CHARCOT ANKLE - RADIOGRAPHS - DR KHAIRUL FAIZI MOHAMMAD



Xray of the ankle from the side.

(note the complete destruction. The ankle joint has completely disappeared. The talus has been totally destroyed leaving only the head. There is evidence of bone shards in the the synovial lining that we can seen on the xrays)





loss of alignment of the ankle joint seen on the xray.
(the ankle joint is completely destroyed)







Normal Ankle Xray.

(the left is an xray taken from the front and the right from the side)





Radiographs of an ankle that is affected by Charcot Arthropathy depends on the chronicity of the problem. Deformity and loss of normal alignment is the first this that strikes one's mind. Complete destruction of the ankle joint and the surrounding joints such as the subtalar joint and midtarsal joints maybe evident. We should also look for evidence of osteomyelitis (infection of the bone). This is very important, as this needs to be removed to prevent infection.

Charcot arthropathy is very difficult to clinical differentiate from septic arthritis (infection within the joint). Very frequently one can be mistaken for the other. Another investigation to help differential the two is a technitium 99 bone scan.

The diagnosis of Charcot arthropathy is made by a combination of clinical impression, radiological investigations (plain xrays and bone scan) and a positive finding of bone shards in the joint synovium (joint lining).
