Document Type and Number:
WIPO Patent Application WO/2014/043236
Kind Code:
A3
Abstract:
The present invention relates to an artificial hip joint replacement system. The system includes an acetabulum portion comprising a cup suitable to be received by a subject's acetabular bone. The cup includes a rigid portion and an elastic portion attached to the rigid portion. Also included in the system is a ball received within the cup and in contact with the elastic portion and a femoral stem attached to the ball. The elastic portion is positioned to cause expansion and contraction of a space between the ball and the rigid portion of the cup so they are further apart from one another during periods of low mechanical loads.
