Why Do You Need Trigger Finger Surgery?

An excruciating condition that causes the thumb or the finger to lock or catch when bent is called trigger finger. If the condition affects the thumb, it is aptly called trigger thumb.

Trigger finger or stenosing tenosynovitis occurs when the tendons in the thumb or the finger becomes inflamed.

The tendons are tough tissue bands that connect the bones and the muscles. Together, the muscles and the tendons in the arms and hands straighten and bend the thumbs and the fingers.

Typically, the tendon easily glides through the sheath (the tissue covering) because of the synovium. The synovium is the lubricating membrane that surrounds the joint.

However, there are instances when the tendon becomes swollen and inflamed. When this occurs, bending the thumb or the finger will pull the inflamed tendon through the narrowed tendon sheath.

This results to a pop or snap.

Treatment options can range from noninvasive alternatives (rest and medications) to trigger finger surgery.

The course of treatment that will be recommended will often depend on the severity of the condition.


Trigger finger is often attributed to forceful use or repeated movement of the thumb or finger.

Gout, diabetes, and rheumatoid arthritis have also been associated with the condition.

Some of the factors that increase one’s risk of developing trigger finger are the following:

  • Health problems – people suffering from rheumatoid arthritis or diabetes are at a greater risk of developing the condition.
  • Repeated gripping – Hobbies and occupations that require prolonged gripping and repetitive hand use.
  • Sex – trigger finger is more prevalent in women as opposed to men.

Why Do You Need Trigger Finger Surgery?


Common manifestations of trigger finger can include:

  • Tenderness
  • A nodule or a bump
  • Finger locking or catching
  • Inability to straighten the finger
  • Finger locked in a bent position
  • Stiffness of the finger (especially in the mornings)
  • Clicking or poppingsensation when the affected finger is moved


Diagnosis of the condition often does not involve elaborate testing. A physical examination and your medical history would often suffice.

During the examination, expect to be asked to close and open your hand. This is done so the doctor can check for evidence of locking, smoothness of motion, and areas of pain.

Your palm will also be checked for lumps.

Lumps that are associated with trigger will often move together with the finger because it is attached to the tendon.



Nonsteroidal anti-inflammatory drugs (naproxen and ibuprofen) are often given to provide pain relief. However, it won’t be able to relieve the swelling and inflammation.


If conservative noninvasive treatments are recommended, it can include the following:

  • Heat or ice. Some patients observe an improvement when the palm is iced several times daily. Others on the other hand experience improvement doing warm-water soaks first thing in the morning.
  • Rest. For patients whose work or hobbies involve repetitive gripping or prolonged grasping, a three to four-week rest would be recommended.
  • Stretching exercises. Doctors may prescribe gentle exercises in order to retain finger mobility.
  • Splint. A night splint for up to six weeks may be advised to keep the finger in an extended position.

Surgery and other procedures

For those with severe symptoms and those patients whose condition does not respond to conventional treatments, the following might be suggested:

Trigger finger surgery – The surgeon will cut open the constricted tendon sheath section through a small incision in the base of the affected finger. This procedure is often done in the operating room.

Percutaneous release – After the palm is numbed, the doctor will insert a needle into the tissue. Moving the needle and the finger will help break the constriction. This treatment is often done under ultrasound control so the tendon sheath will be opened without damaging the tendon or any of the nearby nerves.
