Therefore, in some cases, each other in fracture formation. they affect. In addition, the radius and ulna are the mobile and small parts of the human body. It connects the wrist structure, which consists of bones, to the body. Wrist in the process of fracture treatment Continuing the movement is an important point.

The distal metaphysis of the radius has a cancellous structure. In addition, a large number of distal radius bag joint (ligamen) is available. These usually occur during distal radius fracture. remains intact and facilitates reduction. This concept is known as ligamentotaxis. is named.

Fractures can be caused by falls from height, motor vehicle accidents and athletic sports in young individuals. While it is seen during participation, in elderly individuals, standing and a similar simple decrease is observed. may be caused by low-energy mechanisms such as Most common injury form occurs by falling on the hand while the wrist is in dorsiflexion. Usually distal Radial fractures are produced when the dorsiflexion of the wrist changes between 40 and 90 degrees.

As the fracture progresses dorsally, the bending force causes compression stresses. is happening. This causes dorsal fragmentation. The spangle structure of the metaphysis is stable is not sufficient and shear forces may affect the injury pattern.

Therefore, the fracture can also spread to the joint surface. high energy injuries (vehicle traumas) significantly displaced in distal diameter or very fragmented unstable can cause cracks.

Closed surgeries for wrist (distal radius) fractures are currently available with two classical methods. is applied. These are applied with closed Kirsehner wires after closed reduction in simple fractures. Ligamentotaxis with external fixator in percutaneous pinning and complex comminuted fractures are methods.
