2023年10月30日 · The floor of the carpal tunnel is formed by the carpal groove (or carpal arch), a deep arch formed by the palmar aspect of the carpal bones. This arch is bounded medially by the pisiform bone and the hook of the hamate, and laterally by the tubercles of the scaphoid and trapezium bones.

2020年11月10日 · The carpal tunnel is a narrow passageway found on the anterior portion of the wrist. It serves as the entrance to the palm for several tendons and the median nerve. In this article, we will look at the borders and contents of the carpal tunnel and its clinical significance.

The carpal tunnel is an osteofibrous canal located in the volar wrist. The boundaries are the carpal bones forming the floor, and the flexor retinaculum (or transverse carpal ligament) forming the roof (Fig. 1A).

In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand . [ 1 ]

2024年3月28日 · The carpal tunnel is a fibro-osseous canal in the anterior (volar) wrist that acts as a passageway for structures between the anterior forearm and the hand.

2024年5月15日 · Carpal tunnel syndrome is a group of symptoms that happen as a result of compression of your median nerve, which passes through the underside of your wrist. This condition can become...

2016年3月15日 · The carpal tunnel is an osseofibrous channel (a) located in the volar portion of the wrist. The floor of the tunnel is formed by the carpal bones; the roof by the flexor retinaculum (B, D: Axial T1-weighted MRI scan; C, E: ultrasound).

The dorsal floor of the carpal tunnel is abutted by the triquetrum, hamate, capitate, and the scaphoid. Radially, the scaphoid tubercle and the trapezium border the tunnel with the ulnar border being composed of the triquetrum, pisiform, and the hook of the hamate.

2016年9月25日 · Carpal tunnel is an osseofibrous space on the palmar aspect of wrist extending from distal volar wrist crease to the mid-palm, which serves as a passageway to the palm for flexor tendons and the median nerve. A. Roof: Flexor retinaculum or Transverse carpal ligament (1-3 mm thick and 3-4 cm wide)

The floor of the carpal tunnel consists of the carpal bones. The transverse carpal ligament forms the roof of the carpal tunnel and extends from the hamate and pisiform ulnarly to the trapezium and scaphoid radially.
