Background: The aim of this study was to determine the outcomes of a contemporary amputation series. Methods: A retrospective audit of 87 cases of major lower limb amputation from January 2000 to December 2002 from the Department of Vascular Surgery, Royal Perth Hospital, was conducted. Results: The mean age of the study population was 70.1 ± 14.3 years; the male : female ratio was 3.35:1. Comorbid problems included diabetes (49.4%), smoking (81.6%), hypertension (77.0%), ischaemic heart disease (58.6%), stroke (25.3%), raised creatinine level (34.5%) and chronic airway limitation (25.3%). Preamputation vascular reconstructive procedures were common, 34.5% in a previous admission and 23.0% in the same admission. The main indication was critical limb ischaemia (75.9%) followed by diabetic infection (17.2%). There were 51 below‐knee (58.6%), 5 through‐knee (5.7%) and 31 above‐knee (35.6%.) amputations. The below‐knee amputation to above‐knee amputation ratio was 1.65:1. The overall wound infection rate was 26.4%; the infection rates for below‐knee (29.4%) and above‐knee (22.6%) amputation did not differ significantly ( P = 0.58). Revision rates were 17.6% for below‐knee, 20% for through‐knee and none for above‐knee amputations. Twenty patients (23.0%) underwent subsequent contralateral amputation. Thirty‐nine patients (44.8%) were selected as suitable for a prosthesis by a rehabilitation physician; 31 (79.5%) used the prosthesis both indoors and outdoors and 6 (15.4%) used it indoors only within 3 months. Cumulative mortality at 30 days, 6 months, 12 months and 24 months was 10.1, 28.7, 43.1 and 51.7%, respectively. Conclusion: This series agrees with the current published work in finding that patients undergoing major lower limb amputation are older, with a high prevalence of comorbid conditions. Successful prosthesis rehabilitation depends on patient selection and a multidisciplinary approach. Despite a low immediate mortality, the overall long‐term results of lower limb amputation remain dismal.
