Abrégé
(EN)
Disclosed is an intervertebral cage that is inserted diagonally from the posterior aspect of the body and as such can secure a normal lordosis. Said cage ensures shortened operating times and small scars and allows for surgery of reduced invasiveness that is easy on the patient. In the intervertebral cage that is inserted diagonally from the posterior side to replace damaged intervertebral discs of kyphotic lumbar vertebra and is left in place as such, the upper and lower surfaces of the main body are configured to have sloped surfaces such that the front end in the direction of insertion slopes down gradually to the back end according to the extent of the kyphosis while also forming ridges on the surfaces that extend in the transverse direction when inserted.
(FR)
L'invention concerne une cage intervertébrale qui est introduite à l'arrière de l'inclinaison du corps, et permet de cette façon de garantir une lordose normale, et qui garantit une intervention chirurgicale plus courte et une cicatrice de petite taille, permettant ainsi une intervention chirurgicale peu invasive et moins pénible pour le patient. Cette cage intervertébrale est introduite à l'arrière de l'inclinaison du corps à la place d'un disque intervertébral endommagé d'une vertèbre lombaire présentant une cyphose, et est installée à demeure de cette façon. Selon le degré de cyphose, une face supérieure et une face inférieure d'une partie principale sont mises en inclinaison, un côté extrémité arrière selon la direction d'introduction penchant davantage qu'un côté extrémité avant. En outre, une saillie se prolongeant dans une direction latérale est formée lorsqu'il y a introduction dans la surface.
(JA)
 身体の斜め後方から挿入し、その状態のままで正常なLordosysが確保できる椎間ケージであり、手術時間の短縮や傷跡の小ささを確保して患者にとって優しい低侵襲手術を可能にする椎間ケージを提供する。 後彎している腰椎の損傷した椎間板に代えて斜め後方から挿入してその状態のままで留置しておく椎間ケージにおいて、後彎程度に応じて本体部の上面及び下面を挿入方向後端側を先端側よりも漸低する傾斜面にするとともに、表面に挿入状態のときに左右方向に向延する突条を形成する。
