This high-detail 3D printed model presents a superficial dissection of the human hand and wrist, offering an exceptional overview of both anterior and posterior anatomical structures, including muscles, tendons, nerves, and vascular components.
Anterior View: Carpal Tunnel, Tendons & Arteries
On the anterior side, the transverse carpal and palmar carpal ligaments have been removed to expose the structures within the carpal tunnel and Canal of Guyon, including tendons and nerves. The palmar aponeurosis is also removed, revealing:
- Tendons passing through the palm
- Thenar and hypothenar muscles (mainly abductors and flexors)
- Lumbrical muscles originating from the flexor digitorum tendons
In the fingers, the fibrous tendon sheaths have been removed, clearly showing the insertions of the flexor digitorum superficialis and profundus, as well as the flexor pollicis longus tendon into the intermediate and distal phalanges.
The superficial palmar arch, formed by branches of the ulnar and radial arteries, is visible, along with its common and proper palmar digital branches reaching the fingertips. These are accompanied by the corresponding median and ulnar digital nerves.
Also preserved are the flexor carpi radialis and flexor carpi ulnaris tendons, plus the radial and ulnar arteries at the wrist.
Posterior View: Extensor Tendons & Anatomical Snuffbox
On the posterior side, the radial artery is shown in the anatomical snuffbox, giving off the deep branch (piercing the first dorsal interosseous muscle) and dorsal carpal branch.
