Ten-year survival of Finnish lower limb amputees.
Data on mortality for the ten years following lower limb amputation were obtained from all the 16 surgical units in Southern Finland and the National Social Insurance Institution. In Southern Finland during the period 1984-1985, amputations of the lower limb were performed on 705 patients, of whom 382 (54%) were women and 323 (46%) men. The majority of the amputations, 47% were performed for vascular diseases and 41% were performed for diabetes mellitus. The overall survival was 62% at one year after amputation, 49% at two years, 27% at five years and 15% at ten years. The median survival after amputation was 1 yr 5 mth for the women and 2 yr 8 mth for the men. Of the arteriosclerotics, 43% died within one postoperative year while 43% lived longer than two years and 23% longer than five years. The median survival of arteriosclerotics was 1 yr 6 mth. The corresponding figure for patients with diabetes was 1 yr 11 mth. Of the diabetics, 38% died within one postoperative year while 47% lived longer than two years and 20% longer than five years. Of the trauma patients, 86% lived longer than five years and 71% longer than ten years. Of the trans-femoral amputees, 54% lived longer than one year, 36% over two years, 18% over five years and 8% over ten years. The corresponding figures for trans-tibial amputees were 70%, 53%, 21% and 4%. Many elderly vascular and diabetic patients undergoing amputation have a reduced physiological reserve and high mortality. The more proximal the amputation, the greater the risk that the patient will never be able to walk or that the duration of use of the prosthesis will be short. If a prosthesis seems to be a reasonable option for the elderly amputee, any delays in prosthetic fitting should be avoided in older age groups.
