To the question of the treatment of malformation of the leg bones in combination with popliteal pterygium

The technique for the treatment of crus malformation accompanied by popliteal pterygium is suggested. The method consists of three stages. First stage is the lengthening of m. gastrocnemius and dissection of tape and cord-like bands. In the second stage hinge distraction device is applied and asymmetric distraction is performed, then pterygium popliteal fold is distended and incorrect position of the limb is eliminated. During the third stage the additional foot is resected and ligaments of knee joint are created from the muscular tendon of the additional foot.
