Abstract: A total shoulder prosthesis includes a glenoidal component a substantially hemispherical convex articular surface and of which a center of curvature is adapted, when the prosthesis is implanted, to be located in the glenoid cavity or in the immediate vicinity thereof, and a humeral component defining a concave articular surface adapted to cooperate with the convex articular surface of the glenoidal component. The concave humeral articular surface is defined by a metallic part of the humeral component to thereby reduce a space requirement of the prosthesis.

Abstract: The glenoidal component for shoulder prosthesis according to the invention comprises a base adapted to be immobilized on a patient's glenoid cavity and an element adapted to be added on the base and defining a convex surface of articulation of which at least a part is globally in the form of a portion of sphere and centred on a geometric point, the base being provided with a part centred on an axis and on which is added the afore-mentioned element. When the component is in assembled configuration, the geometric centre and the afore-mentioned axis are offset with respect to each other.

Abstract: The aim of this method is to improve the efficiency and ease of implanting a means for suturing a soft tissue to a bone, while allowing it to be carried out by arthroscopy in particular.

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.

Abstract: A set of humeral components for a total shoulder prosthesis, wherein each component is formed by an anchoring stem and a metaphyseal part which defines a concave surface of articulation in the form of a portion of a sphere. The offset between an axis of symmetry of this surface and a central axis of the metaphyseal part varies between the different components of the set. This makes it possible to limit or to avoid, by a reasoned choice of the humeral component used, an interference with the pillar of the scapula during a movement of adduction.

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 most adapted to the orientation of the resectioned surface from a set of components in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

Abstract: This total shoulder prosthesis comprises a glenoidal component, defining a substantially hemispherical convex articular surface and of which the centre of curvature is located in the glenoid cavity or in the immediate vicinity thereof, and a humeral component defining a concave articular surface adapted to cooperate with the convex articular surface of the glenoidal component. The concave humeral articular surface is defined by a metallic part of the humeral component, this avoiding having to resort to a part made of plastics material which would increase the space requirement of the prosthesis.

Abstract: A prosthesis of the upper extremity of the humerus of the type that comprises a stem anchored in the humeral canal and provided on its upper or metaphyseal part with a bearing surface against which rests a hemispherical cap suitable to interact with a shoulder socket, wherein the stem is selected from a set of stems each provided with a bearing surface having a tilt angle that differs with respect to a longitudinal axis of each stem. A set of humeral stems comprises several stems each of which is provided with a bearing surface having a tilt angle that differs with respect to the longitudinal axis of each stem.

Abstract: The object of the invention is an implantable system (16) for anchoring stitching threads (2) within a bone tunnel (3), said system comprising an implantable device (1) and a complementary piece (17), the said device being formed by a single piece produced from bioresorbable material, and comprises:

Abstract: A humeral prosthesis including a shaft adapted to be anchored in a medullary canal of humerus, a metaphyseal portion extending upwardly and endwardly from said shaft and being joined at its outer end to a flange which is adapted to support a dome to cooperate with a glenoidal cavity of a shoulder wherein the metaphyseal portion includes an inner part having at least one antero-posterior rib which is structured to provide an anatomical support for humeral tuberosities and which the at least one rib is oriented at an angle of between 45° to 135° with respect to a frontal plane of the prosthesis.

Abstract: A humeral prosthesis of such a type that is provided with a rod intended to be anchored in the humeral canal of a patient, a metaphyseal element extending the rod upward and towards the inside, being this metaphyseal element attached at an area of connection to a flange that serves as support for a generally hemispheric cap capable of interacting with the shoulder socket. The area of connection is arranged approximately along a median line of the mentioned flange and the area of connection extends only over a portion of the mentioned median line so as to establish outside of the area of connection, or outside of a portion of the area of connection, a clearance zone for the joining and fusing of the osseous fragments of the metaphysis.

Abstract: A device for attaching a prosthesis including a metal foundation provided with a plate integrally formed with at least one anchoring pin consisting of elastically deformable wings and at least one the screw cooperating with a nut. The screw goes through the pin, to spread the wings into a position away from a longitudinal axis of the pin. The anchoring pin comprises an internal bore having a cylindrical base connecting the pin to the plate, and a circular counter-bore adjacent the bore of greater diameter than the internal bore of the pin, making it possible to spread the wings while maintaining their rigidity over their entire length.

Abstract: A humeral prosthesis including a shank having a metaphyseal part having a housing therein with a semi-spherical portion in which housing is introduced a sphere to which is secured a bearing surface hemispherical cap adapted to be received within the glenoid cavity of a shoulder. A securing element is provided which extends through the metaphyseal part of the shank for securing the sphere within the housing at a predetermined position with respect to the shank.
