Structure Function List of Clinical Correlates Anatomical Relations The flexor retinaculum is continuous with the palmar carpal ligament. The ulnar artery and nerve and cutaneous branches of the median and ulnar nerves pass superficial to the flexor retinaculum.
The Forearm, Wrist, and Hand Musculoskeletal Key
The flexor retinaculum ( transverse carpal ligament, or anterior annular ligament) is a fibrous band on the palmar side of the hand near the wrist. It arches over the carpal bones of the hands, covering them and forming the carpal tunnel . Structure
The flexor retinaculum in the carpal tunnel consists of three segments
Definition The TCL is the middle portion of the flexor retinaculum (FR). 1 The proximal portion of the FR is the distal continuation of the antebrachial fascia. 2 The transition from the antebrachial fascia to the TCL can be identified based on gross inspection, predominantly marked by the abrupt increase in thickness.

The Palmar carpal ligament (PCL) is a distinct component of the antebrachial fascia. The distal part and the true covering of the carpal tunnel is the flexor retinaculum. There is an area in the distal part of the flexor retinaculum that consists of crisscrossing of muscle aponeurosis of the thenar and hypothenar muscles ( Fig. 18.9a,b ).

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 Wrist and Hand TeachMe Orthopedics
The carpal tunnel is a relatively small space and contains the median nerve and nine tendons that also pass from the forearm into the fingers. Most commonly, CTS results when the tendons or their lining (the synovium) thicken or the ligament tightens. The space available for the median nerve is reduced, and the median nerve becomes compressed.

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.

Flexor Retinaculum of Hand Anatomy l Surface marking l Structures
The terms transverse carpal ligament and flexor retinaculum have commonly been used to describe the fibrous structure running between the ulnar-sided hamate and pisiform bones and the radial-sided scaphoid and trapezium bones. However, the flexor retinaculum is composed of three parts. The most proximal part is continuous with the volar antebrachial fascia, the intermediate part is recognized.
Flexor Retinaculum MEDizzy
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 flexor retinaculum of the foot is a strong fibrous band that covers the tendons of the muscles that flex the foot such as walking on the toes like a ballerina.
Flexor retinaculum Physiopedia
Flexor retinaculum is a strong fibrous band which bridges the anterior concavity of the carpal bones thus converts it into a tunnel, the carpal tunnel [1]. Attachments Medially, To the pisiform bone To the hook of the hamate Laterally, To the tubercle of the scaphoid To the crest of the trapezium [1]
Flexor Retinaculum (Hand) Earth's Lab
The flexor retinaculum of foot ( laciniate ligament, internal annular ligament) is a strong fibrous band in the foot . Structure The flexor retinaculum of the foot extends from the medial malleolus above, to the calcaneus below. [1]
The Carpal Tunnel Borders Contents TeachMeAnatomy
The flexor retinaculum branches off in two places, here and here, to enclose two small, separate tunnels. This one, on the radial side, encloses the tendon of flexor carpi radialis. This one, superficial and on the ulnar side, encloses the ulnar artery and nerve. We'll be returning to the flexor retinaculum later, to look at some important.

The hamulus also serves as the attachment point for a number of different muscles and ligaments of the hand and forearm, including the flexor retinaculum. Articulations The hamate bone articulates with several adjacent bones: The proximal surface articulates with the lunate bone;
Superior Extensor Retinaculum Anatomy, Musculoskeletal system
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.
