Mrs Jeffries wants an apology from the school, which she alleged was not happy with her after Crystal's late father had a non-Catholic funeral.
St Peter's School principal David Olivier said Mrs Jeffries' claims were outrageous, adding Crystal had never informed teachers or asked to call home.
"She told the counsellor she had a headache and had fallen off a trampoline the day before."
Crystal was told to visit the sick bay but Mr Olivier said she went back to class instead. Crystal's 3km walk home usually took an hour. That day, it took three times as long with Crystal hunched over in what she described as agonising pain.
"I got home ... Mum swung the door open and said 'Oh my God, what is wrong with you'?"
Mrs Jeffries rushed her daughter to Palmerston North Hospital where she was X-rayed and discharged but then received frantic calls soon after for them to return.
The X-ray showed a crush fracture at Crystal's C7 vertebral body, near the bottom of her neck. Mrs Jeffries is appalled the first visit failed to establish the injury.
Months later, Crystal was still having trouble. In August, an MRI scan at Palmerston North Hospital went wrong when an intravenous lure caused sudden paralysis in Crystal's left forearm. This was later assessed by a neurologist as "a possible inadvertent injection" of a nerve near her elbow.
Since then, Mrs Jeffries said Crystal's pain had intensified and she was often bedridden.
MidCentral DHB confirmed Mrs Jeffries had complained about Crystal's care last year. Lyn Horgan, of MidCentral DHB, said there was agreement to put the complaints on hold at the end of 2011 for two months while Crystal was in Starship. The DHB had received no further communications or requests for financial compensation from Mrs Jeffries.APN News & Media
