Definitions

  • the present invention relates to bone plates and bone plate kits.
  • the pull-out method is commonly used as a repair technique for medial meniscus posterior root injury (MMPRT).
  • MMPRT medial meniscus posterior root injury
  • the pull-out method involves pulling the torn end of the posterior root (PR) of the medial meniscus (MM) forward with a suture S, and reducing and fusing the torn end to the posterior root attachment of the articular surface B.
  • a bone hole H is made obliquely from the anterior surface of the tibia A to the posterior root attachment, and the suture S that is placed across the torn end is pulled forward of the tibia A through the bone hole H, and the suture S is fixed to the anterior surface of the tibia A.
  • HTO high tibial osteotomy
  • HTO is a method of correcting the tibia by cutting the tibia from the inside and enlarging the cut area.
  • a bone plate is fixed to the medial surface of the tibia with screws.
  • Bone plates for HTO include short plates (see, for example, Non-Patent Documents 1 and 2) and long plates (see, for example, Patent Document 1). Long plates are fixed to the tibia using more screws than short plates. Therefore, long plates have the advantages of being more stable in fixation and less load per screw compared to short plates.
  • the pull-out method and HTO may be performed simultaneously.
  • the screw for the bone plate does not interfere with the bone hole H for the suture S.
  • the anteriormost A screw 7a interferes with the bone hole H.
  • Fig. 10C if the position of the bone plate 1' is shifted posteriorly to avoid interference of the A screw 7a with the bone hole H, it is difficult to insert the posteriormost C screw 7c without protruding from the posterior surface of the tibia A.
  • the present invention was made in consideration of the above-mentioned circumstances, and aims to provide a bone plate and bone plate kit that allows multiple screws to be properly inserted into the bone end during simultaneous pull-out and HTO surgery.
  • One aspect of the present invention is a bone plate that is placed on the medial surface of the tibia, and is in the shape of a strip having a longitudinal direction that is aligned with the longitudinal direction of the tibia and a transverse direction that is aligned with the anterior-posterior direction of the tibia, and has a proximal side, a distal side, an anterior side, and a posterior side that correspond to the proximal side, distal side, anterior side, and posterior side of the tibia, respectively, and is provided with a first portion having a plurality of screw holes arranged in the longitudinal direction, and a second portion that is located on the proximal side of the first portion and has a plurality of screw holes arranged in the transverse direction, and among the plurality of screw holes of the second portion, the anteriormost first screw hole is located at a position offset to the distal side relative to the posteriormost second screw hole.
  • Another aspect of the present invention is a bone plate kit comprising the above-mentioned bone plate and a plurality of bone screws to be inserted into the plurality of screw holes in the second part, in which the central axes of the plurality of screw holes in the second part are inclined toward each other in a direction approaching each other as they move away from the bone plate in the direction of insertion of the bone screws, and the tips of the plurality of bone screws passing through the plurality of screw holes in the second part are positioned adjacent to or in contact with each other.
  • FIG. 1 is a diagram for explaining the Pull-out method, showing the tibia as viewed from the articular surface side.
  • FIG. 1 is a diagram for explaining the Pull-out method, showing the tibia as viewed from the inside.
  • FIG. 1 is a view of a tibia with a conventional bone plate fixed thereto, as viewed from the inside.
  • FIG. 1 is a posterior view of a tibia with a conventional bone plate fixed thereto.
  • FIG. 1 is a posterior view of a tibia with a conventional bone plate fixed thereto.
  • the bone plate 1 for HTO has been described, but the application of the bone plate 1 of this embodiment is not limited to the tibia A and HTO, and the bone plate 1 may be used for bones other than the tibia A and bone surgeries other than HTO.
