Anterior Border Of The Radius, Anterior View

Description

Radius anatomy is centered on the margo anterior, a sharp ridge that runs distally from the radial tuberosity toward the radial styloid process in an anterior (front) view of the forearm bone. Proximally, the tuberosity sits on the anteromedial aspect just distal to the neck, and the anterior border descends along the shaft as a crisp line separating the anterior surface from the lateral surface. Distally, the ridge approaches the styloid region while the broad distal radius flares to form the carpal articular surface, with the radial styloid positioned lateral to the ulnar notch. Edges are the story here. Clinically, the anterior border helps orient the surgeon and trainee to the volar (palmar) side of the radius when planning approaches for distal radius fracture fixation and corrective osteotomy, where plate placement and screw trajectories must respect the distal radial anatomy. Its relationship to the anterior surface matters for understanding the origin area of flexor pollicis longus and the adjacent interosseous membrane, structures implicated in complications such as flexor tendon irritation after volar plating. The fixed anterior perspective keeps proximal landmarks (head, neck, tuberosity) and the distal styloid alignment in a single frame, which is exactly what you need when teaching bony orientation before moving on to soft tissue layers. Use this illustration in upper-limb osteology labs, orthopaedic surgery teaching files, and medical publishing layouts that describe surface borders and named bony landmarks of the radius in standard anatomical position. It also supports exam-prep figures that ask learners to trace the anterior border from the radial tuberosity to the styloid process without confusing it with the interosseous (medial) border.
