Although the incidence of pediatric trigger finger is high, there are still many misconceptions about it in the medical community. It is not uncommon for medical personnel, especially in primary care institutions, to misdiagnose and mistreat children because of a lack of knowledge about the disease, resulting in even residual joint dysfunction. Inappropriate rubbing by parents of some children leads to further hyperplasia, hypertrophy and narrowing of the flexor tendon sheath. Long-term flexion contracture makes the metacarpophalangeal joint hyperextended and subluxed, and may also affect the development of the thumb. Clinical manifestations: 1, mostly seen in the thumb, manifested as flexion of the interphalangeal joint, which cannot be straightened. 2. Thickened tendons can be palpated at the metacarpophalangeal joints, such as small swellings, which move with the flexion and extension of the fingers and sometimes have pressure pain. 3.Some children usually do not show symptoms at birth, but commonly show the inability to straighten the finger flexion at the age of 6 months to 2 years. 4. Congenital pediatric trigger finger mostly occurs unilaterally, but occasionally can occur bilaterally, often because parents unintentionally find that the child’s thumb cannot be actively straightened and come to the clinic. Treatment: There is a great deal of plasticity in children. There is no need to rush to surgical treatment. Help the child to move the thumb frequently and straighten it passively to correct the bending. It is a good idea to make a splint-like thing to hold the thumb in a straightened position during the day. The easiest way to do this is to use a small wooden spoon with ice cream and some band-aids to hold it in place. Each parent can come up with their own suitable solution. Especially at night, it should be fixed on. During the day the child plays and it may come loose, but of course it does not have to be fixed 24 hours a day, all the time required. Pediatric trigger finger can partially heal on its own. Those with mild symptoms can be observed first and often help the child to move the thumb, straighten it passively and correct the bending condition. A small number can heal. With the above conservative treatment, if straightening is still not possible after 2-3 years of age, surgery may be considered. This is because it may affect the development of the child’s fingers as they get older. Surgery is simple, and loosening the tendon sheath is sufficient. There is a potential risk of damage to the tendon and nerve. The stenosis must be loosened thoroughly during surgery to avoid damage to the vascular nerves, and functional exercises need to be strengthened after surgery to avoid recurrence of adhesions.
