  • Publication number: 20220151788
    Abstract: A glenoid anchor for a shoulder joint prosthesis, fixed to a glenoid cavity of a shoulder blade. 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. The prosthesis component is a lug of either one of an anatomical prosthesis or a reverse prosthesis. The 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. An outer surface of the sleeve of said pin has a trabecular structure for favouring osteogenesis and bone integration.
