Doctor recalls amputation with pocket knife in Canterbury quake
She amputated his legs with a pocket-knife and hacksaw as the aftershocks continued. On the afternoon of 22 February urologist Dr Lydia Johns Putra was on a lunch break with a group of other doctors who had gathered for a conference at Christchurch's convention centre. A brisk walk away financial adviser Brian Coker was in the Pyne Gould building and was also going to head out for lunch. He was on the first floor landing and about to go downstairs, when he was showered in tiles and debris as the quake hit and he was swept off his feet by a cascading concrete wall.
