The distal radioulnar joint is a pivot joint located at the wrist, where the distal ends of the radius and ulna bones meet. This joint allows for the rotation of the forearm, enabling movements such as pronation (turning the palm down) and supination (turning the palm up). This joint is crucial for various daily activities, including turning a doorknob or using a screwdriver. It is supported by ligaments that stabilize the connection between the radius and ulna, ensuring smooth movement and function of the wrist and forearm.
