Insert for cotyloidal implant, has hemispherical outer surface with centre separated with respect to centre of hemispherical inner surface along axis of revolution of outer surface in direction of opening of insert

摘要

#CMT# #/CMT# The insert (1) has a hemispherical outer surface (2) for mounting the insert in an articulated manner, where the insert is arranged in a cup (5) fixed in a cotyloidal cavity of a patient. A hemispherical inner surface (3) delimits a cavity intended to mounting of a prosthetic femoral head in an articulated manner. A centre of the surface (2) is separated with respect to centre of the surface (3) along an axis of revolution of the surface (2) in direction of an opening (9) of the insert. #CMT#USE : #/CMT# Insert for a cotyloidal implant of a hip prosthesis with double mobility (claimed). #CMT#ADVANTAGE : #/CMT# The device is placed in a position offering minimum risk of dislocation and usury of the insert. The centre of the hemispherical outer surface is separated with respect to centre of the hemispherical inner surface, thus permitting to generate voluminous contact surface, while ensuring resistance to usury. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a cotyloidal implant. 1 : Insert 2 : Hemispherical outer surface 3 : Hemispherical inner surface 5 : Cup 9 : Opening.
