Charcot's joints
Also known as:
Charcot’s arthrosis
Charcot's disease
Charcot's joint
Associated persons:
Jean-Martin Charcot
Description:
A degenerative disease with progressive destruction of the bones and joints within the foot, resulting from neurological disorders, including tabes dorsalis, leprosy, diabetic neuropathy, alcoholic neuropathy, syringomyelia, or other conditions involving disease or injury to the spinal cord. The condition is characterized by hypermobility and instability of the joint. Decalcification of bone on joint surfaces accompanied by overgrowth of bone, intraarticular fractures and loose bodies, dislocations, knock knees, bone fragmentation, and osteophytic formations are among the ususal findings. Pain is usually absent although there are sometimes painful joint swellings.
The condition is constantly aggravated by the loss of pain and hypermobility of the joints, which deprive the affected organ of natural protection from injuries. In the early phases of the disease process, the foot may look normal. As it develops, the foot will present with significant amounts of soft tissue swelling and color changes. There is usually no arch remaining and the foot will tend to have a prominent bulge in the arch area. The foot is hot, swollen and non-painful. Prevalent in males; onset usually after 40 years of age; usually, insidious onset.
