Prevalence of low back pain after transfemoral amputation related to physical activity and other prosthesis-related parameters

Background: Although clinical experience indicates that prolonged use of a prosthesis after transfemoral amputation (TFA) is related to a higher incidence of low back pain (LBP), few data are available to substantiate this impression. Therefore, in a TFA population, we investigated the prevalence of LBP and its relationship with years since amputation, as well as the level of daily physical activity and other prosthesis-related parameters.Method: Questionnaires were sent to 490 subjects with TFA. Of these, 240 questionnaires could be used for analysis.Results: Trauma and tumours were the most frequent reasons for amputation. The majority of the study group was aged under 30 years at the time of surgery, had been using a prosthesis more than 10 years, and had a moderately active life. Serious LBP (i.e. frequent or permanent LBP) was reported in 26.3% of the participants. No relationship was found between LBP and years since amputation or physical activity.Conclusion: The data show that the prevalence of LB...
