However, specifically with regard to risk factors relating to occurrences of SSI after fixation of lower-limb fractures through IMN, information is scarce, given that the majority of the studies that analyzed the incidence of this complication did not allow for analysis of the risk factors relating to their occurrence. Until 2015, only Gaebler et al. had published results from an analysis on these risk factors. They concluded from their retrospective study that the risk of acquiring SSI after implantation of IMNs was 22.4 times higher among patients with Gustilo III open fractures than among patients with other types of fractures. However, these authors did not evaluate the importance of other factors that are considered to be associated with occurrences of SSI after fracture fixation.
