Definitions

  • the present invention relates to an articulated prosthesis.
  • the invention relates more particularly to such a prosthesis which, once implanted, connects two parts of the 'human body, between which mechanical stresses are exerted. It can be in particular, on the one hand the acetabulum of the hip or the shoulder and, on the other hand, the medullary canal of the femur or the humerus.
  • the invention proposes to produce an articulated prosthesis, the structure of which is simple, the mounting of which is easy and which is reliably implanted in the organs which it connects. To this end, it relates to an articulated prosthesis, characterized in that it comprises:
  • the mobile element is received at least partially in an interior volume of the intermediate element, having at least one degree of freedom in rotation relative to this intermediate element, and in that there are provided second means allowing the movable element to be joined in translation relative to said intermediate element, these second means comprising a periphery substantially rigid, the outlet of the interior volume of this intermediate element.
  • FIG. 1 is a longitudinal sectional view, illustrating the various components of an articulated prosthesis according to the invention
  • FIGS 2, 2A and 2B are views similar to Figure 1, illustrating three stages of mounting of an intermediate element of the prosthesis of Figure 1, in the interior volume of a fixed element of this prosthesis;
  • Figures 3 and 3A are views similar to Figure 1, illustrating the introduction of a movable member of the prosthesis of Figure 1, in the interior volume of the intermediate element of this prosthesis.
  • Figure 1 illustrates an articulated prosthesis according to the invention, which is a shoulder prosthesis.
  • the person skilled in the art may produce a prosthesis according to the invention, the type of which is different, for example a hip prosthesis.
  • the prosthesis 2 illustrated in this figure 1 comprises a movable element, generally designated by the reference 4, which comprises a rod 6, of known profile, which is intended to be introduced into the medullary canal of the humerus not shown.
  • This rod ⁇ is extended by a collar 7, as well as by a spherical head 8 of diameter d, which is provided with an equatorial flat extending in an inclined manner. This means that this flat is not perpendicular to the main axis A of the flange 7.
  • the transverse dimension of this flat 10, which is denoted by, is less than the aforementioned diameter d.
  • the prosthesis illustrated in Figure 1 also includes a fixed element 12, intended to be secured to the acetabulum not shown of the shoulder.
  • This fixed element 12 has a spherical outer surface, as well as a spherical inner surface, of diameter D.
  • This inner surface extends over an angular sector greater than 180 °, so that the transverse dimension L, corresponding to the outlet 14 of the internal volume 16 of the element 12, is less than the aforementioned diameter D.
  • the inner wall of the fixed element 12 can also be hollowed out with a not shown notch, making it possible to locally widen the cross section of the housing 16. This guarantees an easier introduction of an intermediate element into this housing, like this is described in the following.
  • the prosthesis finally comprises an intermediate element 20, the external surface 22 of which defines a portion of truncated sphere, of diameter identical to that D of the housing 16.
  • This intermediate element has an internal surface 24 also spherical, the diameter of which is equal to that of of the head 8.
  • the inner surface 24 of the intermediate element 20 extends along an angular sector greater than 180 °. In this way, the transverse dimension of the outlet 26 of the housing
  • the first step is to introduce the intermediate element 20 into the interior volume 16 of the fixed element 12.
  • this intermediate element is arranged, so that its spherical outer surface 22 is in the vicinity of the outlet 14 of the housing 16. Then, this intermediate element is brought axially closer to the fixed element, so as to make it penetrate into the housing 16, as shown in Figure 2A.
  • the intermediate element 20 and the fixed element 12 are not linked in rotation or in translation, in this position of free introduction.
  • the intermediate element 20 is then made to pivot, so that its external surface 22 extends in the vicinity of the internal walls of the fixed element, as shown in FIG. 2B. Once these operations have been carried out, the intermediate element 20 has no degree of freedom in translation relative to the fixed element 12, in this position of use illustrated in FIG. 2B.
  • the transverse dimension L of the outlet 14 is less than the external diameter D of this intermediate element 20.
  • the head 8 is first tilted , so that the flat 10 extends perpendicularly to a diameter of the element 20, passing through the center of its outlet.
  • the moving element is then brought axially closer to the intermediate element. Since the transverse dimension of the flat 10 is substantially identical to that of the outlet 26, this allows free introduction of the head 8 into the housing 28, as illustrated in FIG. 3.
  • the movable element 4 is pivoted, so as to give it the arrangement illustrated in FIG. 3A.
  • the transverse dimension of the outlet 26 is less than the diameter d of the head 8 of the movable element 4, the latter cannot emerge from the interior volume 28, in the arrangement of FIG. 3A.
  • the periphery of the outlet 26 is substantially rigid.
  • the intermediate element can be made entirely of a rigid material, in particular metallic.
  • this intermediate element can be made of a deformable material, such as polyethylene, a rigid ring then being attached in the vicinity of the abovementioned outlet.
  • the invention makes it possible to achieve the objectives mentioned above. Indeed, the various constituent elements of the articulated prosthesis of the invention have a relatively simple structure.
  • the articulated prosthesis of the invention has a high resistance with respect to mechanical stresses, exerted in particular in traction.
  • the presence of the intermediate element makes it possible to transmit only to a very small extent the possible forces to which the articulated prosthesis of the invention is subjected.
