Definitions

  • the present invention relates to an improved shoulder prosthesis.
  • the field of the invention relates to prostheses used in orthopedic surgery for reconstructing the shoulder joint, i.e. the humeral bone segment whose head is articulated with the glenoid.
  • - standard prosthesis also called anatomical, in which the prosthesis accurately reproduces the anatomy of the humeral bone, with the humeral head integral with the stem which is implanted in the diaphyseal channel of the humerus; the prosthesis is completed with the glenoid component, in turn fixed to the glenoid and on which the humeral head is articulated;
  • the shoulder prosthesis surgery described above comprises, in both cases, the resection of the humeral head of the humerus to which the prosthesis is to be applied, in order to expose the diaphyseal channel, the implant seat of the humeral stem.
  • the plane of this resection is formed in particular with an angle, with respect to the anatomical axis of the humerus, which is different in the standard prosthesis and reverse prosthesis. In a standard implant, for example, this angle is about 135°, in a reverse implant it is about 150° .
  • the choice of the angle of the resection plane immediately restricts the type of standard or reverse implant to be used.
  • the surgeon however often finds that during surgery it is necessary to change the indication of the initial type of prosthesis (for example a standard prosthesis) , in relation to the anatomical state of the patient (which, in the example considered, may make it preferable to use the type of reverse shoulder prosthesis) .
  • the main objective of the present invention is to provide a new shoulder prosthesis which, with respect to traditional prostheses, offers surgeons the possibility of choosing, in situ or during surgery, the type of standard or reverse prosthesis to be used, without the necessity of applying modifications to the resection plane of the shoulder prosthesis of the standard type.
  • a further objective of the invention is to avoid the necessity of additional surgical interventions on the humeral head, traditionally necessary for passing from the standard type of shoulder prosthesis to the reverse type of shoulder prosthesis.
  • Another objective of the invention is to make it no longer necessary to have distinct medicated prosthesis components between standard and reverse prosthesis applications .
  • the shoulder prosthesis of the invention offers the advantage of making the resection of the humeral head univocal, in order to allow surgeons to choose the type of application, standard or reverse, directly at the moment of surgery. In this way, the choice of the shoulder prosthesis to be applied can be made in relation to the anatomical state observed during surgery, without having to correct the resection plane of the humeral head with respect to that of the standard prosthesis .
  • the invention therefore also avoids having to resort to traditional invasive interventions, normally required when the type of intervention must be modified with respect to that initially established.
  • figure 1 illustrates the type of standard shoulder prosthesis implant
  • FIGS. 7 to 10 illustrate the shoulder prosthesis of the invention, in its reverse configuration
  • FIG. 11 illustrates a perspective view of the detail of the humeral stem of the prosthesis of the invention
  • FIG. 12 and 13 illustrate the stem of figure 11, in standard and reverse applications of the shoulder prosthesis, respectively.
  • the standard application of the shoulder prosthesis illustrated in figure 1 comprises the insertion, in the diaphyseal channel of the humerus 2, of a stem 1, in turn provided with a humeral head 3 articulated on the glenoid 4.
  • a resection is effected by surgery on the anatomical humeral head according to the resection plane 5, whose axis 6 is tilted, with respect to the axis 7 of the humerus 2, by an angle a, normally equal to 135°.
  • the resection of the head of the humerus 2 is effected on the plane 10, defined by a reverse element 8, in turn articulated on the glenosphere 9.
  • the angle ⁇ which is formed between the axis 11 of the above resection plane 10 and humeral axis 7 is normally about 150°.
  • the correction described above also has the disadvantage of requiring specific equipment, which is distinct between the standard and reverse shoulder prosthesis, and therefore reciprocally incompatible.
  • the prosthesis of the invention comprises a humeral stem 12 provided with a conical proximal female seat 13, suitable for housing a standard adaptor 14.
  • the latter is provided in particular with a male cone 15, which is engaged inside the above seat 13.
  • the adaptor 14 also has a cone bit 16, protruding from the side of the humeral head 17 and suitable for being engaged inside a corresponding seat 18 of the same.
  • the axis 22 of the respective resection plane 21 forms, with the axis 23 of the stem 12 of the prosthesis, the angle a (for example 135°) required for standard applications.
  • the shoulder prosthesis of the invention illustrated in figure 7 maintains the structure of the stem 12, provided with a conical proximal female seat 13 and a threaded hole 20.
  • a reverse adaptor 25 is fixed on the above-mentioned female seat 13, composed of a discoidal body which, on the stem side 12, has a male cone bit 26 suitable for being engaged inside the same female seat 13.
  • the same adaptor 25 has a housing 27 for the reverse insert 28.
  • a seat 19 for the fixing screw in the threaded hole 20 of the stem 12 is also envisaged on the reverse adaptor 25.
  • the adaptor 25 now described exerts the function of fixing the reverse insert 28 to the stem 12, in particular for engagement of the connection 29 of this insert 28 to the inside of the cited housing 27.
  • the reverse insert 28 On its proximal side, the reverse insert 28 has a seat 30 for the glenosphere 31 of figure 9.
  • the reverse version of the shoulder prosthesis of the invention maintains the standard resection plane 21 tilted by the respective angle a (for example 135°) , but it also has the inclination ⁇ of the reverse shoulder prosthesis plane 32 (for example equal to 150°) formed between the axis 23 of the stem 12 and axis 33 of the reverse plane 32.
  • the humeral component of figures 7 and 8 is completed, in the reverse shoulder prosthesis illustrated in figures 9 and 10, with the glenosphere 31, in turn fixed to the anatomical glenoid by means of a plate 34 and screws 35.
  • the prosthesis of the invention is suitable for being converted from the standard application to the reverse application, thanks to the preservation of the standard resection plane 21 also in the reverse application of the shoulder prosthesis with the plane 32 tilted by the respective angle ⁇ .
  • This result is possible due to the simple application, in the conical proximal seat 13 of the stem 12, of the reverse fixing adaptor 25 of the respective reverse insert 28 which defines the above- mentioned reverse plane 32.
  • the proximal part 36 of the stem 12 of figure 11 has a flared configuration, i.e. developing from the distal part 37 towards the proximal part 36.
  • the secondary stability of the prosthesis of the invention is obtained thanks to the presence, on the above proximal part 36 of the stem 12, of a cage-structured portion 38, provided with apertures 39 which allow the regrowth of the bone tissue, occupying the internal space or cavity 40 of the same stem 12.
  • the structure of the stem 12 of the invention internally containing the above cavity 40, allows a homologous bone to be housed in the latter (for example taken from the humeral head resection) , or another material suitable for stimulating the regrowth of the bone inside the stem.

Abstract

La présente invention concerne une prothèse d'épaule, pourvue d'une tige humérale (12) ayant un réceptacle femelle proximal (13) adapté pour recevoir de façon interchangeable des adaptateurs pour l'application standard de la prothèse d'épaule (14) et inverser l'application de la prothèse d'épaule (25), respectivement. De cette manière, la prothèse d'épaule de l'invention peut être convertie de l'application standard à l'application inverse, en maintenant l'angle (a) du plan de résection standard (21) également dans l'application inverse de la prothèse d'épaule avec le plan de résection (32) incliné de l'angle respectif (β). Par rapport à l'art connu, la prothèse d'épaule de l'invention présente l'avantage de rendre la résection de la tête humérale univoque, afin de permettre aux chirurgiens de choisir le type d'application, standard ou inversée, directement au moment de la chirurgie. De cette manière, le choix de la prothèse d'épaule à appliquer peut être fait en fonction de l'état anatomique observé au cours de la chirurgie, sans avoir à corriger le plan de résection de la tête humérale par rapport à celle de la prothèse standard.
