Dorsal Wrist Anatomy

Listers tubercle serves as a good landmark between compartments 2 and 3. Bones of the wrist palmar view.

Soft Tissues Of The Wrist

The distal radioulnar joint is a pivot joint located between the bones of the forearm the radius and ulna.

Dorsal wrist anatomy. Reinforced by the floor and septa of the fibrous tunnels for the six dorsal compartments see below and have a z shaped configuration. The bones comprising the wrist include the distal ends of the radius and ulna 8 carpal bones and the proximal portions of the 5 metacarpal bones see the images below. Formed by the head of the ulna and the ulnar notch of the radius this joint is separated from the radiocarpal joint by an articular disk lying between the radius and the styloid process of the ulna.

The fibres of the dorsal radiocarpal ligaments are aligned more or less in the same axis as the forearm those of. Dorsal ligaments palmar intercarpal ligaments. These two terms used in anatomy and embryology refer to back dorsal and front or belly ventral of an organism.

If talking about the skull the dorsal side is the top. The wrist also contains several soft tissues such as ligaments tendons nerves and blood vessels. It is actually a collection of multiple bones and joints.

A series of ligaments that extend transversely across the palmar front or volar surface of the wrist connecting the carpals to one another and the carpals to the radiusulna. These soft tissues function with the wrists bones and joints to provide movement sensation and nourishment to the hand. The dorsal from latin dorsum meaning back surface of an organism refers to the back or upper side of an organism.

We think this is the most useful anatomy picture that you need. The abductor pollicis longus apl and extensor pollicis brevis epb. The wrist is a complex joint that bridges the hand to the forearm.

During its examination the patients hand should rest freely or if a good access cannot be obtained it should be raised from the radial side. Dorsal wrist the hand is pronated. The dorsal wrist ligaments are comparatively thin.

A transverse sweep across the dorsal wrist is sometimes helpful identifying the extensor compartments 1 6. The first compartment of extensor tendons is localized on the radial dorsal surface of the wrist and includes the tendons of. We think this is the most useful anatomy picture that you need.
