Patent ID: 8172851

Claim:
A prosthetic device having a first, shrouded configuration and a second, constrained configuration, the device comprising: a liner comprising: a mating surface that is configured to receive adhesive; an articulating surface that is configured to receive an opposing articular component; a rim; and at least one constraining extension that extends from the rim, the at least one constraining extension having an inner side and an outer side; a shroud that couples to the liner in the first, shrouded configuration to shield the liner from adhesive, the inner side of the at least one constraining extension frictionally engaging the shroud in the first, shrouded configuration to couple the shroud to the liner, wherein the shroud includes a central hub and a rim around the central hub, the at least one constraining extension of the liner extending through an opening between the central hub and the rim in the first, shrouded configuration; and a guard that couples to the liner in the second, constrained configuration, the guard frictionally engaging the outer side of the at least one constraining extension in the second, constrained configuration to capture the opposing articular component in the liner.
