Googled it and got to know this:
Hairline fractures are often caused by overuse or repetitive actions when microscopic damage is done to the bone over time.
Her finger must have been injured before too as one pull can't cause a fracture all of a sudden. May be I'm wrong but the pull was not that dangerous or harmful.
I think she was hurt when she was banging on those cardboards continuously
