摘要:
FIELD: medicine.SUBSTANCE: group of inventions relates to medicine, namely to traumatology and orthopedics. Universal prosthesis of vertebra body for treatment of fracture-dislocations and stabilisation of cervical spine contains hollow tubular element, connecting threaded bushings, direction of thread on the ends of tubular element and, respectively, in threaded bushings is opposite, support sites, in which surface facing vertebra bodies are made porous. In the middle part of hollow tubular element made is cylindrical thickening, on whose external surface, at the same level, with the same step, located are even number of radial through holes. On one of the ends of hollow tubular element made is cross-like groove, threaded bushings are made one piece with support sites, whose external surfaces have pointed "saw"- and "grater"-like projections. From the side of cross-like groove location threaded bushing is made straight-through, and has mushroom-like shape, and on the opposite side of hollow tubular element - in form of composite cylinder, which has head and base, connected with ring by means of longitudinal posts. In upper part of composite bushing base made is T-shaped projection, whose protruding side parts are guides for slots of respective form, located in the lower part of head. Head and base of composite cylinder are connected by means of threaded rod, which has smooth ends, whose diameter is smaller than diameter of middle threaded part of rod. One end of rod is provided with blind hole for butt end key, is located in straight-through bushing, which has thread on external side surface, and groove on the butt end. Rod with bushing is installed in through hole in composite cylinder, perpendicular to its longitudinal axis. Thread for threaded bushing is cut in hole only in the part, belonging to base, and thread for middle part of threaded rod - on the part, belonging to composite cylinder head. On side surface of one of said longitudinal posts made is through
