[Post-traumatic necrotizing fasciitis].

We are reporting the case of a 39-year-old male, without notable previous history except for an important alcoholic and tobacco consumption, who suffered a bicycle accident resulting in a minor wound on the left elbow. The neglected wound evolved extremely rapidly towards a necrotizing fasciitis, which underwent further complications consisting of a heat shock and multivisceral failure that necessitated reanimation procedures. The patient benefited a triple antibiotic therapy (amoxicillin-clavulanic acid, ornidazole and levofloxacin) and an extensive surgical debridement. The progression was then slow but favourable. The patient is now in functional reeducation. This observation illustrates the rate of evolution of the lesions caused by necrotizing fasciitis and reminds on the importance of prompt therapy.
