![]() Stress fractures at the base of the first or second metatarsals (or rately other metatarsal bones) are less common. Among stress fractures of the metatarsal bones, the middle and the distal portions of the corpus ossis metatarsalis II or III are most common. ![]() Injury to the metatarsals is common in both acute and chronic settings and they are the most common site of stress fractures in the human skeleton. The next most common fracture finding was a specific combination of second, third and fourth metatarsal fractures. Children under the age of 5 years are more likely to have first metatarsal fractures, with a frequency of isolated first metatarsal fractures of 51%, in contrast to those more than 5 years old, who are more likely to have fifth metatarsal fractures, depending on the age group, a frequency as high as 65%. The highest rate of fracture in childhood involves the fifth metatarsal, followed by the third metatarsal. Metatarsal fractures are common in the pediatric population, accounting for close to 60% of all pediatric foot fractures. ![]() The distribution of the fractures looks as follow (figure 1) :įigure 1: distribution of metatarsal fractures according to their location. They are equally amoung men and women and among all racial groups. They are about ten times as frequent as Lisfranc-dislocations. It are the most common injuries of the foot. Įpidemiology/ Etiology ĥ to 6% of all fractures treated in primary care are metatarsal fractures. Lateral is the ligament system with fibers between C2 and M2, just as crossed fibers between C3-M2 and C2-M3. The strong dorsal ligament of lisfranc between the lateral side of C1 and the medial side of M2. The basis of the os metatarsale 2 is surrounded the three ossae cuneïforme with strong ligaments. The tarsometatarsal joints have relatively flat articular surfaces and strong, short ligaments who admit small translations and tilting movements. The tarsometatarsal joint is also called the line of Lisfranc. At the distal side they articulate with the basis of the proximal phalanges. They form joints with at the proximal side: ossa cuneiformia and at the medial and lateral side the os cuboideum. ![]() Every metatarsal bone consists out of three parts: caput ossis metatarsi, corpus ossis metarisi and the basis ossis metatarsi. The foot consists out of 5 metatarsal bones per foot. These long thin bones are located between the toes and the ankle (between the tarsal bones in the hindfoot and the phalanges in the forefoot).
