Ankylosis of the ankle and intractable post-phlebitic ulcer]

One of the causes of the intractable nature of some leg ulcers is the stiffening, then the ankylosis of the ankle. The consequences of the ankylosis are secondary to the physiology of walking by suppression of the muscular pump of the calf and that of the foot. The treatment must be preventive and this is possible only if ankylosis is systematically looked for in every longlasting leg ulcer.
