Problems solved by technology

Secondly, the height of the posterolateral platform of the tibia is limited, and the goal of setting two rows of nail holes on the head of the bone plate described in this invention cannot be achieved. If two rows of bone plates are set, the diameter of the nail holes is very limited, and the implantation of screws is bound to be limited. The diameter is reduced, so the fixing effect will be greatly reduced
Therefore, this invention (CN201010230592.8) does not fully conform to the actual anatomical characteristics of the posterolateral side of the tibial plateau, so it cannot provide effective fixation

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The horizontal plane described in the present invention is a section parallel to the ground; the sagittal plane refers to the section in which the osteosynthesis plate of the present invention is longitudinally cut into left and right parts along the front and back direction of the human body in the use state and is parallel to the horizontal plane; the coronal plane is Refers to the section perpendicular to the horizontal and sagittal planes.

[0025] It should be noted that, in the present invention, referring to up, down, left, and right means that the bone plate of the present invention is pressed figure 1 The orientation shown when placed.

[0026] The present invention is based on the perfect anatomical contour curve of the proximal end of the tibia, including the bone surface shape data on the rear side of the articular surface of the platform, and pro...

Abstract

The invention relates to a back outer side anatomy type locking bone fracture plate for tibia plateau. The back outer side anatomy type locking bone fracture plate for the tibia plateau comprises a horizontal part, a connecting part and a longitudinal part. Penetrating holes are formed in the horizontal part, the connecting part and the longitudinal part, the horizontal part is in a circular arc shape, a certain included angle is formed between the longitudinal part and the horizontal part, and the longitudinal part inclines towards the inner side. According to the back outer side anatomy type locking bone fracture plate for the tibia plateau, the shape which is more matched with the surface of bones is used, screws are used for locking and fixing, use is convenient, the maximum supporting fixing strength is achieved, and surgery quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a medical anatomical locking bone plate, in particular to a posterolateral anatomical locking bone plate of the tibial plateau. Background technique [0002] Tibial plateau fractures have always been a difficult point in the treatment of trauma orthopedics, especially the treatment of complex tibial plateau fractures, which has a high rate of complications and disability. Tibial plateau fractures are intra-articular fractures that require anatomical reduction and firm fixation. Especially when the posterior column bone is split or collapsed, the traditional anterior knee approach with open reduction and front-to-back internal fixation often fails to achieve the expected therapeutic effect, and is prone to secondary loss of reduction and fixation failure . In current clinical practice, more and more clinicians support the reduction of posterior column fractures of the tibi...
