Definitions

  • the invention relates to a plate that provides screw passage or attachment on the upper end of the plate and is used to fixate fractures in the upper end posterior side of the tibia.
  • the United States patent document No. US2006229621A1 which is the state of the art, discloses a bone fixation plate and a fixation plate for fixating the proximal tibia and metaphyseal tibia parts in the human or animal tibial osteotomy.
  • the United States patent document No. US448854A which is the state of the art, discloses an apparatus for osteosynthesis of fractures of the extremities of the femur. In this system, there is a piece that provides a connection between the broken bone fragments and the plate and can allow screw passage.
  • the plates used for bone fracture fixation in the art are examined, it is seen that the upper end part of the plates is rigid and inflexible and the posterior fixation of the upper end of the tibia is not possible. Besides, the plates used for bone fracture fixation in the art cannot be used in areas where fixation of upper end posterior side fractures of the tibia is difficult. Also, problems are encountered in fixation studies such as damage to critical parts such as veins and nerves. There is a need to develop the tibia proximal posterior fracture fixation plate according to the invention, in order to eliminate said problems.
  • An object of the present invention is to realize a tibia proximal posterior fracture fixation plate developed for more accurate fixation of fractures in the upper end posterior side of the tibia.
  • Another object of the present invention is to realize a tibia proximal posterior fracture fixation plate with a flexible plate upper end which can be shaped according to the bone.
  • the tibia proximal posterior fracture fixation plate realized to achieve the object of the present invention is shown in the attached figures.
  • Figure 1 Front view of the plate according to the invention.
  • FIG. 2 Side view of the plate according to the invention.
  • the parts in the figures are numbered individually, and the equivalents thereof are given below.
  • the invention relates to a plate developed for the fixation of tibia proximal posterior fractures, comprising:
  • the upper end of the tibia proximal posterior fracture fixation plate according to the invention allows more suitable bone fixation since it can be shaped according to the bone, as well as allowing bending and twisting. Also, it allows sufficient fixation of the upper end of the bone with the upper end thereof and the flexible hole I (2) and the hole II (3) on the side being made of material that can be cut when required, and by allowing delivering the locked or unlocked screws.
  • the tibia proximal posterior fracture fixation plate according to the invention can provide the posterior fixation of the upper end of the tibia using a single plate without excessive implant in areas where it is difficult to use a surgical approach.
  • the tibia proximal posterior fracture fixation plate according to the invention is designed to be inclined with an angle of approximately 100° - 120° according to the X-Y coordinate between the lower part and the upper part when viewed from the front view, and with an angle of 120° - 140° towards the front or back according to the X-Z coordinate when viewed from the side view.
  • the plate designed to be inclined has an inverted “L” shape.
  • On the plate body (1) there are 2 flexible screw holes I (2) on the short side and one flexible screw hole II (3) on the edge of the short side.
  • the plate according to the invention is designed according to the shape of the tibia posterior and thus, provides ease of use.
  • the tibia proximal posterior fracture fixation plate according to the invention is placed by making a surgical incision from the back of the knee. After the skin incision, the posterior surface of the tibia (shin-bone) is accessed by pulling the calf muscle outwards. Once the fracture ends are positioned in place, the invention prepared according to the tibia posterior surface is placed on the bone surface. Due to the inverted L design and extension of the plate, the distal corner of the posterior surface of the bone is accessed without a further surgical incision.
  • the flexible screw hole I (2) and the flexible screw hole II (3) on the plate body (1) are bent appropriately according to the bone shape and the usage requirements. Fixation screws are placed in suitable places.
