Trigger Finger: Causes, Symptoms, and Treatment Options

Trigger finger is a common condition that affects hand mobility and causes pain, stiffness, and difficulty in moving the fingers. This condition occurs when the flexor tendons in the fingers or thumb become inflamed, which can cause the finger to lock or strain when bending or straightening. This condition can have quite an impact on daily activities, especially for those individuals who use carry out tasks with repetitive hand movements. Understanding the causes, symptoms, and available treatment options can help in managing and preventing trigger finger effectively. This article dives into all these details of trigger finger to help you understand this condition better.

What Is Trigger Finger?

Trigger finger is known medically as stenosing tenosynovitis. This condition affects the tendons in the fingers or thumb, causing them to lock or catch when bent. The affected finger may get stuck in a bent position before suddenly straightening, similar to a trigger being released, hence the name trigger finger. This condition is most commonly seen in individuals who frequently perform repetitive hand movements. If you are suffering from wrist pain, read more about wrist injury treatment.

Causes of Trigger Finger

Trigger finger occurs when the flexor tendons in the finger or thumb and the surrdounding sheath gets inflamed or thickened. This causes pain and smooth movement restriction. Some of the most common causes of trigger finger are listed below:

• Repetitive Hand Use – Activities that involve frequent gripping or repetitive hand motions can increase the risk.
• Medical Conditions – People with diabetes, rheumatoid arthritis, or gout have a higher likelihood of developing trigger finger.
• Gender and Age – Women, particularly those over 40, are more prone to developing this condition.
• Occupational Risk – Jobs that require extensive gripping, such as farming, construction work, and musicianship, can lead to trigger finger.
• Trauma or Injury – Direct injury to the hand or fingers may trigger inflammation of the flexor tendons and contribute to the condition.

Symptoms of Trigger Finger

Trigger finger symptoms may develop gradually or suddenly, depending on the severity of the condition. Common signs of trigger finger include:

• Finger Stiffness – You may notice stiffness in finger, especially in the morning.
• Clicking or Popping Sensation – You may hear and feel a distinct snapping or popping feeling when moving the affected finger.
• Pain and Tenderness – You may feel pain, tenderness, and discomfort at the base of the affected finger or thumb.
• Locking of the Finger – In more severe cases, your finger may become stuck in a bent position and require manual assistance to straighten. This is called finger locking.
• Swelling or Lump Formation – If left untreated for long, you may notice a tender lump developing at the base of the finger due to thickened tendon tissue.

How is Trigger Finger Diagnosed?

A healthcare professional typically diagnoses this condition based on the following tests and exams:

1. Medical History – Your doctor will take your detailed medical history and discuss symptoms with you. He will also inquire about any activities that may have led to the condition.
2. Physical Examination – The doctor will also carry a physical exam to check for signs such as tenderness, clicking, or difficulty moving the finger.
3. Imaging Tests (if needed) – Although not typically ordered, in some cases the doctor may order diagnostic imaging tests like ultrasounds or MRI scans to further assess the case or rule out other conditions. 

Trigger Finger Treatment In Singapore

The treatment for trigger finger in Singapore depends on the severity of symptoms and how much they interfere with daily activities. These may include conservative and surgical treatment options. 

Non-Surgical Treatment Options

Typically, the first line of treatment for trigegr finger is conservative measures. Your doctor may recommend the following modalities:

• Rest and Activity Modification – This involves reducing activities that strain the fingers and giving them adequate rest. 
• Splinting – The doctor may advise you to wear a splint at night to keep the finger in an extended position. This can help prevent locking and ease the symptoms over time.
• Stretching Exercises – Gentle hand exercises can help improve flexibility and reduce stiffness in the finger joints.
• Medications – In case of pain, the doctor may prescribe nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen to help reduce pain and swelling.
• Steroid Injections – In some cases, your doctor may administer a corticosteroid injection into the tendon sheath directly. This helps reduce inflammation and restores movement, often resulting in long-term pain relief. Some patients may require more than one injection for sustained results.
• Physical Therapy – Physical therapy for trigger finger can help maintain mobility and prevent stiffness from worsening. This includes targeted exercises for trigger finger and various hand therapy techniques.
• Cold and Heat Therapy – Applying ice packs to the affected finger can reduce swelling, while warm compresses may help improve circulation and flexibility.
• Ergonomic Adjustments – Using ergonomic tools and adopting hand-friendly modifications into your daily activities can help alleviate finger strain and reduce symptoms’ severity.
• Massage Therapy – Gentle massage of the affected finger can improve blood circulation, relieve tension, and promote healing in the affected tendon area.

Surgical Treatment Options

If conservative treatments fail, an orthopaedic specialist may recommend surgery. For treating a trigger finger surgically, the most common procedure is trigger finger release surgery. This procedure can be performed in two ways:

• Percutaneous Release – During this procedure, the surgeon uses a needle to break apart the constricted tendon sheath. This is a minimally invasive procedure performed under local anaesthesia.
• Open Surgery – In the case of severe or recurrent cases, the surgeon may opt for an open surgery. In this procedure, the surgeon makes a small incision to release the affected tendon, allowing smoother movement. The incision is closed through sutures at the end. 

Both procedures are typically performed under local anaesthesia and have high success rates with minimal recovery time.

Post-Surgical Care and Rehabilitation

Recovery from surgery of trigger finger requires appropriate post-care that includes:

• Hand Therapy – Exercises and therapy to restore flexibility and strength.
• Pain Management – Over-the-counter pain relievers and ice therapy may help manage post-surgical discomfort.
• Wound Care – Keeping the incision clean and dry to prevent infection.
• Gradual Resumption of Activities – Avoiding strenuous hand activities during the healing period.

Preventing Trigger Finger

Although not all cases of this condition can be prevented, there are some measures that you can take to reduce the risk of getting it.

• Avoid repetitive gripping – Take frequent breaks when performing tasks requiring constant hand use.
• Use ergonomic tools – If you do activities that require repetitive hand and finger movements, then try to choose ergonomic tools and equipment that minimise strain on the hands.
• Perform hand exercises – Regular stretching and strengthening exercises can maintain finger flexibility.
• Manage underlying conditions – Although underlying medical conditions cannot directly cause trigger finger, they can exacerbate its symptoms or increase your risk of getting it. For example, keeping diabetes and arthritis under control may reduce inflammation and tendon issues, helping you prevent trigger finger.

When to See a Doctor For Trigger Finger

Although trigger finger does not pose any immediate danger, you may opt to seek medical attention if:

• The affected finger is painful and swollen.
• The locking of the finger is frequent and affects daily activities.
• Non-surgical treatments do not provide relief.

Conclusion

Trigger finger is a common yet treatable condition that can cause discomfort and interfere with hand function. However, with early intervention through rest, splinting, or steroid injections, you can prevent the symptoms from worsening. In severe cases, surgical release provides a long-term solution for trigger finger with minimal downtime. If you experience persistent symptoms, consult a healthcare provider for appropriate management and care.
