“Having reviewed all of the evidence I am satisfied on the balance of probabilities that there is a continuum…of significant back problems in this case arising from the serious fall which constituted the 1998 accident and which continued after his two visits in 7/98 to the osteopath and which ultimately led to the 2000 fall down the stairs, and that but for that accident the fall would not have happened. This was a man who had not experienced back problems until 6/98, and then did so. These worsened after the apparently more minor accident of 5/99 and led in time to the twinge which caused his fall down the stairs in 2000.”
