摘要：
A Joint prosthesis (1, 10, 100) includes a Prosthetic Component (2, 20, 200) and a retaining screw (6, 60, 600), which has a Geometry Interference (5, 50,500) adapted to allow rotation relative limit Displacement, longitudinal relative, and make these inseparable to Prosthetic Component (2, 20, 200) and retaining screw (6, 60,600).The Geometry of interference can be in the form of a Ring attached to the retaining screw (6) at a smaller diameter portion of the body of the screw (6),Or in the form of one or more Wings Bent Inward, integrated the Prosthetic Component (20) and distributed diametrically around its base, or in the form of a uniform projection,Conical and Hollow of the lower portion of the Prosthetic element (200).Also a process for the production of a joint prosthesis (1, 10, 100) is presented, which includes the steps of forming a Prosthetic Component (2, 20, 200) includes a Central Hole (8)80) to receive the locking screw (6, 60, 600), form a retaining screw (6, 60, 600) Whose Body includes a smaller diameter portion (62, 602)Insert the retaining screw (6, 60, 600) in the central Hole (8, 80) of the Prosthetic Component (2, 20, 200), and form an interference geometry (5, 50, 500),Between the base of the Prosthetic Component (2, 20, 200) and the body of the retaining screw (6, 60, 600).Un conjunto protésico (1, 10, 100), que incluye un componente protésico (2, 20, 200) y un tornillo de retención (6, 60, 600), el cual dispone de una geometría de interferencia (5, 50, 500) adaptada para permitir la rotación relativa, limitar el desplazamiento longitudinal relativo, y tornar indisociables a dichos componente protésico (2, 20, 200) y tornillo de retención (6, 60, 600). Pudiendo la geometría de interferencia ser en la forma de un anillo sujetado al tornillo de retención (6) en una porción de menor diámetro del cuerpo de este tornillo (6), o en la forma de una o mas alas dobladas hacia adentro, integradas al componente protésico (20) y distribuidas diametralme
