Abstract

Plate for the unión of fractured bones. Plate (1) for the unión of fractured bones, which has a first major surface configured to come into contact with at least part of the fractured bones, and a second major surface opposite to the first; wherein said plate (1) comprises an internal recess (5) and a plurality of holes (4) configured to allow the passage of screws therethrough, and where said screws are screwed to the fractured bones; likewise, the plate (1) comprises an oblong hole (2) through progressive self-compression, where the joining edge between the oblong hole (2) and the second larger surface has, on at least one of the sides of the contour of said edge, a concave rounding (3), guaranteeing a uniform compression of the screw with respect to the plate and associated fractured bone.

-a central core of quadrangular geometry with an internal recess (5); -two parallel branches (1a, 1b) having two holes (4) through each one respectively; where both branches (1a, 1b) are born from two of the corners of the quadrangular geometry of the central core; and -a third branch (1c) that has a single through hole (4), and that is born in a third corner of the quadrangular geometry of the central core.

Likewise, the plate (1) has, in the central core itself, two oblong holes (2) through progressive self-compression, where the joint edge between each oblong hole

(2) and the second major surface has, on at least one of the sides of the contour of said edge, a concave rounding (3). Which can be seen in detail in Figures 2 and 3.

Such concave rounding (2) of each oblong hole (2) has a variable depth, being minimal at the ends (3a) where rounding (3) is practiced, and maximum in the central area (3b) where said rounding is practiced ( 3); guaranteeing a progressive compression and maximum contact between the bone and the first major surface of the plate itself (1).

It can be seen in Figure 1, how each hole (4) belonging to the plurality of holes (4) has, in the joint edge between each hole and the second major surface, a concave rounding (4a) that has the mission of improving the distribution of pressures between the area of the plate (1) next to each hole (4) and the fractured bone itself.

In order to guarantee the deformation of the plate (1) towards the fractured bone, it is observed in figure 1 how each branch (1a, 1b, 1c) has several through holes (4), presenting a lobular geometry with respect to each hole (4) through. Being areas that adapt to the patient in a simple and ergonomic way. And in relation to said adaptability, it is described how both the cross section and the longitudinal section of said plate (1) have a concave geometry configured to adapt to the contour of said fractured bone.

As can be seen in Figure 1, the internal emptying (5) is shaped like a window in the plate and is adapted to the articular line, through which it is possible to control the evolution of the osteo-integration of the fracture or osteotomy.

This allows to fix independently the fragments of the metatarsal bones with a
