Background Limb salvage for severe trauma has replaced amputationas the primary treatment in many trauma centers. However, long-termoutcomes after limb reconstruction or amputation have not beenfully evaluated.
Methods We performed a multicenter, prospective, observationalstudy to determine the functional outcomes of 569 patients withsevere leg injuries resulting in reconstruction or amputation.The principal outcome measure was the Sickness Impact Profile,a multidimensional measure of self-reported health status (scoresrange from 0 to 100; scores for the general population average2 to 3, and scores greater than 10 represent severe disability).Secondary outcomes included limb status and the presence orabsence of major complications resulting in rehospitalization.
Results At two years, there was no significant difference inscores for the Sickness Impact Profile between the amputationand reconstruction groups (12.6 vs. 11.8, P=0.53). After adjustmentfor the characteristics of the patients and their injuries,patients who underwent amputation had functional outcomes thatwere similar to those of patients who underwent reconstruction.Predictors of a poorer score for the Sickness Impact Profileincluded rehospitalization for a major complication, a low educationallevel, nonwhite race, poverty, lack of private health insurance,poor social-support network, low self-efficacy (the patient'sconfidence in being able to resume life activities), smoking,and involvement in disability-compensation litigation. Patientswho underwent reconstruction were more likely to be rehospitalizedthan those who underwent amputation (47.6 percent vs. 33.9 percent,P=0.002). Similar proportions of patients who underwent amputationand patients who underwent reconstruction had returned to workby two years (53.0 percent and 49.4 percent, respectively).
Conclusions Patients with limbs at high risk for amputationcan be advised that reconstruction typically results in two-yearoutcomes equivalent to those of amputation.
