Flexor retinaculum of the hand
Flexor Retinaculum of the Hand[edit | edit source]
The Flexor Retinaculum of the Hand (also known as the transverse carpal ligament) is a fibrous band on the palmar side of the hand that arches over the carpal bones. This structure forms the roof of the carpal tunnel, through which several tendons and the median nerve pass.
Structure[edit | edit source]
The flexor retinaculum is a strong, fibrous band that spans the anterior aspect of the carpal bones. It is attached medially to the pisiform and hamate bones, and laterally to the scaphoid and trapezium bones. The flexor retinaculum serves as the superior boundary of the carpal tunnel, a narrow passageway that allows the passage of the median nerve and the tendons of the flexor muscles of the hand.
Function[edit | edit source]
The primary function of the flexor retinaculum is to protect and maintain the position of the tendons of the flexor muscles during the movements of the hand and wrist. It also prevents bowstringing of the tendons, ensuring smooth and efficient movement of the fingers.
Clinical Significance[edit | edit source]
Carpal tunnel syndrome is a common condition associated with the flexor retinaculum. This condition occurs when the median nerve is compressed as it passes through the carpal tunnel, leading to symptoms such as pain, numbness, and weakness in the hand and fingers.
