摘要:
Prosthesis (1) for joint shoulder reconstruction comprising a joint head (4) shaped to provide a spherical type coupling with a concave joint element of a glenoid component. The joint head (4) includes a metallic core (5) and a joint cap (9) made of a plastic material provided with a cavity (10) insertable on an insertion element (7) of the core (5) along a longitudinal direction (X). The insertion element (7) and the cavity (10) are configured to define shape-coupling means operating by elastic deformation such as to secure the joint cap (9) to the core (5) along the longitudinal direction (X). A plurality of penetration elements (12) are arranged between a plate (5) of the core (6) and a coupling surface (11) of the joint cap (9) to define an anti-rotation mechanism of the joint cap (9) on the core (5).
