INTERSOMATIC IMPLANT

摘要

Disclosed is an intersomatic implant which is inserted between two consecutive bodies of vertebrae and receives an osseous graft or replacement part within the volume that said implant defines. The inventive implant comprises a cage (1), one of the lateral walls of which is open so as to define an upper branch (2) and a lower branch (3) that enter in contact with the lower end-plate of the upper body of vertebrae and the upper end-plate of the lower body of vertebrae, respectively. By default, i.e. in the absence of an external constraint, said two branches (2, 3) form a reduced convergent angle relative to the junction zones (4) thereof. Both the upper (2) and lower branch (3) are provided with an internal threading that is oriented according to the principal dimension of the branches and cooperates with a screw (12) so as to space the branches apart at a desired angle.
