Proximal Radioulnar Articulation[edit | edit source]

The proximal radioulnar articulation is a joint located between the radius and ulna bones in the forearm. It allows for rotational movement of the forearm, enabling the hand to be turned palm up (supination) or palm down (pronation). This joint is an essential component of the complex movements performed by the forearm and wrist.

Anatomy[edit | edit source]

The proximal radioulnar articulation consists of two main components: the radial notch of the ulna and the head of the radius. The radial notch is a concave depression located on the medial side of the ulna, while the head of the radius is a rounded structure that fits into the radial notch. The joint is stabilized by several ligaments, including the annular ligament, which encircles the head of the radius and holds it in place.

Function[edit | edit source]

The primary function of the proximal radioulnar articulation is to allow for pronation and supination of the forearm. Pronation refers to the movement of the forearm that turns the palm of the hand downward, while supination refers to the movement that turns the palm upward. These movements are crucial for various activities, such as writing, typing, and grasping objects.

Clinical Significance[edit | edit source]

Injuries to the proximal radioulnar articulation can occur due to trauma or repetitive stress. Common injuries include dislocation, subluxation, and ligament tears. These injuries can cause pain, limited range of motion, and functional impairment. Treatment options may include immobilization, physical therapy, or in severe cases, surgical intervention.
