Magnesium alloy tibial fracture bone plate

Abstract

The invention discloses a magnesium alloy tibial fracture bone plate. The magnesium alloy tibial fracture bone plate comprises a bone plate body, which is a strip plate adapted to the length directionof the tibial body and provided with a screw hole, and the bone plate body is a curved surface adapted to the physiological structure of the tibial body in the circumferential direction of the tibialbody; the magnesium alloy tibial fracture bone plate body is a curved surface adapted to the physiological structure of the tibial body. Side wings connected to both sides of the bone plate body andhaving odd pairs, symmetrically arranged between the two side wings of each pair with respect to the length and middle section of the bone plate body; A surface of that bone plate body and the flank is for with a coating containing antibacterial agent; The median of the odd pairs of flanks fits at the fracture site. The magnesium alloy tibial fracture bonding plate according to the invention has good bonding ability with the tibia and less damage to the tibia body.

Description

technical field [0001] The invention relates to a magnesium alloy bone plate for tibia fracture. Background technique [0002] The tibia is one of the two bones of the lower leg and is located on the inner side of the lower leg. It plays an important role in supporting body weight and is the main load-bearing bone in the lower leg. It can be divided into one body and two ends. The upper end is usually called the proximal end, and the lower end is usually called the distal end. The distal end fracture is a multiple fracture, and the fracture of the backbone between the two ends is a tibial body fracture. Occurrence is rare, the bone plate of the present invention is used for tibial body fracture osteosynthesis, and the fixation of tibial fracture is mainly internal fixation. [0003] Tibial fracture itself is a multiple fracture, accounting for about 1 / 4 of the incidence of systemic fractures. At present, the internal fixation materials used clinically are mainly titanium a...

AI Technical Summary

Problems solved by technology

This type of bone plate belongs to the straight structure of the tibia, which has poor compression effect on the tibia and insufficient ability to combine with the tibia. Therefore, the number of screws used is relatively large

[0006] The bone plate disclosed in Chinese patent document CN207024109U has three types of screw holes on the bone plate in order to improve the ability to combine with the tibia, namely the first type of locking hole determined by the first locking hole and the second locking hole, and the universal locking hole. The second type of locking hole determined by the pressure hole, and the third type of locking hole determined by the pressurized combination hole, there are many types of holes, the processing is cumbersome, the cost is high, and more screws need to be adapted, which increases the damage to the tibia

Although the anti-corrosion bone plate can reduce the damage to the bone itself by placing medicine, its body structure is relatively straight, and the combination effect with the bone is not good
