Radial head, processus styloidus radii, radius fracture, wrist, elbow
Medical: radius
English: radius
The spoke is also known medically as the radius. The spoke forms with the ulna, the bones of the forearm.
Together with the carpal bones of the moonbone (os lunatum) and scaphoid bone (os naviculare / scaphoideum), the spoke forms the essential part of the wrist. Towards the elbow the spoke becomes smaller and ends with the radius head. There the radius forms the smaller part of the elbow joint (cubital joint). With the radius head (caput radii), forearm turning movements are possible. The biceps tendon (musculus biceps brachii) attaches directly above the radial head.

The Broken spoke is the most common fracture in the human body. Typically, a spoke fracture occurs when falling on the outstretched hand (extension fracture). The spoke breaks 2-3 cm above the wrist (distal radius fracture). More on this in our topic: distal radius fracture.
In addition to the distal radius fracture, there are also fractures of the spoke shaft. The radius shaft fracture in childhood is also a more common type of fracture. As a specialty in childhood, the often breaks bone, the still elastic periosteum (periosteum) remains intact. This is called a so-called Greenwood fracture.

The arrows point to the barely visible break. Only the kink (axis deviation) of the spoke is noticeable.
