• ABSTRACT
    • Most authors agree that anatomic reduction is the key to optimal results in treatment of injuries of the Lisfranc joint; a few controversies remain. One controversy is the identification of the strongest ligament of the second metatarsal-medial cuneiform articulation-the critical ligament of the Lisfranc joint. The purpose of this study is to objectively quantify the cross-sectional area of each ligament of this crucial joint. Twenty cadaveric feet were dissected to isolate the second metatarsal-medial cuneiform articulation. The point of maximum thickness, height, and width of the dorsal, plantar, and interosseous ligaments were measured using handheld calipers at the second metatarsal attachment. The distribution failed to pass Mauchly's test of sphericity, so the Greenhouse-Geisser method was used to assess differences in the height and width to a P
