Jones (5th Metatarsal) Fracture
What is a Jones fracture?
A Jones fracture is a fracture at the base of the 5th metatarsal. 5th metatarsal base fractures are divided into two fracture types. Avulsion fractures occur when a tendon insertion pulls off a piece of bone, typically during an injury such as a rolling the ankle. These fractures tend to heal well with conservative management. Jones fractures occur in a region of bone with a poor blood supply, and as a result can take longer to heal. These fractures can occur from overuse (stress fracture) or from a trauma with a sudden break. Other fractures of the 5th metatarsal such as shaft and metatarsal head and neck fractures may also occur.

How is a Jones fracture diagnosed?
A Jones fracture is diagnosed by taking a history of the injury and performing a thorough physical examination. X-rays and other imaging studies may be necessary.
How is a Jones fracture treated?
A Jones fracture is initially treated with rest, ice, immobilization in a cast or walking boot, and NSAIDS (anti-inflammatory medication). Crutches and a period of non-weight bearing may also be recommended.
Surgery may be necessary if the bone fails to heal. This can include placing a screw to stabilize the bone to allow it to properly heal. Bone grafting of the fracture may be performed as well.
