Abstract: The invention concerns an expandable intersomatic cage (1) intended to be implanted between a first and second vertebral bodies of a patient, comprising: a cage body (2), comprising a bearing surface (6A) intended to be positioned so as to bear against the first vertebral body (4), an expansion cap (3) mounted on the cage body (2) so as to be able to pivot relative to the bearing surface (6A), said expansion cap (3) comprising an element (3A) for bearing against the second vertebral body (5), a means (16) for controlling the inclination of the expansion cap (3). said cage (1) being characterized in that the body (2) comprises at least one fastening orifice (41) forming an oblique well (42) capable of receiving and guiding from the outside of said cage (1) a means for fastening the cage (1) to the first and/or to the second vertebral body. Surgical implants.

Abstract: A vertebral implant (1) is provided to be implanted in a patient's intersomatic space. The implant (1) includes an intersomatic cage (2) and at least one fixing screw (10) that is intended to be screwed into a bony mass through a well (7) of the cage (2) to stabilize the position of the cage (2) within the intersomatic space. In addition, the well (7) and the screw (10) form a system for the self-locking of the screw (10) in the well (7) in which the screw (10) is locked into position by the well (7).
