Fixing device for tibial plateau hyperextension fracture

Abstract

The invention discloses a fixing device for tibial plateau hyperextension fracture. The fixing device comprises a first fixing part, a second fixing part and a far-end supporting part, wherein the first fixing part is matched with anatomical characteristics of the near-end front of a tibia and used for connecting the near-end front of the tibia; the second fixing part is arranged at the inner sideor the outer side of the first fixing part and used for internal fixation of fracture of the inner side or the outer side of the tibial plateau; and the upper end of the far-end supporting part is connected with the first fixing part and the second fixing part and used for being connected with the shaft part of the tibia. According to the design of the invention, the fixing device is suitable fortibial plateau hyperextension fracture, can realize effective fixation and support of a fracture part, achieves an ideal mechanical effect, improves the treatment effect of the fracture and effectively reduces the risk of internal fixation failure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a fixation device for tibial plateau hyperextension fractures. Background technique [0002] Tibial plateau hyperextension fractures are skeletal injuries formed under special stress conditions, often manifested as tibial plateau anterior, anteromedial, and anterolateral compression fractures in varying degrees, accompanied by distraction injuries at the rear of the knee joint. The characteristics of the fracture are: bone compression; the retroversion angle of the articular surface of the proximal tibia decreases or disappears; the anterior-posterior diameter of the proximal tibia increases, etc. Therefore, the choice of treatment techniques for hyperextension fractures of the tibial plateau should meet the requirements of repairing or improving the above-mentioned injuries, that is, elevating and filling bone compression; restoring the posterior tilt and providing adequ...

AI Technical Summary

Problems solved by technology

However, the one-third tubular plate screw internal fixation technique must be combined with the ipsilateral anatomical locking plate screw technique in use. Although it has been manually bent, it cannot be guaranteed to be compatible with the anatomy of the proximal front of the tibia; Whether it is used independently or in combination, neither can provide stable and effective support, and the risk of secondary fracture displacement and internal fixation failure in the later stage is higher; The position of the screw is not easy to adjust and there is a problem of mutual infection
