Common flexor tendon

Common Flexor Tendon is a tendon located in the forearm that serves as the attachment point for several muscles. It is a key component in the functioning of the hand and wrist, allowing for a wide range of movements.

Anatomy

The Common Flexor Tendon originates from the medial epicondyle of the humerus, a bony prominence on the inside of the upper arm. From there, it extends down the forearm and attaches to the bones of the hand. The muscles that attach to the Common Flexor Tendon include the flexor carpi radialis, flexor carpi ulnaris, palmaris longus, and flexor digitorum superficialis. These muscles are responsible for flexing the wrist and fingers.

Function

The primary function of the Common Flexor Tendon is to facilitate the flexion and extension of the wrist and fingers. This allows for a wide range of movements, including gripping, pinching, and manipulating objects. The tendon also plays a role in stabilizing the wrist and hand during these movements.

Clinical Significance

Injuries to the Common Flexor Tendon, such as tendonitis, can cause pain, swelling, and reduced mobility in the hand and wrist. These injuries are often caused by overuse or repetitive strain, and are common in athletes and individuals who perform repetitive tasks with their hands. Treatment typically involves rest, physical therapy, and in some cases, surgery.
