Replacer for tibial plateau compression fracture and using method thereof

Abstract

The invention provides a replacer for tibial plateau compression fracture. The replacer comprises a variable folding replacer body, two connecting rods, a threaded main body connecting rod, a propulsion sleeve, a stopper and a holding handle. Both ends of the lower part of the variable folding replacer are movably connected to the upper ends of the connecting rods separately, and the lower ends ofthe connecting rods are movably connected with the outer surface of the upper end of the propulsion sleeve. The threaded main body connecting rod is connected into the propulsion sleeve in a sleevedmode, the stopper sleeves outside the threaded main body connecting rod, the stopper is located on the lower part of the stopper, and the lower end of the threaded main body connecting rod is connected to the upper end of the holding handle. The replacer is simple in structure, low in cost and easy to use, can increase the contact area after entering the fracture area, reduces the window range ofthe proximal tibia, increases the contact area with the fracture surface, effectively reduces the side injury brought by the reduction of the tibial plateau fracture, and creates favorable conditionsfor subsequent surgery and patient recovery.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reducer for tibial plateau compression fractures and its use. Background technique [0002] Fracture reduction is a common technique in orthopedic surgery, and it is an important method to restore fracture alignment, alignment, articular surface smoothness, and limb alignment. There are many methods of fracture reduction, including manual reduction, open reduction and so on. If the fracture involves the articular surface, surgical treatment should be performed when surgery is indicated. [0003] Compression fractures of the tibial plateau are common types of fractures. During surgical treatment, it is often necessary to reduce the compressed or collapsed articular surface, and then perform further operations such as bone graft support. So as to restore the smoothness of the articular surface and the line of force of the lower limbs. For tibial plateau compression fra...

AI Technical Summary

Problems solved by technology

Tibial plateau compression fractures are often accompanied by partial rupture of the articular surface, or rupture of the cartilage surface. If the contact surface of the instrument is small, it is easy to cause excessive contact force per unit, which may cause further rupture of the articular surface, so that the joint cavity communicates with the fracture area. Subsequent bone grafting may cause bone particles to enter the joint cavity and form loose bodies, which may further cause damage to the joint cavity, traumatic arthritis and other complications

If you want to increase the contact surface area of ​​the device, the proximal tibial window will be larger, artificially causing bone damage and loss of bone mass, which is not conducive to subsequent fracture healing and patient recovery
