Abstract
The human hand is a grasping tool that is adaptable for performing various complex functions. The wrist is a complex joint that serves as the link between the forearm and hand and is critical for many upper extremity movements. Lower end of ulna is made up of four main parts, viz, seat, pole, fovea and styloid process. These parts play an important role in anatomy and physiology of distal radioulnar joint (DRUJ) and wrist. Any alterations in the morphometric and morphology can produce various clinical conditions like perforation of TFCC, ulnar impaction syndrome, ulnar styloid triquetral impaction syndrome. Thus the relationship of distal end of ulna with radius & ulnar carpus are important from the functional point of view.
Keywords: Lower end of Ulna, Seat, Pole, Styloid process, Distal radioulnar joint
