Trigger finger affects millions worldwide, ranking among the top 5 causes of disability in the hand. As an Orthopedic Specialist in Mohali, I’ve seen how this condition—medically known as stenosing tenosynovitis—causes significant discomfort through painful clicking, stiffness, and fingers stuck in a bent position. Women face this challenge six times more frequently than men, particularly between the ages of 40 to 60. Additionally, those with diabetes experience trigger finger at much higher rates—approximately 10% compared to just 2-3% of the general population.

Hand stiffness and finger locking are especially troublesome during morning hours and often worsen after periods of heavy hand use. Certain occupations face greater risks, with farmers, industrial workers, and musicians developing trigger finger more frequently due to repetitive finger movements. The good news, however, is that effective treatments exist—from conservative approaches like splinting and steroid injections to surgical options when needed. In this comprehensive guide, I’ll walk you through everything you need to know about trigger finger, from recognising early symptoms to understanding your treatment options.
What is Trigger Finger?
Stenosing tenosynovitis, commonly known as trigger finger, occurs when a finger becomes stuck in a bent position before suddenly releasing, similar to pulling and releasing a trigger. This condition develops when inflammation narrows the space within the sheath surrounding the flexor tendons that control finger movement.
Trigger finger meaning and overview
Trigger finger happens when bands of tissue called pulleys (specifically the A1 pulley) become inflamed or thickened, making it difficult for tendons to slide smoothly. As your finger bends, the tendon may catch and then suddenly release, creating a distinctive clicking or popping sensation at the base of the affected digit.
Initially, you might notice mild discomfort that gradually worsens. Many patients report that their symptoms are most severe upon waking in the morning. Without treatment, the affected finger may eventually become locked in a flexed position, requiring force to straighten it, and in advanced cases, making it impossible to fully extend.
Difference between arthritis & trigger finger
Although both conditions cause hand pain and stiffness, trigger finger and arthritis are fundamentally different. Trigger finger affects the tendons and their sheaths rather than the joints themselves. Arthritis involves inflammation and breakdown of joint tissues, eventually causing bones to rub against each other across the 27 joints in your hands and fingers.
Furthermore, trigger finger presents with characteristic catching or locking sensations not typically seen in arthritis. You might also feel a small nodule in your palm from the enlarged tendon or thickened pulley – another distinctive feature of trigger finger.
Commonly affected fingers and demographics
Trigger finger shows clear patterns in which digits it affects. The ring finger is most commonly affected, followed by the middle finger, with the thumb close behind. When the thumb is involved, the condition is specifically called trigger thumb.
This condition displays interesting demographic patterns:
- Women develop trigger finger approximately twice as often as men (68% vs. 32%)
- Most cases occur between the ages of 40-60, with an average age of 63 years
- The dominant hand is affected in 70% of cases
- Right-handed individuals experience trigger finger in their right hand 60% of the time
While anyone can develop trigger finger, certain groups face higher risks. The condition affects 2-3% of the general population but jumps to 10-20% among people with diabetes. Other conditions like rheumatoid arthritis, gout, and thyroid disease also increase susceptibility.
Recognising the Symptoms Early
Identifying trigger finger early can help prevent progression to more severe symptoms. The condition typically begins gradually without any apparent injury and may follow periods of extensive hand use.
Early signs of trigger finger
The first indications of trigger finger often include a painful clicking or snapping sensation when bending or straightening your finger. You might notice mild stiffness, particularly in the morning, that gradually improves with movement throughout the day. Many patients report a strange feeling as if something is catching in their finger. These symptoms frequently start subtly and worsen over time if left untreated.
Finger locking and hand stiffness
As trigger finger progresses, the catching sensation becomes more pronounced. Your finger may temporarily lock in a bent position before suddenly popping straight—the characteristic “triggering” that gives this condition its name. Morning stiffness becomes more noticeable, making it difficult to make a fist or grasp objects firmly. In advanced cases, the affected digit may become completely locked in a bent position, requiring you to use your other hand to manually straighten it.
Swollen finger joint with pain
A key physical sign of trigger finger is tenderness or a noticeable bump (nodule) at the base of the affected finger in your palm. This nodule forms where the tendon has become swollen and thickened. Soreness typically intensifies when gripping objects or when pressure is applied to this area. The inflamed tendon struggles to glide smoothly through its sheath, consequently causing pain during finger movement.
When symptoms are worse during the day
Trigger finger symptoms follow distinct patterns throughout the day. The condition is notably worse after periods of inactivity, particularly first thing in the morning. Stiffness and locking tend to improve somewhat with gentle, consistent hand use as the day progresses. Nevertheless, symptoms often intensify during activities requiring firm grasping or pinching motions. Unlike some hand conditions that worsen with overuse, trigger finger is primarily troublesome after rest periods and upon initial movement.
Understanding Causes and Risk Factors
The root cause of trigger finger lies in the mechanical disruption of tendon movement. Understanding why and how this condition develops can help identify those at higher risk.
Inflamed tendon in finger: how it starts
Trigger finger begins when tendons that control your finger movements become irritated and swollen. These rope-like structures normally slide smoothly through a protective tunnel called the tendon sheath. With repeated use or certain health conditions, the tendon or its surrounding sheath becomes inflamed, creating friction during movement. Over time, this constant irritation forms a small lump (nodule) on the tendon. This nodule further complicates movement by getting caught on the A1 pulley (part of the sheath), causing the characteristic catching sensation.
Trigger finger in diabetes and thyroid conditions
People with diabetes face a significantly higher risk—approximately 10% of diabetics develop trigger finger compared to just 2-3% of the general population. Interestingly, research shows the length of time living with diabetes correlates more strongly with trigger finger risk than blood sugar levels. The theory is that chronic high blood glucose creates cross-links between collagen molecules, resulting in collagen buildup in tendon sheaths.
Thyroid conditions likewise increase vulnerability to trigger finger. Studies show trigger finger occurs in 10% of patients with subclinical hypothyroidism. Moreover, hypothyroid patients have the highest prevalence of Dupuytren’s contracture (21.7%), limited joint mobility (8.7%), and carpal tunnel syndrome (30.4%).
Hand pain in manual workers and repetitive strain
Occupations involving forceful, repetitive hand movements significantly increase trigger finger risk. Construction workers and manual labourers who regularly use vibrating power tools often develop this condition. Farmers, industrial workers, and anyone performing strenuous repetitive motions face similar risks. The constant strain causes microtrauma to the tendon-sheath complex, leading to inflammation and eventual tendon adhesion.
Trigger finger in computer users and musicians
Musicians face unique trigger finger risks due to their intensive, precise finger movements. Guitar players frequently develop multiple trigger fingers, sometimes affecting five or six digits simultaneously. One hand surgeon likens the condition to “a trumpet valve sticking,” noting that trumpet players must regularly oil their instrument valves to prevent similar mechanical issues. Computer users who spend hours typing or using a mouse also experience higher rates of trigger finger due to repetitive strain.
Diagnosis and Treatment Options
Diagnosing and treating trigger finger involves a structured approach that varies based on symptom severity and patient-specific factors. Let’s explore the complete treatment pathway from initial diagnosis to surgical intervention.

Trigger finger diagnosis: what to expect
Physicians primarily diagnose trigger finger through a physical examination. During the exam, your doctor will check for tenderness over the flexor tendon, thickening of the tendon sheath, and the characteristic clicking sensation when you bend and straighten your digit. While X-rays are typically unnecessary, ultrasound may occasionally be used to evaluate tendon inflammation and to demonstrate the catching phenomenon during tendon movement.
Non-surgical treatment for trigger finger
Most cases begin with conservative approaches. Effective non-surgical options include:
- Rest and activity modification: Avoiding repetitive gripping and using padded gloves for protection
- Anti-inflammatory medications: Over-the-counter NSAIDs like ibuprofen to reduce pain and swelling
- Gentle stretching exercises: To maintain mobility and decrease stiffness
- Splinting: To immobilise and rest the affected digit
Splint for trigger finger: when and how to use
Splinting works by limiting tendon gliding and reducing inflammation. Research shows that wearing a splint for 6-10 weeks can be remarkably effective—one study found 87% of participants no longer required surgery or injections after completing a splinting regimen. Splints should typically position the metacarpophalangeal joint at 10-15 degrees of flexion. For milder cases, splinting alone may be the initial recommended treatment.
Steroid injections and their effectiveness
Corticosteroid injections into the tendon sheath represent a highly effective first-line intervention. Studies demonstrate an overall success rate of 66-69%. Interestingly, effectiveness varies by digit—the thumb responds best with a 92% success rate. Some patients may benefit from multiple injections, with efficacy increasing from 34% after one injection to 66% after three.
Trigger finger release surgery explained
When conservative treatments fail, surgical release of the A1 pulley becomes necessary. The procedure takes approximately 20 minutes under local anaesthesia on an outpatient basis. Two main approaches exist:
- Open release surgery: A small incision allows direct visualisation and release of the pulley
- Percutaneous release: Using a needle through the skin to divide the pulley, though this carries slightly higher risks
Most patients experience significant improvement after surgery, with a success rate exceeding 90%.

Conclusion
Trigger finger, though painful and frustrating, remains a highly treatable condition when addressed properly. Throughout this guide, we’ve examined how this tendon disorder causes the characteristic catching and locking sensations that affect daily activities. Additionally, we’ve explored the demographic patterns showing that women and diabetic patients face significantly higher risks.
Early recognition of symptoms certainly makes a difference in treatment outcomes. Patients should watch for the initial signs—painful clicking, morning stiffness, and that distinctive catching sensation when bending fingers. Undoubtedly, understanding the underlying causes helps explain why certain groups experience higher rates of trigger finger. Manual workers, musicians, and computer users face elevated risks due to repetitive strain, while diabetes and thyroid conditions create physiological vulnerabilities.
The good news? Most patients respond well to conservative treatments. Splinting alone resolves many mild cases, while steroid injections prove effective for moderate symptoms, especially in the thumb. Nevertheless, surgical intervention remains a reliable option when other approaches fail, with success rates exceeding 90%.
As a physician who has treated countless trigger finger cases, I emphasise the importance of seeking treatment rather than enduring the discomfort. Though frustrating, this condition rarely causes permanent damage if addressed properly. Therefore, anyone experiencing symptoms should consult with a Hand Specialist in Mohali for Finger Pain to determine the most appropriate treatment path. With proper care, most patients return to normal hand function, free from the pain and limitations this condition can cause.

FAQs
Q1. What is the most effective treatment for trigger finger?
A1. The most effective treatment for trigger finger depends on the severity of the condition. For mild cases, conservative approaches like splinting and anti-inflammatory medications may suffice. Corticosteroid injections are highly effective for moderate cases, especially in the thumb. When conservative treatments fail, surgical release of the A1 pulley is considered the gold standard, with success rates exceeding 90%.
Q2. Can vitamin deficiencies contribute to trigger finger?
A2. While vitamin deficiencies are not typically considered a primary cause of trigger finger, some research suggests that severe vitamin B6 deficiency may contribute to hand and finger issues. However, trigger finger is more commonly associated with factors like repetitive strain, diabetes, and certain occupations rather than specific vitamin deficiencies.
Q3. Are there any topical treatments that can help with trigger finger?
A3. Some topical treatments, such as diclofenac gel (a topical NSAID), may help reduce pain and inflammation associated with trigger finger. However, these are generally considered supplementary treatments and may not address the underlying mechanical issue causing the condition.
Q4. How long does it take for trigger finger to improve with treatment?
A4. The timeline for improvement varies depending on the treatment method. Splinting may show results after 6-10 weeks of consistent use. Steroid injections can provide relief within a few days to a few weeks. Surgical treatment often leads to immediate improvement in movement, with full recovery typically occurring within a few weeks to months.
Q5. Who is most at risk of developing trigger finger?
A5. Trigger finger is more common in women, particularly between the ages of 40-60. People with diabetes face a significantly higher risk, with about 10% developing the condition compared to 2-3% of the general population. Additionally, individuals in occupations involving repetitive hand movements, such as musicians, manual labourers, and frequent computer users, are at increased risk of developing trigger finger.
