摘要：
FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics and is intended for elongation of hip bone in children and teenagers with possibility to restore biomechanical interrelationships of extremity segments. Device contains supports in form of arch-shaped plates, thread bars, connecting supports, intraosseous rods and rod-fixers. Arch-shaped plates are bent on radius in their own plane, and are bent away in said plane in form of protrusions from end parts of plate towards its convexity. Protrusions and end parts of plate are provided with holes with bilateral countersunk. Along plate made are holes located on radius. Rod-fixers are made in form of prism, for installation in them of thread rods, with possibility to fix the latter with nuts. On lateral surface of prism installed it square boss for fixation of rod-fixers by means of screw with washer in support. Holes along plate are made in form of arch-shaped slots. Plate arches and said slots are arches of circumferences whose centre coincides with hip axis. Holes located in end parts of plate are intended for medial thread bars. Holes in protrusions have spherical countersunk and are intended for lateral thread bars. There are two pairs of bars in apparatus. Each of medial pair of bars consists of two bars, connected by means of hinge, with possibility of regulation and fixation in the place of junction with bolt with nut. Lateral bars are made one-piece and are connected with supports by means of nuts which have spherical contact surfaces. Medial bars are connected with supports by means or ordinary nuts.EFFECT: invention ensures elongation of hip bone with reconstruction of correct interrelationship of low extremity segments in sagittal and frontal planes, without additional surgery, with reduction of trauma, with increase of patients comfort for treatment period, with improvement of treatment results.2 dwgИзобретение относится к медицине, а именно к травматологии и ортоп
