The flexor pollicis longus (FPL) is a long muscle located at the deep layer with flexor digitorum profundus and pronator quadratus in the anterior compartment of the forearm. The tendon goes through the carpal tunnel and inserts on the distal phalanx of the thumb. It is the primary flexor to bend the tip of the thumb (flexion of distal

The FPL mainly flexes interphalangeal joint of the distal phalanx of the thumb. It also serves as accessory flexors of the metacarpophalangeal of the proximal phalanx and carpometacarpal joints of the first metacarpal. It may also assist in wrist joint flexion.

Flexor pollicis longus, as its name suggests, is a long muscle of the forearm. It belongs to the deep flexors of the forearm, along with flexor digitorum profundus and pronator quadratus. Since it lies in the forearm but inserts in the hand, flexor pollicis longus is also classified as an extrinsic muscle of the hand.

The flexor pollicis longus muscle inserts on the thumb at the distal phalanx. The flexor digitorum profundus muscle originates from the proximal end of the radius and ulnar. The flexor digitorum profundus muscle descends to attach at the base of distal phalanx of the second, third, fourth, and fifth digits.

Attachments and Actions of the Flexor Pollicis Longus. The flexor pollicis longus is a muscle of the anterior forearm and hand. Its principal attachments are from the anterior surface of the radius to the anterior surface of the distal phalanx of the thumb. It usually also has a small attachment to the medial epicondyle of the humerus (Figure 4) (Note: the common flexor belly/tendon of muscles.

Flexor pollicis longus is used for tasks requiring gripping of the hand such as grasping or lifting an object. Any injury to the muscle will cause a decrease in the flexion ability of the thumb which can be a frustrating and debilitating injury. Flexor pollicis longus is susceptible to muscle tears, muscle strain, tendonitis, and rupture.
