What is stenosing tenosynovitis in children

If a child suffers from stenosing tenosynovitis, it means serious damage to the child's body, and if it is not effectively treated, it will cause disability. Therefore, for many children with this disease, parents want to fully understand what stenosing tenosynovitis is in children. The following is a detailed introduction so that you can have a comprehensive understanding.

"Snapping fingers" in children, also known as stenosing tenosynovitis or trigger finger, is a common congenital malformation in children. Because the flexor tendons of the fingers are located at the distal end of the metacarpophalangeal joints, they are constricted by the stenosing fibrocartilaginous lesions of the tendon sheath, causing the proximal tendons to thicken or become nodular, making the interphalangeal joints flexed and unable to be actively straightened, causing pain or snapping during passive stretching.

Children with snapping fingers generally do not show symptoms at birth. It is common for the fingers to flex and cannot be straightened when they are around 6 months to 2 years old. The most common sites are the metacarpophalangeal joints of the second and third fingers of the thumb. A round raised nodule can be felt, with slight tenderness. There is a bouncing sensation when flexing and extending the fingers, while the interphalangeal joints are in a fixed flexed state, and there is a snapping sensation when moving and stretching.

Since congenital tendon sheath stenosis cannot heal itself and may affect finger development in the future, treatment should be given as early as possible. Generally speaking, conservative treatment is not effective, while surgery is effective. The operation should be performed through a transverse incision at the palm side of the metacarpophalangeal joint, and the narrow tendon sheath should be cut longitudinally to allow the enlarged tendon to pass through. During the operation, the stenosis must be completely loosened to avoid damage to blood vessels and nerves. Functional exercises should be strengthened after the operation to avoid recurrence of adhesions.

Stenosing tenosynovitis in children (trigger finger) refers to the thickening of fibers at the opening of the flexor tendon sheath in children, which makes it impossible for the thickened tendon to pass through, resulting in the inability to straighten the fingers.

After fully understanding the above content, I believe that many parents have a comprehensive understanding of childhood stenosing tenosynovitis. After a comprehensive understanding, in order to prevent this disease from causing serious harm to the child's body, it is necessary to go to a regular hospital as soon as possible after a comprehensive understanding and receive comprehensive treatment to allow their children to recover as soon as possible.
