FIELD: medicine.SUBSTANCE: method includes an external-lateral access, oblique osteotomy of the external ankle-bone above the joint fissure with the dissection of soft tissues in its front part, turning the ankle-bone outwards with the preservation of the connection with soft tissues, excision of cartilages of injured joints, displacement of the external ankle-bone with overlapping the arthrodised area to a tight contact with the tibia, talus and calcaneus with the formation of a united bone block and its fixation, lateral and longitudinal compression with the restoration of the extremity axis. Soft tissues are dissected in the distal tibiofibular joint of the front part of the ankle-bone through the external-lateral access. Osteotomy is carried out from outside inwards and upwards. The formed united bone block is fixed by a blocking pin intraosteally through the sole surface of the foot, with the restoration of the extremity axis under EIA control, with its introduction through the calcaneus, talus and lower third of the tibia. Then two fixing screws are introduced through the metatarsal tubercle in the sagittal plane. Axial compression, fixation by means of two blocking screws in the frontal plane in the middle-lower third of the tibia are realised. Lateral compression is realised by means of one screw through the talus and the other - through the proximal end of the external ankle-bone into the tibia in the frontal plane.EFFECT: method eliminates the deformation of the foot and pain syndrome due to strong arthrodising of the ankle and subtalar joints and improvement of the talus vascularisation.3 dwg |
