What muscles form the common flexor tendon?
1, 2, 3, 4 The common flexor tendon is the convergence of 5 muscles: pronator teres, flexor carpi radialis, palmaris longus, flexor digitorum superficialis, and flexor carpi ulnaris.
What is the function of flexor tendons and where do they originate?
The action of making a fist and palmar flexion of the hand involves the muscles that originate in the forearm. These muscles are called the long flexor muscles of the hand.
What does the flexor carpi digitorum do?
In anatomy, flexor carpi radialis is a muscle of the human forearm that acts to flex and (radially) abduct the hand.
How do you heal a flexor tendon?
The only effective treatment for a flexor tendon injury is to surgically repair the tendon(s) by sewing the cut ends together. Your hand surgeon will locate the ends of the tendon and stitch them back together. If the nerve has also been cut, it will be repaired at the same time.
Can a flexor tendon heal without surgery?
Because the cut ends of a tendon usually separate after an injury, a cut tendon can not heal without surgery. Your doctor will advise you on how soon surgery is needed after a flexor tendon is cut. There are many ways to repair a cut tendon, and certain types of cuts need a specific type of repair.
How long does it take for a flexor tendon to heal?
Your tendon will take up to 12 weeks to completely heal and it is important to follow all advice to avoid rupturing your tendon. Why is it important to protect my repaired tendon/s?
What is a 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.
What is the FCR tendon?
The Flexor Carpi Radialis (FCR) is one of the tendons that helps flex the wrist. It is located on the palmar surface of the wrist, near the base of the thumb muscles. Overuse, usually from repetitive lifting with the palm up, may lead to FCR Tendinitis.
What muscles are responsible for making a fist?
The abductor pollicis brevis and adductor pollicis work as antagonists to abduct and adduct the thumb respectively. Working with the flexor pollicis longus of the forearm, the flexor pollicis brevis flexes the thumb to grip objects or make a fist.
What tendon controls the middle finger?
Flexor digitorum superficialis (FDS) tendons
FDS tendons help bend the index, middle, ring, and small fingers at the middle finger joint.
What does wrist flexor mean?
Wrist flexion is the action of bending your hand down at the wrist, so that your palm faces in toward your arm. It’s part of the normal range of motion of your wrist. When your wrist flexion is normal, that means that the muscles, bones, and tendons that make up your wrist are working as they should.
What muscles are the most powerful wrist flexors?
The strongest is the flexor digitorum superficialis because it is the largest muscle cross sectionally, and it has the biggest moment arm!
What does flexor digitorum superficialis do?
The flexor digitorum superficialis flexes the middle phalanges of the medial four digits at the proximal interphalangeal joints. It also flexes the proximal phalanges at the metacarpophalangeal joints and the wrist joint. Flexor digitorum superficialis can flex each finger it serves independently.
