DRUJ is an acronym derived from the phrase "distal radioulnar joint." The DRUJ refers to the articulation point between the radius and ulna bones in the forearm, specifically at their distal ends near the wrist. This particular joint is responsible for the rotation and pivotal movements of the forearm, allowing for supination (turning the palm upwards) and pronation (turning the palm downwards).
Anatomically, the DRUJ is surrounded by a combination of soft tissues, including ligaments, tendons, and a fibrocartilaginous disc. These structures work together to maintain stability and facilitate smooth movement within the joint. Injury or damage to any of these components may result in DRUJ instability, leading to pain, difficulty rotating the forearm, and decreased functionality.
Clinical examinations and diagnostic imaging techniques, such as X-rays or magnetic resonance imaging (MRI), are utilized to evaluate the integrity and functionality of the DRUJ. Treatment options for DRUJ-related conditions range from conservative measures like splinting, physical therapy, and medications to surgical interventions, including ligament repair or reconstruction.
In summary, the DRUJ is the distal radioulnar joint responsible for forearm rotation and pivotal movements. Its complex structure involving ligaments, tendons, and a cartilaginous disc enables the joint to function properly. Understanding the anatomy and function of the DRUJ is crucial for diagnosing and managing conditions affecting this joint.
