title: Lower limb amputee survival.
abstract: A total of 1710 primary amputees have been studied over a 25 year period and their survival time has been calculated. These were all consecutive primary lower limb amputees admitted to the Dundee Limb Fitting Centre during the period 1965-1989. Overall, the median survival was 4 yr 9 mth for the below-knee amputee (1019 patients) and 4 yr 3 mth for the above-knee amputee (586 patients). The vascular related amputees had an overall median survival of 4 yr. In the two decades 1970-1979 and 1980-1989 there were significant differences between the survival time of the below-knee and above-knee amputee. The survival of the amputee has increased during the two decades from 3 yr 6 mth to 6 yr 6 mth (p greater than 0.001). For the first decade male above-knee and male below-knee amputee median survival was 3 yr 1 mth and 3 yr 11 mth respectively and for the second the survival was 5 yr 9 mth and 6 yr 11 mth for these levels of amputation. For 1970-1979 no significant differences were found between male and female peripheral vascular disease (PVD) and diabetes mellitus related amputee survival. For 1980-1989 significant differences were found between PVD related male above-knee amputees (3 yr 10 mth) and male below-knee amputees (6 yr 7 mth) (p greater than 0.01). Similar results were found for the female patients. Operative mortality was found to be 5% over the period 1975-1989 which compared favorably with previous studies.
