Trigger Finger

Trigger finger is a condition where a finger or thumb gets stuck in a bent position and then suddenly pops straight.

It happens when the tendon that controls the finger movement becomes inflamed and cannot smoothly glide through the sheath that surrounds it.

Causes include repetitive gripping, rheumatoid arthritis, gout and diabetes.

Trigger finger can interfere in performing simple tasks such as doing buttons, opening door handles, typing and using a key.
Treatment includes rest, splinting, steroid injections and anti – inflammatory medication.

In severe cases surgery may be required which involves a small incision at the base of the finger through which the tendon sheath can be released to allow the tendon to move more smoothly.
