Why do the finger joints click, click and clap?


Many people can make their fingers click or snap, which is often referred to as joint twitching. The sound you hear is caused by bubbles of nitrogen, oxygen, and carbon dioxide moving in the fluid around your joints. Rest assured, the most common causes of snapping fingers are not usually a problem.

When the snapping or snapping of the fingers does not cause pain, it is usually harmless. However, if your noisy finger joints hurt or are swollen, you should see your doctor.

This article explains when snapping your fingers and cracking your joints can be a sign of a problem. Symptoms to look out for and possible treatments will also be discussed.

What Causes Cracks and Cracks in Joints?

Joints can crack and burst for many reasons. Some of the conditions that cause this include:

  • A condition known as trigger finger
  • Injuries to fingers and hands.
  • Arthritis

Index finger

The tendons in your hands are like strings attached to your fingertips. When the forearm muscles contract, the tendons clench the fingers into a fist. The tendons pass through a thin tube called the flexor tendon sheath. It goes from the middle of the palm to the tip of the finger.

If you have a condition known as trigger finger , this movement of the tendon is not smooth and can be painful and stiff. This can cause clicks. This can also cause you to develop swelling in the palm of your hand.

The reason for the trigger is often unclear. This can happen on multiple fingers, in different places, and at different times.

Trigger finger is about six times more common in women than in men. It is also more common in people with diabetes or rheumatoid arthritis .

Genetics and frequent hand use can increase the likelihood that trigger finger will develop.

Trigger finger can occur if the size of the tendon and the size of the sheath tendon opening are incompatible. This can happen when the tendon becomes inflamed or swollen.

This produces a clicking sensation when you relax your fist. If symptoms get worse, you may have to use your other hand to straighten your index finger, or it may not straighten at all.

Treatments for trigger fingers include steroid injections, rest, anti-inflammatory medications, and possibly surgery.

Ligament injury

Ligaments hold joints together and can be damaged by a toe sprain or dislocation . Ligaments can be partially or completely torn. If the ligament does not heal properly and is too loose, the joint can burst and break when bending the fingers.

Common symptoms of a ligament injury include joint pain and swelling. If the ligament does not heal properly, the joint can burst or break during flexion.

Finger ligament injuries can be considered minor problems. However, if not treated properly, they can lead to long-term finger joint problems. If you suspect that you may have a ligament injury, it is best to see your doctor.


Osteoarthritis of the fingers is the abrasion of the normally smooth cartilaginous surfaces of the joints. As arthritis worsens , joint movement can become painful. Arthritic finger joints often cause joint inflammation.

Arthritis in the fingers can cause cracking and popping. It can occur as a result of small, sharp bone overgrowth around joints affected by arthritis . These growths, known as bone spurs, can create uneven surfaces and joint problems. You may notice a small bump around an arthritic joint called a mucous cyst .

Osteoarthritis of the hand is more common in women over the age of 50. It is believed that it also originates in the family.

Manual labor or a history of repetitive hand use can also increase the chance of developing arthritis in the hand.

Treatment of cracks and fissures in the joints.

Treatment may include:

  • Injections
  • Operation
  • Wear a splint
  • Physiotherapy

People often start with a simple approach to treatment. If symptoms worsen or reappear, a more invasive treatment may be recommended.

When to contact a healthcare provider

  • If the joint looks swollen, inflamed, or discolored
  • If you cannot fully extend your finger
  • If there is numbness in the fingertip.
  • If there is pain on the palmar side of the finger, especially in the fold of the joint.
  • If the morning stiffness lasts about 30 minutes.
  • If the toe joint looks enlarged or deformed
  • If a dull burning sensation appears in the fingers
  • If there is pain in the joint.
  • If there is a loss of flexibility or a grinding sensation


Cracking, cracking, or popping fingers and joints are generally not a cause for concern. However, you should speak to your doctor if you have pain in your fingers, numbness, or a burning sensation. You should also see your doctor if you notice swelling or have trouble moving your fingers.

These symptoms can be signs of a trigger finger, ligament injury, or osteoarthritis. If so, know that there are treatment options. These may include injections, surgery, splints, and physical therapy.

Frequently asked questions

  • Trigger finger (stenosing tenosynovitis) is the most common cause of popping in the finger joints.

  • Trigger finger usually affects people over the age of 40. People who use their hands or fingers a lot, such as farmers, musicians, and industrial workers, often suffer, as do people with osteoarthritis , rheumatoid arthritis , gout , or diabetes.

  • In addition to popping or popping, the index finger can cause grip pain or discomfort, joint stiffness, finger lock, and a painful lump or swelling in the palm of the hand.

  • In most cases, trigger finger is treated with rest, over-the-counter anti- inflammatory medications , finger exercises, and a finger brace. Severe cases can be treated with steroid injections or a surgery called tenolysis to release scar tissue from the tendons.

  • Osteoarthritis, also known as "wasting arthritis," is characterized by loss of articular cartilage and changes in the underlying bone. Movement of the affected finger joint can cause a squeak, snap, or popping sound called crepitus .
