The present invention refers to a bone plate for the osteosynthesis of a fractured bone. According to an embodiment of the present invention, the bone plate comprises an upper side (101), intended to receive at least one bone screw and at least one fixation screw, and a lower side (102), intended to support itself on the bone, wherein said plate further comprises at least one pair (122) of holes (115, 116) distributed along a plane of the plate, and given that said pairs of holes (115, 116) consist of a first hole (115) intended to receive at least one bone screw, and a second hole (116) that has a thread, intended to receive at least one plate fixation screw, wherein said holes that comprise the pair (122) are tangent to each other and separated between their centers at a distance at least equal to the sum of the radiuses of said holes.
Bone Plate (100) comprising an upper plane (101), intended to receive at least one bone screw and at least one fixation screw, and a lower plane (102), intended to support itself on a bone, in which said plate comprises at least one pair (122) of holes (103-118) laid out along at least one plane of the plate (100), wherein said pair of holes (103 to 118) consists of a first hole (104, 106, 108, 110, 111, 113, 115, 117) intended to receive said at least one bone screw, and a second hole (103, 105, 107, 109, 112, 114, 116, 118) with a thread intended to receive said at least one fixation screw, characterized in that the holes of the pair (122) are tangent to each other and separated between their centers at a distance at least equal to the sum of the radiuses of said holes, and in that the thread (121) of at least one hole (103, 105, 107, 109, 112, 114, 116, 118) intended to receive a fixation screw is oriented at an angle (α) in relation to a perpendicular axis (Z) of said plate.
The Bone Plate according to one of the previous claims, wherein said thread (121) has a hyperbolic transversal profile.
The Bone Plate according to one of the previous claims, wherein said hole (104, 106, 108, 110, 111, 113, 115, 117) intended to receive the bone screw is an oblong hole.
The Bone Plate according to one of the previous claims, wherein it comprises 2 to 20 pairs of holes, particularly 6 to 16 pairs of holes.
The Bone Plate according to one of the previous claims, wherein the pairs of holes are oriented so that the holes intended to receive the bone screw (104, 106, 108, 110, 111, 113, 115, 117) are turned toward the center (119) of the plate.
The Bone Plate according to one of the previous claims, wherein the pairs of holes (122) are substantially aligned along the plane on a longitudinal axis (X) of the plate.
The Bone Plate according to one of the previous claims, wherein it comprises a chamfer (120) on its ends.
The Bone Plate according to one of the previous claims, wherein the profile of the upper (101) and lower (102) planes is curved, whose radius is comprised between approximately 10 mm and 50 mm, particularly between approximately 15 and 25 mm.
The Bone Plate according to one of the previous claims, wherein its shape is in “T” or “L”.
