Proximal tibia fracture plate system

Abstract

The invention relates to proximal tibia fracture plate system which comprises a front outside bone fracture plate, a rear outside bone fracture plate, a rear inside bone fracture plate and an inside bone fracture plate. The proximal tibia fracture plate system has the advantages that the special bone fracture plates are designed for different directions of a tibia platform, the shape, angle and fixing length are determined in advance based on an anatomy measurement result, the reasonable screw destruction and nail entering direction are ensured, and the fixing space of the tibia platform and the structural form of the tibia are sufficiently utilized, so that the bone fracture plate corresponding to the tibia platform is exact in fixing and good in fixing effect, and bone fracture of the tibia platform can achieve anatomical reduction.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a proximal tibial bone plate system. Background technique [0002] Tibial plateau fracture is a common injury in trauma orthopedics. With the increasing number of traffic accidents, its incidence is also on the rise. Tibial plateau fractures are intra-articular fractures, which often affect the function of the knee joint due to the destruction of the articular surface of the tibial plateau. It is difficult to treat, and it is easy to leave joint dysfunction. [0003] In recent years, in order to facilitate the treatment of tibial plateau fractures, the tibial plateau has been divided into types, namely the lateral column of the tibial plateau, the medial column of the tibial plateau, and the posterior column of the tibial plateau. The bone plate used for treatment can be divided into anterolateral bone plate, posterolateral bone plate, posteromedial bone plate, and m...

AI Technical Summary

Problems solved by technology

Because tibial plateau fractures are caused by valgus of the knee joint, the articular surface of the plateau is generally a split fracture on the medial side, but the fracture line often moves from the anteromedial to the posterolateral side and often involves ligament damage. Part of the load-bearing surface is broken and collapsed, and the curative effect is not good. Traumatic arthritis, joint instability and joint dysfunction are often left behind

In the prior art, the method of using the medial bone plate with screws is usually used for treatment, but the existing medial bone plate has the following deficiencies: 1. The existing medial bone plate moves most of the fracture line towards the medial tibial plateau fracture from the anterior medial to the posterior lateral Inaccurate fixation; 2. The tibial plateau articular surface cannot achieve anatomical reduction

[0008] To sum up, there is an urgent need for a proximal tibial plate system with good anatomical shape, firm and precise fixation, which can maintain the flat tibial plateau and achieve anatomical reduction. see the report
