FIELD: medicine; medical engineering. SUBSTANCE: method involves measuring patient talonavicular angle. A through canal is built in the talus cervix and body so that one of inlet openings is placed on the internal surface of the talus cervix and the second one on the posterior surface of the talus body. Longitudinal canal axis is at an angle to the longitudinal talus axis, the angle magnitude differing from the measured talonavicular angle not more than by 5deg. Fixing member is introduced via the canal built in the talus block. Fixing member end is attached to the talus near the inlet opening of the canal located on the internal surface of the talus cervix. The second end is brought to the external surface of the calcaneus via the inlet opening on the posterior surface of the talus block. Pulling is carried out at brought-out free end of the fixing member from forwards in backward direction, from inside to outside until the longitudinal axes of the stretched fixing member and foot bone which longitudinal axis direction characterizes longitudinal foot axis of valgus displacement degree at an angle which magnitude differs from preliminarily measured talonavicular angle not more than by 5deg is reached. Through canal in the calcaneus is formed so that its inlet opening is located at the point of intersection of stretched fixing member longitudinal axis and external calcaneus bone plane and the outlet opening being placed on the internal surface of the calcaneus body. The fixing member is sutured with surgical suture. The suture threads and the fixing member are successively brought through a canal built in the calcaneus in the direction from outside to inside with thread ends and fixing member end brought via the outlet canal opening to the internal surface of the calcaneus. The brought-out free ends of the fixing member and surgical suture threads are pulled to achieve longitudinal talus axis and foot bone which longitudinal axis direction characterizes longitudinal foot axis valgus displacement degree relative to each other at an angle which magnitude corresponds physiologically normal magnitude of an angle between the longitudinal axes of the mentioned bones. Free end of the fixing member is fixed and its excessive portion is removed. EFFECT: excluded pathological mobility of the talus retaining its normal physiological mobility. 15 cl, 2 tbl
