Below-knee amputation for Charcot joint developing 40 years after spinal cord injury. Case report.

A Charcot joint developed following a spinal cord injury in a patient who had sustained a fracture-dislocation of the 12th thoracic vertebra and a spinal cord injury in a cave-in accident in a coal mine 40 years previously, and had since been assisted in walking with the aid of a short leg brace and a cane. Recently, the patient developed Charcot joints of the right knee and ankle, and the right ankle joint also became infected with a refractory open wound necessitating a below-knee amputation.
