Definition
By Gregory R. Waryasz, MD
The distal radioulnar ligaments of the musculoskeletal system are characterized by their location and function.
They are part of the distal radioulnar joint. They consist of fibrous dense regular connective tissue of collagen fibers.
The unique structural features are that there are anterior and posterior ligaments.
The distal radioulnar ligaments as well as all other bones, muscles, and ligaments of the body are derived of mesodermal origin in the embryo.
The function of the distal radioulnar ligaments is to strengthen the joint capsule of the distal radioulnar joint.
Common diseases include ligament tears and dislocation/subluxation.
Commonly used diagnostic procedures include clinical history, physical exam, x-ray, and MRI.
It is usually treated with physical therapy and NSAIDs, but may require surgery.
