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.
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.
How many flexor tendon zones are there?
Flexor tendons of hand are divided into five 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.
Is the flexor digitorum superficialis in Zone 2?
Strength and functional recovery following repair of flexor digitorum superficialis in zone 2.
What zone is flexor pollicis longus?
Zone II Flexor Pollicis Longus Repair: Thumb Flexion and Complications.
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 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.
Why is Flexor Zone 2 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.
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 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. After surgery, the hand is placed in a dorsal, extension blocking splint with the wrist at 20° to 30° flexion for approximately 2.5 weeks.
What is the flexor pollicis longus tendon?
It is the most radial tendon in the carpal tunnel. The tendon passes under the transverse carpal ligament and around the hook of the distal scaphoid, and it inserts into the base of the distal phalanx of the thumb, flexing the distal phalanx. The anterior interosseous branch of the median nerve supplies the FPL.
What type of muscle is flexor pollicis longus?
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.
