Trigger finger is a condition in which one of your fingers gets stuck in a bent position. Your finger may bend or straighten with a snap — like a trigger being pulled and released. Trigger finger is also known as stenosing tenosynovitis. It occurs when inflammation narrows the space within the sheath that surrounds the tendon in the affected finger. If trigger finger is severe, your finger may become locked in a bent position. Trigger finger treatment varies depending on its severity and duration. Medications Nonsteroidal anti-inflammatory drugs — such as ibuprofen or naproxen — may relieve the pain but are unlikely to relieve the swelling constricting the tendon sheath or trapping the tendon. Therapy Conservative noninvasive treatments may include: Rest. Avoid activities that require repetitive gripping, repeated grasping or the prolonged use of vibrating hand-held machinery until your symptoms improve. If you can't avoid these activities altogether, padded gloves may offer some protection. A splint. Your doctor may have you wear a splint at night to keep the affected finger in an extended position for up to six weeks. The splint helps rest the tendon. Stretching exercises. Your doctor may also suggest gentle exercises to help maintain mobility in your finger. Surgical and other procedures If your symptoms are severe or if conservative treatments haven't helped, your doctor might suggest: Steroid injection. An injection of a steroid medication near or into the tendon sheath may reduce inflammation and allow the tendon to glide freely again. This is the most common treatment, and it's usually effective for a year or more in most people treated. But sometimes it takes more than one injection. For people with diabetes, steroid injections tend to be less effective. Percutaneous release. After numbing your palm, your doctor inserts a sturdy needle into the tissue around your affected tendon. Moving the needle and your finger helps break apart the constriction that's blocking the smooth motion of the tendon. This treatment may be done under ultrasound control, so the doctor can see where the tip of the needle is under the skin to be sure it opens the tendon sheath without damaging the tendon or nearby nerves. This procedure is usually done in the doctor's office or in an office procedure room. Surgery. Working through a small incision near the base of your affected finger, a surgeon can cut open the constricted section of tendon sheath. This procedure is usually done in an operating room.
