Aggressive soft tissue infections and amputation in military trauma patients

Due to the nature of IED injuries, during the conflicts in Iraq and Afghanistan The traditional, two-stage amputation for unsalvageable combat lower limb injuries has evolved into a strategy of serial debridement and greater use of plastic surgical techniques in order to preserve residual limb length. This study aimed to characterise the current treatment of lower limb loss with particular focus on the impact of specific wound infections. The UK military trauma registry and clinical notes were reviewed for details of all lower limb amputation identifying: 51 patients with 70 lower limb amputations. The mean number of debridements per stump prior to closure was 4.1 (95% CI 3.5-4.7). A final more proximal amputation level was required in 21 stumps (30%). Recovery of A. hydrophillia from wounds was significantly associated with a requirement for a more proximal amputation level (p=0.0038) and greater number of debridements (p=0.0474) when compared to residual limb wounds withoutA. hydrophillia.
