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]


Wrist Joint AnatomyBones, Movements, Ligaments, Tendons Abduction

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.


Strained Flexor Retinaculum of the Foot

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


Anatomy and Functional Anatomy of the Hand Plastic Surgery Key

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 ( 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

Flexor retinaculum (Retinaculum flexorum) Kenhub

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.


Superior Extensor Retinaculum Anatomy, Musculoskeletal system

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]


The flexor retinaculum in the carpal tunnel consists of three segments

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.


The flexor retinaculum of Hand Gross anatomy , Attachments and

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.


Flexor Retinaculum (Hand) Earth's Lab

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.


Flexor retinaculum Physiopedia

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;
