Abstract: Arthrodesis apparatus for first and second bones (2, 3), comprising a nail (5) and an instrument (20) for putting the nail (5) into place, the instrument comprising a base (21) and compression means (22, 23) comprising control means (22) for causing the nail to move relative to the base (21) and holder means (23) for holding the second bone (3) relative to the base (21); a guide (11) for the nail, the guide (11) and the holder (23) being arranged and shaped to cooperate together in such a manner to as allow the nail to move relative to the holder (23) and move the first bone (2) and the second bone (3) towards each other.

Abstract: The invention relates to an ankle prosthesis including a talar implant, a tibial implant, and an intermediate implant designed to be mounted to move relative to said talar implant in order to impart mobility to the ankle, said prosthesis further including embedded adjustment structure designed to alternate between a releasing state, in which they allow the intermediate implant to move relative to the tibial implant, and a locking state, in which they hold the prosthesis in the chosen assembly configuration, said prosthesis being characterized in that said adjustment structure can be controlled to be operable while the prosthesis is in the assembled state in vivo.

Abstract: Disclosed herein is a device destined to be coupled to at least one support, and in particular a surgical implant destined to be coupled to a bone. The invention relates generally to a device (1) including a fixing element (3) including a head (3A) and a pin (3B) destined to be anchored in a support. The device further includes an assembly part (4) including a through hole (5), and a ring (6) housed in a manner that can be oriented within the through hole (5). The ring (6) has a passage (6A) shaped so as to allow passage of the pin (3B) and to stop the head (3A). The ring (6) is expandable according to its axial direction between a configuration wherein the ring (6) can be oriented and a configuration wherein the ring (6) is blocked.

Abstract: An ancillary device for positioning a bone graft between bones separated by an articular slot, to ensure arthrodesis of a joint, wherein the bone graft is placed in a recess provided at the end of one or more bones defining the articular slot, and comprising means for driving the bone graft, provided with support means on the bone graft suitable for moving the latter in the recess, and actuation means, functionally connected to the driving means, and capable of being handled in order to control the movement of the bone graft.

Abstract: A medical implant interposable between a first bone and a second bone in order to support the first and second bones substantially joined one to the other, so as to obtain bony fusion of the first and second bones. Also disclosed is a surgical kit comprising an implant and a surgical instrument for bony preparation. Also disclosed is a method for manufacturing a medical implant.

Abstract: An osteosynthesis screw comprising both a screw shank, having a thread with a distal zone and a proximal zone, and a screw head for threading on the screw shank and for co-operating with its proximal zone via internal tapping complementary to the thread of the shank is suitable for applying compression to bone fragments. The screw head also has an outside thread at a pitch that is smaller than the pitch of the screw shank, wherein the distal zone and the proximal zone are separated by a central zone shaped to be inactive during screwing so as to form a sliding zone for the bone fragments to be put into compression.
