Contemporary Evaluation and Management of the Diabetic Foot
Figure 3
Rocker bottom foot deformity secondary to Charcot disease. (a) X-ray image lack of ankle joint dorsiflexion resulting in an increased load to the forefoot. This in turn leads to collapse of the tarsometatarsal joint, which is the focus point between the forefoot and hindfoot. The arch has collapsed and appears to be almost inverted. (b) Charcot foot with rocker bottom has increased propensity to pressure ulcers formation and is often seen with the involvement of Lisfranc joint.
