Charcot joint in congenital pain insensitivity

AP (image 1), oblique (image 2), and lateral (image 3) radiographs of the foot in a patient with pain insensitivity show destruction of the medial cuneiform and dorsal and distal talus consistent with a Charcot or neuropathic joint. While diabetes is the most common cause of a Charcot joint in adults, other conditions are more prevalent in children. Radiographs can show destructive changes of the joint with bone fragmentation and debris. They most commonly affect the foot and ankle.
