摘要：
FIELD: medicine.SUBSTANCE: device is a vertically extended cylindrical hollow body hingedly connected to one of its end surfaces, on the distal end side, with a fastening assembly consisting of a horizontally extended area having a rectangular supporting protrusion with a shape and dimensions adapted to the groove of the modular stem body of the hip endoprosthesis, and locking screw through holes located on both sides. Inside the cylindrical hollow body there is a piston dividing its internal cavity into two - an upper and a lower, the latter has a terminal for connection to a hydraulic pump which provides reciprocating movements of the piston along the cylindrical body by introducing liquid into its lower cavity and removing the liquid therefrom, inside the upper cavity in its central part there is a hollow cylinder and a central rod element inside it rigidly secured from the distal end on the piston to provide their protrusion from the end surface of the cylindrical body during movement of the piston in its direction, on the side of the proximal end of the rod element there is a threaded portion formed for connection to a plate mounted on the crest of the ilium.EFFECT: stability of the installed structure during the implementation of dosed hip reduction, eliminating the risk of its displacement and additional traumatization of bone tissue while maintaining the standard functions of the joint in order to improve the life quality of the patient in the period between two surgical interventions.1 dwgИзобретение относится к медицинской технике, используемой в ортопедии. Дистракционное устройство для низведения бедра представляет собой вертикально вытянутое цилиндрообразное полое тело, шарнирно соединенное с одной из его торцевых поверхностей, со стороны дистального конца, с крепежным узлом, состоящим из горизонтально вытянутой площадки, имеющей прямоугольный опорный выступ с формой и размерами, адаптированными под паз тела модульной ножки эндопротеза тазобедренного сус
