Language: English Polish. Ultrasound imaging of the musculoskeletal system is superior to other imaging methods in many aspects, such as multidimensional character of imaging, possibility of dynamic evaluation and precise assessment of soft tissues.
The anatomy of the hand is efficiently organized to carry out a variety of complex tasks. These tasks require a combination of intricate movements and finely controlled force production. The shape of the bony anatomy in conjunction with the arrangement of soft tissues contributes to the complex kinesiology of the hand. Injury to any of these structures can alter the overall function of the hand and therefore complicate the therapeutic management.

Wrist joint and joints of the hand Dr. Mohammed Mahmoud Mosaed 2. These muscles are assisted by the flexor digitorum superficialis, the flexor digitorum profundus, and the flexor pollicis longus. These muscles are assisted by the extensor digitorum, the extensor indicis, the extensor digiti minimi, and the extensor pollicis longus.
These muscles are assisted by the abductor pollicis longus and extensor pollicis longus and brevis. The lack of rotation is compensated for by the movements of pronation and supination of the forearm.
Important Relations of wrist joint Anteriorly: The tendons of the flexor digitorum profundus and superficialis, the flexor pollicis longus, the flexor carpi radialis, the flexor carpi ulnaris, and the median and ulnar nerves Posteriorly: The tendons of the extensor carpi ulnaris, the extensor digiti minimi, the extensor digitorum, the extensor indicis, the extensor carpi radialis longus and brevis, the extensor pollicis longus and brevis, and the abductor pollicis longus Medially: The posterior cutaneous branch of the ulnar nerve Laterally: The radial artery 8.
The joint cavity of the midcarpal joint extends not only between the two rows of carpal bones but also upward between the individual bones forming the proximal row and downward between the bones of the distal row. Ligaments They are firmly attached to the phalanx but less so to the metacarpal bone.
The palmar ligaments of the second, third, fourth, and fifth joints are united by the deep transverse metacarpal ligaments, which hold the heads of the metacarpal bones together. Each passes downward and forward from the head of the metacarpal bone to the base of the phalanx.
Interphalangeal Joints Type: Interphalangeal joints are synovial hinge joints that have a structure similar to that of the metacarpophalangeal joints. You just clipped your first slide!

The Median Nerve
Wrist Block – Landmarks and Nerve Stimulator Technique
The median nerve is derived from the medial and lateral cords of the brachial plexus. It contains fibres from roots C6-T1 and can contain fibres from C5 in some individuals. After originating from the brachial plexus in the axilla , the median nerve descends down the arm, initially lateral to the brachial artery.
The wrist block involves anesthesia of the median, ulnar, and radial nerves, including the dorsal sensory branch of the ulnar nerve. The wrist block is simple to perform, essentially devoid of systemic complications, and highly effective for a variety of procedures on the hand and fingers.
