Treating trigger finger with a splint involves strapping the affected finger to a plastic splint, which restricts movement to help alleviate the symptoms, says the National Health Service of United Kingdom. Individuals may use a splint overnight to ease severely stiff fingers in the morning.
Doctors can advise on how long a patient should continue with the splint treatment. Splints can be helpful for some patients with a trigger-finger condition, but there are usually better alternatives, especially for the long term, state the NHS. Other treatments for trigger finger include corticosteroid injections, which reduce tendon swelling, and surgery, which entails cutting through the afflicted section of the tendon sheath. Both the injection and surgery options work by allowing the tendon to move freely again.
