Abstract
A plug is provided for securing two components of an orthopedic implant where at least one of the components is formed of material softer than the material of the plug. In a preferred embodiment the components comprise concentric cups rotatable with respect to one another about an axis. The components are fixable using a plug to prevent rotation of the components with respect to each other. The invention is preferably used with an acetabular shell and liner of a hip implant wherein the shell is comprised of metal material and the liner is comprised of a polymer or other similar soft material. The plug has a serrated head and a distal lip or anchoring edge to provide securement at more than one location along the length of the plug. The plug is insertable into a common opening defined by aligned recesses or openings of the two components of the implant.
