Once in the university hospital of Kraków his CT scan showed a fracture of C1 .
This needed urgent surgery to fuse his spine from C1-4.
He was transferred to intensive care and kept in a medically induced coma for two weeks.
His recovery was far from straight forward and he developed a pneumonia and then had a tracheostomy to aid weaning.
Finally he was fit enough for the transfer home, and was flown back with a medical escort and oxygen for the flight.
