Abstract: This fastening device comprises a bearing member intended to bear against the outer cortex of a bone and provided with a passage orifice, and a flexible connecting member configured to connect the ligament transplant to the bearing member. The connecting member comprises a tubular portion configured to extend through the passage orifice and can be deformed between a first state in which the tubular portion has a first inner diameter, and a second state in which the tubular portion has a second inner diameter smaller than the first inner diameter. The connecting member also comprises a first and a second traction portions disposed respectively on either side of the tubular portion, the tubular portion being configured to be deformed towards the second state thereof when a traction is exerted on at least one of the first and second traction portions.

Abstract: The invention relates to a cotyloid component of a hip prosthesis, said cotyloid component being hollow and in the form of a cup whose outer part has a thread allowing it to be fixed in the iliac bone, said thread being a discontinuous self-cutting double thread (20, 21), and said cotyloid component having a flattened upper pole (1), a coating that promotes osseointegration on its outer face (10), and a concave, substantially hemispherical and polished inner surface (11), characterized in that: (a) the pitch of the threads (20, 21) decreases from the upper pole (1) towards the equatorial periphery (3) of the cotyloid component, (b) the thicknesses of the threads (20, 21) increase from the upper pole (1) of the cotyloid component towards its periphery (3), (c) the crest of the threads (20, 21) is sharp towards the pole (1) of the cotyloid component and rounded or substantially trapezoidal towards the equatorial periphery (3) of the cotyloid component.
