When your finger or thumb locks or catches when you bend it towards your palm, this is known as trigger finger. Common symptoms of trigger finger are pain and discomfort, visible lumps at the finger’s base, stiffness and clicking.
The exact cause for trigger finger is still unknown, yet certain things may increase the likelihood of you developing the condition. These include: rheumatoid arthritis, diabetes, overactive thyroid and carpal tunnel syndrome.
A consultation with your doctor will determine what treatment is most suitable for you. Some cases of trigger finger heal by themselves or can be treated through medication, injections or splinting.
In more serious cases, you may need to have open or percutaneous surgery. Open surgery will involve a doctor making an incision into your palm to release the tendon by dividing the ligament where the tendon is catching. Percutaneous surgery involves the doctor using a needle to divide the ligament that is restricting the tendon. Percutaneous surgery leaves no scars or wounds as no incisions are needed.
A typical procedure lasts 20 minutes and most patients will be put under local anaesthetic for the duration. After the surgery you should be able to move your finger immediately but may experience some pain or tenderness in the finger.
The dressings can be removed after a few days and full movement will return within a fortnight.
