Abstract: A cotyloid implant including a screwable cup receiving an articular insert. The cup is provided with screwing elements (11) on the periphery thereof and more particularly in the equatorial area (2) 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 (16) 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 (17) on raised areas or screw thread areas.

Abstract: A line of cotyloid implants of different sizes including a cup intended to be fastened in a cotyloid cavity and including a substantially hemispherical polar portion and an equatorial portion extending the polar portion, the polar portion and the equatorial portion delimiting a substantially hemispherical inner cavity, an insert pivotally mounted in the inner cavity delimited by the polar and equatorial portions of the cup, the insert delimiting an inner cavity having an inner spherical surface portion and intended to pivotally and retentively mount a prosthetic femoral head, where the height of the equatorial portions of the cups of the various cotyloid implants belonging to the line varies in a decreasing manner as a function of the increase in the size of the cotyloid implants.

Abstract: A subject of the invention is the use of lysyl oxidase inhibitors in the context of the implementation of in vitro cell culture methods which are capable of being used in tissue therapy, or cell therapy, or in experimental pharmacology.

Abstract: Acetabular insert comprising a spherical head arranged at one end of a medullary stem and mounted with articulation inside a core, which is itself mounted with articulation inside an acetabular component. The spherical head is made of zirconia and the core comprises an inner cup consisting of an alumina cup on which is immobilized a polyethylene cup overmolded on the alumina cup. In addition, the spherical head is configured so as to be able to be engaged without stress in the cup and be retained directly and exclusively by the latter.

Abstract: 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.
