Abstract
A flexible prosthetic cover (12) shaped to form a replacement nucleus pulposis for an intervetebral disc comprises an aperture for the introduction of filling material therein, and an elongate introducer member (28) configured to pass into the aperture. The cover has a strengthened portion (26) substantially opposite the aperture for engaging the distal end (42) of the member, the strenghtened portion and the said distal end being arranged to interlock, for facilitating orientation of the cove, for example so as to prevent relative rotation there between.
