![]() The most common 5th metatarsal fracture is a spiral oblique fracture of the mid-shaft of the metatarsal. The 5th metatarsal is unique in that it alone displays a number of fracture patterns not seen in the lesser metatarsals (2-4). The most common metatarsal fracture in a Lisfranc's dislocation would be a fracture of the second metatarsal base. This abrupt force resulted in fracture patterns that would partially or completely dislocate the metatarsal bases from the cuneiform bones. Martin (1790 -1864) was a 19th-century French surgeon in Napoleon's army who studied fracture patterns found when a person fell from a horse and was drug by the horse with their foot still in the stirrup. Lisfranc’s fractures are fractures of the metatarsal bases. Examples of crush injuries that result in metatarsal fractures include auto accidents or dropping heavy loads on the forefoot. Crush injuries have no reliable pattern of metatarsal fracture and result in individually unique fractures. Examples include an unseen hole in the ground or a foot that is caught under a pallet at work.Ĭrush injuries of the forefoot often result in traumatic fractures of the metatarsals. Traumatic metatarsal fractures of the central three metatarsals occur as the result of a fall where the foot is caught in a fixed position as the central mass of the body changes direction. Also, the fifth metatarsal shows fracture patterns that are unique to that one specific bone. As a result, it is not unusual to see several fractures of the central three metatarsals at the same time. Stress fractures of the 1st metatarsal are rare.Įach of the metatarsal bones are very strong when load is applied evenly to the metatarsals, but when load is applied in an abrupt or atypical manner, the bone is unable to sustain the load and fractures (breaks.) The central three metatarsals tend to accept load as a group, while the 5th metatarsal often acts independently of the central 3 metatarsals. ![]() The term march fracture dates back to 1855 and comes from Prussian military exercises that included long, sustained periods of marching.(1) The second and third metatarsals are most prone to fracture.(2) Stress fractures are less common in the 4th and 5th metatarsals. Metatarsal stress fractures are also known as march fractures.
