Flexor Retinaculum (Hand) Earth's Lab

The flexor retinaculum is a strong, fibrous band that covers the carpal bones on the palmar side of the hand near the wrist. It attaches to the bones near the radius and ulna. On the ulnar side, the flexor retinaculum attaches to the pisiform bone and the hook of the hamate bone.

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.

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

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 MEDizzy

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).

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.
