Suprapatellar intramedullary nail combined with screw fixation has comparable surgical outcomes to minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures

Purpose To compare union rate, union time, alignment, and complication rate in ipsilateral tibia plateau and shaft fractures treated via suprapatellar intramedullary nailing with screw fixation and minimally invasive locking plate fixation. Materials and methods A retrospective study was conducted on 48 patients who underwent minimally invasive plate fixation ( n = 35) or suprapatellar intramedullary nailing with screw fixation ( n = 13), for the treatment of ipsilateral tibial plateau and shaft fractures with at least 1-year follow-up. Union rate, union time, radiologic alignment, and complication rate such as malalignment, nonunion, and fracture-related infection (FRI) were investigated. Results Demographic data were not different between the two groups. Coronal plane alignment was 0.17 ± 4.23 in the plate group and −0.48 ± 4.17 in the intramedullary nail group ( p = 0.637). Sagittal plane alignment was −0.13 ± 5.20 in the plate group and −1.50 ± 4.01 in the suprapatellar intramedullary nail group ( p = 0.313). Coronal and sagittal malalignment recorded equal results: ( p > 0.99), FRI ( p = 0.602), nonunion and union times recorded ( p = 0.656) and ( p = 0.683, 0.829), respectively, and showed no significant difference between the two groups. Conclusion Suprapatellar intramedullary nailing with screw fixation had similar surgical outcomes with minimally invasive locking plate fixation in ipsilateral tibial plateau and shaft fractures in terms of union rate, union time, alignment, and complication rate. Thus, frequent use of intramedullary nailing combined with screw fixation is anticipated in patients with ipsilateral tibial plateau and shaft fractures when the soft tissue condition is not desirable.
