Tibial plateau outer side bone fracture plate

Abstract

The invention provides a tibial plateau outer side bone fracture plate, and particularly relates to the field of medical instruments. The fibula fixing plate comprises a plate body, a side wing and aside hook, wherein a plurality of screw holes are formed in the plate body, the side hook capable of crossing fibula small heads is arranged at the side part of the top end of the plate body, the sidewing is arranged on the other side of the plate body, screw holes are formed in the side wing, and the side wing and the side hook are opposite in direction. The invention aims to improve the internal fixation strength of the fracture, the fracture block is better restored, and strong fixation is provided for the postoperative early functional exercise of tibial plateau fracture patients.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a tibial plateau lateral bone plate. Background technique [0002] Tibial plateau is an important load-bearing structure of the knee, and fracture of tibial plateau is one of the most common fractures in knee joint trauma. Tibial plateau fractures can be caused by indirect or direct violence. For example, when a fall occurs, the ground contact stress is transmitted upward by the foot along the tibia, and gravity is transmitted downward, and sometimes a torsional force is generated when falling to the ground. These two factors act together on the knee, resulting in the collapse and fracture of the medial or lateral platform of the tibia. Since the tibial plateau fracture is a typical intra-articular fracture, its treatment and prognosis will have a great impact on the function of the knee joint. Tibial plateau fractures are often accompanied by damage to articular cartilage, knee ...

AI Technical Summary

Problems solved by technology

The traditional anterolateral approach and suprafibular approach have less trauma and are easy to operate. Although the posterolateral bone can be effectively reset, it is difficult to fix it effectively, especially for cases with damaged posterolateral walls. Poor, early exercise can easily lead to fixation failure

Although the current anterolateral tibial plateau plate is designed to fix posterolateral plateau fragments to a certain extent, it is difficult to effectively fix smaller fracture fragments.

Moreover, in the traditional technique, the anterior-posterior screw and the row of screws are on the same plane, which may cause mutual interference of the screw implantation during the operation. In addition, the anterior-posterior screw and the rear bending part of the steel plate do not form a frame structure, and the support strength for the posterolateral bone block is greatly reduced.
