The operation to transplant the hand of a dead man on to the arm of Perth amputee Mr Clive Hallam was unlikely to succeed, one of Melbourne's leading microsurgeons predicted yesterday. An international team of surgeons, led by Australia's Professor Earl Owen, performed the 11-hour operation on the former truck driver, 48, at a medical centre in France.Professor Wayne Morrison, the chief of microsurgery at St Vincent's Hospital, said the successful transplantation of vital organs would be significant and exciting. But Professor Morrison said there was not, to his knowledge, sufficient evidence available about the immuno-suppressant drugs required to confidently predict the outcome of such surgery.
