Abstract: Prosthetic systems, devices, and methods for attaching prosthetic joint components to a vault-shaped portion of the anatomy. A device for attaching a glenoid joint component for a shoulder prosthesis to a glenoid cavity includes a body adapted to extend into the cortical bony vault of the glenoid cavity for supporting the glenoid joint component and a plurality of contact arms secured to the body and projecting outwardly from a central longitudinal axis of the body to define contact surfaces for engaging an internal face of a peripheral wall of a glenoid vault.
