Palmar radiocarpal ligament
The palmar radiocarpal ligament, also known as the anterior ligament, volar radiocarpal ligament, is a broad membranous band attached above to the anterior margin of the lower end of the radius and to the front of the lower end of the ulna. The ligament’s fibers pass downward and medialward to be inserted into the volar surfaces of the scaphoid, lunate, and triangular bones; some of the fibers continue on to the capitate.
The palmar radiocarpal ligament is perforated by apertures for the passage of vessels. It is located in relation, in front, with the tendons of the Flexor digitorum profundus and Flexor pollicis longus. And behind, it is closely adherent to the anterior border of the articular disk of the distal radioulnar
Sometimes the components of the ligament are broken down into sub-ligaments: radiolunate, radiocapitate, radiotriquetral, and radioscaphoid. Other sources combine the radioscaphoid and radiocapitate into the “radioscaphocapitate.”
