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.

  • Polymer injected arteries

  • Stand mounted

  • Human tissue with unique ID

  • Full aftersales support

Key features include

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 (not guaranteed)

  • 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

  • Open the dorsal aspect of radiocarpal joint capsule.
