Abstract
Objective
The proximal fibula plays an important role in the knee joint; however, it has not been given enough attention by surgeons. This study aimed to investigate the risk factors for concomitant proximal fibular fractures in patients with tibial plateau fractures through computed tomography (CT) imaging.
Materials and Methods
From January 2016 to November 2017, patients who underwent percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures at a level 1 trauma centre institute were included in this retrospective study. Full materials of CT imaging were obtained for measurements. Schatzker’s and a newly proposed classification system were used for the fracture of the tibial plateau and proximal fibula, respectively. Several clinical and radiological characteristics were recorded, and the impact of those variables on fibular fractures was assessed with univariate and multivariate analyses.
Results
In total, 174 patients were enrolled in the study with mean age of 45.6±13.1 years. The incidence of combined proximal fibular fracture was 38.3%. Schatzker type VI fracture had the highest rate of fibular fracture (77.4%). High-energy-pattern tibial plateau fractures (p=0.029) and posterolateral joint facet (PJF) involvements (p=0.002) are risk factors for proximal fibular fracture on multivariate analysis. Neither posterolateral column (PLC) involvements nor fracture displacement correlated with proximal fibular fractures.
Conclusions
Proximal fibular fractures were commonly seen among patients who sustained tibial plateau fractures. Schatzker type VI fractures had the highest rate of fibular fractures than other fracture types. High-energy fractures and PJF involvements correlated with a higher risk of proximal fibular fractures. A better understanding and awareness of the risk factors for proximal fibular fractures will provide surgeons with comprehensive understanding of tibial plateau fractures.
