title: Are Canadian prostheses used? A long-term experience.
abstract: The Canadian prosthesis is indicated for the more proximal levels of amputation of the lower limb (very short trans-femoral, hip disarticulation and hemipelvectomy cases); it is frequently rejected by many patients for different reasons (awkwardness, intolerance of the socket, excessive energy expenditure to ambulate among others). The objective was to analyse the use or rejection of Canadian prostheses (n = 23) after an 8-year follow-up study (range: 2 -16 years). The sample consisted of 52% men and 48% women, and the average age at the time of amputation was 52.26 +/- 19.71 SD years (range: 1-74 years). The most frequent aetiology was malignant tumour (56.5%). Eight of the subjects continued to use the prosthesis through the entire study (34.7%). Gender, age, and aetiology were not significant determinants of use. The daily use was 12.5 h per day. The rejection of the Canadian prosthesis was after 20 months of use (range: 2-48 months), and the main reasons were death (all tumour causes), intolerance to the socket, or difficulty in ambulation. In conclusion, many years after their discharge from rehabilitation services, more than one-third of the sample (34.7%) were wearers of the Canadian prosthesis.
