– See: Midfoot/Forefoot Fractures – Discussion: – anatomy of the midfoot – mechanism: – because 2nd metatarsal is the longest metatarsal proximally, it will often be frxed at its base, with the other metatarsals dislocated; – dorsal capsule of Lisfranc’s joint, lacking sufficienct reenforcement, will to support the load and will collapse, resulting in dorsal … Read more
