Definitions
- the invention relates to a femoral component for a hip endoprosthesis according to the preamble of claim 1
- the problem with non-cemented femoral components is the lack of primary stability, i.e. the initially inadequate firm anchoring and the lack of a fast bony connection between the surface of the prosthesis and the bone.
- the standard non-cemented systems result in a less targeted force transfer to the femur in that the load transfer takes place over the entire but mainly distal prosthesis socket and is therefore non-physiological. This can lead to proximal bone resorption and later instability of the prosthesis.
- the invention seeks to remedy this.
- the invention has for its object to provide a non-cemented femoral component for a hip endoprosthesis which is anchored proximally in the femur, thereby achieving a largely physiological load distribution in the proximal shaft area and largely eliminating the risk of varus-like tipping.
- the invention solves this problem with a femoral component which has the features of claim 1.
- the femoral component according to the invention has improved primary stability and thus an initial, good form fit and a proximal anchoring. This ultimately leads to a physiological strain on the femur.
- an optimal fit can be achieved with the femoral component according to the invention, which allows minimal clearance of the femur.
- the anterior and / or posterior pocket-shaped recess With cancellous bone, there are possibilities of a quick bony connection between the prosthesis surface and the bone. This results in a wide range of correction and optimization options with regard to the initial position of the prosthesis. Especially in the case of osteoporosis, options for bridging missing cancellous bone are valuable.
- FIG. 1 shows a perspective illustration of a femoral component according to the invention
- FIG. 2 shows a side view of the femoral component according to FIG. 1 with the surrounding femur;
- FIG. 3 shows a cross section along the line III-III in FIG. 2.
- the femoral component shown in FIGS. 1 and 2 for a hip endoprosthesis to be fixed without cement has a distal end 1 intended for insertion into the medullary cavity 18 of the femur 19, a proximal shoulder part 2 with a neck 3, to which a spherical head can be fastened, one between the shoulder part 2nd and end 1 lying shaft part 4 with longitudinal axis 5 and length L, an anterior side surface 12, a posterior side surface 13, a medial side 14 and a lateral side 15.
- indentations 6 can also be provided only on the anterior side surface 12 or only on the posterior side surface 13.
- several such depressions 6 can also be provided anteriorly and / or posteriorly.
- the depressions 6 have an average depth of 0.1 to 6.0 mm, preferably of 0.2 to 4.0 mm and have an average extent of 5 to 70 mm, preferably of 8 to 50, measured in the direction of the longitudinal axis 5 mm.
- the volume of the depressions 6 is 320 to 800 mm 3 , preferably 330 to 600 mm 3 .
- the proximal boundary 10 of the recess 6 is laterally measured at a distance of 5 to 60 mm, preferably 8 to 50 mm, from the proximal boundary 11 of the proximal zone 8 of the shoulder part 2.
- the recess 6 has a proximal delimitation length of 8 to 45 mm, preferably 10 to 35 mm, which is transverse to the longitudinal axis 5, and a distal delimitation length of 4 to 40 mm, preferably 8 to 30 mm, likewise transverse to the longitudinal axis 5.
- Both the anterior and posterior side surfaces 12, 13 and the medial and lateral sides 14, 15 converge conically towards the end 1 of the femoral component, so that a decreasing cross-sectional area results.
- the depression 6 is connected to the proximal zone 8 of the shoulder part 2 via a channel 7 running approximately in the direction of the longitudinal axis 5 on the surface of the shoulder part 2.
- An anterior channel 7 is visible in FIG. 2.
- a corresponding channel is also provided for the invisible posterior recess 6.
- the channels 7 have an average cross-sectional area of 4 to 120 mm 2 , preferably of 8 to 50 mm 2 .
- grooves or ribs 9 can be provided in the proximal third of the shaft part 4 which merges into the shoulder part 2.
- the advantage of these additional grooves or ribs 9 lies in the interlocking connection between the prosthesis and femur that can be achieved thereby, in order to improve the primary stability.
- the enlargement of the surface leads to a further macroscopic cancellous anchoring.
- the positive connection leads to an increase in the torque load capacity (rotation stability, rotation lock) of the prosthesis.
- the additional grooves or ribs 9 also provide additional guidance and thus an exact positional positioning of the prosthesis during the setting process.
- the grooves or ribs 9 run in a conical-convergent manner towards the end 1 both in the antero-posterior and in the medio-lateral direction.
- the ribs can be interrupted by horizontal or oblique cuts. They serve as incisors during the placement process and prevent the femur from expanding and detonating.
- a microstructuring 16 is provided, which has an average roughness depth of 5 ⁇ m to 1000 ⁇ m, preferably of 10 ⁇ m to 600 ⁇ m.
- a microstructuring 17 is provided in the distal half of the femoral component, which has an average roughness depth of 0.5 ⁇ m to 600 ⁇ m, preferably of 1 ⁇ m to 400 ⁇ m.
- microstructuring 16 in the proximal half is different from microstructuring 17 in the distal half and is preferably coarser.
- proximal zone is provided in the area of the recess 6 for supporting and guiding tasks, this zone is used in particular by means of an appropriate surface quality, an optimization of the bony growth behavior and thus a bony integration.
- This proximal half of the femoral component, preferably the shoulder part (2) contained therein and the pocket-shaped recess (6), can be provided with a coating made of a bioactive material, preferably hydroxylapatite.
- the additional microscopic anchoring that can be achieved in this way, similar to the coarser surface structuring in the proximal half - as a superimposition on the macroscopic anchoring - improves implant adhesion and bony integration and thus long-term stability. If the coating is made of bioactive material, this leads to an improvement in the secondary stability.
- a ball head can be attached to the neck 3 in a known manner.
- the average cross section of the shaft part 4 in its distal third, including the end 1, is 25 to 120 mm 2 , preferably 40 to 80 mm 2 .
- the femoral component can consist of titanium, a titanium alloy, a cobalt chrome or an Fe-based alloy.
