Answer

Whenever possible, radiographs should be obtained with the patient bearing weight.

Bone scanning (not always ordered) may help differentiate between Charcot arthropathy and osteomyelitis. An indium-111 WBC scan often is used because it is more specific than the technetium-99m scan.

Magnetic resonance imaging (MRI) [10] allows anatomic imaging of the area and may help distinguish between osteomyelitis and Charcot arthropathy.

Doppler ultrasonography is used to rule out deep vein thrombosis.
