  • Publication number: 20200229935
    Abstract: This set (J) comprises glenoid components (S1, S2, M1, M2, L1, L2) that each include a body (S1.1, S2.1, M1.1, M2.1, L1.1, L2.1) defining, on two of its opposite faces, respectively, a joint surface (S1.2, S2.2, M1.2, M2.2, L1.2, L2.2), intended to cooperate with a humeral head, and a bearing surface (S1.3, S2.3, M1.3, M2.3, L1.3, L2.3) bearing against the socket of a shoulder blade. In this set, the glenoid components are provided in several different sizes (S, M, L), respectively defined by the dimensions of the joint surface of their body. At least two glenoid components (S1 and S2, M1 and M2, L1 and L2) of which the bearing surfaces (S1.3 and S2.3, M1.3 and M2.3, L1.3 and L2.3) respectively have different dimensional geometries are provided so as to allow the surgeon to improve the durability of the mechanical cooperation between the implanted component and the operated socket.

  • Publication number: 20200229931
    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.

  • Patent number: 10695195
    Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.

  • Publication number: 20190358045
    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: 10485601
    Abstract: The instrumentation makes it possible to implant in a long bone, such as the humerus, the femur or the tibia, an implant, such as an osteosynthesis nail or a prosthetic rod, defining a longitudinal axis and including, in alignment along the longitudinal axis, two opposite terminal parts and a running part that separates the two terminal parts from one another. The instrumentation comprises a targeting ancillary tool that is adapted to target one and/or the other of the terminal parts of the implant, if applicable percutaneously, along at least one targeting axis that is transverse, or even perpendicular, to the longitudinal axis. The targeting ancillary tool is designed to be fastened laterally to the running part of the implant so as to position the targeting ancillary tool and the implant relative to one another in a predetermined configuration.

  • Publication number: 20190343658
    Abstract: A patient specific glenoid guide is provided to facilitate properly aligned implantation of a glenoid prosthesis into a patient. The guide shape is designed preoperatively based on the unique configuration of the scapula of the patient. The guide orientation is chosen preoperatively based on one or more of the bone structure of the patient, the wear pattern of the patient's glenoid cavity, the anchoring means of the glenoid prosthesis, or other aspects.

  • Publication number: 20190015119
    Abstract: A humeral guide is provided that has a first portion or member configured to be positioned on a portion of a proximal humerus. The first portion or member can be configured to rest in a complementary manner on the portion of the proximal humerus. The humeral guide can be configured with apertures defining trajectories through bone, the pin trajectories being diverging in some case and in some cases being selected to enhanced support. A second portion or member and a third portion or member of the humeral guide are configured to be positioned on first and second lateral portions of the humerus distal to a location intended for resection, e.g., between an anatomical neck and a distal end of the humerus. The second and third portions or members or portions are configured to rest in a complementary manner on the first and second lateral portions of the humerus. The humeral guide can be configured to avoid soft tissue between a bone facing side and the humerus. The humeral guide can have a removeable jig portion.

  • Publication number: 20180325687
    Abstract: Embodiments of the present invention include a convertible prosthesis that is capable of conversion from a humeral head replacement to a reverse reconstruction without any removal of parts integrated into the patient's bony anatomy (e.g. implant stems). A desired overall implant inclination angle may be achieved by matching various implant stems with various reverse inserts, thus permitting a resection surface to be matched with an implant stem selection while also permitting a desired overall implant inclination angle to be achieved through the selection of an appropriate insert.

  • Publication number: 20170273795
    Abstract: Joint prosthesis methods and apparatuses are provided. A bone graft blank is placed in the chamber of the bone press facing a contoured surface. The contoured surface can be part of the bone press or can comprise a surface of a patient specific negative that can be inserted into the bone press. A bone contact surface of the bone graft blank is disposed in the chamber to face the contoured surface of the patient specific insert negative. The bone contact surface of the bone graft blank is compressed against the contoured surface. The bone contact surface can be reshaped to form a patient specific bone graft.
