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 (23) being connectable in an articulated manner by means of the calotte (9) which maybe slidably received in the recess (11)whereby D) the first and second prosthetic components (23) have a width B and a length H each being transverse to the central axis (6), said first and second prosthetic components (23) further comprise a longitudinal axis L1, respectively L2 extending parallel to the respective length Hand whereby E) the length H is greater than the width B, such that the prosthetic components (23) 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 α>0° when being projected in a plane being orthogonal to the central axis (6).一種椎骨間義體(1),特別是一個具有一中心軸(6)的椎骨間盤義體,並且包含:(A)一個具有第一貼附表面(4)和第一內側表面(7)的第一義體用元件(2),該第一貼附表面和第一內側表面係被配置成與中心軸(6)保持橫向,而且該第一義體用元件係具有一個球形凹口(11);(B)一個具有第二貼附表面(5)和第二內側表面(8)的第二義體用元件(3),該第二貼附表面和第二內側表面係被配置成與中心軸(6)保持橫向,而且該第二義體用元件係具有一個與該凹口(11)相配合的圓頂部位(9);(C)該第一義體用元件和第二義體用元件(2;3)係藉由圓頂部位(9)之作用而以一關節作動之方式相互連結,該圓頂部位(9)則是以可滑動之方式而被接收於凹口(11)內;因此(D)每一個第一義體用元件和第二義體用元件(2;3)均具有與中心軸(6)保持橫向的寬度B和長度H,該第一義體用元件和第二義體用元件(2;3)更還分別包含平行於個別不同長度H而延伸的縱軸L1、L2;以及因此該長度H係大於該寬度B,使得該二義體用元件(2;3)能夠被安置進入一個位於椎骨間空間內的位置處,其中當縱軸L1、L2突出於一個與中心軸(6)保持直交的平面時,該二縱軸L1、L2彼此相互交叉的角度α係大於0度。1...椎骨間義體2...第一義體用元件3...第二義體用元件4...第一貼附表面5...第二貼附表面6...中心軸7...第一內側表面8...第二內側表面9...圓頂部位11...球形凹口14...關節
