Trigger Finger
Trigger finger, medically known as stenosing tenosynovitis, occurs when a finger gets stuck in a bent position and then snaps straight. This condition is caused by inflammation and narrowing of the tendon sheath, which affects the smooth gliding of the tendon.
It often results in pain, stiffness, and a sensation of popping or clicking when moving the finger. Trigger finger can be treated with methods such as splinting, corticosteroid injections, or surgery to release the tendon.
Symptoms of trigger finger include:
- Finger locked in a bent position, snapping straight upon extension.
- Pain and discomfort in the affected finger.
- Morning stiffness.
- Popping or clicking sounds when moving the finger.
Trigger finger can be caused by a variety of factors:
- Repetitive gripping motions which strain the flexor tendons.
- Inflammation and constriction of the tendon sheath.
- Medical conditions such as diabetes or rheumatoid arthritis which are linked to increased risk.
- Genetic predisposition which may make some individuals more susceptible to the condition.
What are the treatment options for trigger finger?
- Rest and activity modification: Avoiding activities that strain the affected finger.
- Splinting: Wearing a splint to keep the affected finger extended and relieve tension.
- Exercises: Stretching and strengthening exercises to improve mobility.
- Anti-inflammatory medications: Such as ibuprofen to reduce pain and swelling.
- Corticosteroid injections: To reduce inflammation in the tendon sheath.
- Surgery: Surgical release of the constricted section of the tendon sheath if other treatments don't relieve symptoms.
Reasons for minimal anesthesia during finger surgery
Minimally invasive surgery with local anesthesia is often chosen for finger surgeries due to several key benefits:
- Reduced Pain and Discomfort: Local anesthesia limits pain during and immediately after the procedure without the side effects of general anesthesia.
- Faster Recovery: Smaller incisions and localized anesthesia contribute to quicker healing and shorter hospital stays.
- Lower Risk of Complications: With smaller incisions and local anesthesia, the risks associated with surgery, such as infections and bleeding, are minimized.
- Increased Precision: Minimally invasive techniques can provide surgeons with better precision, especially in delicate areas like the fingers.
- Convenience: Patients usually remain awake and can avoid the grogginess and recovery often required after general anesthesia, allowing them to return home the same day.
What are the surgical procedures for treating trigger finger?
Trigger finger surgery involves releasing the constricted tendon sheath to enable free movement of the tendon. It can be done via open surgery, where a small incision is made at the base of the finger to cut the tendon sheath, or through percutaneous surgery, which uses a needle but no incision, reducing scarring and recovery time.
The procedure is generally quick, performed under local anesthesia, and allows for immediate finger movement post-surgery with full recovery typically within two weeks.
