What is distal radioulnar joint effusion?

Distal radioulnar joint effusion refers to the accumulation of fluid in the space around the distal radioulnar joint, which connects the radius and ulna near the wrist. This condition can result from various causes, including injury, inflammation, or underlying disease, leading to pain, swelling, and reduced range of motion in the wrist. Diagnosis typically involves imaging studies, and treatment may include rest, physical therapy, or injections, depending on the underlying cause.
