Why is my babys thumb bent?

Congenital Trigger Thumb

A trigger finger or thumb happens when trying to bend or straighten the finger or thumb. It locks or catches and does not move freely. In children, it is often first seen when the child is older than 1 year of age.

Causes?

Pediatric trigger thumb occurs by chance and is not related to other disorders.

A band of tissue called a tendon connects the thumb to a muscle in the forearm. Sometimes in children, the tendon grows faster than the protective sheath that surrounds it. The sheath becomes tight, preventing the tendon from gliding easily inside it. The tendon may become swollen and make it difficult (or impossible) for your child to fully extend their thumb.

Treatment?

In a small number of children, trigger thumb gets better on its own, without treatment. The chance of this decreases as children get older. Because of this, surgery is recommended for trigger thumbs in children

older than 2.

Surgery takes about 30 minutes under general anesthesia. During the surgery, the surgeon makes a small cut in the tendon sheath so that the tendon can move smoothly.

After surgery, your child will probably have to wear a soft bandage for one to two weeks.
