Deep structures of the wrist & hand
Product code: HP0509
-
Single Side Left or right side of a region / system / organ.
The hand is a complex and dynamic functional unit, capable of a remarkably wide range of actions from delicate and dextrous, to purposeful and powerful. It achieves this via a combination of muscles, tendons, pulleys and joint types, the ability to oppose the fingers with the thumb, and a rich sensory and motor nerve supply. This Silicone Plastinate reveals the multi-layered arrangement of muscles, tendons, arteries and nerves in the distal forearm and hand, with a focus on deeper structures. The course, branching and destination of key neurovascular structures are revealed alongside common points for their access, entrapment, damage, or local block.

Typical Features
General
- Distal forearm and hand.
- Most veins removed to provide clear views of underlying/nearby structures.
Muscles and regions
- Thumb and fingers partially abducted.
- Intermediate and deep level musculature of the distal forearm.
- Deeper views of key regions, including the carpal tunnel, ulnar (Guyon) canal, radial foveola (anatomical snuffbox) and palmar spaces.
- Boundaries of the region (site) for radiocarpal joint injection/aspiration.
- Palmar aponeurosis removed to reveal underlying structures in the palm.
- Flexor digitorum superficialis mostly removed – the distal parts of its tendons remain in the hand.
- Flexor retinaculum opened, and the deep flexor tendons and median nerve lifted out of the carpal tunnel.
- Muscles of the hand, including the lumbricals and the palmar and dorsal interossei.
- Muscles of the thenar and hypothenar eminences cut and revealed in layers.
- Pulley system of fingers opened to reveal the arrangement of the flexor tendons.
- Posterior (extensor) compartments of the wrist opened, and tendons of superficial extensor muscles reflected to reveal the tendons of deeper muscles.
- Extensor expansions of the hand, with associated attachments of the muscles of the hand.
Neurovasculature
- Most veins removed to provide clear views of underlying/nearby structures.
- Course, relations, and branches of key nerves, including the ulnar, median, and radial nerves.
- Course, relations, and branches of key arteries, including the ulnar and radial.
- Superficial and deep palmar arches and their digital branches.
- Origin, course, and relations of the digital nerves and arteries in the hand.
Possible variants or pathology
- Branching patterns of vessels, nerves, and nerve plexuses.
- Position and course of vessels and nerves.
- Tortuosity of arteries.
- Arterial aneurysm and atherosclerosis.
- Positioning of the limbs.
- Orthopaedic implants.
- Osteoarthritis and disease-related joint deformity.
- Rheumatological bone and soft tissue changes.
- Morphology and position of muscles.
- Muscle attachment points, morphology, and fibre arrangement.
- Age-related changes to muscles.
- Number and position of intertendinous connections.
Available customisations
