[0003] The utility model aims to provide a locking distal tibia posterolateral bone fracture plate, which is designed with a variety of humanized designs to make the product more adaptable to the actual needs of customers.
[0004] An embodiment of the present application discloses a locking distal posterolateral tibia bone fracture plate, comprising a strip-shaped main plate body, the head of the strip-shaped main plate body protrudes outward to form a palmar plate body, the bottom surface of the palmar plate body is concave inward to form an anatomical concave surface that fits the bone surface, a wedge-shaped plate is formed at the tail of the strip-shaped main plate body, a plurality of compression screw holes are arranged on the surface of the strip-shaped main plate body along its extension direction, a long screw hole is formed in the middle of the strip-shaped main plate body, and a plurality of universal screw holes are arranged on the surface of the palmar plate body.
[0005] Preferably, in the above-mentioned locking posterolateral distal tibia bone fracture plate, a blood supply groove perpendicular to the extension direction of the strip main plate body is formed on the back side of the strip main plate body between two adjacent compression screw holes.
[0006] Preferably, in the above-mentioned locking posterolateral distal tibia bone plate, the adjustment range of the universal screw hole is ±15°.
[0007] Preferably, in the above-mentioned locking posterolateral distal tibia bone plate, shaping grooves are formed on both sides of the strip-shaped main plate body between two adjacent compression screw holes.
[0008] Preferably, in the above-mentioned locking posterolateral distal tibia bone fracture plate, Kirschner wire holes are formed on the palmar plate body, the wedge plate and the strip-shaped main plate body respectively.
[0009] Compared with the existing technology, the advantages of this technical solution are that the anatomical concave surface of the palm plate fits the bone surface better and the effect is better; the wedge-shaped plate facilitates implantation; the compression screw facilitates pressure, making the disconnected bone surface closer; the long screw hole facilitates position adjustment during surgery; the universal screw hole can be adjusted within ±15°, which facilitates the adjustment of the screw insertion direction; the blood supply groove is conducive to blood supply and promotes bone healing; the shaping groove facilitates shaping.
