The invention relates to an intervertebral implant comprising: an intervertebral spacer (12) formed as a single part comprising a body (18) having a longitudinal direction, presenting in said direction an insertion first face (22) and a second face (24), and two recesses (30, 32) disposed at the ends of the body, each recess being defined by a first extension (34) extending said insertion face, by a second extension (36), and by an end wall (38); and two fastener ties (14, 16), each tie presenting a first end secured to said first extension (34) and a second end fastenable to said second face to pass around a spinous process in part and hold it in a recess. Each first extension (34) of the body has a height (h) relative to the bottom wall of the recess that is no greater than the height (h′) of the second extension that is associated therewith and that lies in the range 1 mm to 3 mm.

The invention relates to a connecting member for maintaining the spacing between at least two anchor members screwed into vertebrae. The connecting member comprises: a flexible part (10) divided into two branches (12, 14), the ends of said branches being interconnected in pairs and defining a first median plane (Pm), and two rigid rod-forming parts (20, 22) each having a fixing first portion (20′, 22′) and a second portion (20″, 22″), each of said second portions (20″, 22″) of said two rigid parts (20, 22) extending respective ends of said branches interconnected in pairs in opposite directions, so that said connecting member, whose fixing portions (20′, 22′) are fixed to respective anchor members, is able to bend elastically in a direction perpendicular to said median plane (Pm).

The invention relates to a knee prosthesis (1) including a femoral part (2) connected to a tibial plate (3) by an intermediate meniscal plate (4) provided with an upper surface (5). The intermediate meniscal plate (4) and the tibial plate (3) are connected to each other by two planar joining surfaces, the tibial plate (3) including a central pivot pin (26) or at least one clipping/indexing finger (34, 35) which protrudes with respect to the tibial joining surface (11). The meniscal joining surface (12) of the meniscal plate (4) includes, in combination, a central hole (25) capable of engaging with the pivot pin (26) of the tibial plate in one case, and a locking recess (46, 47) capable of becoming embedded with the indexing finger (34, 35) of the tibial plate in the other one case, depending on whether the tibial plate comprises a pivot pin or an indexing finger.

The invention relates to a device for locking two braids (L1, L2) in the form of tapes, the device being for fastening on a wall (S) of an element, and in particular of an intervertebral spacer. It is constituted by a body having a first face (42) for facing the wall of said element, and a second face (44). The body comprises: an axial slot (60) opening out into both faces of the body; two lateral slots (62, 64), each lateral slot opening out into both faces and having dimensions suitable for allowing one braid to pass freely; and two presser surfaces (54, 56) defined in said first face (42) of the body, each presser surface extending between one end of the body and the nearer lateral slot, a flank of each lateral slot co-operating with the associated presser surface to define a first edge (A1, A2), and the other flank of each lateral slot co-operating with the second face of the body to define a second edge (A′1, A′2).

An intervertebral implant comprising an intervertebral spacer and two fastener ties is disclosed. The intervertebral spacer may be formed having a body extending in a longitudinal direction. The intervertebral spacer may further include a first insertion face, a second face, and two recesses disposed at the ends of the body. The recesses may each be defined by a first extension, a second extension, and an end wall. Each of the two fastener ties may be secured to the first extension at a first end and a second end may be fastenable to the second face. The ties may pass around a spinous process in part and hold the spinous process within a recess. The first extension of the body may have a height relative to the bottom wall of the recess that is no greater than the height of the second extension.
