Definitions
- the invention relates to an endoprosthesis for anchoring in the femoral neck of the femur.
- Lamellar nail used for stabilization in the femoral neck (Thomson JEM (1952) A prosthesis for the femoral head. The Journal of bone and Joint surgery 34- A No 1: 175-182)
- DE 837 294 also describes a femoral neck prosthesis with smaller lamellae and spikes on the osteotomy surface.
- a disadvantage of the fairly widespread pressure disc endoprosthesis (DE 2724234 C2) is that a so-called “tab” must be attached below the trochanter major in order to tension the so-called “pressure disc” lying on the resection plane. Since the support surface of the thrust washer is not suitable for introducing significant rotation and bending loads around the longitudinal axis of the endoprosthesis into the bone, the bracing is in phase the bone healing in the pressure disc prosthesis is essential. However, the "tab” required for this means not only an additional surgical measure, but often also pain for the patient in the area of the tab located directly under the muscles.
- Another disadvantage is the high loosening rate of the pressure disc endoprostheses varus misalignments) there is an overload of the bone bearing on the calcar femoris and the endoprosthesis migrates to a further varus position and ultimately a loosening of the implant.
- the reason for the overloading of the bone bearing on the calcar femoris is likely to be the small support surface mentioned above lack of rotation and bending stability around the longitudinal axis of the pressure disc endoprosthesis.
- a disadvantage of the systems described in DE 3839704 A1 and DE 19842554 A1 is the complicated intraoperative anchoring of the endoprostheses and the unclear blood supply to the remaining bone after the thread has been cut, since the bone is severely cut open from the inside and damaged accordingly.
- the fixation in the bone should, in particular, be easy to handle intraoperatively.
- At least two ribs - in a preferred embodiment of the invention four ribs (1) circularly - are arranged around the longitudinal axis of the endoprosthesis.
- the outer boundary of the ribs is adapted to the oval cross-section and possibly also the proximal expansion of the femoral neck. In the distal direction, the ribs can also lose depth or leak completely.
- the cross-section of the endoprosthesis increases in the proximal area and forms a wide support collar (2) interrupted by the ribs for the proximal load introduction into the femur.
- the angle (6) at the level of the osteotomy plane in the sectional plane (4) between the support collar and the osteotomy plane through the longitudinal axis of the endoprosthesis is greater than 40 ° , It is also advantageous if the support collar formed in this way opens into an additional end plate (3). It is advantageous if the depth of each rib (7) at least at one point is> 10% of the endoprosthesis diameter (5) measured at the osteotomy level. With a typical femoral neck diameter at this point of 30 mm, the depth of each rib should be at least 3 mm at one point.
- the proximal area of the endoprosthesis has a special microstructuring or coating which Bone growth in this area is favored and prevented in the distal area. This leads to increased load introduction in the proximal area and axial sliding of the endoprosthesis in the distal area, so that the effect of stress shielding with the dreaded bone atrophy in the proximal area is prevented.
- the coated or microstructured proximal area should not extend deeper than 40 mm into the neck of the femur.
- the endoprosthesis In order to support this effect of the proximal load introduction, it can make sense in a preferred embodiment of the endoprosthesis to provide a recess (10) at the lateral end (ie the distal end of the prosthesis), for example in the sense of a hole, so that there is no growth here of the bone and therefore no load transfer can take place.
- Advantageous materials for the endoprosthesis are titanium or the titanium alloys intended for endoprostheses, in particular TiAIV, TiAIFe or TiAINi alloys.
- Other metals intended for endoprostheses, e.g. Co-based are also suitable.
- distal fixation can also be used to brace the endoprosthesis. It is particularly advantageous if this fixation is carried out, for example, in the sense of screw anchoring from proximal to distal (in the sense of an "anterograde" tensioning of the endoprosthesis in the bone, see arrow (9)), so that the femur is at the trochanter major area does not have to be freed from the lateral to accommodate a tab or the like, in a preferred embodiment of the invention a screw (8) is screwed from proximal to distal into the femoral neck, cancellous bone (15) (cf. also FIG. 4).
- This screw can also perforate the lateral cortex (14) for better anchoring in the bone.
- the endoprosthesis is then pushed over the proximal end of the screw and with the help of another screw which is pushed through a central hole in the endoprosthesis in direction (9), screwed into the screw in the bone, which has a thread in this area. It is advantageous if this is in the Bone-cutting thread and the thread in this screw for receiving the second screw are designed in opposite directions. It can also be advantageous if at least one of the two screws is made of a resorbable material, so that the endoprosthesis is only braced during the critical bone healing phase. In addition to screw connections, other connections such as dowels are of course also conceivable, in particular for anchoring in the bone.
- the endoprosthesis is designed with a slight curvature in order to ensure a better geometrical adaptation to the femoral neck geometry, particularly in the case of larger patients.
- FIG. 1 shows a side view of a preferred embodiment of the endoprosthesis with four ribs and a representation of the reference plane
- FIG. 2 shows an oblique view from laterally distal to the same preferred embodiment of the endoprosthesis with four ribs
- FIG. 3 shows another embodiment with Spannele -, ment for anterograde tensioning of the endoprosthesis in the bone
- FIG. 4 an embodiment corresponding to FIG. 3 with an uninterrupted bone screw.
- Fig. 1 shows a preferred embodiment of the endoprosthesis anchored in the femoral neck with four ribs.
- the depth (7) of the ribs (1) should be at least 10% of the diameter (5) of the endoprosthesis measured at the osteotomy level (16).
- the diameter of the endoprosthesis increases in the proximal direction and forms a wide support collar (2).
- the angle (6) of the support collar on the osteotomy plane - measured in the sectional plane passing through the longitudinal axis of the endoprosthesis - should be greater than 20 °.
- the support collar opens into an end plate (3).
- FIG. 2 shows the preferred embodiment shown in FIG. 1 of the endoprosthesis anchored in the femoral neck with four ribs in a lateral distal view. This view also clearly shows the recess (10) located laterally in the bone for reducing the distal load introduction into the bone.
- FIG. 3 shows the preferred embodiment shown in FIG. 1 of the endoprosthesis anchored in the femoral neck with four ribs in a lateral distal view with a distal fixation element.
- the fixation element is designed as a screw anchor with the help of an interrupted thread for better bony integration.
- FIG. 4 corresponds to an embodiment analogous to FIG. 3.
- the fixation element in this case is an uninterrupted bone screw (8) with a cylindrical head part which has an internal hexagon (13).
- the core hole of the bone screw (8) is pre-drilled.
- the bone screw is then screwed in to a predetermined depth and the prosthesis is hammered in.
- a rod (not shown) inserted in the internal thread of the bone screw can be used as a centering aid.
- the prosthesis In its end position, the prosthesis is guided through the cylindrical part of the bone screw.
- the subsequent screwing in of a tension screw (11) creates a tension between the bone screw and the prosthesis for the primary anchoring.
- An artificial joint ball (not shown) can then be placed on a cone (12).
- This shaping ensures that the load is introduced at the implanta bone border at least essentially in the direction of the natural trabecular bone structure, as a result of which long-term stability can be achieved.
- This form of support collar is particularly advantageous for prostheses anchored in the femoral neck alone. These prostheses are naturally relatively short, so that they only have comparatively small anchoring areas. Improvements in the dimensional stability, such as those achieved by the increase in cross-section according to the invention, can increase the primary stability to such an extent, even if this improvement is only relatively small, that any remaining relative movements between the implant and the bone are below a permissible maximum value of, for example, 150 ⁇ m and a particularly good ingrowth of the implant is possible.
- the angle (6) between the surface of the prosthesis and the longitudinal axis of the prosthesis at the osteotomy plane (16) is approximately in any sectional plane (4) that extends through the longitudinal axis of the prosthesis, but not through the ribs (1) 90 °.
- the increase in cross-section is preferably such that the maximum cross-sectional area of the prosthesis in the region of the support collar (2) lying in the bone is in the range from 1.5 to 6 times the cross-sectional area of the prosthesis before the increase in cross-section. In the embodiment shown in Fig. 1, the maximum cross-sectional area of the support collar (2) within the bone is 4 times the cross-sectional area of the prosthesis before the cross-sectional increase of the support collar (2).
- An end prosthesis designed in this way with a 1.5 to 6-fold enlargement of the cross-sectional area within the bone results in a proximal loading of the bone, which stimulates the bone growth in this area in a particularly effective manner, thereby achieving a long-term stable anchoring of the prosthesis in the bone becomes.
