X-ray of proximal fractures of the fifth metatarsal
Author:
Mikael Häggström [notes 1]
Proximal fractures of the fifth metatarsal are common,[1] and are distinguished by their locations:
- A proximal diaphysis fracture is typically a stress fracture, commonly among athletes.[2][3]
- A metaphysis fracture is also called a Jones fracture. Due to poor blood supply in this area, such a fracture sometimes does not heal and surgery is required.[4]
- A tuberosity fracture is also called a pseudo-Jones fracture or a dancer's fracture.[5] It is typically an avulsion fracture.[6]
Normal anatomy that may simulate a fracture include mainly:
- The "apophysis", which is the secondary ossification center of the bone, and is normal at 10 - 16 years of age.[7]
- Os vesalianum, an accessory bone which is present in between 0.1 - 1% of the population.[8]
