Is your thumb sprained? (Thumb Sprain) Don't panic, let's find out about this!

While going about our daily activities, it is normal to sometimes have minor accidents. Maybe you have also sprained your limb. Especially when it comes to a sprained thumb, the pain and swelling can be very annoying, right? So, today we will talk about this condition called Thumb Sprain in detail.

What is a thumb sprain?

Simply put, a thumb sprain is an overstretching or tearing of a ligament in your thumb, the tissue that connects two bones at a joint. Most often, this condition occurs when the Ulnar Collateral Ligament (UCL) is damaged, located on the inside of your thumb, near the metacarpophalangeal (MCP) joint. Imagine, for example, if your thumb suddenly bends back, away from your hand, or twists in some other unusual way, you could have a sprain.

These sprains, like other sprains, can range from a minor pull to a complete tear of the ligament, possibly even separating it from the bone. This condition is sometimes called "Skier's Thumb" or "Gamekeeper's Thumb."

What are the types of thumb sprains?

Doctors classify these sprains according to their severity. There are three main types:

• Grade 1: This is the mildest sprain . The ligament is stretched too much, but not torn.
• Grade 2: This is a moderate sprain . Here, part of the ligament is torn.
• Grade 3: This is the most severe sprain . The ligament may be completely torn or may even be detached from its attachment to the bone. Severe sprains like this may require immediate medical attention, possibly even surgery.

Is my thumb broken? Is it sprained? How do I know for sure?

Both a fractured and a sprained thumb can cause pain, swelling, and bruising. However, there are some differences. A broken thumb is usually more painful , and the thumb may be deformed or look disfigured. You may also feel something like numbness.

If you have pain, swelling, or bruising in your thumb after an accident like a fall, you should definitely see a doctor . It's hard to tell from the outside whether it's a fracture or a sprain. Therefore, it's best to have an experienced doctor examine you and, if necessary, take an X-ray to find out exactly what's wrong.

What is the difference between a sprain and a strain?

Although both are painful, there is a slight difference.

• A sprain , as we discussed earlier, is an injury to the ligaments that connect the bones of a joint.
• A strain is an injury to a muscle or to the tendon that connects a muscle to a bone.

If you have pain in your thumb, see a doctor. He or she will examine you and, if necessary, order tests such as an X-ray , musculoskeletal ultrasound , or MRI (Magnetic Resonance Imaging) to determine if there is a fracture, sprain, or muscle strain.

Who is at higher risk of spraining their thumb?

Anyone, at any age, can sprain their thumb. However, some people are at higher risk.

• Athletes: This risk is especially high for those who ski , as well as those who play sports that involve catching and throwing a ball (e.g. baseball, basketball, volleyball, soccer).
• People at higher risk of falling: Older people who are prone to falling frequently, or those who have balance problems, are also at higher risk.

In fact, a sprained thumb is a relatively common injury .

What are the symptoms of a sprained thumb?

Symptoms depend on the severity of the sprain. Symptoms vary according to the three levels we discussed earlier.

Grade 1 (mild sprain)

• Pain at the base of the thumb or pain when pressed .
• Swelling in the thumb or at its base.
• Seeing a bruise (blueness) at the base of the thumb.

Sometimes, people with mild sprains may not feel much pain immediately after the injury.

Grade 2 (Moderate Sprain)

• Limited function and range of motion of the thumb.
• Severe pain at the base of the thumb and pain when pressed .
• Swelling in the thumb or at its base.
• Seeing a bruise at the base of the thumb.

Grade 3 (severe sprain)

• Severe pain at the base of the thumb and pain when pressed .
• A feeling of looseness or instability in the thumb joint.
• Difficulty gripping something between the thumb and index finger.
• A lump-like sensation in the thumb. This can occur when the ulnar collateral ligament (UCL) is completely torn. The end of the torn ligament may feel like a lump under the skin.
• Swelling in the thumb or at its base.
• Seeing a bruise at the base of the thumb.

What are the causes of thumb sprains?

The main cause of a thumb sprain is a sudden, forceful force that causes the thumb to bend away from the hand, back, or twist in another unusual direction . This often happens when an outstretched hand hits the ground.

It is also common when a skier falls while holding a ski pole . That is why it is also called "Skier's Thumb".

Sometimes, people who engage in repetitive, repetitive activities (e.g., certain sports, certain occupations) that involve gripping or twisting things for long periods of time can develop ligament damage and sprains. This long-term condition is also known as "Gamekeeper's Thumb."

How do doctors diagnose a thumb sprain?

When you see a doctor, they will first ask you about how the injury happened, when it happened, and what your symptoms are . Then, they will do a physical exam to see how stable your thumb joint is and where the pain is coming from. This will help determine if it is a sprain and how severe it is. They may also order imaging tests, as mentioned earlier.

Diagnostic tests

After a physical examination, the doctor may order tests such as these to check for other injuries or to determine the exact severity of the sprain:

• X-rays:
• This can take detailed pictures of the bones. This can help determine if your pain and swelling are due to a fracture.
• Also, you can check to see if the ligament is pulling and causing an avulsion fracture , which is a condition where the ligament comes off the bone with a small piece of bone.
• Stress X-ray: This involves the doctor applying slight pressure to your injured thumb while taking the X-ray. This can provide more information about the stability of the MCP joint . If the pressure causes pain, the doctor may also inject a numbing medicine (anesthetic) into the area near the thumb.

• MRI (Magnetic Resonance Imaging):
• MRI can take detailed pictures of the inside of the body without using radiation. It can see details of bones that cannot be seen on regular X-rays, as well as details of soft tissues (such as the extent of a sprain or muscle strain). This information helps the doctor plan treatment and decide whether surgery is necessary.

• Musculoskeletal Ultrasound:
• This uses sound waves to take pictures of the body. Your doctor may order an ultrasound to look at the soft tissues around a joint. This can help determine if ligaments are partially torn, completely torn, or if fluid is accumulating. This can help determine the severity of the injury and the best treatment.

How do you treat a sprained thumb?

The treatment method depends on the severity of the sprain.

Treatment for mild sprains (Grade 1)

These can usually be treated at home by following the PRICE method (Protection, Rest, Ice, Compression, Elevation).

• Protection: Wear a thumb spica splint for a few days to immobilize the injured area. These can be purchased at pharmacies or online.
• Resting your hand: Avoid using your injured hand for at least 48 hours after the injury. This is easier to do if you have a splint. If you don't have a splint, avoid using your hand/thumb in any way that causes pain.
• Icing your thumb: Apply ice to your thumb and hand as soon as possible after the injury. This can help reduce swelling. Ice massage can help to target the pain. Wrap an ice cube in a cloth and rub it in a circular motion on the painful area for three to five minutes several times a day. Sometimes an ice bath can also help - immerse your thumb and hand in ice water for three to five minutes. However, be careful not to overdo it and you could get frostbite.
• Using a compression bandage: Wrap the injured thumb joint with an elastic compression bandage . Some thumb spica splints also have this elastic feature. This can also reduce swelling.
• Elevating your hand: When at rest, keep your hand above your heart as much as possible.
• Taking pain relievers: Over-the-counter pain relievers, such as aspirin and ibuprofen, can help with pain and swelling.

If the pain and swelling do not subside after two days of rest and these home treatments, definitely see a doctor .

Treatment for moderate sprains (Grade 2)

• Wearing a Thumb Spica Splint or Cast: Your doctor will likely recommend that you wear a splint or cast to immobilize your thumb until it heals. Depending on the severity of the sprain, you may need to keep it in place until your doctor tells you to remove it.
• Ice your thumb and hand: Apply ice as soon as possible after the injury. This can help reduce swelling.
• Taking painkillers: Use painkillers that you can buy at the pharmacy.
• Stretching exercises: The thumb can become stiff because it is immobile. Therefore, your doctor may recommend some stretching exercises to help regain movement in your thumb. Follow your doctor's instructions on when to start these exercises.

Treatment for severe sprains (Grade 3)

• Undergoing surgery: When a ligament is completely torn, surgery is often necessary. There are various surgical procedures, such as reattaching the ligament to the bone, fixing an avulsion fracture with a bone anchor, pin, or screw.
• Wearing a cast or splint: After surgery, you will need to wear a cast or splint for about 6 to 12 weeks to help your thumb heal.
• Occupational/Physical Therapy: Once your thumb heals after surgery, your medical team will tell you to do special exercises to help you regain strength and range of motion in your thumb and hand.

Do you need to go to the hospital if you sprain your thumb?

We all get aches and pains from time to time, but persistent pain is not normal. If you have injured your thumb, and you still feel pain after resting for a couple of days and applying ice, you should definitely see a doctor . He or she will likely run tests to see if there is a more serious injury, or may prescribe a splint to stabilize your thumb.

How long does it take for a sprained thumb to heal?

The time it takes for this to happen depends on the severity of the sprain. A mild sprain (Grade 1) usually heals in about four to six weeks, but only if you immobilize the thumb with a splint or cast and avoid activities that can irritate it.

It may take several months for a severe sprain (Grade 3) to fully heal and for you to be able to use your thumb normally. This is because severe sprains usually require surgery, followed by splinting/casting, and physical therapy.

How do I take care of a sprained thumb?

Follow your doctor's instructions exactly. Since the ligament takes time to heal, try to avoid activities and sports that use your hands for at least a month.

How to prevent thumb sprains?

There are several things you can do to prevent a thumb sprain:

• Before doing any exercise or sport that uses your hands , stretch the muscles in your hands and fingers well .
• Wear protective equipment when playing sports.
• Exercise on flat surfaces to avoid falls.
• Wear shoes that fit well and make sure your shoelaces are tied properly. This will reduce the chance of them getting tangled.
• When skiing, if you're about to fall, let go of your ski poles , don't hold on too tightly.
• If you are at high risk of falling, use a walking aid such as a cane or walker.

What is the prognosis for a sprained thumb?

Mild (Grade 1) and moderate (Grade 2) thumb sprains usually heal well without long-term complications if treated with proper rest and immobilization of the thumb.

Many studies show that surgery for severe (Grade 3) ulnar collateral ligament (UCL) sprains is generally successful. Grade 3 UCL sprains that are not treated surgically usually result in chronic instability .

Can a sprained thumb cause complications?

The potential for complications depends on the severity of the sprain and the ligaments damaged. Some of the complications that can occur from a thumb sprain include:

• Chronic pain in the thumb.
• Arthritis of the thumb joint.
• Instability of the thumb joint.
• Decreased pinch strength .
• Nerve damage from surgery.
• Decreased range of motion in the thumb joint.

When should I see a doctor?

If you have symptoms of a thumb sprain, such as thumb pain and joint instability, see a doctor .

If you already have a sprained thumb, tell your doctor if you develop any new, bothersome symptoms.
