Problems solved by technology

Temporary pre-bending of steel plates in other parts is still required during the operation so that they can be attached to the posterior side of the tibia, but the strength and degree of application of the steel plate after bending decrease, and the degree of firmness also decreases accordingly, which affects the therapeutic effect

Embodiment Construction

[0032] As a medical implant in the body, the present invention plays a supporting role in the collapse of the tibial plateau postcolumn caused by fracture during surgical treatment, and through the fixed support of the present invention, the platform postpost postpost can be restored to a normal structural state relationship. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0033] The present invention obtains the following data and completes the design on this basis by measuring the anatomical relationship of a large number (about 2600 cases) of the posterior side (posterior column) of the Chinese tibial plateau. The tibial plateau width is generally 75±5cm. There are two arc-shaped structures on the horizontal plane at the back of the platform. The center angle of the arc on the back inner side of the platform is 120°±15°, and the center angle of the arc on the back side of the platform is 105°±20°. The sagittal plane is ...

Abstract

The invention aims to provide a rear anatomical supporting and locking plate in the proximal tibial plateau, comprising a roughly quadrangular head with a plurality of penetrated holes and an elongated limb which is connected with the head and is provided with a plurality of penetrated holes. The invention is a novel plate developed based on the traditional plates and the AO internal fixed stent principle. The anatomical locking plate operation dispenses with prebending and massive exposure of the fracture site, minimizes injury to the soft tissues, obviously reduces the failure of implants and remarkably lowers the infection and incidence of nonunion, and bolts can be used for fixing fractures in multiple angles, thus enhancing the stability. The plate conforms to the BO internal fixation principle and has extensive application prospect and incomparable advantages with respect to complicated fracture.

Description

technical field [0001] The invention relates to a medical anatomical supporting and locking bone plate, in particular to a medial-posterior anatomical supporting and locking bone plate of the tibial proximal platform. It is used to support the collapse of the posterior column of the tibial plateau caused by fractures in surgical treatment. During the operation, the supporting locking plate is fixed to the bone with locking screws to play a supporting role, so that the posterior column of the tibial plateau can return to its normal structural state . It belongs to the technical field of medical equipment. Background technique [0002] The medical anatomical support locking plate is a fracture fixation instrument with locking threaded holes, which can fix the above plate with screws to achieve angular stabilization. The threaded holes of the locking plate can be hybrid nail holes, which can use both locking screws and traditional non-locking screws (also known as bonded plat...
