Abstract

The invention concerns an unguided endoprosthesis for small limbs, in particular for toe and finger joints. The endoprosthesis can be used to replace, in a single operation, one side or the whole of a damaged joint. Depending on the degree of damage, only part of the joint may be replaced or the whole of it. The patient can therefore be treated rapidly and usually without having to be admitted to hospital as an in-patient. The joint surface (1) of the endoprosthesis proposed is circular or rectangular in shape with rounded edges and preferably with a conical central hole (3). A centering pin (4) passes through the hole and into the bone (8) behind it. The joint surface (1) and the centering pin (4) are preferably made of a non-allergenic high-strength ceramic material.

Description

Unguided endoprosthesis for small joints

The invention relates to a non-guided endoprosthesis for small joints, especially the joints of the toes and the joints of the fingers.

Endoprosthesis for small joints have been known for years for the replacement of destroyed joints. These prostheses are mostly made for humans compatible metals and are surgically inserted in place of the destroyed joint.

In EP-A1-0 455 929 a joint prosthesis is proposed particularly for a finger joint, comprising a one bearing surface having bearing body in the form of a thin-walled shell element of high-strength metallic materials, at the back of a to be embedded in the bone shaft is integrally formed.

Similarly, the EP-A-0420794 proposes a

Finger joint prosthesis before consisting of two successive sliding prostheses halves which are anchored in each case in the associated part of the hinge bone ends. The prosthesis halves are made of a sintered structure of hydroxyl apatite. Where this material is not suitable for highly stressed joints, since it does not provide the required high strength properties.

In the EP-A-0 396 519. special anchoring element will be described for anchoring a prosthesis in the bone ends. Using the invention, the joint prosthesis is possible firmly and deeply rooted in the adjacent bone. A guide bushing ensures a sufficient centering. This anchoring member is preferably made of titanium or is coated with titanium. It may have additional surface finish to facilitate securing the bone and improve grip.

All prostheses are made of metal. However, the use of metal has major disadvantages for the replacement of joints. Particular mention here the poor lubricity, which leads to high stress on the joints, especially if only one side of the joint was replaced. Here the bone experiences a high abrasion from the metal part. As another high allergenic burden of the metal or metal alloys may be cited.

Further disadvantages arise from the extensive resections of the replaced bone part. each

Fixing in the bone necessarily requires a large bone length for good durability is achieved. The end joints of the fingers are consequently not be produced again with such prostheses.

Moreover, the stress in the members of the toes and fingers are very different. Thus, the joints of the toes are more contaminated than the joints of the fingers. Guided joints, such so that are anchored in the adjacent bones are less durable than joints that are not performed. It is therefore increasingly trying in particular to replace the joints of the toes by not guided endoprosthesis.

In EP-A-0314593, a non-guided joint replacement is suggested. For the replacement of the joint in a first operation, a joint surface of metal, which has the form of a joint socket, inserted between the bones between which the joint is to be replaced, and held by a screwed-in from the toe forth mandrel. In a second operation, the mandrel is pulled and the joint surface is removed again in a third operation, when the formation of the joint is completed. This in France for a long time practiced method should restore the natural joint again. The disadvantage was mainly the phenomenon that the joint surface was frequently postponed because of the lack of centering, when the mandrel was pulled, and thus the healing success was not achieved. In addition to high loads, particularly the first and third operation the patient was over a longer period, but at least during the time in which the mandrel was needed, unable to walk.

The object of the invention is therefore to provide an endoprosthesis for small joints, is not performed, and the replaced by a single operation, the destroyed joint.

Another object of the invention is to cure the patient as quickly as possible and without hospitalization.

The solution of these objects is solved by a stent according to the main claim.

The joint surface, which is to replace at least a missing hinge part is locked with a centering pin in the bone. For this purpose, has the joint surface, which has a circular or rectangular shape with rounded edges, preferably a conical center hole. Through this the centering pin in the underlying is

Bone introduced. The joint surface and the centering pin are preferably made of a non-allergenic high-strength ceramic material such as a ceramic based on zirconium oxide TOSOH CORPORATION, Japan, but they can also consist of plastics, metals or metal alloys which have the required non-allergenic properties have. It is not necessary that in a joint replacement, the joint surface and the centering pin in each case consist of the same materials.

In order to secure the inserted implant against rotation, which can occur in particular at the joints of the fingers, it is also possible to form the flat portion on the opposite side of the joint surface wedge-shaped. The bone to which the endoprosthesis is to be adapted, then it must have a corresponding wedge-shaped recess into which the wedge-shaped part of the endoprosthesis is fitted.

The implantation of these prostheses consists of the following steps: In a first step by the

resected articulation surface to be replaced bone part, in a second step, the joint surface is adjusted to the bone, in a third step the articular surface with a centering pin which is pushed through the center hole of the joint surface into the underlying bone, centered. Thereafter, the wound is closed.

If a complete joint are implanted, the steps 1 to 3 at the opposite joint part to be repeated and then the wound is closed.

Thus, it is now possible to restore the distal interphalangeal joints of the fingers and toes completely by an endoprosthesis. The replacement of the defective joint is effected in a single operation in which either be replaced only one joint portion, or both. The stent remains in the body. The advantages of the proposed endoprosthesis exist primarily in the low exposure of the patient. The bone must be resected only to a very small extent. The centering pin has no object of the anchoring, it locks only the joint surface against lateral slippage until it is surrounded by the newly formed bone tissue. The penetration depth of the centering pin in the adjacent bone is therefore very low. Preferably, the endoprosthesis from a non-allergenic ceramic. This has significantly better properties in terms of compatibility with human, as the metal parts used to date.

The invention allows a cost-effective recovery of destroyed joints both in terms of the implant and in terms of operation and the post-treatment of the operated patients.

The invention will below through

Embodiments will be explained, reference being made to the accompanying drawings.

Invention;

Fig. 2 is a unilateral replacement of Fingerendgelenkes of the third finger;

Fig. 3 is a unilateral replacement of a joint of the first digit;

Fig. 4 shows the replacement of a complete joint of the first

Toe. FIGS. 5a to 5c show examples of endoprostheses according to the invention with a wedge-shaped

Fitting into finger bones.

Like parts are designated in the drawings with the same reference numbers. In FIGS. la to lc and FIGS. le to lg are some forms of joint surfaces 1 for small joints as views from above and sectional views taken along lines II through VI-VI shown. Fig. La shows a circular joint surface 1 for the replacement of the joint of the toe to the center hole 3. This center hole 3 preferably has a smaller diameter than on the hinge side on the bone lying on page 8. The circular surface has here a concave curvature 5 for the replacement of a proximal joint part. The voltage applied to the bone 8 side has a flat second

In Fig. Lb an articulation surface L is shown with a convex curvature 5 for replacement of the distal joint part, complementing the joint surface 1 of FIG. 1 to form a complete joint for a toe joint.

In Fig. Lc an articular surface 1 is shown for replacement of a finger joint. According to the anatomy of the finger joint, the articular surface 1 has a rectangular shape with rounded edges.

In FIGS. le and lf is also equipped with a concave (5) and a convex curvature (6) the articular surface of the endoprosthesis for the last finger joint. The concave curvature (5) is associated with the proximal joint part as in the other endoprostheses and the convex bulge (6), the distal joint part.

Fig. 1g also constitutes an endoprosthesis for the last finger joint. With this embodiment, the entire last bone member can be replaced. This form is advantageous particularly when the end link is so severely damaged that it can provide the endoprosthesis no conditioning. In Fig. Ld some forms of the centering pins 4 are shown. Preferably the centering pin 4 has a conical shape and may have certain to increase the surface of the shank per se known designs. In addition, the cross-section of the centering pin 4 can be shaped differently. Furthermore, a rounded head 9 may be formed, which offers additional advantages for both the insertion and centering. The use of centering pins 4, which have a rounded head 9, is especially advantageous in the replacement of finger joints.

Fig. 2 shows a schematic representation of a unilateral replacement of a finger joint with the help of the in Figure lc. Joint surface shown 1. It can be clearly seen that the centering pin 4 penetrates only slightly into the adjacent bone. 8 It is also seen that the bone has been resected 8 very low. Thus it is now possible to restore the end joint of a finger surgically. Since the articular surface 1 remains in ceramic after the healing process in the finger, there are no other loads. The newly formed bone tissue includes the highly compatible ceramic body and returns it by the required support.

Fig. 3 shows an equivalent of the proximal joint part of an articulation of the first toe by means of the joint surface shown in Fig. La 1. In accordance with anatomy of the joint has the joint surface 1 a concave dome 5 and is locked to the corresponding bone side with the help of the centering pin. 4 the small depth of penetration of the centering pin 4 in the adjacent bone is also visible in this embodiment. The concave curvature 5 runs it against the healthy joint part. Experience shows that not only the functioning of the joint is restored, but also the natural joint side is stabilized.

Fig. 4 shows the use of a complete hinge in the first toe. It is both a joint surface 1 of FIG. La and a joint surface 1 of FIG. Lb used in place of the destroyed joint.

Figs. 5a to 5c show endoprostheses according to the invention, with wedge-shaped Insertions in the bone 8 of the distal interphalangeal joints of the fingers. Fig. 5a shows the replacement of the proximal joint part of the end member, wherein the implant 1, 5, the concave curvature of the implant 1, the center hole 3, 4 denote the center pin 7 and the wedge-shaped recess. Fig. 5b shows the replacement of it. Distal portion of the distal interphalangeal joint, and Fig. 5c shows the replacement of the entire joint The wedge is located in each case perpendicularly to the direction of movement of the joint. This embodiment of the invention is particularly advantageous in the replacement of finger joints, the finger joints because when the risk of twist is relatively large.

The exemplary embodiments are illustrative only. Similarly, the joints of the l, 2, 4 and 5 as well as the finger 2. supplied to 5th toes with the corresponding endoprostheses can.

After resection of the destroyed joint parts 2, the flattening of the articular surface 1 or the wedge-shaped opposite side of the articular surface is adapted to the bone 8 and centered with a center pin 4 at the underlying bone 8 at the operation. As already stated, this does not serve centering 4 of the fixture. done the required fixation of the implant solely by the healing process in which the newly formed bone tissue surrounds the endoprosthesis. The operation is terminated after closure of the wound.

These examples should be clear that these are small implants that allow even the smallest joints of the human hand and toes can be recovered economically. The operation for inserting the endoprosthesis can be done on an outpatient basis under certain conditions.

Although the present invention has been described and illustrated in detail, it is clearly indicated that the examples are only intended to illustrate and not as a limitation. The scope of the present invention being limited only by the claims.
