Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] like Figure 4 As shown, the present invention provides a combined posterolateral tibial plateau anatomical plate, which is composed of a bone plate body 2, a front fixation wing 4, a side fixation wing 3 and a rear baffle 1; the bone plate body 2 is The longitudinal strip-shaped plate surface, the front fixed wings 4 and the side fixed wings 3 are respectively located on both sides of the upper end of the bone plate body 2, the front fixed wings 4 and the side fixed wings 3 are integrated with the bone plate body 2, The inner surface of the anatomical steel plate composed of the bone plate body 2, the front fixed wing 4, the side fixed wing 3 and the rear baffle plate 1 matches the anatomical structure of the anterior, lateral and posterior surface of the proximal tibia; Two locking screw holes are arranged in the length direction of the front fixed ...

Abstract

The invention relates to a combined tibial plateau back outer side dissection steel plate which consists of a bone fracture plate body, a front fixed wing, a side fixed wing and a back baffle. The front fixed wing and the side fixed wing are respectively located on two sides of the upper end of the bone fracture plate body, two locking screw holes of the front fixed wing, two locking screw holes of the side fixed wing and a locking screw hole of the middle of the back baffle all face the back outer side of a tibial plateau, and the front end of the back baffle is connected with the back end ofthe side fixed wing; the back end of the back baffle is provided with two inner threaded holes consistent and matched with screws of the front fixed wing in direction; the locking screw holes of thefront fixed wing are lower than the locking screw holes of the side fixed wing for the diameter of one screw hole; the portion, located on the fibular head, of the bone fracture plate body is horizontally provided with a locking screw hole and faces the inner side of the tibial plateau. The combined tibial plateau back outer side dissection steel plate aims to overcome ripping and collapse in a back outer side area of the tibial plateau and can complete good fixation of back outer side plateau bone fracture of the tibia by a single outer side incision.

Description

technical field [0001] The invention belongs to the field of medical equipment used in orthopedic operations, and in particular relates to a steel plate for fixing fractures of the posterolateral tibial plateau. Background technique [0002] Areas on the tibial plateau such as figure 1 The division shown: with O as the center, the area of ​​AOB is the medial column, the area of ​​AOC is the lateral column, and the area of ​​BOC is the posterolateral column. Most of the fractures involve the anterolateral and posteromedial areas of the tibial plateau, and the posterolateral tibial plateau accounts for about 7 %. The mechanism of this type of fracture injury is mostly caused by the flexion of the knee joint, axial and valgus force, and the femoral condyle hitting the posterior tibial platform. The specific manifestations are simple fractures, which can also be complex fractures, involving other quadrants of the platform or accompanied by fractures of the fibular head. With ...
