摘要

The cotyle structure, especially for an acetabular implant or replacement, consists of a cup-shaped body (2) with one or more holes (3) for a pelvic fixing. Each hole is fitted with a plug (6) that is attached provisionally to its inner walls and can be broken off when the hole is required for use. Each plug has a cylindrical body with a blind inner cavity (7) and is connected by its outer surface to the inner walls of the hole, which have a spherical section to receive a fixing screw head and an adjoining conical section adjacent to the outer surface of the structure.
