The recovery time for a dislocated hand in a 2-year-old baby depends on the condition of the child, and there are individual differences in the specific time, so it cannot be generalized. If the hand of a 2-year-old baby is closed dislocation, the affected limb should be fixed in a plaster or brace during the acute period by giving a timely manual repositioning, and it usually takes 2-4 weeks for the joint capsule to heal gradually. In the case of open dislocation of the hand, surgical repair is required immediately after the injury to prevent intra-articular infection, and the recovery time is relatively long, and active functional training should be carried out after the surgery to make the joint function return to normal faster. Therefore, parents need to take protective measures when their 2-year-old baby has a dislocated hand to avoid re-dislocation after repositioning; if necessary, it is recommended to go to the pediatric surgery department of a regular hospital for regular review to clarify the recovery of the baby’s dislocated hand.
