    The acetabulum component of a hip-joint endoprothesis comprises an acetabulum cup 6, a non-metallic shell member 1 and a retaining nut 10. The shell member defines therewithin a volume 8 which is greater than hemispherical and less than spherical, having an opening around which the wall of the shell member is formed with radial slots 9. The nut 10 serves to hold the head portion of a femur shank in the volume 8 and simultaneously lock the shell member 1 in the acetabulum cup 6. In accordance with requirements, the shell member may be used with an acetabulum cup which is of self-anchoring type or to be cemented in the natural acetabulum and with a shank which is self-anchoring or to be cemented in the medullary canal of the thigh. <IMAGE>

    However, non-collapsible collapsible structures create the possibility for spontaneous dislocation of the joint with relatively low non-functional loads, and closed non-collapsible constructions with high functional forces can cause fractures of the femoral or pelvic bone, while the natural joint with such maximal non-separable constructions is difficult to implant. what is the reason for the cut-off. Most of the three-artery mass. A disadvantage of the hip joints with a conical body is often the practice of loosening the body in the medullary canal, which leads to rotation and instability of the joint, and from there to strong bolts that absolutely restrict any movement of the lower limb. The disadvantages of some hip joints are their lack of variability during implantation, depending on the specific clinical indications and the need to change the entire endoprosthesis or entire parts of it through secondary bone fracture during reoperation due to failures during the postoperative period. So, for example, when using an endoprosthesis with a metal sphere and a non-metallic capsule, a plastic capsule is often erased, which leads to the need to change the entire acetabular capsule during reoperation and, as a result, to a secondary injury to the pelvic bone. The purpose of the invention is to create a hip joint design that allows the selection of individual parts, components of its set (femoral bodies and acetabular caps) depending on the specific clinical parameters for gluing or mechanical attachment to the braids during surgery, as well as easy and non-traumatic change of individual and worn or loosened parts with possible reoperation. By providing a stable fixation to the appropriate bones, the structure should also provide a physiological closure of the articular connection that is consistent with the antiviral ability of the natural joint, and must be collapsible for easy manipulation during the operation, so as not to create
    to increase the internal pressure in the modular channel during operation.

    This goal is achieved by the fact that in a collapsible hip joint consisting of two acetabular capsules (one metallic, with a serrated outer surface. For mechanical attachment, and another metallic or plastic, suitable for bonding with bone cement), and two femoral bodies (one rectangular and jagged in its upper part for metallic attachment, and the other is flat and has smooth walls for bonding with cement), which are interconnected in the desired combination by incorporating the femoral sphere in a nonmetallic nest and tightening the nut, the nonmetallic nest is packed nonseparably into the corresponding box of the acetabular capsule, covers three quarters of the sphere and has radial slots in its outer conically shaped periphery and on the smooth walls of the femoral body there are longitudinal channels of oval cross section. The advantages of the proposed hip joint are that the collapsible socket, in which the metal sphere rotates, is nonmetallic and, providing minimal friction and the absence of a bimetallic corrosive effect, easily and non-injuringly replaceable during wear, and the radial slots along the periphery make it possible to grip three quarters the rotating sphere when assembling the joint, and after installing the fixing nut, they ensure the closure of the joint with a force that corresponds to the physiological anti-withdrawal ability and the natural joint, thereby preventing accidental breaking out of the acetabular capsule from the gas bone or fracture of the hip bone. Disassembly of both parts of the joint. (Acetabular capsule with a non-metallic nest and femoral body) allow for easy manipulation during re-implantation, and the longitudinal oval channels on the smooth walls of the femoral body prevent an increase in pressure in the modular canal during the stuffing of the body in the femur. 598 In addition, the jointed joint, due to the presence of mechanically fixed and glued bone cement components that are interconnected by a single non-metallic nest / and nut, allows the operator to select the most suitable during implantation or reoperation. a method for attachment according to specific clinical indications. The drawing is schematic; components of the hip joint. The replaceable nonmetallic socket 1, into which the sphere 2 of body 3 enters and rotates, has a neck k, by means of which it collapses, without admitting rotation, into the hole 5 of the acetabular capsule 6. To prevent dislocation of the joint, the periphery 7 of the spherical hole 8 of the socket 1 is lowered under the equator of the sphere
    [2]
    2. On the periphery 7, radial holes 9i are made, which make it possible with light pressure on the opening 8 of sphere 2 to enter rHe 1. In connection with attaching nest 1 to orifice 5 of the capsule, the purpose of physiological closure of sphere 2 in nest 1 is to orifice 5 of the capsule when fastening nut 10 is screwed in, which with its internal conical hole 11 presses the slotted conical periphery 7 of the socket 1 and makes it impossible for the joint to spontaneously dislocate. Clenching is concomitant with the requirements of the freedom of rotation of the sphere and with the possibility of forced latching with forces that result in dislocation of the normal natural joint. This prevents fracture of the femur bone or breaking out the acetabular capsule. The acetabular capsule 6 has an inner bed 12 for a replaceable non-metallic socket 1 and an opening 5 for stuffing, its neck, as well as a slit 13 for tightening the fastening nut 10. On the outer side, an acetabular capsule 6m has specially decorated teeth AND serving to jam in the pretreated nest of naturally acetabulum. The outer side of the adhesive acetabular capsule 6c (metal or plastic) is framed by channels 15 to ensure stable fixation to the bone cement. 9 The femoral bodies are provided with a pad 16, which is elongated in its anterior part, which lies on the cortical contour at the base of the femoral cervix, i.e., the femoral body sustainably weights the body without plunging into the soft spongy bone tissue. The 3 m self-locking body is wide and rectangular in order to prevent rotation in relation to the bone of the thigh. In the upper part, the body is 3m indented with teeth 17, between which round holes 18 are drilled. The teeth serve to further expand the holes in the bone of the thigh previously drilled with special files to separate the bone chips that fill the circular holes and the space between the teeth and bones. As a result of the ossification of these shavings in the postoperative period, the body is firmly fixed to the bone of the thigh. In the lower part, the rectangular body is smooth; longitudinal oval channels (9 m) are cut in from four sides, which prevent the creation of increased pressure in the modular channel when the body is stuffed into the bone. Gluing the 3 m self-fixing body with bone cement makes it possible to fill holes in the femur bone with the necessary amount of cement.The cross-section of the body has the shape of a flat hexagon with rounded middle ribs and longitudinal oval channels 19c on the outer edges, it has smooth walls and an oval The 19c channels have the same functions as the 19m channels. The hip joint is implanted as follows: Depending on the specific clinical indications, the appropriate acetabular capsule and the femoral body are selected for self-consolidation or gluing. mechanically fixed joint, glued acetabulum and mechanically fixed body or mechanically fixed acetabulum and glued body. Both parts of the joint are fixed, each separately, to the previously prepared bone of the hip and the pelvic bone. After this, the sphere of the body is placed in the spherical hole of the non-metallic socket and is closed in it by means of a fixing nut. When reproducing an operation, the joint of unscrewing the nut and the compromised part is replaced with a new one without breaking out the stably fixed parts. Then the joint closes again. The clinical results after implantation of the proposed hip joint are quite satisfactory in terms of functionality and dynamic stability. Claim 1. Hip joint consisting of two acetabular capsules - one self-fixing 6 m and the second glued by bone cement for 6 s and two femoral bodies - one self-locking 3 m and the second glued by bone cement 3c, which are connected to each other depending on the clinical need in the four 98 98 combinations by means of the metal socket 1 and the fastening nut 10, which is indicated by the fact that the nonmetallic socket 1 is placed in the bed 12 of the acetabular capsule 6 and is disassembled with it by its neck k and screwing the capsule 6 into the cutting 13 of the fastening nut 10.1 and also has, on its outer conically shaped periphery 7, radial slots 9, by means of which forms three-quarters of the spherical opening 8, from its side the fastening nut 10 has an internal tapered opening 11, coinciding with the conical shape of the periphery 7 of the nest 1, and on the smooth walls of the femoral body 3 are located longitudinal oval channels 19. It is recognized as an invention according to the results of the examination carried out by the department of inventions the People’s Republic of Bulgaria,
