![Illustration of scapholunate interosseous ligament anatomy. The drawing depicts a slightly oblique, coronal view of the distal radius, scaphoid and lunate. The scapholunate ligament has been transected to demonstrate its three distinct parts, which include the dorsal (arrowhead), membranous (white arrow) and volar (black arrow) components[1]](/w/images/thumb/7/71/Scapholunate_interosseous_ligament_anatomy.jpeg/106px-Scapholunate_interosseous_ligament_anatomy.jpeg)
