  • Patent number: 10610363
    Abstract: This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centred on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

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.

  • Patent number: 8870962
    Abstract: Various embodiments of the present invention relate to an apparatus and method for reverse shoulder arthroplasty (e.g., reverse total shoulder arthroplasty). In one specific example, a glenoid component used to resurface the scapula may be provided. Of note, unlike traditional total shoulder arthroplasty the glenoid component in a reverse shoulder is convex rather than concave; it acts as a physical stop to prevent the superior migration of the humeral head—a typical occurrence in patients suffering from rotator cuff tear arthropathy (CTA).

  • Publication number: 20140309745
    Abstract: A modular, adjustable, prosthetic hip/shoulder spacer adapted to being implanted in the hip or shoulder joint; the spacer comprises a frame that supports a rotatable cylinder from which a neck extends with the ball element of the joint attached to its end, and rotating the cylinder reposition the ball in the socket; the stem is connected to the base of the frame and is implanted in the long bone (femur or humerus); the stem may be modified to include a system for delivering medication to the implantation site following surgery. The stem leg and stem base may be modified to form a modular unit to adjust the relation between a center line of the stem leg and a center line of the frame and position of the neck and ball.

  • Patent number: 8845743
    Abstract: An interlocking reverse shoulder prosthesis including a glenoid cup being implanted in the glenoid fossa having a glenoid ball, firmly attached to the central portion of the cup via Morse taper. The humeral component having a hemispherical cup attached to the neck of the implant via Morse taper in a modular fashion thereby allowing use of several neck lengths. After implantation of the glenoid cup, glenoid hall and the humeral cup, the members are assembled together for relative movement. The glenoid cup is secured by several screws or resorbable fixation studs. During range of motion, the edge of the humeral cup becomes inserted into a gap located between the glenoid cup and the glenoid ball and becomes restrained thus reducing the likelihood of dislocation during extreme range of motion.

  • Publication number: 20140156011
    Abstract: A reverse joint prosthesis to replace a “ball and socket” joint such as a hip or shoulder. In the case of a hip, the prosthesis comprises an acetabular cup for implanting in an acetabular socket. The acetabular cup is secured to the acetabular socket of the pelvis. The acetabular cup has a stem extending from the center of a concave portion thereof and an acetabular ball is attached to the stem. A femoral implant is provided with a femoral cup attached to the proximal end thereof. The femoral cup has a stem which can be constructed in a modular fashion with several stem lengths to accommodate different size patients. After implantation of the acetabular cup and ball and the femoral cup, the members are assembled together so that the femoral cup can articulate on the acetabular ball. The prosthesis of the invention has substantially reduced likelihood of dislocation during extreme ranges of motion.
