What is the function of flexor tendons and where do they originate?
Anatomical terms of muscle
The common flexor tendon is a tendon that attaches to the medial epicondyle of the humerus (lower part of the bone of the upper arm that is near the elbow joint). It serves as the upper attachment point for the superficial muscles of the front of the forearm: Flexor carpi ulnaris.
Where are flexor tendons?
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.
Which one is superficial to flexor tendons in hand?
The tendons to the middle and ring fingers lie superficial to the tendons of the index and little fingers, a relationship that aids in their identification during surgery.
How do you fix a flexor tendon?
Surgery will be required in order to repair the damaged tendon. A small incision is made to locate the ends of the tendon and they are then stitched back together. Flexor tendons are often difficult to get to and are located near important nerves so repair will generally occur under a general anaesthetic.
What is the common flexor origin?
The common flexor tendon originates from the medial epicondyle and the anterior joint capsule just proximal to the humeral insertion of the anterior bundle of the medial collateral ligament.
What happens if a torn flexor tendon is not repaired?
If your flexor tendons are damaged, you’ll be unable to bend 1 or more fingers. Tendon damage can also cause pain and swelling (inflammation) in your hand. Sometimes, damage to the extensor tendons can be treated without the need for surgery, using a rigid support called a splint that’s worn around the hand.
How successful is flexor tendon surgery?
Since the first flexor tendon repair was described by Kirchmayr in 1917, several approaches to flexor tendon injury have enabled successful repairs rates of 70-90%. Primary surgical repair results in better functional outcome compared to secondary repair or tendon graft surgery.
Can finger tendons heal without surgery?
A cut tendon cannot heal without surgery. Nearby nerves and blood vessels may need to be repaired as well. After surgery, the injured area will need to be moved to limit stiffness, but the repair must be protected. Tears caused by jamming injuries are usually treated with splints.
Can tendons heal naturally?
Although many minor tendon and ligament injuries heal on their own, an injury that causes severe pain or pain that does not lessen in time will require treatment. A doctor can quickly diagnose the problem and recommend an appropriate course of treatment.
