Abstract:
1. An implantable acetabular assembly, comprising: a cup-shaped shell configured to be inserted into a cup-shaped site; a cup-shaped liner configured to be received within a cavity of the shell, the liner having a liner aperture and a mating feature adjacent to the aperture; and a modular screw configured to be received within the aperture of the liner, the modular screw including a first component that is positionable adjacent to a first side of the mating feature and a second component that is positionable adjacent to a second side of the mating feature opposite the first side, wherein the modular screw is configured to be rotatable within the aperture of the liner when the first component and second component are coupled to each other; wherein the first component of the modular screw is a female component having an externally threaded portion configured to be engaged with mating internal threads in a shell aperture of the shell, wherein the second component of the modular screw is a male component configured to be received within a recess in the female component so as to couple the modular screw about the mating feature, and wherein the male component includes a cavity to receive a torque driver to rotate the modular screw, wherein rotation of the male component rotates the female component to threadingly engage the internal threads in the shell aperture, and wherein the male component is coupled to the female component with at least one of a press fit connection and a snap fit connection.
