Abstract

Abstract : Background: Soft-tissue complications often dictate the success of limb salvage and the overall outcome of open fractures. Based on prior work at the R Adams Cowley Shock Trauma Center, the authors hypothesize that wounds larger than 200 cm 2 are associated with a greater likelihood of both flap-related reoperation and wound complications among patients requiring soft-tissue reconstruction with a rotational flap or free tissue transfer. Methods: This study was a secondary analysis of Fluid Lavage in Open Wounds trial data that included all patients who received a rotational or free tissue flap transfer for an open fracture. The primary outcome was flap-related reoperation within 12 months of injury. The secondary outcome was wound complication, which included events treated operatively or nonoperatively. Multivariable logistic regression was used to assess the association between wound size and outcomes, adjusting for confounders. Results: Seventeen percent of the 112 patients required a flap-related reoperation. A wound size greater than 200 cm 2 was not associated with reoperation in an unadjusted model ( p = 0.64) or adjusting for Gustilo type ( p = 0.70). The sample had an overall wound complication rate of 47.3 percent. Patients with a wound size of greater than 200 cm 2 were three times more likely to experience wound complications (OR, 3.05; 95 percent CI, 1.08 to 8.62; p = 0.04) when adjusting for moderate to severe wound contamination and wound closure in the operating room. Conclusion: The findings of this study demonstrate that wound surface area is an integral determinant for wound complication following soft-tissue flap treatment, but found no association between wound surface area and flap-related reoperation rates.
