OBJECTIVE: The aim of our study was to clarify the ligamentous anatomy of the Lisfranc joint complex and show the diagnostic capability of MRI in the assessment of the Lisfranc joint complex with detailed anatomic correlation in cadavers. MATERIALS AND METHODS: Ten fresh cadaveric feet were studied with high-spatial-resolution MRI before and after the intraarticular injection of a gadopentetate dimeglumine solution. MR images were evaluated by two readers in consensus, with emphasis on the visibility of the ligamentous structures and their appearance. Readers also measured the dimensions (length, width, and thickness) of the Lisfranc ligament and of the first plantar tarsometatarsal ligament, or plantar Lisfranc ligament. For anatomic analysis, nine cadaveric specimens were sectioned in 3-mm-thick slices in the same planes used during MRI. One additional foot specimen was used for dissection. RESULTS: In all 10 cadaveric specimens we were able to identify and characterize with MRI the different ligamentous elements that contribute to the overall stability of the Lisfranc joint complex. CONCLUSION: By clearly defining the normal ligaments that contribute to the stability of the Lisfranc joint, MRI allows a more precise and correct diagnosis of the origin of the Lisfranc joint instability, perhaps permitting a more specific surgical management. MRI also allows a better understanding of the normal imaging anatomy of the different ligamentous components of the Lisfranc joint, mainly of the Lisfranc and plantar Lisfranc ligaments. |
