Radioscaphocapitate ligament

Joints and ligaments · Latin: Ligamentum radioscaphocapitatum

Open in 3D

The radioscaphocapitate ligament, together with the radiolunate, radiotriquetral form the palmar radiocarpal ligament.

This broad membranous band is attached above to the distal end of the radius, and passes downward to the scaphoid, lunate, triquetrum and capitate of the carpal bones in the wrist.

In addition to this broad membrane, there is a rounded fasciculus, superficial to the rest, which reaches from the base of the styloid process of the ulna to the lunate and triangular bones.
