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.

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.

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 centered 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: 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: 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: An instrument including a cutter (2) mountable on a cutter 32 spindle (1) and shaped in such a way that it also acts as a test cup 33 engageable by a test head of a femoral prosthesis. The cutter (2) may be attached to the pelvis (34) by means of nails (29), and the cutter position is detected by sighting means (32) on the cutter spindle (1). The sighting means (32) are then used to arrange the final cup in the same position as the cutter (2) so that the position of the final cup may be selected in such a way that the risk of joint dislocation is reduced.
