Value of quantitative assessment using Multidetector CT in predicting ligamentous and meniscal injuries in acute tibial plateau fractures

Abstract

Purpose: To assess the ability of MDCT to predict ligamentous and meniscal injuries in acute tibial plateau fractures compared to MR images. Patients and methods: Forty patients with acute tibial plateau fracture and 15 control subjects were subjected to MDCT and MR images. Lateral plateau depression (LPD) and lateral plateau widening (LPW) were measured in coronal MDCT images. Meniscal, cruciate, and collateral ligaments injuries were evaluated in MR images. Results: Soft tissue injuries incidence was not related to Schatzker type (P > 0.05). LBD and LBW were different significantly between patients and control subjects ((P value 0.05). LPD > 6 mm or LPW > 7 mm increased possibility of Soft tissue injuries. Multiple soft tissue injuries were not related to Schatzker types (P > 0.05). LPD and LPW were correlated with number of soft tissue injuries. Conclusion: MDCT measurements of LPD and LPW are correlated with incidence and number of ligamentous and meniscal injuries. MDCT can predict ligamentous and meniscal injuries without waiting for MRI in acute tibial plateau fractures.
