Trigger Finger: Causes, Symptoms and Treatment in Pune

A finger that clicks, catches, or gets briefly stuck in a bent position before it suddenly releases is one of the more unusual-feeling hand problems patients describe. It is common enough that most hand and orthopaedic clinics in Pune, including this one, see it regularly, particularly in people who grip tools, kitchen equipment or a two-wheeler handle through the day.

What Trigger Finger Is

The medical name is stenosing tenosynovitis. Tendons that bend the fingers pass through a series of tunnel-like pulleys that keep them close to the bone. When the tendon or the sheath around it thickens or becomes irritated, the tendon has trouble gliding smoothly, especially where it enters the first pulley at the base of the finger. The finger catches at that point, and with more irritation, it can lock in a bent position until it is pulled straight, sometimes with an audible or felt pop.

Who Gets It

• People whose work or daily routine involves repetitive gripping, such as kitchen work, using hand tools, or operating a two-wheeler clutch and brake through Pune traffic
• People with diabetes, who have a meaningfully higher chance of developing it, sometimes in more than one finger
• Adults in their forties to sixties, and more often women than men
• People with other conditions that affect the tendons or connective tissue

Symptoms to Watch For

• Stiffness in a finger that is worse first thing in the morning
• A popping or clicking sensation when bending or straightening the finger
• A tender, firm lump felt at the base of the finger on the palm side
• The finger catching partway through movement, or locking in a bent position
• In more advanced cases, the finger staying bent until it is straightened with the other hand

How It Is Diagnosed

Trigger finger is usually diagnosed from the history and a hands-on examination. The doctor feels for the tender nodule at the base of the finger and watches the finger bend and straighten to see where it catches. Imaging is not usually needed. If diabetes or thyroid disease has not been checked recently, it is reasonable to review this alongside the hand problem, since both can influence treatment and recovery.

Treatment: From Simple Measures to a Short Procedure

Treatment is generally staged, moving from the simplest, lowest-risk options first toward a procedure only if needed.

A steroid injection is often tried before considering a procedure, and it works well for many people, sometimes for a period of months and sometimes long-term. If the finger keeps locking after one or two injections, a short day-procedure to release the tight part of the tendon sheath is usually the next step. It is done under local anaesthesia, takes a short time, and most people are back to light daily tasks within a few days.

Trigger Finger vs Other Causes of a Stiff Finger

Not every stiff or catching finger is trigger finger. Osteoarthritis at the base joints of the fingers causes stiffness and sometimes swelling, but it does not usually produce the catching or locking sensation that is typical of trigger finger. Dupuytren's contracture, a thickening of tissue in the palm, pulls a finger into a bent position gradually over time rather than causing it to catch and release suddenly. Telling these apart matters because the treatment is different, which is why a hands-on examination, rather than a description over the phone, is the reliable way to reach the right diagnosis.

What Happens During a Trigger Finger Release

1. A small amount of local anaesthetic numbs the base of the finger
2. A small incision is made over the tight part of the tendon sheath, or in some cases the release is done through a needle technique without an open incision
3. The tight part of the pulley is divided so the tendon can glide freely
4. The finger is tested through its full range of movement before the procedure ends
5. A simple dressing is applied, and the patient goes home the same day

Can More Than One Finger Be Affected?

Yes. It is common for trigger finger to affect the ring finger or thumb most often, but more than one finger, or both hands, can be involved, particularly in people with diabetes. If one finger has already been treated and another starts showing the same catching or locking pattern, it is worth an early review rather than waiting for it to become severe, since earlier treatment is generally simpler than treatment for a finger that has already become fixed in a bent position.

Trigger Thumb in Young Children

A related but distinct condition, trigger thumb, can appear in infants and young children, usually noticed as a thumb that is stuck bent at the last joint rather than one that catches during movement. Unlike adult trigger finger, it is not caused by repetitive gripping and is thought to relate to how the tendon developed. Many cases improve with gentle stretching over the first year or two of life, and a paediatric orthopaedic opinion is useful if it persists, since the treatment approach for children differs from that for adults.

Preventing It from Coming Back

There is no guaranteed way to prevent trigger finger, but reducing repetitive gripping strain, taking short breaks during activities that involve a tight grip, and managing diabetes well all help reduce the chance of recurrence. People who ride a two-wheeler through Pune's traffic for long periods, or who do repetitive kitchen or workshop tasks, may notice symptoms easing once the grip load is spread out or the activity is modified.

Hand and wrist problems often overlap. If numbness or tingling in the fingers is also present, it is worth reading about carpal tunnel syndrome, since the two conditions can occur together and are assessed differently.

Life After Treatment

Whether trigger finger settles with simple measures, an injection, or a short procedure, most people return to their normal grip and daily tasks without lasting restriction. The occasional stiffness some people notice in the morning for a few weeks after a procedure usually eases as the hand settles into regular use. Keeping an eye on the same finger, and on the other hand, for early signs of catching gives the best chance of simple, early treatment if it happens again. Most people resume driving, cooking and work tasks within a few days of a release procedure, with full unrestricted grip strength typically returning over the following few weeks as any mild tenderness at the small incision site settles.
