Welcome to HealthcareMagic forum.
Minor displacement of tibia
can occur spontaneously in healing fractures
of tibia but if there is gross rotation or bending then you need to check with her surgeon or physiotherapist for minimizing movement and stress
at fracture site by appropriate immobilization technique .
As of now it doesn't seem much worrisome as the first X-ray was fine and i assume the fracture callus
has formed( healing started).most fractures in children have excellent recovery as their bones are growing and remodeling throughout childhood .
Just make sure you ask her doctor for appropriate position of limb , movements to be avoided and physical therapy
exercises for faster recovery.
As its already five weeks now the fracture should have almost healed by now.
Hope I have answered your query.
Wishing your daughter a speedy and complete recovery.
