Distal Part Of The Radius, Anterior View

Description

Distal radius anatomy is centered on the flared metaphysis and the volar (anterior) surface that faces the palm. From this anterior viewpoint, the radial styloid projects distally on the lateral side, while the ulnar (sigmoid) notch lies medially, forming the radial contribution to the distal radioulnar joint. The distal articular surface for the carpal bones occupies the inferior margin, with the scaphoid facet positioned more lateral and the lunate facet more medial, separated by a subtle ridge. A broad, slightly concave anterior area supports attachment for the pronator quadratus, proximal to the articular margin. Distal radius fractures are among the most common upper limb injuries, and the relationships in this view help you judge what is at risk when the volar cortex fails or when a fragment involves the radial styloid. Volar rim and intra-articular fractures can destabilize the radiocarpal joint and the distal radioulnar joint at the sigmoid notch, a frequent source of painful forearm rotation after malreduction. Alignment matters. The anterior perspective makes the volar contour and the transition from metaphysis to articular surface easier to read, which is the part surgeons reference when planning a volar plate position and avoiding distal screw penetration into the radiocarpal joint. Use this illustration in anatomy and orthopaedic teaching blocks covering the forearm skeleton, wrist joint congruity, and surface landmarks, or in a trauma manuscript discussing Colles, Smith, and volar Barton fracture patterns and their fixation principles. It also supports exam-prep diagrams that compare carpal articulation with the scaphoid and lunate across the distal radius. Anatomical accuracy verified by SciePro's Medical Advisory Board.
