The experience (126 patients) in the use of the suggested by O.V. Oganesyan modified hingedistraction device for the treatment of old foot dislocations and fractures of the ankle joint articular ends is presented. Perfection of the construction enabled to simplify the application of the device as well as makes it possible to put together the articular ends and their fragments either in one step or gradually, to maintain the width of the articular slit along the articular surface, to perform active and passive motions in the unloaded joint. When the apparatus is used the volume of open surgical interventions is reduced to the required minimum. Due to the device construction it is also possible to eliminate all types of ankle joint and foot deformities (varus, valgus, equinus, adduction, excavation). In 109 patients the follow up period ranged from 1 to 17 years: the overwhelming majority of cases (82%) showed the restoration of the ankle joint function.
