Abstract:
1. A prosthetic device for an anatomical feature comprising: a prosthetic member able to be fixed to the anatomical feature; a bearing including a bearing surface able to support an articulating surface for articulation thereon; and a bearing restraining member that limits movement of the bearing relative to the prosthetic member at a first time when the prosthetic device is initially implanted on the anatomical feature and that allows for increased movement of the bearing relative to the prosthetic member at a second time without surgical intervention, wherein the bearing restraining member allows for movement of the bearing relative to the prosthetic member within a first range of movement at the first time, and wherein the bearing restraining member allows for movement of the bearing relative to the prosthetic member within a second range of movement at the second time, an amount of displacement in each of the first and second ranges of movement having a nonzero value, the second range of movement greater than the first range of movement.
