Abstract

Background: Despite limited data demonstrating altered hemodynamics in the lower extremities (LEs) among the population with spinal cord injury (SCI) and increased frequency of peripheral arterial disease (PAD), epidemiologic data are limited for amputations, a potential consequence. This study investigates the association of amputation due to vascular complications as a secondary outcome measure within the SCI population.

Methods: A retrospective cohort study was performed within a veteran population with SCI at a US Department of Veteran Affairs hospital to determine the prevalence of limb loss. We hypothesized that premorbid SCI increased the likelihood of LE amputation.

Results: Of 1055 charts reviewed, 91 (8.7%) patients had an amputation, 70 (76.1%) had a dysvascular etiology. Transfemoral amputations were the most common level (n = 53) of amputation. Our results showed a positive correlation between the completeness of injury and the prevalence of amputation.

Conclusion: There is an increased frequency of amputation among the veteran population with SCI compared with that of the general US population. Amputations frequently occur at more proximal levels with motor complete injuries. Studies using a larger population and multiple centers are needed to confirm this alarming trend.
