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 () including a fixing element () including a head (A) and a pin (B) destined to be anchored in a support. The device further includes an assembly part () including a through hole (), and a ring () housed in a manner that can be oriented within the through hole (). The ring () has a passage (A) shaped so as to allow passage of the pin (B) and to stop the head (A). The ring () is expandable according to its axial direction between a configuration wherein the ring () can be oriented and a configuration wherein the ring () is blocked.

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 provides an osteosynthesis and compression screw that is self-boring and self-tapping for the purpose of coaptation of small bone fragments. The screw comprises:

Self-boring and self-tapping screw for osteosynthesis and compression

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.
