摘要：
An ankle prosthesis comprising a tibial implant (1), a talar implant (2) and an insert (3) with which said implants (1, 2) are articulated, according to which: - the top face (6) of the tibial implant (1) comprises an anchoring fin (12) of the tibial implant (1), and the bottom face (15) of the tibial implant (1) is a surface articulated with the top surface (4) of the insert (3)； - the bottom face (18) of the talar implant (2) comprises means for anchoring to the talar bone, and the top face (16) of the talar implant (2) is a surface articulated with the bottom surface (5) of the insert (3), said articulation surface being saddle-shaped and comprising a longitudinal central groove (17) in which the insert (3) can move longitudinally and rotate transversely. The top face (6) of the tibial implant (1) comprises, on the anterior edge of same, a shield (7) intended to cover the lower anterior portion of the tibia, and the tibial face (8) of which is inclined and forms an angle (α) with the horizontal of between 15° and 45°, and passages (10, 11) are provided in this shield (7) for bone screws that pass through the shield (7) in an ascending manner and open on the inclined tibial face (8) of same. A kit comprising at least one such prosthesis, and indeed also a cutting guide for installing the tibial implant.Prothèse de cheville comportant un implant tibial (1), un implant talien (2) et un insert (3) sur lequel s'articulent lesdits implants (1, 2), selon laquelle : - la face supérieure (6) de l'implant tibial (1) comporte une ailette (12) d'ancrage de l'implant tibial (1), et la face inférieure (15) de l'implant tibial (1) est une surface d'articulation avec la surface supérieure (4) de l'insert (3)； - la face inférieure (18) de l'implant talien (2) comporte des moyens d'ancrage sur l'os talien, et la face supérieure (16) de l'implant talien (2) est une surface d'articulation avec la surface inférieure (5) de l'insert (3), ladite surface d'articulation étant en forme de
