Tibial plateau posterolateral bone fracture plate for fracture at attachment of posterior cruciate ligament

Abstract

The invention provides a tibial plateau posterolateral bone fracture plate for a fracture at the attachment of the posterior cruciate ligament, which belongs to the field of medical devices. The tibial plateau posterolateral bone fracture plate comprises a handle-like part which is in adaptation with the proximal tibia posterior metaphysic, a main support plate part which is in adaptation with the tibia posterolateral articular lip and a side support part covering the bone surface at the attachment of the posterior cruciate ligament, wherein the front end of the handle-like is connected with the main support plate for constituting a T-shaped or L-shaped bone fracture plate whole, the bone fracture plate whole comprises a bottom side surface for being in contact with the bone and a group of screw holes, the handle-like part of the bone fracture part has a certain radian so as to enable the bone fracture plate to be completely attached on the posterior column of the tibial plateau and enable the main support plate part to be attached on the posterior lateral margin of the tibial plateau, and the side support plate part is covered on the bone surface at the attachment of the posterior cruciate. The embodiment of the invention is suitable for treatment of complex tibial plateau fractures, in particular to the fractures at the attachment of the posterior cruciate ligament, and can enable the fracture to heal better.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a posterolateral tibial plateau bone plate used for fractures at the insertion point of the posterior cruciate ligament. Background technique [0002] In the prior art, when treating tibial plateau fractures, bone plates are generally used to fix the main body of the tibia on the front side of the tibia. In recent years, the three-column theory of the tibial plateau has emerged, and clinicians have begun to emphasize direct reduction and support for posterior column fractures. At present, there are also techniques that pay attention to the application of posteromedial or posterolateral locking anatomical plates for support and fixation. However, these technical means have not paid attention to the treatment of the bone fragments at the insertion point of the posterior cruciate ligament involved in the treatment of complex tibial plateau fractures. In the prior art, there has not b...

Problems solved by technology

However, these technical means have not paid attention to the treatment of the bone fragments at the insertion point of the posterior cruciate ligament involved in the treatment of complex tibial plateau fractures. In the prior art, there has not been a special bone plate for fixing complex fractures involving the insertion point of the posterior furrow ligament, which has affected healing of the fracture
