A cotyloid implant including a screwable cup receiving an articular insert. The cup is provided with screwing elements () on the periphery thereof and more particularly in the equatorial area () thereof, the elements being used to penetrate the bone material of the acetabular cup during screwing. The cup includes an osteointegration-facilitating coating such as a selective calcium hydroxyapatite coating. The coating () is a thick coating on the convex parts of the outer surface of the cup, including areas or valleys or hollow thread elements which are left free in the screwing elements. The coating is not as thick () on raised areas or screw thread areas.

Acetabular implant and method for the production of said implant

An elastically deformable cotyloidal prosthesis including a hollow hemispherical cap which includes an outer surface including portions which are deformable while the inner surface thereof is rigid and which further includes a plastic insert having a hemispherical cavity which communicates with an outer beveled edge defining a cylindrical opening thereto. The insert is rotatably adjustable and securable relative to the inner surface of the cap.
