Final answer:
Immobilization is essential for children who have suffered fractures, sprains, or dislocations, as it supports the healing process and prevents further injury.
Step-by-step explanation:
Immobilization is necessary for children who have fractures, sprains, and dislocations. These injuries crucially require immobilization to prevent further damage and to start the healing process. Fractures vary in complexity and may be treated with closed or open reduction, with the healing process involving the formation and unification of calli through bone remodeling. Sprains involve ligament injury and also necessitate immobilization for proper recovery.
Similarly, dislocations, which denote an abnormal separation in a joint, require immobilization to allow for the realignment of the joint and healing. Given the severity and potential complications associated with these injuries, professional medical treatment is essential.
