Definitions
- Acetabular cup for a hip prosthesis with stem fixed by connection means is fixed by connection means.
- the present invention relates to the technological field of the design and manufacture of the various component parts of a hip prosthesis.
- the invention actually relates to a special innovative form of acetabular cup (i.e. that part of the prosthesis which is housed in the patient's pelvis), of the type provided with a fixing stem that inserts into the iliac bone.
- acetabular cups produced at present form a whole with the said stem, and this causes many problems and significant limitations to the application of an acetabular cup.
- the subject of the present invention is therefore an acetabular cup for a hip prosthesis, provided with a tapering stem that inserts into the iliac bone as disclosed in the appended Claim 1.
- an acetabular cup 1 according to the invention of known type as regards its structural characteristics, is provided with a tapering stem 2, also conceptually known, which, by its insertion into the iliac bone 7, acts as a means of additional fixing of the cup 1 proper.
- the said stem 2 does not form a single integral whole with the cup, but is fixed to it by connection means. It also has a plurality of longitudinal fins 2a which, when embedded in the iliac bone, prevent any rotation of the said stem with respect to the iliac bone.
- connection means take the form of a frustoconical projection 3 of the acetabular cup 1, this projection 3 being connected by a male-female force fit in a cavity 4 formed co-axially in the abovementioned stem 2, but it is also possible to make a similar fit the other way round, with the frustoconical projection being formed on the stem and connecting to a mating cavity formed in the cup.
- This form is not shown in the drawings.
- this screw must be of the type in which the head is sunk in the wall of the cup 1, in order not to interfere with the rotational movements of the ball head of the prosthesis (which is not shown in the figure), which is housed in the mating cavity 8 of the acetabular cup 1.
- an acetabular cup 1 produced in accordance with the invention it is possible, as already indicated, to insert the most suitable stem 2 into the iliac bone 7 first, and only afterwards connect it to the cup 1, which can be applied subsequently, and then proceed to further lock the two together by means of the screw 5 or some similar threaded means.
