Abstract
Articular interposition implant to be placed between the articular surfaces of at least two bones separated by an articular interface to achieve arthroplasty of a joint, said implant (1) comprising immobilization means shaped so that when the immobilization means are arranged in the articular interface, the immobilization means are supportive of at least one of the articular surfaces, wherein said implant (1) extends along a longitudinal axis (X-X′) and wherein said immobilization means are shaped to prevent rotation of said implant (1) on itself with respect to said longitudinal axis (X-X′).

Articular interposition implant to be placed between articular surfaces (2A, 3A) of at least two bones (2, 3) separated by an articular interface (4) to achieve arthroplasty of a joint (5), said implant (1) comprising immobilization means (6) shaped so that when the immobilization means are arranged in the articular interface (4), the immobilization means (6) are supportive of at least one of the articular surfaces (2A, 3A), wherein said implant (1) extends along a longitudinal axis (X-X′) and wherein said immobilization means (6) are shaped to prevent rotation of said implant (1) on itself with respect to said longitudinal axis (X-X′).
Surgical method for arthroplasty by placement of an articular interposition implant between the articular surfaces (2A, 3A) of at least two bones (2, 3) separated by an articular interface (4) said method comprising the steps of:
- immobilizing the implant and positioning the implant in the articular interface (4) in such a way that it is supportive, and is immobilised through its own immobilization means (6), of at least one of the articular surfaces (2A, 3A);
- self-centering the implant by positioning the implant in the articular interface (4) in such a way that it is supportive, through its own auto-centering means (14), of at least one of the articular surfaces (2A, 3A), so as to center itself.
