  • Patent number: 11344422
    Abstract: The improved glenoid fossa prosthesis for repair of a scapular deficient patient includes a base with a fixed flange, and a separable flange. A conical taper on the base and a complimentary locator edge positively orient the separable flange when joined with the base for affixation by screw. A plurality of flange fixation screws penetrates the scapular tissue between the flanges for affixation of the flanges thereto. The flange thickness is variable to approximate the topography of the scapular tissue in the affixation area to minimize tissue trimming during fitment. A cutting mask attaches to the deficient scapula in the glenoid fossa area to guide the physician in trimming scapular tissue for fitment. A cortical screw further fixates the base to the scapular tissue. A second conical taper on the base serves as a mount for a glenoid sphere (reverse shoulder) or socket (standard shoulder) repair configuration.

  • Patent number: 8940054
    Abstract: An implant system for total shoulder arthroplasties, hemi shoulder arthroplasties, and “reverse” total shoulder arthroplasties including a humeral stem having an enlarged head portion with interfaces adapted to removably receive various modular interchangeable components, such as articulating liners, spacers, and adapter inserts. The humeral stem functions as a universal platform that may be used in either conventional or “reverse” total shoulder arthroplasties, as well as hemi shoulder arthroplasties, and may remain implanted in place during a revision in which the implant system is converted between the foregoing configurations, for example.

  • Publication number: 20150025642
    Abstract: A method of installing a prosthesis assembly includes installing a base component in a prepared glenoid vault, axially aligning a plurality of slots in one of a stretched glenoid bearing component and a base component with a plurality of ridges in the other of the glenoid bearing component and the base component, each of the plurality of slots having a maximum length which is greater than a maximum length of a respective one of the plurality of ridges, engaging each of the plurality of ridges with the respective one of the plurality of grooves thereby rotatably coupling the glenoid bearing component and the base component and limiting axial movement of the glenoid bearing component relative to the base component, and placing the bearing surface into articulating contact with a humeral head.

  • Publication number: 20150025641
    Abstract: A shock-absorbing shoulder replacement system has a glenoid cup suitable for affixing to the glenoid surface of a scapula, ahead positioned so as to bear against the glenoid cup, a rod affixed to or integral with the head on the side of the head opposite the glenoid cup, a humeral component having a shaft suitable for receipt by the humerus and having a portion extending outwardly of the humerus, and a resilient member cooperative between humeral component and the bead such that the head is resiliently mounted in relation to the humeral component. The portion of the humeral component has a receptacle therein suitable for receiving an end of the rod therein. The rod has a threaded surface that can be connected to a nut such that a distance between the head and the humeral component can be adjusted.

  • Patent number: 8936645
    Abstract: A surgical process for resurfacing a head of a humerus has the steps of applying a jig over a surface of the head so as to define a separation line between the head and the humeral shaft, sawing along the separation line so as to separate the head and the humeral shaft so as to expose an end of the shaft, applying a resurface implant over an exterior surface of the head, and affixing the head having the resurface implant thereon onto the exposed end of the shaft. The head is shaped so as to smooth the exterior surface of the head prior to the step of applying the jig. A hole is formed through the head so as to extend into the shaft. A stem of the resurface implant extends through the hole in the head and into the hole in the shaft.

  • Patent number: 8932361
    Abstract: An apparatus and modeling method of the present invention includes the successive steps of generating cartographic data representative of points belonging to a glenoid surface; distinguishing from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first surface part being situated farthest down in the vertical direction in relation to the scapula; calculating from the first group of cartographic data a first ellipsoid portion that coincides substantially with the first surface part; and obtaining a theoretical glenoid surface from the first ellipsoid portion. By virtue of the theoretical glenoid surface obtained by this method, it is possible to assist the surgeon in optimizing the position of implantation of a glenoid component and to produce a glenoid component “made to measure” for the scapula that is to be fitted with a prosthesis.

  • Publication number: 20150012104
    Abstract: Method and set of surgical instruments for fitting a shoulder prosthesis, and the shoulder prosthesis. The proposed method seeks to interpose a bone graft between the previously prepared glenoid surface (G) of a scapula (S) of a patient's shoulder and the face of a glenoid prosthetic component opposite the articular surface. The set of instruments permit the bone graft to be taken from the upper epiphysis of the humerus (H), either in situ or ex vivo.

  • Patent number: 8906103
    Abstract: A prosthesis may include a stem, an adaptor and a head. The stem may include a longitudinal axis. The adaptor may include a first taper having a first taper axis of symmetry. The head may be rotatably supported by the adaptor and may include a semispherical articulating surface defined by a central axis of symmetry that is angled relative to the first taper axis of symmetry. The head may be coupled to the first taper and may be positionable relative to the stem through relative rotation between the head and the stem about the first taper axis of symmetry to adjust a radial offset of the head relative to the longitudinal axis of the stem. The head may be adapted to be received in a glenoid cavity of a scapula.

  • Patent number: 8888855
    Abstract: Disclosed herein are components of a reverse shoulder prosthesis. In an embodiment, a reverse shoulder prosthesis includes a humeral adapter tray configured to sit near a resected surface of a humerus, the humeral adapter tray comprising: a cavity; a central bore; and a distal face including a boss, the boss: (i) configured as an extension of the distal face, (ii) posteriorly offset from the central bore by at least 10 mm, and (iii) configured to engage a humeral stem; and a humeral liner comprising: a distal rim configured to sit within the cavity of the humeral adapter tray; and a concave articulating surface configured to mate with a convex articulating surface of a glenosphere. In an embodiment, the boss, in addition to being posteriorly offset, is superiorly offset from the central bore by at least 8 mm. In an embodiment, the reverse shoulder a humeral stem which engages the boss.
