Primary survival and prosthetic fitting of lower limb amputees.

During the period 1984-1985 amputation of the lower limb at a level potentially requiring a prosthesis was performed on 577 patients in 16 operative units. The mean age was 75.7 years for females and 68.1 for males. The most common site of the amputation was above the knee (49.9%). The majority of amputations (93.8%) were performed for vascular diseases and diabetes. Survival figures showed that 25.5% of amputees died within 2 months of amputation, 60.7% were alive after one year and 43.2% after two years. Out of a total of 577 patients, 26.9% were fitted with a prosthesis. Out of below-knee and above-knee amputees surviving over 2 months, 61.5% and 27.2% respectively were fitted with a prosthesis. There were markedly fewer prosthetic fittings in the over-60 age group. Diabetic patients of both sexes were fitted with a prosthesis more often than arterio-sclerotic patients. Among tumour patients 82.4% received a prosthesis. In the study area more emphasis must be put on the concept of preserving the knee joint and preoperative assessment of vascular patients for selection of amputation level. Every effort must be made to avoid delay in the postoperative mobilization and rehabilitation. Prosthetic fitting of amputees could be improved by better liaison between surgical unit and specialized rehabilitation unit and by closer team approach of amputee care.
