2023年10月30日 · Based on its origin sites, flexor digitorum superficialis is divided into two heads; a humeroulnar head and radial head. Its large muscular belly courses distally towards the wrist, where it splits into four tendons and attaches to the middle phalanges of the second through fifth digits of the hand.

2022年8月10日 · 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.

2019年3月24日 · Flexor digitorum superficialis muscle weakness is associated with median nerve injury. Another common cause that can hamper FDS function is tendon injury. There are various treatment regimes based upon the causes of a decremental function of …

Flexor digitorum superficialis (flexor digitorum sublimis) or flexor digitorum communis sublimis [1] is an extrinsic flexor muscle of the fingers at the proximal interphalangeal joints. It is in the anterior compartment of the forearm.

2022年10月17日 · It contains four digital components, with a tendon that inserts onto each corresponding finger. The flexor digitorum superficialis is the primary flexor of the proximal interphalangeal (PIP) joints of the middle phalanges, but it also assists in flexion of the metacarpophalangeal (MCP) joints.

2022年8月12日 · Flexor digitorum superficialis (FDS) muscle, also known as flexor digitorum sublimis muscle, is a muscle in the second (intermediate) layer of the anterior compartment of the forearm. It splits into four tendons, passes through the carpal tunnel under the flexor retinaculum .

The flexor digitorum superficialis muscle is one of the muscles of the superficial part of anterior compartment of the forearm. It is a long, broad, fusiform type of skeletal muscle that divides into four tendons. The tendons for the middle and ring fingers lie superficial to the tendons for the index and ring fingers.

2024年11月9日 · The flexor digitorum superficialis is a muscle within the intermediate compartment of the anterior forearm. Attachments: Originates from the medial epicondyle of the humerus and the radius. The muscle splits into four tendons at the wrist, which travel through the carpal tunnel, and attach to the base of the middle phalanx of the four digits.

2025年1月21日 · Contribution to Tendon Action: The tendons of the Flexor digitorum superficialis pass under the flexor retinaculum (a strong fibrous band around the wrist) and through the carpal tunnel before inserting into the fingers. This anatomical setup allows the FDS to contribute to the overall smooth movement of the tendons, reducing friction and ...

At the level of the fingers, each flexor digitorum superficialis (FDS) tendon is volar and superficial to the flexor digitorum profundus (FDP) tendon up to the level of the distal A2 pulley, where it splits into radial and ulnar slips that rotate around the FDP tendon to become deep to the tendon.
