Is your hand just bent inward like a claw? Let's talk about 'Claw Hand'!

Have you ever had your fingers curl inward, like a claw? Or have you ever felt pain or difficulty straightening your fingers? Maybe you have some idea about this condition called 'claw hand' . Don't worry, we'll talk about it in more detail today. Because for some people, this can be something they are born with, while for others, it can develop later in life due to an accident or other illness.

What is this Claw Hand?

Simply put, claw hand is a condition in which your fingers, especially the ring and little fingers, are bent inward and your wrist is pulled inward. It is called claw hand because it looks like your hand is trapped in a claw shape. Doctors sometimes refer to this as Ulnar Nerve Palsy . In this condition, you may find it difficult, if not impossible, to straighten all of your fingers.

Think about it, there are many small muscles in our hands that help us bend and extend our fingers. These muscles work with electrical signals, or nerve messages, that come from our brain and spinal cord. The Ulnar Nerve is one of the main nerves that comes from the inside of our hand, especially the muscles associated with the ring finger and little finger, and helps us bend and extend our fingers. Most of the time, this claw hand occurs when something is damaged in the Ulnar Nerve.

This can be something you are born with (as a congenital hand difference ), or it can be caused by an accident, illness, or nerve damage later in life.

What is the difference between Claw Hand, Dupuytren's Contracture, and Trigger Finger?

Now you might be thinking, "There are other conditions that cause the fingers to bend and become difficult to straighten, so how is this different?" Yes, you're right. Just like Claw Hand, Dupuytren's Contracture and Trigger Finger also cause difficulty in straightening the fingers. But the causes are different. Let's see what they are.

• Claw Hand: As we mentioned earlier, this is often caused by damage to your ulnar nerve . This nerve controls the muscles in your thumb and index finger. So when the ulnar nerve is damaged, the electrical signals that it controls to straighten your fingers don't get through properly. That muscle then weakens, overpowering the muscles that work on the other side, causing your fingers to curl inward.

• Dupuytren's Contracture: This is a condition that is often caused by genetic factors. It is a condition in which the tissue under the skin of the hand and fingers (especially the fascia , a rubber band-like structure that supports the hand and fingers and helps them move) thickens and tightens. Small nodules form under the skin of the hand, sometimes forming cords. Over time, these nodules and cords can cause the fingers to be pulled inward and bent so that they cannot be straightened. This is usually painless, but it can make it difficult to use the hand.

• Trigger Finger and Trigger Thumb: These conditions are caused by inflammation of the tendons (the strong tissue that connects muscles to bones) in your hand. When your tendons are constantly stressed or you do the same thing over and over again, they can become injured and swollen. This inflammation causes the tendon to become trapped in the sheath that it travels through. This can cause a popping or popping sound when you try to bend or straighten your finger. Sometimes, the finger can get stuck in a bent or extended position. This can be painful.

Do you understand the difference? The main difference is the reason.

Who is most likely to develop Claw Hand?

Claw Hand can develop in anyone. However, studies have shown that men are slightly more likely to develop it than women. Other than that, there is no significant age difference.

How does Claw Hand affect my body?

You can imagine how uncomfortable it is to not be able to use your fingers properly. Especially if you were not born with this condition and it develops later, it will take some time to get used to it.

• Difficulty holding and touching things: This can affect things like holding a small object, writing something, or holding a cup.
• Difficulty performing daily tasks: If your job requires you to use both hands, for example, typing on a computer or holding something, this condition can interfere with those tasks. If you are a school-going child, this can also affect tasks such as writing.

What are the symptoms of claw hand?

The main and most obvious symptom is a claw-like hand , meaning the fingers are bent inward and the wrist is pulled inward.

• Difficulty straightening fingers: It is very difficult to extend the fingers away from the wrist, and sometimes you may not even be able to move your fingers.
• It's hard to "open" your hand: Normally, we open our hand from the middle of the palm with our fingers spread wide, which can be difficult to do.
• Numbness or tingling: If the cause of this claw hand condition is damage to the ulnar nerve, you may experience numbness or tingling from your forearm down to your wrist, ring finger, and little finger. Sometimes, there may be a loss of sensation in that area.

What are the causes of claw hand?

There are several possible causes of claw hands. Let's take a look at them.

• Damage to the Ulnar Nerve or its branches: An injury (such as a cut, bruise, or pull) to your neck, chest, armpit, or anywhere else in your arm can damage the Ulnar Nerve, which runs from the sides of your neck down your arm to your wrist.
• Cubital Tunnel Syndrome: Also known as Ulnar Nerve Entrapment, this condition occurs when the ulnar nerve, which runs through a tunnel on the inside of your elbow, becomes compressed. It's like a water pipe being blocked. This pressure prevents the ulnar nerve from working properly. This can cause muscle control in your hand to be impaired, and you may experience numbness or tingling in your forearm, wrist, ring finger, and little finger. People who put constant pressure on their elbows and wrists, or who do jobs that require them to bend and stretch their elbows and wrists (e.g., people who work at a computer with their elbows bent for long periods of time, or those who play certain sports) are more likely to develop this condition.
• Congenital Hand Difference: "Congenital" means "present from birth." Some babies are born with a hand difference. Claw Hand can be one such congenital condition.
• Cervical Spondylosis: Simply put, this is a condition that occurs with age due to the wear and tear of the vertebrae (bones at the neck of the spine) and the cartilage between them. This can cause symptoms such as neck pain and stiffness. In some people, this condition can also cause reduced hand function and conditions such as claw hand. This is because the nerves that go to the hands start in the neck.
• Scar Tissue: Scar tissue that forms after the skin on your hand or forearm has healed, such as a severe burn, can sometimes be very hard. This hard scar tissue can cause your fingers to pull inward, leading to a claw hand.
• Infections: This is a bit rare, but some infections that affect the nervous system, such as leprosy, can also cause claw hand.

How is Claw Hand diagnosed?

If you have these symptoms, the first thing you should do is see a doctor. The doctor will examine you.

• Physical examination: The doctor will look at your hand and check things like whether you can bend and straighten your fingers, how far you can, how well they feel, and whether you can use your hand as you normally would.
• Electromyography (EMG): If your doctor suspects that you have claw hand or another nerve problem, he or she may order an EMG (Electromyography) test. This involves inserting very fine needles through your skin into your muscles, and using electrodes on the needles to measure the electrical activity of your muscles as you move them. This can help determine if your ulnar nerve has been damaged, where it is, and how severe it is.

If a baby is born with this condition, a doctor will diagnose it as soon as the baby is born.

How to treat claw hand?

The good news is that there are several ways to treat claw hand. The type of treatment you need will depend on the cause and how severe your symptoms are.

The following can be done as treatment:

• Stretching exercises: Your doctor or physical therapist will teach you specific stretching exercises for your forearm, wrist, and hand. These can be done at home.
• Wearing a splint or brace: A splint (a support made to fit the shape of the hand) or brace may be worn to support the affected finger. This can help prevent the finger from becoming abnormally bent and stiff, and can help it gradually straighten.
• Physical Therapy: You can seek treatment from a physical therapist to improve the strength and flexibility of your hand. They will teach you the right exercises and treatments.
• Surgery: In some cases, especially if the nerve is pinched or if other treatments do not help, surgery may be necessary.
• Medication: If the cause of claw hand is an infection, medication may be given to treat the infection.

Surgery for Claw Hand

Sometimes, surgery may be needed to free your fingers and reduce the symptoms of claw hand. There are several types of surgery:

• Nerve Repair: Repairing an injured nerve.
• Tendon Release: Loosening and releasing tight tendons.
• Skin Grafts: If scar tissue has formed due to burns, the hardened skin is removed and skin is grafted from another area.
• Tendon Transfer: A healthy tendon is transplanted to a dysfunctional muscle and attached to it. This can restore some function to the hand.

Your doctor or surgeon will explain to you what kind of surgery you need and what to expect afterward.

How long does it take to recover after treatment?

This will vary depending on the type of treatment you receive. If you have to wear a splint, you will need to wear it for several months. Stretching exercises and physical therapy are long-term treatments. It can sometimes take a year or more to fully heal.

If you have surgery to repair your claw hand, your surgeon will tell you about the recovery period. Most people will need several months to recover after surgery. You will then need physical therapy to regain strength in your hand. However, if the cause is severe damage to the ulnar nerve, you may have long-term nerve symptoms (such as numbness or loss of sensation).

Can this situation be prevented?

Many of the causes of claw hands, especially if you are born with them, are difficult to prevent.

However, you can do these things to prevent damage to the ulnar nerve and conditions like cubital tunnel syndrome:

• Avoid leaning on your elbows: Many people lean on their elbows while working at a desk or watching TV. This can put pressure on the ulnar nerve.
• Avoid applying pressure to the inside of your hand.
• If you often use a computer chair, don't rest your elbows on the armrests. Keep the chair elevated.
• Try to sleep with your elbows straight. Some people sleep with their elbows bent, which is also not good.
• Avoid overusing your hands and elbows. Take short breaks when working in the same position for a long time.
• Give your body a break after strenuous physical activity.

What should I expect if I have a claw hand?

Claw hand is a condition that sometimes resolves itself temporarily, but it can also be a long-term problem. How long it affects you depends on the cause and how your fingers and hand respond to treatment.

Some people recover completely with a brace and physical therapy. Others may still have some loss of function in their hand after surgery. Ask your doctor or surgeon about how much recovery you can expect based on your condition.

Will I be unable to go to work or school because of claw hand?

If you have a job that uses your hands, or if you use all your fingers for schoolwork, you may not be able to go to work or school until you recover. Ask your doctor what types of activities you can do with your affected fingers and what accommodations you can get.

How do I take care of myself?

• If you have been prescribed a splint or brace, be sure to wear it as directed and for as long as the doctor tells you.
• Also, if you are working with a physical therapist, do the exercises he or she teaches you as often as possible, and do them correctly.
• If your symptoms get worse, or if you experience unbearable pain, tell your doctor immediately.

When should I see a doctor?

If you notice any changes in your hand or fingers (such as pain, stiffness, numbness) that don't improve within a few days, see a doctor as soon as possible. The sooner you start treatment, the better your chances of recovery.

When should I go to the Emergency Department (ETU) ?

If you have a traumatic event , such as a fall or car accident, or if you have any of these symptoms, go to an emergency room immediately:

• If you can't move or use your hand normally.
• If you lose feeling in your hand or forehead.
• You think you have a broken bone.

What questions should I ask my doctor?

When you see a doctor, don't forget to ask questions like these:

• Do I have claw hand, or is it another condition?
• What kind of treatment do I need?
• Will I need surgery?
• How long will I need to wear a brace or go to physical therapy?
• How long will it take to fully recover?
• Could this situation happen again?

Anything that makes you unable to use your hand normally can be scary and distressing. Claw Hand can have many causes. So see a doctor as soon as you notice any changes in your fingers, hand, or forearm.
