The sleeve 84 of the collar 80 is preferably with multiple holes 86 are formed through which bone tissue can grow in order to hold the collar 80 in place the correct "division on the thigh bone to support.

As mentioned above, the inserts 30 are preferably releasably connected to the head 13. this has the advantage that the inserts can be replaced when they are in the after a certain period of use The patient's body is worn or otherwise damaged.

In a preferred embodiment, a groove 88 and in the head 13 of the acetabular prosthesis is a groove Insert or each of the inserts 30 has a groove 90 formed. Given the dimensions of the head 13 and the

309830/0478

Inserts 30 are the grooves formed in these parts so that the inserts are fixed and attached attack the inner wall of the head 13 when the grooves 90 and 88 correspond to one another. In the grooves 90 and 88, a flexible ring 92 is normally disposed which supports the insert or inserts 30 in the head 13 of FIG Acetabular prosthesis.

In order to facilitate the insertion and removal of the flexible ring 92, the head 13 is the acetabular. The prosthesis is formed with an access slot 94 that communicates with the groove 88, and at least one insert 30 is formed with an access channel 96 that communicates with the groove 90. The access slot 94 and the access channel .96 are readily available and allow insertion of the ring into the grooves and, when the ^ ± n sets 30 are to be removed, a removal of the ring.

The access slot 94 and the access channel 96 are preferably formed so that each of them is opposed to an angle of about 25, its apex is in the center of the hip ball 28. With this dimensioning there is enough space for easy insertion and removing the ring 92 present. The grooves 88 and 90 are also sized so that the inserted ring 92 primarily on the outer surface 98 of the groove 88 and engages the inner surface 100 of the groove 90 and therefore the inserts 30 e.g. Surfaces 102 and 104 fit snugly against head 13 the acetabular prosthesis pushes.

It is again the head 13 with the anger 88 and are the stakes formed with grooves 90. When the head and inserts are assembled, the grooves 88 and 88 correspond with each other and a ring 92 is arranged in the grooves, which the inserts 90 in the head 13 of the acetabular prosthesis holds on. This ring need not have an eyelet, but is preferably flexible so that it comes out of the groove 90 in the groove 88 springs when the inserts 30 come into the correct position in the head 13. One can also according to Fig. 6 first spread the ring into the groove 88 so that it springs into the grooves 90 when the groove 88 and the grooves 90 correspond to one another.

When using an artificial hip joint, it is extremely important that the artificial hip joint with the

309830/0478

Thigh bone is rigidly connected and cannot rotate in relation to the thigh bone. For laying the plague of the artificial hip joint against the thighbone means are provided according to the invention, which with the Femoral head prosthesis are related in that they rotate the femoral head prosthesis to prevent against the femur.

In the embodiment shown in Figure 7, the anti-rotation means comprises a rib 110 integral with the pin 24 and extending therefrom which engages a slot (not shown) cut in the femur by the surgeon. The -tip 10 extends · preferably only along a small part of the pin 24. The engagement of the rib in the slot prevents rotation of the pin 24 in the cavity of the femur containing the bone marrow.

Another embodiment of the one in the artificial one Rotation-preventing means provided in the hip joint is shown in FIGS. 8 and 9. After that, insist the rotation-preventing means of a plurality of cutting edges 118 which are integral with the pin 24, are extend in the longitudinal direction and cut into the femur so that they rotate the femoral head prosthesis to prevent against the femur.

Another embodiment of the anti-rotation agents is disclosed in Pig. 10 shown. After that extends from the end of the pin 24 which extends into the bone marrow containing cavity 114 of the femur 116 is driven, a sharp spade-shaped part 120 beyond a rubbed part 122, which

309830/0478

located in the cavity containing the bone marrow. According to FIG. IT, the spade-shaped part can be made in one piece with Teeth 124 may be formed that engage the femur and allow rotation of the pin relative to it prevent the thighbone.

Further embodiments of the invention anti-rotation means provided are shown in Figures 12-17. According to FIG. 12, the collar is 60 connected to a wedge 126 extending from the collar 60 extends obliquely outward and downward and into a cutout or slot; 112 engages the femur. When using the collar SO this can be formed according to FIG. 13 with a keyway, which the wedge 126 records. This engagement helps prevent rotation of the pin 24 relative to the femur at.

In a further embodiment of the anti-rotation 14, the collar 60 has an opening 130 in which a square head pin 132 or a differently shaped pin with a head for engaging the side walls of the slot 112 in the femur is arranged. This pin extends obliquely outward and downward from the collar 60 and engages slot 112 in the femur, so that rotation of the pin 24 in the femur is prevented.

A rotation of the pin 24 in the femur can also be achieved by the in ^x ig. 15 means shown can be prevented. In this arrangement, the collar 60 is provided with a cavity 134 and the pin 24 is provided with a recess 136 . In the cavity 134 of the collar, one end of a bolt 138 is arranged, which extends along the

309830/0478

Pin 24 extends and see the second end in the Recess 136 of the pin is located. A slit 112 is cut again in the thigh bone, in the the bolt 138 engages so that the pin 24 is in the thighbone cannot rotate.

Another embodiment of the invention antirotation agent contemplated is disclosed in Pig. 16 shown. Thereafter is integral with the pen, Immediately below the collar 60, a link 131 is formed which has several corners 133. Preferably the limb is 131 square in cross section and the corners 133 are substantially parallel to the axis of the pin 24.

The dimensions of the cross-section of the square 131 can be chosen so that the side length of the square is equal to the diameter of the pin 24 in the region of the collar 60. The sides of the square 131 can but also be longer than the diameter of the pin 24

When inserting the artificial hip joint according to the invention, it can often be desirable to completely avoid injuring the larger rolling hill. For this reason, it can be expedient to design the collar 60 with a lateral flattening 61 according to FIGS. 16 and 17, which can be placed against the larger rolling hill 63. This smooth abutment of the lateral flattening 61 of the collar 60 on the larger rolling hill of course also prevents the femoral head prosthesis from rotating with respect to the femur. This rotation-preventing effect of the lateral flattening 61 is further supported by the fact that the flat 61 is preferably arranged parallel to the axis of the pin. In the context of the invention, of course, a prosthesis of the type described with the lateral

309830/0478

Flattening 61, but without the member 131, use, or also a prosthesis of the type described with the limb 131, but without the lateral flattening 61 or the collar 60.

18 shows an embodiment of the invention provided means for preventing relative movement between the inserts 30 and the head 13 of Acetabular prosthesis. Rotation between the inserts 30 and the head 13 of the acetabular prosthesis must be prevented because a relative movement only takes place between the inserts 30 and the hip ball 28 in the hip joint target. The hip ball and the inserts are specially designed and made for this purpose. Made of materials, which can cope with a frictional movement between these parts * In contrast, the head 13 and the inserts 30 are the Acetabular prosthesis not designed according to this requirement, so that a relative movement between the Head 13 and the inserts 30 must be avoided. It is also useful to keep the access slot 94 and the access channel 96 in alignment with one another so that the flexible ring-92 can be inserted and removed at any time. If the access slot 94 and the access channel 96 can move relative to one another, one can Only insert or remove the flexible ring when the access slot 94 and the access channel 96 are back together cursing.

In one embodiment of the invention, at least one of the inserts 30 with a projection HO and the head 13 of the acetabular prosthesis with a recess 142 formed which receives the projection HO so that a relative movement between the inserts 30 and the head 13 is prevented. The recess 142 can be arranged in such a way that that, similar to the hat extension 108 in the embodiment according to FIGS. 2-4, a tool for detecting of the flexible ring 92 can accommodate.

309830/0478

It has already been explained above that it has often proven desirable in the event of wear or a malfunction of the artificial Hip joint repair or replace the bearing surfaces of the joint if the patient has been using the joint for a while used. For this reason, the invention enables the inserts 30 to be easily removed the artificial hip joint, open the bearing surfaces of the The joint needs to be repaired or replaced after the patient has used the joint for a period of time, it may be useful to replace the hip ball 28 as well. This is illustrated by that shown in Figures 19 and 20 Arrangement allows.

According to FIG. 19, the hip ball 28 is detachably arranged on the curved neck 26 and is formed with a recess 144. The neck 26 is also formed with a recess 146 which is aligned with the recess 144 in the hip ball, by a retaining pin 148 which passes through the recesses 144 and 146, the hip ball is kept 28 on the H ls _a 26th The retaining pin 148 is frictionally seated in the recesses 144 and 146 so that the hip ball 28 is fixed on the neck 26 during use of the artificial hip joint. If the hip ball 28 is to be removed from the neck, the pin 148 can be knocked out of the recesses 144 and 146 with the hammer so that the hip ball can easily be repaired or replaced.

Another embodiment of a detachable hip ball 28 is shown in FIG. 20 shown. After that, the H; j1 3 26 a tapered free end portion 150. The hip ball 28 i3t formed with a tapered opening 152 which snugly fits the tapered end portion 150 of the neck can accommodate. The hip ball can therefore be

309830/0478

press on the tapered end portion 150 of the neck 26 set on this. The hip ball 28 is also with a Hole 154 is formed, which opens on the outer surface of the hip ball and with the tapered opening 152 in the hip ball is in communication so that the hip ball can easily be removed from the neck with the aid of conventional tools not shown can be solved.

2t shows a further embodiment of the artificial hip joint, in particular the insert, In This embodiment is the acetabular prosthesis 10 with Grooves 160 formed, which are provided with G-ewindegänge. The one-piece insert 162 is integral with a thread-bearing, annular part 164 formed, which are screwed into the grooves 160 of the acetabular prosthesis can. The insert 162 is also formed in the area of the threaded ring 164 with notches 166, which screw in of the ring in the grooves 160 allow.

As in the previously described embodiments, the pan surface formed by the inserts is larger than a hemisphere, so that the hip ball is held in the socket and a postoperative dislocation is prevented.

The insert shown in Fig. 21 is preferably made of plastic such as very high density polyethylene Molecular weight. The plastic is first heated so that it expands, whereupon the hip ball 28 into the pan 12 is pushed in. The insert is then allowed to cool so that it contracts around the hip ball. Of the The hip ball containing the insert is then threaded with its ring 164 screwed into the grooves 160 of the acetabular prosthesis until the insert in the acetabular prosthesis stuck.

309830/0478

Pig. 22 shows a metal, preferably two-part insert 162. This consists preferably made of a cobalt alloy, e.g. ASTM F75-67.

When assembling the embodiment according to FIG. 22, first of all the two parts of the insert placed around the hip ball 28. The parts of the insert are designed so that the surfaces 168 are snugly against one another. After that, the arrangement consisting of the hip ball and the two parts of the mission is made with the crew in-ring 164 screwed into the grooves 160 of the acetabular prosthesis 10.

The embodiments shown in FIGS. 21 and 22 are particularly beneficial. With a one-piece use, the hip joint is particularly robust and grown strong forces and tensions. As a result of the formation of grooves provided with G-thread turns in the The acetabular prosthesis and the threaded ring that is integral with the insert can easily be removed from the acetabular prosthesis can be removed if the insert is to be renewed or repaired. This can of course also after implantation of the hip joint.

The invention thus creates a very versatile and durable hip joint that is inexpensive to manufacture can be and its storage areas can be easily replaced if necessary or is appropriate. The artificial hip joint according to the invention also has novel rotation-preventing means, which cooperate with the thigh bone in such a way that the artificial hip joint opposite the thigh bone cannot be rotated. This prevention of rotation is for satisfactory use of the hip joint very important and allows the patient to follow
