PG - 433-441 LID - 10.1007/s00068-017-0797-3 [doi] AB - INTRODUCTION: The anatomy of the distal tibia accounts for reduced biomechanical stability and higher complication rates when treating distal tibiofibular fractures with an intramedullary tibia nail (IMTN). The goal of this study was to identify variables that affect the stability of IMTN. We assessed the value of additional fibular fixation, angular stable interlocking screws (ASLS) and multiplanar screw configuration in IMTN. PATIENTS AND METHODS: A retrospective cohort study was performed including 184 distal tibial fractures and associated fibula fracture treated with IMTN. Relevant demographic, fracture-related (type and level of the tibia and fibula fracture) and operative variables (depth of the nail, screw type and configuration, use of polar screws, fibular fixation) were studied. Coronal and sagittal alignment was assessed directly and 3-6 months after IMTN. Loss of reduction (LOR) was classified as 5-9 degrees or >/=10 degrees . RESULTS: 48.4% of the patients showed >/=5 degrees LOR in one or both planes. Coronal LOR 5 degrees -9 degrees significantly correlated with low tibial fractures (p = 0.034), AO/OTA type 43 distal tibial fractures (p = 0.049), and sagittal LOR 5 degrees -9 degrees (p = 0.015). Although sagittal LOR 5 degrees -9 degrees was associated with fibular fractures (non-fixated suprasyndesmotic, p = 0.011), conversely we could not demonstrate the added value of (suprasyndesmotic) fibula fixation in IMTN. Coronal LOR >/=10 degrees significantly correlated with AO/OTA type 43 distal tibial fractures (p = 0.009). In contrast to multiplanar configuration, we found a clear benefit of ASLS in distal IMTN locking. CONCLUSIONS: The level of the tibial fracture (AO/OTA type) and (suprasyndesmotic) fibular fractures were the main determinants of LOR after IMTN. ASLS was found to increase the stability of IMTN. Due to heterogeneity, however, we could not demonstrate the value of fibular fixation in IMTN. Therefore, a future prospective study with uniform treatment strategy for IMTN of distal tibiofibular fractures, with or without fixation of the fibula, is mandatory.
