Glenoid anchor for a shoulder joint prosthesis

A glenoid anchor for a shoulder joint prosthesis, of the type intended to be fixed to a glenoid cavity of a shoulder blade,

• wherein the glenoid anchor consists only of a structurally independent pin, with an internally hollow conical sleeve, which has a tapered distal end configured for being directly fixed to the glenoid cavity and an open proximal end configured for being removably attached to a prosthesis component,
• wherein said prosthesis component is a lug of either one of an anatomical prosthesis or a reverse prosthesis,
• wherein said glenoid anchor is configured for removal of said lug in order to convert the anatomical prosthesis to the reverse prosthesis or vice-versa, while keeping the structurally independent pin inside the glenoid cavity,
• wherein an outer surface of the sleeve of said pin has a trabecular structure for favouring osteogenesis and bone integration;
• wherein said pin further comprises an annular recess formed inside an internal cavity of the pin, for receiving by means of mechanical interference an edge of the lug of the prosthesis component, substantially locking the lug inside the internal cavity.
