 deficiency, neurosyphilis and leprosy. In the upper limbs one would add the associated sensory neuropathy that is found in syringomyelia.
