What is mannerfelt syndrome?

Mannerfelt syndrome refers to rupture of the flexor pollicis longus (FPL) tendon from attrition caused by a bony spur in the carpal tunnel. Such ruptures were described by multiple authors from 1891 on.

What is flexor pollicis longus?

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. Though it is situated at the forearm, it is classified as part of the extrinsic muscles of the hand as it’s function is seen in thumb movement.

What is flexor pollicis longus tendon rupture?

Flexor pollicis longus (FPL) tendon rupture is a major complication of volar locking plate fixation for distal radius fractures. The tendon rupture is usually caused by friction between the distal edge of the plate and the FPL tendon, and has been well detected recently with ultrasonography.

What is a Pseudotendon?

The biologic reconstitution of a divided flexor tendon by scar tissue forming a “pseudotendon” is described in three cases. With close inspection, one is able to differentiate a pseudotendon from a normal tendon intraoperatively by its relatively light gray color and the lack of a glistening surface.

How do you stretch the flexor pollicis longus?

The Flexor Pollicis Longus is a flexor of the thumb, so to stretch it, we will be creating an opposing action. Place your forearm on a table with the palm facing down. Using two fingers, extend the thumb and try to pull it towards you slowly. You will feel the stretch.

What causes pain in the flexor pollicis brevis?

Injuries to flexor pollicis brevis can include strain, tears, atrophy, infectious myositis, and overuse. Injury should be suspected when hand or thumb pain is present or if there is decreased flexion of the thumb.

How do you treat a flexor tendon injury?

Flexor tendon injuries do not heal by themselves and frequently require surgery to put the injured tendon back to its normal position. When surgery is required, a splint and hand therapy may be used after the procedure to protect you and to aid in recovery.

What is palmaris longus?

The palmaris longus belongs to the anterior forearm flexor group in the human upper extremity. The muscle attaches proximally to the medial humeral epicondyle and distally to the palmar aponeurosis and flexor retinaculum.

Where is the flexor digitorum?

forearm
Flexor digitorum profundus is a fusiform muscle located deep within the anterior (flexor) compartment of the forearm. Along with the flexor pollicis longus and pronator quadratus muscles, it comprises the deep flexor compartment of the forearm.

What is Banti syndrome?

Banti syndrome is a disorder of the spleen, the large, gland-like organ in the upper left side of the abdomen that produces red blood cells before birth and, in newborns, removes and destroys aged red blood cells, and plays a role in fighting infection.

Why does my Pollicis hurt?

Pain in the adductor pollicis can occur due to osteoarthritis, soft-tissue trauma in the hand or excessive strain. One condition which can affect the adductor pollicis and thumb adduction is the gamekeeper’s thumb, in which the ulnar collateral ligament above the adductor pollicis is overly strained.

Does flexor pollicis longus go through carpal tunnel?

The carpal tunnel contains nine tendons: the flexor pollicis longus, the four flexor digitorum superficialis and the four flexor digitorum profundus as well as the median nerve (B, C).

Why is the base of my thumb so painful?

Pain at the base of your thumb This pain could be a symptom of thumb injury or overuse, basal joint arthritis, or carpal tunnel syndrome. Additionally, pain at the base of your thumb can be caused by injuries to the ligaments at the lower part of your hand and in your wrist.

What Innervates loaf muscles?

All the intrinsic muscles of the hand are innervated by the ulnar nerve, except four muscles which are supplied by the median nerve and are easily recalled with the mnemonic: FOAL or LOAF.
