INTERSOMATIC CAGE

摘要

The invention relates to an intersomatic cage comprising a body (3) and a part (2) that is designed to dilate the intersomatic space between two vertebrae (8, 8′) by rotating the cage so that the cage (1) can be inserted into the space. The body (3) has a prism shape with a substantially planar upper surface (6) which can bear against the superior vertebral endplate (8) and a substantially planar lower surface (6′) which can bear against the inferior vertebral endplate (8′).

主权项

1. An intersomatic cage system comprising:
An intersomatic cage (1) which has an essentially flat superior surface (6) capable of resting against a superior vertebra (8), an essentially flat inferior surface (6′) capable of resting against an inferior vertebra and an anterior face (7) at one end of the intersomatic cage (1) between the superior and inferior surfaces (6, 6′); and Two elongated members (13, 13′; 21, 21′) disposed in spaced-apart relationship that are fixed on the intersomatic cage (1) and protrude from the anterior face (7) and/or from the superior or inferior surface (6, 6′) of the intersomatic cage (1) or that at least a part of one of which is retractably mounted on the intersomatic cage (1) to be able to protrude from the anterior face (7) and/or from the superior or inferior surface (6, 6′) of the intersomatic cage (1), wherein said two protruding elongated members (13, 13′; 21, 21′) have outer parts that are spaced-apart by a distance greater than the distance between the superior and inferior surfaces (6, 6′) of the intersomatic cage (1) such that the two protruding spaced-apart elongated members (13, 13′; 21, 21′) are capable of expanding the intersomatic space between the two vertebrae (8, 8′) to introduce the intersomatic cage (1) in the intersomatic space when the two protruding spaced-apart elongated members (13, 13′; 21, 21′) are introduced between the two vertebrae (8, 8′).
