A shoulder prosthesis system has a glenoid socket with an interior face with couplers and an exterior face being a concave articulating face with a first longitudinal radius of curvature and a second latitudinal radius of curvature. A backing plate has an outer extent and an inner extent. The outer extent has a cylindrical base and a recess around the periphery and a plurality of tapered bores extending through the outer extent spaced between the recess and the center of the backing plate. The inner extent is formed with a projection with threads adapted to be rotatably coupled into a scapula of a patient. The couplers of the outer extent are adapted to snap couple with the recesses of the glenoid socket.
