Final answer:
Children who cannot understand or follow a prescribed protocol for motion can be initially treated with an immobilization orthosis to strengthen the repair before movement, reducing the chance of rupture.
Step-by-step explanation:
When a child cannot understand or follow a prescribed protocol for motion, they may benefit from using an immobilization orthosis initially. This orthosis helps strengthen the repair before movement, reducing the chance of rupture. An immobilization orthosis is a brace or cast that reinforces the bone structure being supported. It restricts movement and provides stability to the affected area, allowing the bone to heal properly.
