NLM NIH HHS USA.gov The flexor retinaculum is a fibrous connective tissue band that forms the anterior roof of the carpal tunnel (see Image. Flexor Retinaculum of the Wrist). Many experts consider the flexor retinaculum synonymous with the transverse carpal and annular ligaments.

Flexor retinaculum Physiopedia

The roof of the carpal tunnel is formed by the flexor retinaculum (also known as transverse carpal ligament), a thick connective tissue ligament. This ligament bridges the space between the medial and lateral ends of the carpal arch, converting the arch into a tunnel. Contents Tendons of flexor digitorum profundus muscle

Causes Most commonly, a flexor tendon injury results from lacerations (cuts). A laceration to the forearm, hand or wrist can result in injury to the flexor tendons. When a flexor tendon injury happens there can be inability to bend the fingers, thumb or wrist.

Flexor & Extensor Retinaculum Musculoskeletal System Limbs (Anatomy)

The flexor retinaculum (transverse carpal ligament; anterior annular ligament) is a strong, fibrous band, which arches over the carpus, converting the deep groove on the front of the carpal bones into a tunnel, through which the Flexor tendons of the digits and the median nerve pass. It is attached, medially, to the pisiform and the hamulus of the hamate bone; laterally, to the tuberosity of.

The Carpal Tunnel Borders Contents TeachMeAnatomy

In the fingers, the flexor tendons run through osseo-fibrous tunnels formed by the annular and cruciform pulleys and covered by the flexor retinaculum. In a "trigger-finger", mechanical overuse causes thickening of the annular pulley, narrowing of the osseofibrous tunnel, and stenosing tenosynovitis of the adjacent flexor tendons (Fig. 18).

The flexor retinaculum is a strong, transverse, fibrous band that confines the flexor tendons of the five fingers, together with their synovial sheaths and the median nerve, to the arch of the carpus, which it converts into the carpal tunnel (figs. 11-2, 11-3 and 11-4 ).

The flexor retinaculum of the hand attaches to the hamate bone's hamulus, which is a curved process that lies on the bottom of the hamate bone. It connects to the middle of the pisiform, which is a small wrist bone that is shaped like a pea. In addition, it connects laterally to the scaphoid and across the middle of the trapezium.

Flexor Retinaculum Thick connective tissue which forms the roof of the carpal tunnel. Turns the carpal arch into the carpal tunnel by bridging the space between the medial and lateral parts of the arch. Spans between the hook of hamate and pisiform (medially) to the scaphoid and trapezium (laterally).

The flexor retinaculum (also known as the transverse carpal ligament ) is a rectangular-shaped fibrous band located at the volar aspect of the hand, near the wrist. Gross anatomy The flexor retinaculum encloses and forms the roof of the carpal tunnel. The ulna aspect of the flexor retinaculum forms the floor of Guyon's canal.

The Forearm, Wrist, and Hand Musculoskeletal Key

It then enters the hand deep to the flexor retinaculum, where it becomes part of the carpal tunnel. In the forearm, the median nerve gives rise to the anterior interosseus nerve, which innervates the flexor pollicis longus and the radial half of the flexor digitorum profundus. It also supplies the pronator quadratus.

Flexor Tendon Injuries are traumatic injuries to the flexor digitorum superficialis and flexor digitorum profundus tendons that can be caused by laceration or trauma. Diagnosis is made clinically by observing the resting posture of the hand to assess the digital cascade and the absence of the tenodesis effect.
