The Charcot Restraint Orthotic Walker, or CROW, is a rigid boot designed to accommodate and support a foot with Charcot neuroarthropathy (CN).
CROW consists of a fully enclosed ankle/foot orthotic with a rocker-bottom sole. It is a common treatment used to minimize further deformity and prevent ulcer development after acute CN has calmed down.
CN occurs when bones and joints in the foot fracture, break up or pop out of place with minimal or no known direct injury. In the United States, this deformity most commonly occurs in people with diabetes. The foot first enters an acute stage of swelling, warmth and redness, that can be mistaken for an infection. Broken bones and dislocations can occur, causing severe deformities of the foot and ankle. Some patients develop pain or ulcers when the affected foot becomes deformed. CN can affect the other foot or happen again in the same foot. The foot does not regain its normal shape.
