Definitions
- Module for modular bone plate modular bone plate thus formed and system comprising the plate
- the present invention relates to a module for a modular bone plate.
- It also relates to a terminal module and a modular bone plate comprising a module according to the invention and a system comprising the plate according to the invention.
- 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 in terms of surgery, but must also be included; by extension and through an adapted and competitive manufacturing process and simple and attractive surgical instruments, to be integrated into a wider offer which will also have to optimize the operational impact within healthcare establishments and medical teams.
- US patent 8343 154 proposes the production of a modular bone plate to respond at least-empartie-to this drawback.
- a module for a modular bone plate having a male-type coupling coupling part, a female-type coupling coupling part, and an intermediate body extending between the male coupling part and the coupling part.
- female the intermediate body comprising a lower contact surface with the bone ⁇ and a superior surface opposite to the surface of ⁇ contacLavec-i'Osrb'encienchement - from one part to the other, locks the two modules. More specifically, the engagement between a female part and a male part of two modules is carried out in a plane substantially parallel to the mean plane of the two parts. It is understood that any effort perpendicular to the mean plane of the two parts tends to deform and potentially, in the event of intense effort, to disassemble these two parts. Furthermore, it is understood that the manufacture of such modules and their handling is not easy.

- 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.
