värttinäluun

Värttinäluun is a Finnish word that translates to "radius" in English. The radius is one of the two long bones in the forearm, located on the thumb side. It runs parallel to the ulna, the other forearm bone. The radius is essential for forearm rotation, allowing movements like pronation (turning the palm down) and supination (turning the palm up).

The radius articulates with the humerus at the elbow, forming part of the elbow joint. It also connects with the ulna at both its upper and lower ends via the radioulnar joints. At the wrist, the distal end of the radius articulates with the carpal bones, forming the wrist joint. This articulation is crucial for the hand's movement and grasp.

Fractures of the radius are common injuries, often occurring due to falls on an outstretched hand. The location and severity of the fracture can vary, impacting the function of the forearm and wrist. Treatment typically involves immobilization, such as casting or splinting, and in more severe cases, surgical intervention may be necessary to ensure proper alignment and healing. The radius plays a vital role in the overall functionality of the upper limb.
