Trigger finger
Overview
Trigger finger, another painful orthopaedic condition occurs when the finger is bent abnormally in an unusual, trigger-like position. The disorder can affect any finger but commonly affects the thumb and ring finger. Trigger finger occurs when the tendon that has control over the finger cannot move smoothly within the sheath that encompasses it. It develops when a portion of the sheath begins to swell or if a lump develops on the tendon.
Common Signs of Trigger Finger
The condition may be mild or severe, which may result in the following:
- Stiffness in the finger
- Clicking or popping feeling when moving the finger
- Bump and tenderness at the end of the finger
- Locking or catching of the finger in its bent position, which usually pops back into a straight position.
- The finger remains fixed in an abnormally bent position.
Possible Causes of Trigger Finger
Trigger finger occurs due to irritation and inflammation of the tendon sheath. As a result, it becomes more challenging for the tendon to move easily through the sheath. The ongoing irritation can cause a small tissue lump (nodule) to occur on the tendon. This nodule makes it even more difficult for the tendon to move easily.
Risk Factors for Trigger Finger
Potential risks include the following:
- Repeated gripping occurs from repetitive, ongoing hand use, usually due to certain occupations or hobbies.
- Underlying health conditions such as rheumatoid arthritis and diabetes.
Treatment for Trigger Finger
Treatment for the trigger finger differs depending on its extent and duration.
Usually, treatment includes the following:
- Non-steroidal anti-inflammatory medication offers temporary relief from pain and swelling.
- Splinting allows the tendon to rest.
- Stretching enforces enhanced mobility of the finger.
Surgery, while a last resort, is a highly effective option when conservative treatments have proven to be ineffective. An incision is created at the base of the finger through which the restricted part of the tendon sheath is cut open.
Trigger Finger FAQ:
Do you always need surgery for trigger finger?
No, surgery is not always necessary. Many cases improve with non-surgical treatments, such as rest, splinting, anti-inflammatory medication, and steroid injections.
Surgery is usually considered only when:
- Symptoms persist despite conservative treatment.
- Finger locking or pain interferes with daily activities.
Surgical release is highly effective when required, but most patients improve without it.
How long do symptoms of trigger finger last?
Symptom duration varies based on severity and treatment.
- Mild cases may improve within a few weeks with rest and therapy.
- More persistent or severe cases can last several months.
- Prompt management usually speeds recovery and prevents long-term stiffness.
Is trigger finger a serious condition?
Trigger finger is generally not dangerous, but it can be painful and may limit finger movement. If left untreated, the finger can become stiff or locked, making everyday tasks difficult. Early diagnosis and management help relieve symptoms and prevent complications.
