Description

DETAILED DESCRIPTION OF THE INVENTION

SUMMARY OF THE INVENTION It is a primary object of the present invention to provide an external aid for the treatment of a fracture at the tip of the radius, thereby effecting the fracture at the tip of the radius without requiring a puncture of the lower radius of the elbow joint. Is to be able to be treated effectively. More specifically, the patent of the present invention protects the functional and structural features of special external aids that can be used as fixation aids during the above-described fracture procedures. A major advantage of the aid of the present invention is that when the aid is worn, the postoperative patient's wrist can move well for both bending and extension movements, as well as pronosupination. That is. Thus, the patient can perform operations such as pouring water from the container and drinking water from the glass, and can perform such operations gently. This is faster than conventional treatments for similar purposes (plasters, joint bridging aids, etc.), which require long-term absolute fixation of the affected area. The possibilities are clear. The features of the assistive device of the present invention provide the patient with greater comfort throughout the health treatment and reduce the risk of reflex sympathetic nervous system phenomena and osteoporosis. In essence, the invention relates to a method having a length of 70 mm,
Reference is made to a flat, one-piece aid having a width of 10 mm, a thickness of 5 mm, and a planar head articulated to the aid by means of a lateral screw. The head can be rotated about the lateral screw and can be fixed at a position chosen by the physician. Novelty is noted in the head and body with an opening through which a vertical pin that positions the fractured bone in the correct location. Another feature of the present invention is that the pin and the auxiliary tool used form a triangle having excellent stability and safety. For this effect, the opening of the connected head is inclined 45 degrees with respect to the axis of the aid, and the body preferably has three openings, two of which are shafts. Perpendicular to
The remaining openings have a relative slope to allow for the use of additional pins to support the bone fragments that remain unsecured by others. The openings through which the pins pass face a vertical conduit provided with a corresponding headless clamping screw. The screw exerts a pressure on the pin, thus providing a removable friction adjustment retention feature. Therefore, the following work must be performed to allow the patient to wear the aid of the present invention. First, the patient is placed in a supine position and anesthetized. Thereafter, a "Zockowlosky" device pulls the hand and a counter traction is applied from the elbow to eliminate the burden using a 5 kg weight. This makes it possible to perform manual reduction. The first pin is then pierced, for which purpose it is convenient to use an image intensifier or an Rx (resolver transmitter) control (which is simpler than the image intensifier). is there. In this way, the first pin is inserted at a position at an angle of 45 degrees with respect to the radial pedicle. This pin
It penetrates the fractured part inside and penetrates further into the internal cortex on the proximal side of the radius. After the first pin has been pierced, the assisting device of the present invention is attached and mounted by using the opening at the tip and penetrating the pin through this opening. At this time, in order to prevent pressure ulcers, the assisting device is kept 1 cm away from the user's skin. Thereafter, the second pin is disposed so as to penetrate the most proximal opening of the auxiliary tool body. This second pin acts as a guide because it is oriented perpendicular to the plate and radius. After the above steps have been completed, the remaining passage openings are used as guides for the placement of the remaining pins, and finally the aid is installed. This is very simple. If there are front or rear debris or "Die Punch" debris, the debris is reduced and then the remaining opening in the aid body is used to place the sixth pin. You. The stable mounting of the aid according to the invention is achieved by adjusting all the screws facing the opening through which the pin passes and by the lateral screws acting as axes connecting the head of the aid. Then, Rx control is performed. The aid described above is particularly suitable for the treatment of intra-articular and non-displaced intra-articular fractures. Due to the above-mentioned feature that the head of the assisting device is articulated with the assisting device main body and the head can be rotated until it takes a selected position before adjustment and wearing, the angle of the pin is directed toward the radius. It can be adjusted to any different angle, either direction or away from the radius. When the aid is finally installed, the structure forms a triangle with the pins, and this structure is the most permissible from a physical and mechanical point of view for the various mechanical requirements of the aid. It is a robust structure with high degree. In order to explain the advantages mentioned briefly above and many other advantages conceivable to the user and those skilled in the art, and to facilitate an understanding of the structural, essential and functional features of the external aid of the present invention, In the following, a preferred embodiment is illustrated schematically, ignoring specific dimensions, based on the accompanying drawings. Therefore, the scope of the present invention should be construed as the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS In accordance with the example chosen for the present description of the aid of the present invention, identical parts of the assembly are given the same numbers throughout the figures. As can be understood from the drawings, the external aid of the present invention is a hard piece having a main body 1 and a head 2 articulated thereto. Due to the articulation, the projection 3 of the head 2 is fastened in a hole 4 formed in the base end of the body. The projection 3 has a lateral opening on which the mounting screw 5 acts. Therefore,
The head 2 can be rotated relative to the body 1 (as shown in FIG. 3) until a pin passing through at an angle of 45 degrees is in a suitable position with respect to the longitudinal axis of the body 1. it can.
The mentioned head 2 has, in its body, passage openings 6, 7 and 8 inclined with respect to the longitudinal and transverse axes, and the screw holes 9, 1 on which the pressure mounting screws 12, 13 and 14 act.
0, 11 along the horizontal plane. On the other hand, said body 1 also has passage openings 15 and 16 corresponding to the screw openings 17 and 18 to which the pressure mounting screws 19 and 20 are fastened, respectively. From observation of these figures,
The openings 6, 7 and 8 of the main body 2 are designed so that the pins 21, 22 and 23 for fixing the fractured portion of the radius 24 penetrate and hold them, and the openings 15, 16 are It is designed to penetrate and hold pins 25, 26 used to stably secure the assembly in the required state. With reference to FIGS. 4 and 5, it can be clearly seen how the aid of the invention is used in the treatment for this type of fracture. A triangular structure is formed in which the pin forms a right triangle defining one of the hypotenuse and the side. Therefore, a non-deformable structure is formed, which has good stability and resistance and prevents the occurrence of undesired relative movement in the fracture. As can be seen from FIG. 5, the present invention contemplates the use of additional pins 27 as needed for further bone fragment formation. This pin is fixedly held on the body 1 without affecting the normal operation of the above-mentioned structure. As mentioned in the figures, the mounting bolts used belong to the type in which they are completely accommodated in the openings or screw holes in which they act, thereby resulting in external friction. The problem of over-adjustment or de-adjustment is prevented.
