“…Torburn et al [23] found that individuals with traumatic TTA were of better physical fitness because their amputations were not due to medical conditions or behaviors that typically affect metabolic rate (e.g., diabetes, peripheral vascular disease, smoking [24]). In the military, a majority of amputations are traumatic in nature.…”

Abstract-Previous literature reports greater metabolic demand of walking following transtibial amputation. However, most research focuses on relatively older, less active, and often dysvascular amputees. Servicemembers with traumatic amputation are typically young, fit, and highly active before and often following surgical amputation of their lower limb. This study compared the metabolic demand of walking in young, active individuals with traumatic unilateral transtibial amputation (TTA) and nondisabled controls. Heart rate (HR), rate of oxygen consumption, and rating of perceived exertion (RPE) were calculated as subjects walked at a self-selected velocity and at five standardized velocities based on leg length. The TTA group completed a Prosthetics Evaluation Questionnaire. Oxygen consumption (p = 0.89), net oxygen consumption (p = 0.32), and RPE (p = 0.14) did not differ between groups. Compared with controls, HR was greater in the TTA group and increased to a greater extent with velocity (p < 0.001). Overall, the TTA group rated their walking abilities as high (mean: 93% out of 100%). This is the first study to report equivalent metabolic demand between persons with amputation and controls walking at the same velocity. These results may reflect the physical fitness of the young servicemembers with traumatic amputations and may serve to guide outcome expectations in the future.

“…The onset of DTI strongly depends on the geometrical and biomechanical characteristics of the bone-muscle interface (Gefen, 2007a, b), which differ widely across individual TTA patients due to different surgical techniques, level of amputation, muscle atrophy and scarring (Portnoy et al, 2007). Since approximately 80% of lower limb amputees suffer peripheral vascular disease, diabetes or both (Kulkarni et al, 2006), the neuropathy associated with these diseases prevents patients from detecting pain and injury to their residual limb. Presently, there is paucity of information on mechanical conditions in the residual limb during load-bearing.…”

“…From historical cohort studies the patient survival rate after a lower-limb amputation because of vascular problems is clearly moderate to low over time [1][2][3][4][5][6][7][8][9][10][11][12]. However, prospective studies on lower-limb amputees seldom report their survival rates, inclusion and exclusion criteria, and/or referral and dropout rates (death included) [13][14][15][16][17][18][19][20].…”

Abstract-This study quantified selection by analyzing the survival rate of the participants and nonparticipants in a 4-year prospective, multicenter cohort study. In addition, the differences between these groups were analyzed. Surgeons of six hospitals in the northern Netherlands referred, in total, 225 patients to the study. Of these patients, 60% (n = 134) participated in the prospective study by filling in questionnaires; the others (nonparticipants) were followed over time through their records. No significant differences were found in sex and level of amputation between participants and nonparticipants; however, of the two groups, nonparticipants were significantly older. Reason for amputation was peripheral vascular disease (PVD) for 67% (n = 90) of the participants and 82% (n = 75) of the nonparticipants. The mean survival time of the participants and nonparticipants was 36.1 and 29.6 months, respectively. Within PVD, the mean survival time of participants and nonparticipants was 34.4 and 27.6 months, respectively. To summarize, our article gives an overview of the survival rates in a prospective study on patients scheduled for a limb amputation. Our study sample was biased by selection and death. Participants were generally healthier than nonparticipants.
