ABSTRACT:
An extraction device (10,110) for removing a socket bearing insert (12) from an acetabular cup (14) in an acetabular prosthesis in which an extracting member (30, 130) is adapted for attachment to a groove (20) in the insert (12). The extraction device (10, 110) includes a support in the form of a sleeve (38, 138) which bears against the rim of the acetabular cup (14). The extraction device (10, 110) has means for providing an axial force exclusively between the extracting member (30, 130) and the support such that no force is transmitted to a bone to which the acetabular cup (14) is attached.
