摘要

Intervertebral prosthesis ( 1 ), in particular intervertebral disk prosthesis, with a central axis ( 6 ) and comprising A) a first prosthetic component ( 2 ) having a first apposition surface ( 4 ) and a first inner surface ( 7 ), both being disposed transversely to the central axis ( 6 ) and having a spherical recess ( 11 ); B) a second prosthetic component ( 3 ) having a second apposition surface ( 5 ) and a second inner surface ( 8 ) both being disposed transversely to the central axis ( 6 ) and having a calotte ( 9 ) congruent with said recess ( 11 ); C) the first and second prosthetic components ( 2;3 ) being connectable in an articulated manner by means of the calotte ( 9 ) which may be slidably received in the recess ( 11 ); whereby D) the first and second prosthetic components ( 2;3 ) have a width B and a length H each being transverse to the central axis ( 6 ), said first and second prosthetic components ( 2;3 ) further comprise a longitudinal axis LSUB1/SUB, respectively LSUB2 /SUBextending parallel to the respective length H; and whereby E) the length H is greater than the width B, such that the prosthetic components ( 2;3 ) may be put into a position in the intervertebral space in which the two longitudinal axes LSUB1 /SUBand LSUB2 /SUBintersect each other at an angle alpha0° when being projected in a plane being orthogonal to the central axis ( 6 ).
