Wrist

Description

Centered on the dorsal wrist of an adult Black male, the model emphasizes the bony contour of the distal radius and ulna, with the radial styloid positioned laterally and slightly distal to the ulnar styloid on the medial border. Superficial landmarks along the posterior carpal region align with the extensor retinaculum, and the dorsal wrist crease sits transverse to the carpal bones just distal to the distal radioulnar joint. From this rear oblique perspective, the lateral border hints at the thenar eminence wrapping toward the palmar side, while the ulnar side transitions into the hypothenar contour. Palpable topography matters here. The relationship between the radial styloid, Lister tubercle on the dorsal radius, and the anatomic snuffbox guides examination for scaphoid injury after a fall on an outstretched hand, when tenderness at the radial wrist can precede radiographic findings. Ulnar-sided prominence and swelling at or just distal to the ulnar styloid points clinicians toward distal radioulnar joint instability or TFCC injury, and the dorsal carpal region is the common location for ganglion cysts that can obscure these landmarks. Use this asset for musculoskeletal anatomy teaching focused on surface anatomy of the carpal region and wrist creases, or for orthopedic and hand surgery materials explaining portals for dorsal wrist arthroscopy and the safe palpation of the styloid processes in preoperative planning. It also fits clinical skills curricula where skin tone representation and reliable landmarking are needed for OSCE stations and patient education on wrist sprain versus occult fracture.
