<\/p>\n\n

When that tingling that comes and goes in the ring finger and pinky appears, it is normal to think that “the hand fell asleep” and that’s it. Even so, if the pattern repeats itself, it is worth considering cubital tunnel syndrome: when to suspect it if you have tingling in the ring and little fingers<\/strong>, because many times the origin is in the elbow, due to compression of the ulnar nerve. <\/p>\n\n

<\/p>\n\n

The important detail is the context: if the symptoms worsen when you bend your elbow<\/a> for a while (when talking on the phone, driving, using the computer or sleeping), the picture fits quite well with this compression neuropathy.<\/p>\n\n

<\/p>\n\n

What is cubital tunnel syndrome?<\/h2>\n\n

What is cubital tunnel syndrome?<\/figcaption><\/figure>\n\n

<\/p>\n\n

Cubital tunnel syndrome is a compression of the ulnar nerve at the elbow. It is considered one of the most common neuropathies due to entrapment of the upper limb, after carpal tunnel syndrome. <\/p>\n\n

<\/p>\n\n

The classic site of compression is in the epitrochleo-olecranian canal, on the inner side of the elbow joint, where the nerve passes through a narrow and vulnerable space.<\/p>\n\n

<\/p>\n\n

Anatomy of the ulnar nerve and its passage through the elbow<\/h3>\n\n

<\/p>\n\n

The ulnar nerve runs down from the neck, runs along the inside of the arm, and passes behind the epitrochlea<\/strong>, the bony relief that many people call the “funny bone.” When someone hits themselves there, it feels like a current running towards the forearm and hand, because the nerve is poorly protected in that area. <\/p>\n\n

<\/p>\n\n

The nerve then continues to the hand and can also be compressed in the wrist, as it passes through the tunnel of Guyon, before distributing sensation and control to various muscles in the hand. Distribute sensation and control of various muscles in the hand<\/a>.<\/p>\n\n

<\/p>\n\n

Why is tingling felt in the ring finger and pinky?<\/h2>\n\n

<\/p>\n\n

The ulnar nerve carries sensation of the entire pinky and the inner half of the annular nerve. It is also involved in the control of small muscles that help pincer, open the hand, and coordinate fine movements. <\/p>\n\n

<\/p>\n\n

Relationship between compression and symptoms in the fingers<\/h3>\n\n

<\/p>\n\n

If the nerve is compressed near the medial epicondyle<\/strong> (inner elbow area), electrical conduction is disturbed. That is why tingling, numbness or a sensation of current appears right in those two fingers. <\/p>\n\n

<\/p>\n\n

The longer the compression is maintained or the more it is repeated, the easier it is for the tingling to go from occasional to frequent, and even constant.<\/p>\n\n

<\/p>\n\n

Typical symptoms and warning signs<\/h2>\n\n

<\/p>\n\n

Symptoms don’t always start with severe pain. Sometimes the onset is discreet and is more noticeable at night or in sustained positions. <\/p>\n\n

<\/p>\n\n

Numbness and tingling in the ring finger and pinky<\/h3>\n\n

<\/p>\n\n

It is usually the first symptom. Many people notice that it worsens with a bent elbow: when sleeping with the arm bent, when holding the cell phone, when resting the elbow on the armrest, or when maintaining a fixed posture. <\/p>\n\n

<\/p>\n\n

If the problem progresses, the numbness stops coming and going.<\/p>\n\n

<\/p>\n\n

Elbow pain and tenderness in the inner forearm area<\/h3>\n\n

<\/p>\n\n

A dull elbow pain<\/strong> may appear, with discomfort towards the sensation of the inner area of the forearm<\/strong>. It is sometimes confused with an irritation of tendons on the inside of the elbow, which is why the clinical examination makes a difference. <\/p>\n\n

<\/p>\n\n

Weakness in the hand and clumsiness when grasping<\/h3>\n\n

<\/p>\n\n

When the compression is more marked, weakness appears: it is difficult to open jars, force the grip, manipulate small objects or separate the fingers.<\/p>\n\n

<\/p>\n\n

In advanced stages, atrophy of the muscles of the hand may be noticed, which indicates that the nerve has been suffering for some time and it is advisable to act without delay.<\/p>\n\n

<\/p>\n\n

Common causes and risk factors<\/h2>\n\n

<\/p>\n\n

There are daily habits that favor irritation of the ulnar nerve. The relevant thing is that many are modifiable. <\/p>\n\n

<\/p>\n\n

Direct pressure on the elbow (epitrochlea and medial epicondyle)<\/h3>\n\n

<\/p>\n\n

Resting the elbow for long periods on hard surfaces (desk, table, armrest) can irritate the nerve due to repeated pressure.<\/p>\n\n

<\/p>\n\n

There is also nerve subluxation<\/strong>, when the nerve shifts when bending the elbow and rubs again and again, generating inflammation. generating inflammation<\/a>.<\/p>\n\n

<\/p>\n\n

Prolonged bending of the elbow in sleep or from repetitive activities<\/h3>\n\n

<\/p>\n\n

Sleeping with your elbows bent too much or working with your arm bent for hours increases the pressure inside the tunnel. Over the years, the cubital tunnel ligament<\/strong> can thicken and reduce the space available for the nerve, making it easier for symptoms to appear. <\/p>\n\n

<\/p>\n\n

How is cubital tunnel syndrome diagnosed?<\/h2>\n\n
\"How
How is cubital tunnel syndrome diagnosed?<\/figcaption><\/figure>\n\n

<\/p>\n\n

The diagnosis is based on the medical history, the physical examination and, if necessary, studies that measure the functioning of the nerve.<\/p>\n\n

<\/p>\n\n

History and physical examination<\/h3>\n\n

<\/p>\n\n

The professional usually asks when the tingling has been occurring, what triggers it, if there is a nighttime worsening, and if it is accompanied by elbow pain or loss of strength.<\/p>\n\n

<\/p>\n\n

The examination checks sensation, strength, coordination, reflexes and pain points in the elbow and forearm.<\/p>\n\n

<\/p>\n\n

Nerve conduction studies and electromyography<\/h3>\n\n

<\/p>\n\n

Nerve conduction studies<\/strong> measure the speed at which the impulse travels down the nerve. If there is compression, that speed may decrease. <\/p>\n\n

<\/p>\n\n

Electromyography<\/strong> assesses the electrical activity of the muscles that depend on the ulnar nerve and helps estimate the degree of involvement. In specific situations, X-rays<\/strong> are also requested to rule out bone causes that narrow the passage of the nerve. rule out bone causes that narrow the passage of the nerve<\/a>. <\/p>\n\n
