Anterior cruciate ligament tibia condyles spina intercondyloidea avulsion fracture fixation steel plate

Abstract

The invention discloses an anterior cruciate ligament tibia condyles spina intercondyloidea avulsion fracture fixation steel plate. The fixation steel plate is provided with a board body from a tibia condyles spina intercondyloidea front edge to anterior cruciate ligament lower end point; the end, far away from the anterior cruciate ligament lower end point, of the board body and the edges of the two sides are provided with a skirt edge along the upper surface of a tibial plateau in the periphery of the tibia condyles spina intercondyloidea in an extending mode, and the end, opposite to the anterior cruciate ligament lower end point of the skirt edge is provided with compression strips on the rear edges of the tibia condyles spina intercondyloidea respectively along the edges of the two sides of the tibia condyles spina intercondyloidea in the tibial plateau; the lower surface of the plate board is a hook face which is matched with the upper surface of the tibia condyles spina intercondyloidea which is covered by the plate board, and the skirt edge and the lower surface of compression strips are matched with the surface of the tibial plateau of the edge of the tibia condyles spina intercondyloidea; the middle portion of the plate board is provided with a screw hole, the axis of the screw hole points to cortical bone in the rear of the upper section of tibia; the tail ends of the two compression bars are provided with line tying holes respectively.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an internal fixation steel plate for bone setting. Background technique [0002] The intercondylar spine of the tibia (also known as the intercondylar ridge of the tibia) is the attachment of the inferior insertion of the anterior cruciate ligament. Avulsion fractures of the intercondylar spine are a common cause of injury to the tibial insertion of the anterior cruciate ligament; such fractures can easily lead to anterior meniscus Embedding of the horn or transverse meniscal ligaments at the fracture line interferes with fracture reduction and healing, while unreduced malunions lead to joint laxity or impingement. [0003] The modified Meyers-McKeever classification is commonly used for tibial intercondylar spine avulsion fractures: type I, no displacement; type II, anterior displacement with opening and posterior cortical hinge; type III, complete displacement, no bone connection Type ...

AI Technical Summary

Problems solved by technology

However, the above method focuses on the anterior cruciate ligament, which will undoubtedly cause damage to the anterior cruciate ligament or fracture fragments

In addition, the above methods clearly fail to fix the fragmented tibial intercondylar spine
