Tibia remote end fixing device

Abstract

The invention discloses a tibia remote end fixing device including a bone fixing part capable of adhering to the tibia bone; a malleolus medialis fixing part extending from the bone fixing part in the tibia remote end direction and capable of adhering to the malleolus medialis; a fin part extending to a tibiofibula remote end joint from the malleolus medialis fixing part in the front direction of the tibia horizontally, wherein an arbitrary one of the bone fixing part, the malleolus medialis fixing part and the fin part is provided with at least one screw hole and a fixing bone nail and the malleolus medialis fixing part and the fin part can be embedded into the surface of the tibia remote end.

Description

technical field [0001] The present invention is a tibial distal fixation device, which is a bone plate, which is used for fixing the bone at the tibial distal end in ankle fracture. Background technique [0002] The tibia is located at the lower leg of the human body, and its distal end is located at the ankle of the human body. Traumatic fractures of the distal tibia can be divided into articular fractures, metaphyseal fractures, and diaphyseal fractures according to the fracture site. Fractures can be divided into Simple Fracture, Wedge Fracture, and Complex Fracture. In addition to bone fragmentation, the above fractures may be accompanied by dislocation of bone fragments. [0003] At present, for distal tibial fractures, external fixator (External Fixator) or bone plate (BonePlate) fixation device can be used. The fixation device is placed on the distal tibial fracture through surgery, and the external fixation device is fixed by screw. The fixator is combined with th...

Problems solved by technology

[0003] At present, for distal tibial fractures, external fixator (External Fixator) or bone plate (BonePlate) fixation device can be used. The fixation device is placed on the distal tibial fracture through surgery, and the external fixation device is fixed by screw. The fixator is combined with the tibia, or the bone plate is attached to the tibia and then fixed with bone nails. However, the external fixator has several disadvantages compared with the bone plate: (1) The external fixator has a large volume and must be placed on the patient's body This will cause the patient's postoperative appearance to be less beautiful and will limit the patient's movement; (2) external fixators are only suitable for specific fracture situations; (3) according to the research of Lewallen et al. (Comparison of the effects of compression plates and external fixators on early bone-healing, c66J.Bone.Joint Surg.Am.1084,1984.), the tibia after healing with external fixators has poor bone regeneration and has more holes

Third, the currently known tibial bone plate is to fix the bone nail to the screw hole of the bone plate, so that the nail cap (Cap) of the bone nail is located on the bone plate, and the nail body of the bone nail penetrates into the tibia. However, the tibia The distal end bears most of the weight of the human body. If only the nail cap of the bone nail is fixed on the bone plate to form a cantilever beam structure, the force generated at the ankle joint will deform the nail body due to the principle of leverage, and cause The plate is at risk of misalignment or deformation
