Tibia near-end outer side bone fracture plate

Abstract

The invention discloses a tibia near-end outer side bone fracture plate which comprises a bone fracture plate body, the whole bone fracture plate body tends to be in an L shape and is divided into a near tibia near-end section, a middle section and a far tibia near-end section, and near tibia upper locking holes, near tibia lower kirschner wire holes and a near tibia lower locking hole are sequentially formed in the near tibia near-end section. There are multiplenear tibia upper locking holes, the near tibia lower kirschner wire holes are arranged in the periphery of the near tibia upper locking holes, the middle section is sequentially provided with a sliding hole and a plurality of middle locking holes from left to right, a middle kirschner wire hole is formed between every two adjacent middle locking holes, and the middle kirschner wire hole is formed between every two adjacent middle locking holes. A sliding hole I, a far tibia locking hole and a far tibia kirschner wire hole are sequentially formed in the far tibia near-end section from left to right. The width and the curvature of the device are designed according to the anatomical structure of the outer side of the proximal tibia, and the device is an anatomical locking plate and can be tightly attached to the bone cortex without intraoperative shaping, so that the strength of the bone fracture plate is not reduced, and the operation time is not prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial proximal lateral bone plate. Background technique [0002] Lateral proximal tibial fractures are caused by strong trauma, resulting in comminuted proximal tibial fractures, articular surface insertion and collapse, and tibial plateau compression, easily involving surrounding tissues, blood vessels, and nerves, and accompanied by knee ligament and meniscus injuries. The fracture tissue of the proximal lateral end of the tibia is severely damaged, and joint dysfunction may remain. When the proximal lateral tibial fracture is severe, anatomical internal fixation with a bone plate is required. At present, the commonly used bone plates in the treatment of proximal lateral tibial fractures are bridge plate, angled fixation plate, universal locking compression plate, and L-shaped / golf-shaped bone plate. However, the above-mentioned bone plates have many disadvantages. ...

AI Technical Summary

Problems solved by technology

At present, the commonly used bone plates in the treatment of proximal lateral tibial fractures are bridge plate, angled fixation plate, universal locking compression plate, and L-shaped / golf-shaped bone plate. However, the above-mentioned bone plates have many disadvantages. For example, except for the universal locking compression bone plate and some L-shaped bone plates, the other bone plates are not provided with sliding holes as a whole, and the position of the bone plate cannot be fine-tuned up and down after the screw is inserted, which is not conducive to better anatomical reduction. It is not conducive to the fit of the bone and the bone plate, and increases the risk of repeated drilling and screw placement during the operation; except for the L-shaped bone plate and the angled fixed bone plate, there are no Kirschner wire holes in the body of the bone plate. When the fracture fragment is large or Complex fractures (such as comminuted fractures) cannot fix small bone fragments, which is not conducive to anatomical reduction of fractures and bone plate fixation; bone plate locking holes or combined holes are densely distributed in the body, which makes it difficult for surgeons to choose. Stress concentration increases the risk of secondary fractures; there are no grooves on the back side of the bone plate, and there are many locking nail holes. Although the fixation is stable, it affects the blood supply and easily leads to complications such as delayed union, nonunion, and wound infection.
