IntroductionProvisional reduction plating has been advocated as a reduction aid for tibial shaft fractures. Concerns regarding soft tissue stripping, infection, wound complications and nonunion have been postulated. Recent studies investigating reduction plating present patient cohorts where plates are removed or left to the discretion of the surgeon. This study aims to identify a cohort of open tibial shaft fractures treated with intramedullary nailing aided by permanent reduction plating. Our hypothesis is that permanent reduction plating in conjunction with intramedullary nailing of open tibia fractures does not increase risk of nonunion, infection or time to fracture union compared to intramedullary nailing alone.MethodsAn IRB approved retrospective study was performed using trauma registry data from January 2014 to June 2018 at a Level 1 trauma center. Open AO/OTA 41A/42 A-C/43A tibial shaft fractures treated with intramedullary nail alone (IM) or intramedullary nail and permanent reduction plates (PP) were included in patients over 18 years of age with at least six month follow up or until fracture union. Patient demographics, fracture characteristics, mechanism of injury, medical comorbidities, and length of follow up were recorded along with time to union, incidence of nonunion and treatment for documented or suspected infections.ResultsDuring the study period, 389 patients underwent tibial intramedullary nailing with 162 identified as open fractures. 91 patients met inclusion criteria with 39 in the PP group and 52 in IM group. Statistical analysis revealed no difference between the two groups except more AO/OTA 42A fractures were noted in the IM group. Average follow up was 8.0 and 10.2 months for PP and IM respectively. Nonunion occurred in 2 PP group patients and 7 in the IM group (p = 0.29). Time to union was 5.5 months for PP group and 6.1 months for IM group (p = 0.39) with 4 infections in the PP group and 10 infections in IM group (p = 0.38).ConclusionDespite the small sample size, this study suggests that permanent reduction plating, in the setting of open tibia fractures, does not delay time to fracture union or increase risk of nonunion or infection.Copyright © 2021.
