Abstract

A prosthetic socket component for articulating anatomical joints includes a shell member for being affixed to a first bone of the joint and a liner to be received in a cavity of the shell member through an opening in the shell member communicating with the cavity. The cavity has a longitudinal axis that is angularly offset from a longitudinal axis of the shell member, and the liner is rotatable relative to the shell member about the cavity axis to change the size of an angle made by a socket opening in the liner with the cavity opening. A method of implanting a prosthetic socket component includes the step of aligning a portion of the liner with one of a plurality of portions of the shell member to position the socket opening a predetermined angular distance from the cavity opening. An introducer for the prosthetic socket component includes a handle and a head for being received in the cavity with a longitudinal axis of the handle aligned with the shell member longitudinal axis. A system for implanting a prosthetic socket component includes the shell member, the introducer and the liner with the liner being mounted for rotation relative to the shell member to change the magnitude of the socket opening angle.
