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 L1, respectively L2 extending 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 L1 and L2 intersect each other at an angle E > 0° when being projected in a plane being orthogonal to the central axis (6).
