trigger finger
Trigger finger, commonly known as tenosynovitis, is one of the most frequent hand surgery issues. The characteristic “popping” sound and sensation is caused by a narrowing of the tendon sheath in the hand, which results in the finger becoming stuck in a bent position. This condition primarily affects middle-aged women, but younger individuals are also increasingly affected due to the overuse of electronic devices.
Causes of Trigger Finger
Trigger finger develops due to structural and functional changes in the tendon sheaths. These are the channels through which the tendons move. Normally, these channels allow the tendons to glide smoothly. However, when the sheath narrows or the tendon thickens, it hampers the movement of the tendon, leading to the characteristic “popping.”
Common Causes:
- Tenosynovitis (inflammation of the tendon sheath): Inflammation causes swelling inside the sheath, making it difficult for the tendon to glide smoothly.
- Anatomical abnormalities: Nodules or thickenings on the tendon can mechanically obstruct its movement within the sheath.
- Chronic strain: Repetitive hand movements such as writing, typing, or other fine motor tasks can lead to tendon sheath inflammation and narrowing.
- Injuries and healing: Previous hand injuries can result in scar tissue that further narrows the sheath.
Risk Factors:
- Age: Trigger finger is more common in middle-aged and older adults, particularly those whose jobs or hobbies involve intensive hand use.
- Gender: Statistically, women are more frequently diagnosed with trigger finger, especially those who perform regular fine motor hand movements.
- Underlying Conditions: Conditions like diabetes, rheumatoid arthritis, or other autoimmune disorders can increase susceptibility to tissue inflammation and structural abnormalities.
Symptoms of Trigger Finger
Trigger finger, medically termed stenosing tenosynovitis, can cause significant discomfort and pain. Recognizing the common symptoms early is important to manage the condition effectively.
Early Symptoms:
The primary symptom is the locking of the finger in a bent position, which is followed by difficulty in straightening it. Patients often complain of pain in the palm, specifically at the opening of the tendon sheath, where thickening of the tendon and sheath can be felt.
Key Symptoms:
- Tenderness and Pain: Inflammation causes pain near the base of the finger, which can fluctuate throughout the day but is often worse in the morning.
- Swelling: Swelling appears near the base of the fingers, indicating physical changes in the inflamed tendon sheath.
- Popping or Clicking Sound: The thickened tendon passes through the narrowed sheath with a popping sound and sensation, which can be painful.
Worsening Symptoms:
As the condition progresses, finger movement becomes increasingly difficult. Patients may need to use the other hand to bend or straighten the affected finger. When multiple fingers are involved, both hands’ function may be impaired.
Trigger Finger Surgery
When conservative treatments fail, surgery may be necessary to restore full movement and relieve pain. There are two main surgical techniques for treating trigger finger.
Percutaneous Release:
This is a less invasive procedure where the hand surgeon uses ultrasound to guide a needle that releases the constricted tissue around the tendon sheath. This technique doesn’t require an incision, leaving no scar and resulting in a shorter recovery time. However, it may not be suitable for all patients.
Open Surgery:
In most cases, open surgery is the preferred option. Dr. Péter Vancsó, our hand surgeon, makes a small incision on the affected finger and carefully cuts the tendon sheath, allowing the tendon to move freely again. This outpatient procedure typically takes about half an hour, though multiple fingers may extend the surgery time.
After Trigger Finger Surgery
After surgery, patients may experience mild pain and swelling, which can be managed with anti-inflammatory medication and elevating the hand. Physical therapy may also be recommended to promote mobility and reduce swelling. It’s important to avoid heavy hand use, such as lifting heavy objects or repetitive motions, during the first two weeks post-surgery.
Recovery and Daily Activities:
Recovery is usually quick, with most patients returning to their normal routine within about two weeks. Individual recovery times may vary, so it’s crucial to follow regular medical check-ups and a personalized rehabilitation plan.
When is Trigger Finger Surgery Necessary?
Surgery becomes necessary when conservative treatments such as anti-inflammatory medications, rest, and physical therapy do not provide lasting relief. Surgical intervention is recommended when the condition significantly impairs daily activities, such as writing, gripping objects, or performing other manual tasks.
The timing of surgery is crucial, as prolonged symptoms can cause permanent damage to the joints and tendons in the finger. It’s important for patients not to delay consultation, especially when initial treatments are ineffective.
