Children thumb tenosynovitis, commonly known as \"congenital thumb trigger finger \", children\" bouncing finger \", refers to the child thumb flexor tendon in the tendon sheath sliding blocked, resulting in the thumb between the joint flexion state, and passive movement will produce a sense of resistance like the trigger and named for a disease. Trigger refers to children with one of the most common bone and joint diseases, usually occurring in their six- to two-year-olds, who are in the developmental stages of fine activity and enjoy exploring the world through finger-touching, grip-holding and other forms of movement.
The cause of the child's trigger finger is not clear at present, some family history, many scholars believe that it may be the thumb flexor tendon sheath congenital stenosis, that is, A1 pulley congenital thickening caused by the tendon in its internal sliding block, over time, sliding blocked flexor tendon proximal fat knots, through the narrow tendon sheath to produce a sound, similar to the trigger and named \"trigger finger \".
Trigger refers to rehabilitation treatment, rehabilitation treatment methods include physical factor therapy, passive drafting, functional exercise, support therapy. Rehabilitation treatment has no invasiveness, no pain, low cost and remarkable curative effect, but it needs the cooperation of parents to carry out family rehabilitation treatment.
If there is no obvious improvement in strict conservative treatment for a period of time, local tenosynovotomy can be performed. The common method of operation is incision, release A1 trochlear, no movement restriction after operation, usually 1-2 weeks after the thumb can restore function.
After the trigger finger is cured, if the thumb is in the flexion position for a long time and the force is excessive, it may cause the recurrence of the trigger finger. Therefore, whether after surgery or conservative treatment, need appropriate finger function exercise, do not use excessive.
Should pay attention to the strength of the hand control, pay attention to appropriate rest. avoid playing games that require thumb force for a long time, such as remote control car, lego building blocks, stickers, etc. If the baby's thumb cannot be actively straightened, do not force straight, but need to parents according to the family rehabilitation guidance for the corresponding treatment.
