- TITLE Osteosynthesis plate with an anchoring hole intended to cooperate with an osteosynthesis screw for compression of two bone fragments
- the invention relates to an osteosynthesis plate comprising a plate body having a lower face and an upper face, and in which is provided at least one anchoring orifice passing through the plate body by opening into the lower face and into the the upper face, such an anchoring orifice being intended to cooperate with an osteosynthesis screw.
- anchoring orifices having a first smooth orifice region and a second partially threaded orifice region intersecting and joined by an intermediate region.
- document EP2364658 proposes an anchoring orifice having a first orifice region successively having a spherical upper section and a cylindrical lower section, and a second orifice region successively having a threaded upper section and a tapered lower section.
- a first drawback arises from the presence of a frustoconical lower section below the threaded upper section in the second orifice region, so that the thread does not extend over the entire height of the second orifice region. , to the detriment of the retention of the osteosynthesis screw in this second orifice region.
- a second drawback relates to the shape of the intermediate region which is in the form of two protruding ridges in the anchoring orifice, thus limiting the range of osteosynthesis screw diameter suitable for the anchoring orifice.
- the invention proposes to resolve all or part of the aforementioned drawbacks, by providing an anchoring orifice the shape of which allows improved retention of the osteosynthesis screw, and this for several diameters of osteosynthesis screw.
- an osteosynthesis plate comprising a plate body having a lower face and an upper face, and in which is provided at least one anchoring orifice passing through the plate body by opening into the lower face. and in the upper face, said anchoring orifice having a height main defined between the lower face and the upper face and being intended to cooperate with an osteosynthesis screw for compression and stabilization of two bone fragments, said anchoring orifice having a first orifice region and a second region of orifice intersecting and joined by an intermediate region; wherein the first orifice region has a first lower segment opening into the lower face and extending from the lower face over a first height at least equal to 90% of the main height, where this first lower segment has a generally smooth cylindrical shape and coincides with a first virtual cylinder centered on a first axis orthogonal to the lower face and having a first predefined radius;
- the second upper segment opening into the upper face and extending over a second height from the upper face, where the second upper segment has a generally smooth frustoconical or spherical shape centered on the second axis and which has a radius decreasing to starting from the upper face, starting from a large radius at the level of the upper face until reaching a small radius;
- the second lower segment extending the second upper segment, the second lower segment opening into the lower face and extending over a third height from the lower face, the second lower segment having a generally threaded cylindrical shape and coincides with a second virtual cylinder centered on the second axis and having a second radius equivalent to the small radius of the second segment greater than and greater than the first radius, said second virtual cylinder intersecting the first virtual cylinder;
- a helical rib is formed in the second upper segment and in the second lower segment to define a thread centered on the second axis, wherein said thread has an internal thread radius and an external thread radius, said internal thread radius being equivalent to the second radius so that the helical rib extends into the second lower segment over the entire third height from the lower face, said outer thread radius being less than the large radius of the second upper segment so that the rib in helix extends partly in the second upper segment without reaching the upper face; and and in which the intermediate region is formed of two planar intermediate faces extending opposite each other.
- the invention proposes to have an anchoring orifice whose primary function, when in cooperation with an osteosynthesis screw, is due to its shape of to compress and stabilize two bone fragments and, if the osteosynthesis screw is a threaded screw, to also allow this compression to be locked
- This anchoring orifice therefore has a first orifice region and a second intersecting orifice region, with different radii (the second radius being greater than the first radius) and connected by flat intermediate faces.

- This thread is made so as to extend over almost the entire height of the second orifice region, which has the advantage of solidifying the hold between the osteosynthesis screw and the plate body by increasing the surface area. contact between the thread of the screw head and that present in the second orifice region; it being noted that the second upper segment has a large radius greater than the outer radius of the thread so that this thread is not present over the entire second height of the second upper segment.
- the first virtual cylinder and the second virtual cylinder are perpendicular to the underside of the plate body, and the thread is also perpendicular to the underside of the plate body because it is concentric around the second axis, so that an osteosynthesis screw can be locked by means of a cone / cylinder wedging between the screw head and the second upper segment respectively, and this has the advantage of simplifying the manufacture and dimensional control of a plate without compromising the screw / plate locking.
- planar intermediate faces separate the first orifice region and the second orifice region, which has the advantage of being able to accept a wider range of osteosynthesis screw radius, and this without compromising the screw / interface. plate.
- these flat intermediate faces make it possible to avoid the formation of sharp edges at the intersection of the two virtual cylinders, which offers a passage between the two orifice regions of increased width (compared to a theoretical case without these faces. intermediate planes). This increase in the passage width between the orifice regions thus makes it possible to accept osteosynthesis screws whose diameters go up to this increased width, and this regardless of the positioning of the osteosynthesis screw, without conflict with sharp edges at the intersection of the two virtual cylinders.
