Definitions
- the invention relates to a ceramic surface replacement prosthesis for the natural femoral head with an outer spherical surface and an inner receiving space with an inner circumferential surface.
- Surface replacement prostheses are also called resurfacing head, hip cap or cap prosthesis.
- the outer surface of the resurfacing prosthesis is spherically shaped and is inserted either directly into the natural pelvis or into an artificial acetabulum, which in turn is anchored in the natural pelvis.
- Previous ceramic surface replacement prostheses are largely based on known metallic designs and are basically cemented.
- the inner surface of the inner receiving space is provided with cement pockets and a centering pin.
- a cementless version of a surface replacement prosthesis would be very advantageous because of the heat generation of the cement.
- Another advantage would be an embodiment without centering, since the loss of bone tissue by the attributable center hole is smaller.
- the invention has the object to improve a ceramic surface replacement prosthesis according to the preamble of claim 1 so that no necrosis of the bone tissue is caused during implantation and there is also no loss of internal bone tissue.
- Internal bone tissue is understood to mean bone tissue that is not visible from the outside, in contrast to external bone tissue, which is visible from the outside and is processed before the surface replacement prosthesis is put on.
- this object is achieved in that the inner lateral surface is at least partially provided with an osseointegrative coating or is designed osseointegrativ and / or the lateral surface is formed as a self-tapping thread.
- an osseointegrative surface coating or design of the inner lateral surface By means of an osseointegrative surface coating or design of the inner lateral surface, a firm and durable anchoring of the surface replacement prosthesis on the femoral head is achieved.
- An osseointegrative design of the lateral surface is, for example, by designing the near-surface area of the lateral surface in the green state of the ceramic surface replacement prosthesis achieved with the aim of a suitable open-pore structure.
- a coating of the lateral surface in the sintered state of the ceramic surface replacement prosthesis, for example, with structured coverings of titanium alloys is suitable.
- the surface replacement prosthesis is attached to the femoral head without cement. This applies to all inventive embodiments. It also arranged in all embodiments, no central centering pin in the receiving space.
- the lateral surface is designed as a self-tapping thread.
- the attachment is substantially improved, so that can be dispensed with the cementing or centering.
- the thread is conical or cylindrical.
- the femoral head usually has to be processed least.
- the steepness of the thread is essential: After insertion of the femoral head with the surface replacement prosthesis In the acetabulum at the end of the operation, the interface of the surface replacement prosthesis to the femoral head is axially biased by the natural ligament tension and muscle tone.
- the greater the steepness of the thread the higher the torque required for unintentional release of the connection; such a releasing torque about the axis of symmetry of the surface replacement prosthesis can occur by rotational movements of the leg during movement exercises.
- Increasing ingrowth of bone tissue into the osseointegrative-shaped interface between femoral head and surface replacement prosthesis increases the fit between elements of the bone tissue ("trabeculae") and the osseointegrative structure, the safety of the interface.
- the thread should therefore have a pitch greater than 2 mm / rev
- the thread can be formed more smoothly.
- the number of threads, the tooth shape and the pitch can be optimized in terms of primary anti-rotation and axial strength within wide limits and are to be produced on conventional CNC machines during the green machining of the ceramic surface replacement prostheses. Even very steep angles up to 90 ° can be carried out, whereby these can be mounted with an impact instrument.
- cementless surface replacement prostheses according to the invention are shown. 1 shows schematically a section through a natural thigh neck 9 or femoral head 3 with attached inventive surface replacement prosthesis 1 made of a ceramic.
- the outer surface of the surface replacement prosthesis 1 is spherical and is used either directly in the natural basin or in an artificial pan, which in turn is anchored directly or indirectly in the natural basin.
- the surface replacement prosthesis 1 has an inner receiving space with an inner circumferential surface 4, with which the surface replacement prosthesis 1 is placed on the femoral head 3.
- the inner circumferential surface 4 of the receiving space is preferably conical. But it can also, as shown in Figure 1, be crowned.
- the surface replacement prosthesis 1 is fastened on the femoral head 3 without cement. This applies to all inventive embodiments. There is also no central centering pin arranged in the receiving space.
- the inner circumferential surface 4 is provided with an osseointegrative coating 6 or is designed osseointegrative.
- the inner circumferential surface 4 of the receiving space is formed as a self-tapping thread.
- FIG 2 shows a surface replacement prosthesis 1 according to the invention, in which the lateral surface 4 of the inner receiving space is designed as a truncated cone and provided with a multi-course coarse thread.
- a 2-course self-tapping thread is shown as an example.
- the inner lateral surface 4 is provided with an osseointegrative coating 6 in addition to the thread.
- An osseointegrative coating 6 is also referred to as a direct-to-bone coating.
- the preparation of the seat during the operation is carried out with a correspondingly shaped milling instrument. After placement of the surface replacement prosthesis 1, this is fixed by a clockwise rotation. To correct the height, the surface replacement prosthesis 1 could be released again by turning to the left and, if necessary, the seat can be milled.
- FIG. 3 shows a surface replacement prosthesis 1 according to the invention with a conical, self-forming, four-course thread with a pitch s / 4.
- FIG. 4 shows a section through a surface replacement prosthesis 1 with a common thread 8 and
- FIG. 5 shows a surface replacement prosthesis 1 with a four-prong thread.
- FIG. 6 shows a surface replacement prosthesis 1 according to the invention with a cylindrical self-forming 6-thread thread.
- the pitch of all threads is 1 to 20 mm / rev, preferably 2 to 10 mm / rev, more preferably 3 to 6 mm / rev.
- the pitch is preferably 1 -2 mm / revolution, 2-4 mm / revolution for a 2-speed thread and 3-6 mm / revolution for a 3-thread.
