Definitions
- the present invention relates to a modular bone plate module arranged to receive an anchoring device.
- It also relates to a modular bone plate comprising a module according to the invention and a system comprising the plate and the anchoring device.
- the field of the invention is that of bone plates suitable for being used to perform osteosynthesis.
- the field of the invention is more particularly that of modular bone plates for the treatment of fractures or osteotomies affecting the skeletal system.
- compression plates are therefore positioned against the periosteal surface of the bones to be treated, their design and dimensioning being closely linked to two factors: on the one hand the patient's bone anatomy and on the other hand the nature and the location of the fracture or osteotomy.
- the modularity of the osteosynthesis systems, and more particularly of the plates, is therefore a solution to better meet the expectations of practitioners on the surgical level, but must also allow, by extension and through an adapted and competitive manufacturing process and surgical instruments simple and attractive, to be integrated into a broader offer which will also have to optimize the operational impact within health establishments and medical teams.

- the third family of components does not have the effect of locking a first module on a second module, but only of preventing the compression screw from being extracted from the bone in which it is screwed.
