Metatarsals - 5th, base (Jones fracture)

back to Foot overview

Glossary

General considerations

The first metatarsal takes 50% of the body weight with ambulation and so it is most important that anatomic reduction is correct after fractures have occurred. However, the second through 5th metatarsals each take 10-15% of body weight. The careful reconstruction of the 2nd – 5th metatarsals diminishes the chance for late malposition and metatarsalgia. The Jones fracture is the most common metatarsal fracture.
