Texting and Typing: Common Hand and Wrist Injuries

Technology dominates today’s world. From our phones to our TVs to our computers, we spend significant time in front of a screen each day, often texting or typing at the same time. In fact, according to Rush University, the average American spends around 23 hours per week texting! With the rise of these devices, concerns have emerged over their prolonged effects on hand and wrist health.

How Texting and Typing Affect the Hand and Wrist

Texting, typing, swiping, and scrolling all create repetitive stress on the hand and wrist – similar to sports like golf or baseball. Despite their gentler nature, the consistency of these technological motions adds up, leading to inflammation in joints and along tendons. Over time, this wear and tear can cause pain, swelling, and reduced mobility.

This all said, it should be noted that the relationship between chronic cell phone use and hand and wrist injuries is not fully understood. Most evidence is anecdotal (even if compelling) – patients complaining of new pain or worsening pain with increased technology use – and larger scale studies are needed to establish a causal relationship between the two.

Common Injuries

De Quervain’s Tenosynovitis 

Also known as “mommy’s thumb” or “texting thumb,” De Quervain’s tendinosis refers to a swelling of the tendons around the base of the thumb. Anatomically, these tendons are covered by a slippery layer of tissue that can become irritated with repetitive strain (such as lifting a baby), causing friction and pain with thumb and wrist movements.

An easy way to diagnose De Quervain’s syndrome is using the Finkelstein test. Starting with a thumb’s up sign, tuck your thumb into your wrapped fingers and hold it tight. Then, bend your wrist down, stretching out the thumb side of your wrist – if you feel pain on the outside of the wrist, then you may have De Quervain’s tenosynovitis.

Treatment can be either non-surgical – consisting of immobilization of the wrist in a splint, over the counter pain medication, and physical therapy/stretching – or surgical. Surgery consists of cutting open the tendon sheaths, reducing friction and giving tendons space to heal.

Trigger Finger

Trigger finger is when a digit becomes consistently locked or catches while bending or straightening. It is often accompanied by a click or pop with every movement. The ring finger and thumb are most commonly effected, though the exact causes are not well known apart from forceful or repetitive hand injury.

The tendons of the fingers are held closely to the bones by a series of tissues called “pulleys.” When the finger is bent, the tendon must pass through these pulleys. When a pulley becomes inflamed, the tendon may have difficulty gliding through, in turn causing inflammation of the tendon and creating a small lump. It is this small lump that can catch on the pulley, causing the jerking motion, popping, and pain associated with trigger finger.

Diagnosis is usually straightforward, as the jerking motion associated with trigger finger is quite conspicuous. The doctor may also check for the small lump on the tendon as well as inflammation around the finger. The most conservative treatments consist of wrist, splinting, stretches, and medication. If those are unsuccessful, steroid injections can be used to reduce inflammation and resolve the lump. Finally, surgery to cut the affected pulley and allow for smooth movement is also an option.

Cubital and Carpal Tunnel Syndrome

Pressure or stretching of the ulnar nerve of the arm (also known as the funny bone nerve), is known as cubital tunnel syndrome, or “cell phone elbow.” Symptoms include numbness or tingling (“pins and needles”) in the ring and pinky fingers as well as pain and weakness. All of these stem from compression of the nerve, which can occur when bending the elbow at an acute angle (e.g., holding the phone to your ear for extended periods).

Diagnosis is sometimes assisted by electrical conduction tests, which exam a nerve’s ability to transmit an electrical signal. In the case of cubital tunnel syndrome, this transmission is impaired. Once diagnosed, treatment options range from rest, to splinting, to surgery, in which structures that are placing pressure on the nerve may be removed, or the nerve may be moved to a safer location.

Carpal tunnel syndrome – a similarly named and common condition – is similar to cubital tunnel syndrome, but refers to pressure on the median nerve, which connects to the thumb, index, and middle fingers of the hand. It has also been associated with excessive texting and typing.

Other Possible Injuries

The list above is certainly not exhaustive; it is meant to point out some of the more unique injuries linked to typing and texting. However, many of the most common hand and wrist injuries – e.g., arthritis and tendonitis – have also been associated with texting and typing, as have conditions of the neck and shoulder.
