Hello, welcome to the forum. sorry about your daughter's injury. Growth plate injuries are tricky. They often don't show on x rays or mri's and they take a long time to heal. They are still monitoring it, correct? At the time of injury, it is hard to tell how damaged a growth plate is and if it is permanent. Sometimes they follow an injury through growth. Did they recommend physical therapy? Healing time varies but fractures near or over a growth plate can take several weeks to heal.
