What Zone Is The Flexor Pollicis Longus Tendon In?

What zone is the flexor pollicis longus tendon in? zone TI: from flexor pollicis longus (FPL) insertion to A2 pulley.

Is flexor pollicis longus tendon in zone 2?

A feature of the flexor pollicis longus tendon injury is the frequency of palmar retraction so that a wrist approach is needed for retrieval of the proximal stump. We are reporting on our first outpatient zone T2 flexor pollicis longus tendon repair under WALANT with ultrasound guidance.

Is the thumb in Zone 2?


T1 = thumb zone 1, T2 = thumb zone 2, T3 = thumb zone 3.

What tendons are in Zone 2?

We hypothesize that a region of the flexor digitorum profundus (FDP) and flexor digitorum superficialis (FDS) tendons in zone 2 exists that, when involved in a laceration repair, will reliably catch on the A2 pulley after surgery.

What are the flexor zones?

Zone I: Extends from finger top to insertion of flexor digitorum superficialis. Zone II: This extends from insertion of flexor digitorum superficialis up to distal palmar crease. Zone III: Extends from distal palmar crease up to flexor retinaculum. Zone IV: This zone lies under flexor retinaculum.

Is the flexor pollicis longus?

The flexor pollicis longus (/ˈflɛksər ˈpɒlɪsɪs ˈlɒŋɡəs/; FPL, Latin flexor, bender; pollicis, of the thumb; longus, long) is a muscle in the forearm and hand that flexes the thumb.

Flexor pollicis longus muscle
Insertion The base of the distal phalanx of the thumb
Artery Anterior interosseous artery

Where is the abductor pollicis longus?

Abductor pollicis longus is a muscle found in the posterior compartment of the forearm. It is one of the five deep extensors in the forearm, along with the supinator, extensor pollicis brevis, extensor pollicis longus and extensor indicis.

How do you stretch the flexor pollicis longus?

Place a band around your thumb, and then move your thumb towards your little finger. Then touch your thumb to each of your fingers in turn while focusing on the flexion of your thumb. Between each finger touch you should extend your fingers and thumb fully. Repeat this ten times then switch to your other hand.

Is the flexor digitorum superficialis in Zone 2?

Background: Flexor zone II is defined as the region spanning the proximal aspect of the A1 pulley to the insertion of the flexor digitorum superficialis (FDS) tendon.

What is flexor tendon?

Flexor tendons run from the forearm to the ends of the fingers across the palm side of the hand. They control the ability to bend fingers down to the palm (for example to make a fist, grip, or pinch objects). When these tendons are cut or injured, it can be impossible to bend the fingers or thumb.

Where is zone 2 in the hand?

Zone II. Zone II extends from the middle of the middle phalanx to distal palmar crease. It contains both flexor tendon superficialis and flexor tendon profundus. Proximal to zone II, the flexor digitorum superficialis tendons lie superficial to the FDP tendons.

Why is zone 2 flexor tendon called No Man's Land?

Bunnell, in 1918, coined the term “no man's land” to describe zone 2 in the hand because at that time it was felt that no man should attempt repair within this zone.

Why is Zone 2 No Man's Land?

Zone 2 is also called as no man's land. The historic derivation of “no man's land” dates back to 14th century. It was used to describe an area outside London used for executions. Sterling Bunnel used this term in hand surgery who most probably derived it with his experience in the World War 1.

What zone is the flexor digitorum profundus?

Zone II combined flexor digitorum superficialis and flexor digitorum profundus repair distal to the A2 pulley.

What are tendon zones?

Tendon zones differ for the extensors and the flexors. For the finger flexors the zones are as follows: Zone I - distal to the flexor digitorum superficialis (FDS) Zone II - from the FDS insertion to distal portion of the A1 pulley. Zone III - from the A1 pulley to the transverse carpal ligament.

Where is the common flexor tendon?

Discussion. The common flexor tendon originates from the medial elbow and consists of pronator teres, flexor carpi radialis, palmaris longus, flexor digitorum superficialis, and flexor carpi ulnaris [5]. Degenerative enthesopathy of the common flexor tendon is far less common than that of the extensor side.

What are the attachments of the flexor pollicis longus?

Flexor pollicis longus muscle

Origin Anterior surface of radius and interosseous membrane
Insertion Palmar surface of distal phalanx of thumb
Action Metacarpophalangeal and interphalangeal joint 1; Thumb flexion
Innervation Median nerve (anterior interosseous nerve C7, C8)

Is flexor pollicis longus deep or superficial?

Flexor pollicis brevis muscle

Origin Superficial head: Flexor retinaculum, tubercle of trapezium bone Deep head: Trapezoid and capitate bones
Action Carpometacarpal and metacarpophalangeal joint 1: Thumb flexion
Innervation Superficial head: Recurrent branch of median nerve Deep head: Deep branch of ulnar nerve (C8, T1)

What nerve innervates the abductor pollicis longus?

Innervation. The abductor pollicis longus muscle is innervated by the posterior interosseous nerve, which is a continuation of the deep branch of the radial nerve after it passes through the supinator muscle.

What nerve Innervates the FPL?

Innervation of the FPL muscle is supplied by the anterior interosseous nerve (AIN), a branch of the median nerve. [7] The AIN arises from the anterolateral aspect of the median nerve immediately proximal to where the median nerve passes between the two heads of the pronator teres muscle.

Is abductor pollicis longus and extensor or flexor?

The Abductor pollicis longus (APL) is one of a deep extensor of the forearm and is responsible for facilitating movement and stabilization of the thumb. Its tendon is present in the first extensor compartment of the wrist.

What is adductor longus?

Adductor longus is one of the adductor muscles of the medial thigh. This large fan-shaped muscle is situated most anteriorly of this group and covers the middle part of adductor magnus and the anterior part of adductor brevis.

Where do you palpate flexor pollicis longus?

Palpation Assessment of the Flexor Pollicis Longus

To palpate this muscle, simply place your palpating finger pads on the radial side of the anterior, distal forearm, and ask the client to flex the distal phalanx of the thumb at the interphalangeal joint.

What is flexor carpi Radialis?

The flexor carpi radialis muscle is a long, superficial muscle of the forearm that belongs to the anterior muscle group and lies in the first layer. It is a relatively thin muscle located on the anterior part of the forearm. It arises in the humerus epicondyle, close to the wrist area.

How do you stretch extensor carpi radialis longus?

Extensor carpi radialis longus exercises

To do the stretch, hold out one hand straight and use the other hand to apply gentle pressure and bend the wrist down so that the fingers point to the ground. Hold the stretch for 30 seconds. Instead of the other hand, you can use a wall to apply pressure.

How many extensor tendon zones are there?

The dorsum of the hand, wrist, and forearm are divided into nine anatomic zones to facilitate classification and treatment of extensor tendon injuries.

What is tendon excursion?

Tendon excursion takes place as the muscle contracts and the joint rotates. The amount of tendon excursion is related to the amount of the joint rotation. A pulley-type constraint keeps the tendon path close to the bone when the tendon crosses a joint.

Where is the right flexor?

In anatomy, flexor carpi radialis is a muscle of the human forearm that acts to flex and (radially) abduct the hand. The Latin carpus means wrist; hence flexor carpi is a flexor of the wrist.
