Tibia medial plateau bone fracture plate

Abstract

The invention discloses a tibia medial plateau bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is divided into a far plateau section, a middle section and a near plateau section, and the near plateau section is of an arc-shaped structure and a slope structure. The near plateau section is sequentially provided with a near-plateau upper kirschner wire hole, a near-plateau upper locking hole, a near plateau lower kirschner wire hole and a near plateau lower locking hole from left to right, the middle section is in a plane design and accords with a tibia backbone anatomical structure, the middle section is sequentially provided with a sliding hole and a plurality of middle locking holes from left to right,. A middle Kirschner wire hole is formed between every two adjacent middle locking holes, and the far platform section is sequentially provided with a sliding hole I, a far platform locking hole and a far platform Kirschner wire hole from left to right. The width and the curvature are designed according to an anatomical structure of a tibia medial platform, and the device is an anatomical locking plate and can be tightly attached to bone cortex without intraoperative shaping, so that the strength of the bone fracture plate cannot be reduced, and the operation time cannot be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial medial platform bone plate. Background technique [0002] The medial tibial plateau fracture is a fracture caused by violence on the contact surface between the tibia and the lower end of the femur. The tibial plateau is an important load-bearing structure of the knee. Once a fracture occurs, the force on the inner and outer platforms will be uneven, and osteoarthritis will easily occur over time. Medial tibial plateau fractures are common in adolescents and can easily lead to meniscal injury and cruciate ligament injury. In severe cases, bone plate reduction and fixation surgery will be used. The commonly used bone plates in the treatment of medial tibial plateau fractures are dynamic compression DTS bone plate and anatomical bone plate, but the existing dynamic compression DTS bone plate and anatomical bone plate have many shortcomings, for example: dynamic co...

AI Technical Summary

Problems solved by technology

The commonly used bone plates in the treatment of medial tibial plateau fractures are dynamic compression DTS bone plate and anatomical bone plate, but the existing dynamic compression DTS bone plate and anatomical bone plate have many shortcomings, for example: dynamic compression DTS bone plate There are no multiple locking holes in the head of the plate. When the fracture fragment is large, it cannot be stably fixed, and the fracture end is easy to shift. It needs to be combined with other bone plates to assist in the fixation.

The screw holes in the plate body are densely distributed. Although the internal fixation can be strong to a certain extent, it is easy to cause stress concentration, which makes it difficult for the operator to choose.

There are no grooves on the back side of the bone plate, and there are many locking nail holes. Although the fixation is stable, it affects the blood supply, which may easily lead to complications such as delayed union, nonunion, and wound infection.

There are no Kirschner wire holes in the body of the plate, and small bone fragments cannot be fixed, especially when the fracture area is large or complex fractures; the anatomical bone plate has no Kirschner wire holes in the body, and small bone fragments cannot be fixed when there are many fracture fragments or complex fractures , not conducive to fracture anatomical reduction and bone plate fixation

There is no Kirschner wire hole at the distal end of the plate, and the distal end tends to warp and not fit the bone surface when fixing the proximal end of the bone plate, which is not conducive to the temporary fixation of the distal end and the determination of the bone plate position

Except for the T-shaped and L-shaped bone plates, there are no sliding holes in the body or distal end of the other bone plates, which cannot fine-tune the bone up and down. Risk of repeated drilling and nailing
