Definitions
- Implantable prosthesis with at least two cross-adjustable sections and use of adjustable sections
- the invention relates to an implantable prosthesis with at least two mutually adjustable sections, in particular a prosthesis for the upper end of a human upper arm with a shaft which can be inserted into its humeral canal and a dome-shaped joint head which can be assigned to the joint socket adjacent to the upper arm and which is connected to it by means of - both to it as well as to the shaft one insertable plug or the like into a hole. having a peg-like shape - washer of circular circumference to an end face of the shaft in an eccentric position - to the central axis thereof - can be connected.
- the invention also covers the use of adjustable sections and an intermediate washer on an adjustment plane.
- Such a joint prosthesis can be found in EP 0 549 480 AI.
- a central spigot protrudes from the washer on both sides.
- An eccentric bore is provided in the joint head for the plug on the head side and a ring of smaller bores around this for receiving an axially parallel fixing pin which engages both in this and in the intermediate disk.
- the adjustment of the joint or humeral head takes place gradually, so it cannot be adapted to the circumstances in all situations.
- the construction of this shoulder joint prosthesis does not allow the cutting axes or resection axes to be displaced.
- EP 0 712 617 AI also describes a joint prosthesis in the shaft of which the joint head is supported by means of a ball joint. This also does not offer fine tuning of the joint head. Knowing this state of the art, the inventor has set himself the goal of designing a prosthesis of the type mentioned at the outset in such a way that when it is adapted to the particular anatomical conditions of the human bones to be connected to it, fine stone adjustment is also possible without problems.
- the mutually adjustable sections are arranged to be infinitely adjustable relative to each other about axes on at least one adjustment plane, preferably one of the socket pins should be arranged at a radial distance from the axis of the intermediate disk.
- the shaft and joint head - or two parts of other implant prostheses that can be adjusted accordingly - can be continuously shifted against each other on that face or parallel to it.
- the washer - which can be inserted into a recess of one of the adjacent sections which has the same shape - is to be inserted with a central plug pin into a corresponding recess which is eccentrically formed in a connecting plane of the joint head; the other - eccentrically attached - plug pin is assigned to the end face of the shaft. That connection level also determines one of two adjustment levels of the prosthesis; the other lies in the face of the shaft.
- the diameter of the intermediate disk correspond approximately to half the diameter of the joint head and its height approximately to the respective height of its plug pins;
- the height of the intermediate washer should be approximately one third of its diameter with a preferred bolt diameter, the length of which corresponds to the diameter of its intermediate washer, such as approximately 1: 2.5 to 1: 3.0.
- the radial distance of the eccentrically provided plug pin from the axis of the washer should correspond to approximately half the pin diameter.
- connection surface of the joint head according to the invention offers a flat sack recess displaced from its axis for inserting the intermediate washer, which is equipped with a plug pin on both sides of the washer.
- the two plug pins are radially offset from each other and allow the joint head to be moved continuously with respect to the prosthesis.
- the plug pins are preferably press-fitted into their blind holes.
- the socket pin may be slightly conical; this taper of the plug pin also ensures its seat in the cylindrical blind bore.
- the position of the intermediate disk is fixed by plugging it together with the joint head or the shaft.
- the diameter of the plug pins can measure 1 to 9 mm, preferably up to 7 mm.
- the intermediate or eccentric disc then has a diameter of 10 to 35 mm - preferably 12 to 30 mm - and a thickness of 2 to 8 mm, preferably 3 to 7 mm.
- the flat recess for the washer in the spherical joint head of the implantable prosthesis is displaced from its central axis by up to 10 mm, preferably up to 8 mm.
- FIG. 1 a schematic side view of a modular shoulder joint prosthesis with an intermediate disk assigned to a shaft and a joint head that can be placed on this, in a separated state;
- FIG. 4 shows a cross section through FIG. 2 along the line IV-IV;
- Fig. 12 an enlarged compared to Fig. 10
- a prosthesis 10 for a human shoulder joint has a shaft 12 with an end face 14, the central axis M of which is inclined at an angle w of 45 ° relative to the longitudinal axis A of the shaft 12.
- the greatest length a of this shaft 12 measures 125 mm
- the width b of the end face 14 is approximately 14 mm
- its length e is approximately 23 mm.
- the projection length e 1, which can be seen in FIG. 2, of the end face 14 into a plane crossing the longitudinal axis A at a right angle is then 27.3 mm.
- the central axis M of the end face 14 determines the position of a blind hole 16 of diameter d of approximately 7 mm with a conical end 17 there.
- the head region 22 is opposite the free shaft end 20 of width 11 of a width of 11 mm, which ends on an inclined foot surface 18 of the shaft 14 extended to that length e or e x .
- the roughly constant cross-sectional area of the shaft run on both sides of central flat grooves 28 of width f x from here 4.6 mm and length i of 65 mm.
- the blind hole 16 of the end face 14 serves to receive a plug pin or plug pin 32 - corresponding to the round cross section of the diameter c x of 7 mm - an intermediate or eccentric disc 34 of the diameter d of 20 mm and the height n of 5 mm, on both sides is provided with such a plug pin 32, 32 a of the same height n; the shank pin 32 is radially offset at an axial distance q of 3 mm to the central axis Q of the eccentric disk 34, the second pin 32 a projects axially from the disk surface 35.
- the distance q can measure from 1 mm to 10 mm - preferably up to 8 mm.
- FIG. 8 illustrates a scale 36 oriented to the disk center Z with marking lines on the disk surface 35 a
- FIG. 9 shows the eccentric plug pin 32 with an annular press-fit area 38 of width s of 0.5 mm, which is at a distance n x of 1.5 mm from the other disk surface 35 a of the eccentric disk 34, which is attached to the plug pin 32 above an undercut 39.
- the latter is used in two variants, namely on the one hand with the press fit shown for both ends - not shown - a slightly conically tapering plug pin 32, 32 a or the other entirely without a press fit.
- the above-mentioned transverse bore 30 can receive an unrecognizable stud screw to increase the clamping force of the shaft 12.
- the central plug pin 32 a is intended for connection to the dome-like humerus or joint head 40, which on a connection surface 42 for the eccentric disk 34 offers a recess 44 of the diameter d ⁇ corresponding to its shape with a central blind bore 46 for the plug pin 32 a .
- the bore axis Q 1 lies here at an axial distance t of 3 mm to the central axis M 1 of the joint head 40, and the central axis M of the eccentric disk 34 falls into the cylinder wall of the eccentric bore 46 of the recess 44.
- the axial distance t can vary depending on the design correspondingly from 1 mm to 10 mm, preferably up to 8 mm.
- the height n 2 of the spherical head 40 of the joint head 40 which has a polished surface 41, is preferably proportional to the diameter length of the partial spherical surface and measures, for example, somewhat more than 17 mm, the diameter d 2 of the joint head 40 here somewhat more than 44 mm.
