As for this invention, each, it regards the intervertebral disk prosthetic device which possesses with the compressed pad which is laid out between the 1st and 2nd plate (3 and 4) and these plates which are installed in the vertebra which it has adjoined to the intervertebral disk which is replaced. Two installation parts (16a and 16b) to which each plate just angle of approximately 90 inclined just angle of the 50 or the 70 vis-a-vis 2nd installation means and the positive inside pages of front and back direction of the plate which include two installation parts (15a and 15b) which incline vis-a-vis 1st installation means, and the positive inside pages of front and back direction of the plate which include two installation parts (14a and 14b) which are laid out symmetrically on both sides of the positive inside pages of front and back direction of the plate is laid out symmetrically on both sides of 2nd plane surface are included, vis-a-vis the positive inside pages of front and back direction 2ndIt possesses with the 3rd installation means which are opposed to installation means.本発明は、各々が、置き換えられる椎間板に隣接している椎骨に取り付けられる第1及び第2のプレート(3、4)と、これらプレート間に配置された圧縮パッドとを具備する椎間板プロテーゼに関する。各プレートは、プレートの前後方向の正中面の両側に対称に配置された2つの取付部分(14a、14b)を含む第1の取付手段と、プレートの前後方向の正中面に対して50°ないし70°の角度だけ傾斜された2つの取付部分(15a、15b)を含む第2の取付手段と、プレートの前後方向の正中面に対して約90°の角度だけ傾斜された、第2の平面の両側に対称に配置された2つの取付部分(16a、16b)を含む、前後方向の正中面に対して第2の取付手段に対向している第3の取付手段とを有する。
