Abstract
Purpose — to evaluate the efficiency of the proposed method of arthrodesis by three cancellous screws in patients with posttraumatic arthrosis of the ankle joint.Materials and Methods. After removal of talus and tibia cartilage and autografting the proposed method features placement of foot into the optimal position and fixation of the ankle joint with three cancellous screws. 23 patients with posttraumatic ankle deformity arthrosis of grades III–IV underwent surgery according to the described procedure. Condition of all patients prior to and after the surgery was evaluated using the international ankle and rear foot assessment scale of the American Orthopedic Society of the Foot and Ankle (AOFAS).Results. In 20 patients (88%) the ankle ankylosis was reported within 2.5 months, which was confirmed by X-ray examination. In 2 patients (8%) the ankylosis took place in the period up to 4 months. Loss of the correct position of the foot with screws migration was reported in one patient (4%). The authors observed that patients with postoperative deviation of the tibiotalar angle not exceeding 5 degrees as compared to a healthy limb demonstrated the best functional outcomes.Conclusion. The suggested technique ensures a secure fixation of talus in a predetermined position, a single-step compression between the closed joint surfaces and allows an early effective rehabilitation.

Summary
Реферат Цель исследования — оценить эффективность предложенного способа артродезирования тремя спонгиозными винтами у пациентов с посттравматическим деформирующим артрозом голеностопного сустава. Особенность методики заключается в том, что после удаления хряща таранной и большеберцовой костей, оригинальной пластики аутологичной костью стопу выводят в оптимальное положение и фиксируют голеностопный сустав тремя спонгиозными винтами. Предложенным способом было прооперировано 23 пациента с посттравматическим деформирующим артрозом голеностопного сустава III–IV степени. У 20 (88%) больных костный анкилоз голеностопного сустава был достигнут в срок до 2,5 мес., что было подтверждено рентгенологическим исследованием, у 2 (8%) больных анкилоз состоялся в срок до 4 мес. У которых отклонение таранно-большеберцового угла не превышало 5° по сравнению со здоровой конечностью после операции, имели наилучшие функциональные результаты. Ключевые слова: посттравматический деформирующий артроз, артродез голеностопного сустава, спонгиозные винты, костная пластика, таранно-большеберцовый угол
