Hence we advocate the repair of palmaris longus tendon when it is divided. The repair should be considered if the cut is single and at the wrist or at the musculotendinous junction. Once the tendon is cut, the muscle will retract and the tendon may curl up ending in a mass which will be unusable later.

The absence of palmaris longus muscle (PLM) has been reported not to affect grip strength and pinch strength [11]. The prevalence of the absence of the palmaris longus tendon is around 15 % according to the standard textbooks but widely varies in different populations and ethnic groups.

The role of this muscle is to help with wrist flexion. The palmaris longus muscle is one of the most variable muscles of the body. Although in the upper limbs its function is considered insignificant, in the event of tendon grafting, it is considerably important.

Reversed palmaris longus muscle was found in 2 forearms in two foetuses. Long muscular belly and short tendon of palmaris longus muscle was observed in one of 24 foetuses but in both forearms [16].

Abstract. The palmaris longus tendon is the most frequently harvested tendon for reconstructive plastic and hand surgical procedures. This study demonstrates that absence of the palmaris longus is not associated with a decrease of grip or pinch strength.

Flexor carpi ulnaris is a fusiform muscle located in the anterior compartment of the forearm. It belongs to the superficial flexors of the forearm, along with pronator teres, palmaris longus, flexor digitorum superficialis and flexor carpi radialis.

In fact, while at the muscle level, the flexors are con- siderably stronger than the extensors [3,14]; when including the wrist kinematics, extensor moment actually exceeds flexor moment.

Flexor Carpi Ulnaris Tendonitis is inflammation of the wrist flexor tendon at the pinky side of the wrist. It is common for patients to experience inflammation in their tendons, which can lead to tightness and pain when the tendon is subjected to excessive tension.

The flexor carpi radialis and flexor carpi ulnaris stretch from the humerus (upper-arm bone) along the inside of the forearm to the metacarpal bones of the hand and flex the wrist.

Pronator teres

Why are the muscles that move the fingers and wrist located in the forearm? This design allows the hand to maintain fine motor control and strength without the interference of bulky muscles. The forearm muscles can be divided into anterior flexors and posterior extensors, as well as __________.

If your extensor tendons are damaged, you’ll be unable to straighten one or more fingers. If your flexor tendons are damaged, you’ll be unable to bend one or more fingers. Tendon damage can also cause pain and swelling (inflammation) in your hand.

Because of that, you can strain a muscle or tendon with overuse over time or abruptly with a forceful movement. Forearm tendinitis is also common with overuse. Like all strains, forearm strains are graded from 1 to 3. Grade 1 is mild and involves no loss of strength.

The tendons that control movement in your hands, wrists and fingers run through your forearm. There are 6 tendons that help move your wrist. The wrist tendons are: Flexor carpi radialis: This tendon is one of two tendons that bend the wrist.

Wrist sprain pain may be felt as a sharp, throbbing pain or an intermittent, dull ache. The most common type of sprain (called a scapholunate ligament injury) causes pain in the center and/or thumb side of the wrist.

Symptoms of a wrist sprain are:

• Pain.
• Swelling.
• Tenderness and warmth around the injury.
• Feeling a popping or tearing in the wrist.
• Bruising.
• Loss of motion.
• Weakness.

An injury that is associated with the following signs or symptoms may be a tendon rupture:

• A snap or pop you hear or feel.
• Severe pain.
• Rapid or immediate bruising.
• Marked weakness.
• Inability to use the affected arm or leg.
• Inability to move the area involved.
• Inability to bear weight.
• Deformity of the area.

Your wrist hurts because you have stretched or torn ligaments, which connect the bones in your wrist. Wrist sprains usually take from 2 to 10 weeks to heal, but some take longer. Usually, the more pain you have, the more severe your wrist sprain is and the longer it will take to heal.

Tendons, muscles and bones work together to give our arms and hands full range of movement. A traumatic injury to a tendon can prevent us from fully extending our wrist or fingers. Tendon injuries such as cuts (lacerations) and severe tendon tears require immediate treatment to prevent permanent damage.

Recovery times vary based on severity and extent of the injury, but after a surgery to repair a torn ligament in the wrist, you will, conservatively, need at least six weeks for the tissues to fully heal themselves.
