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]

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy (condition in which a nerve gets pinched) and results from compression of the median nerve in the wrist region. The median nerve provides sensation to the palm side of the thumb, index, middle, and part of the ring finger, and it supplies power to most of the thumb muscles.

1/4 Synonyms: none Intercarpal joints are all classified as synovial plane joints, meaning that the articular surfaces are functionally considered as nearly flat and lined with fibrocartilage. The joints are enclosed by the thin fibrous capsules whose internal surfaces are lined by the synovial membranes.

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 tendon sheaths of the remaining three fingers are separate. The radial bursa extends for the entire length of the flexor pollicis longus tendon and ends just proximal to the flexor retinaculum. The radial & ulnar bursa communicate at the level of the wrist joint in almost 50% of individuals. Dorsal carpal tendinous sheaths

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 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 flexor retinaculum at the ankle is formed by reinforcement of the deep fascia of the leg by transverse collagen bundles and functions to prevent 'bowstringing' of tendons as they pass the tibiotalar joint.

Definition 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.
