Posterior Full Body View Of The Radius

Description

Seen from the posterior aspect in anatomical position, the full male skeleton is presented with the radius and ulna of the forearm highlighted against the axial framework of the cranium, vertebral column, thoracic cage, and pelvis. At the distal radius, the dorsal tubercle (Lister’s tubercle) is identifiable on the dorsum of the wrist, positioned just proximal to the radiocarpal joint and lateral to the distal ulna. Proximally, the radius lies lateral to the ulna along the forearm, continuing to the radial head at the elbow, while the scapulae, humeri, and hand skeleton provide clear upper limb orientation. Clean bony landmarks. Posterior emphasis matters here because Lister’s tubercle is a palpable, surgically relevant ridge that functions as a pulley for the extensor pollicis longus tendon as it courses obliquely toward the thumb. This is the landmark used to distinguish extensor compartments at the dorsal wrist and to guide dorsal approaches, including portal placement in wrist arthroscopy and planning for distal radius fracture fixation. It also anchors clinical teaching around extensor pollicis longus attrition and delayed rupture after distal radius fractures, where dorsal callus or hardware prominence can compromise the tendon. Use this asset for upper limb anatomy lectures on the radius and ulna, for teaching cross sectional relationships of dorsal wrist extensor compartments, and for orthopaedic or hand surgery materials discussing distal radius fractures, dorsal wrist pain, and extensor tendon complications. It also fits well in patient education handouts that need a clean posterior skeletal reference to explain where the radius sits relative to the ulna at the wrist and elbow.
