Foot

What It Is

The fifth metatarsal is the long bone along the outside of your foot (American Academy of Orthopaedic Surgeons, n.d.a). It can break suddenly in an injury, or develop a stress fracture over time.

Regular fractures of the fifth metatarsal (sometimes known as the 5th met) can be caused by a direct blow to the foot or by a twisting injury (American Academy of Orthopaedic Surgeons, n.d.a). The most common type is a break at the base of the bone, where the ligament attached there pulls a small piece of bone away. This is called an avulsion fracture. It usually happens when the foot and ankle are twisted downward and inward (American Academy of Orthopaedic Surgeons, n.d.a), much like rolling your ankle in an ankle sprain, for example when turning sharply while running or tripping over an object.

Stress fractures are small cracks in the bone, and these can also occur in the 5th met. Most are caused by overuse and repetitive activity, and they are common in runners and in athletes who play running-intensive sports such as football and basketball. The most common cause is a sudden increase in physical activity (American Academy of Orthopaedic Surgeons, n.d.b). To recover from a stress fracture, rest is crucial.

The pain from a stress fracture usually develops gradually and gets worse with weight-bearing activity. With the fifth metatarsal, it is felt along the outside part of your foot (American Academy of Orthopaedic Surgeons, n.d.b).

How much weight you can put through the foot depends on where the break is, so follow the advice of the doctor treating you. For the common avulsion fracture at the base of the bone, UK hospital advice is that you may walk on the foot as much as the pain allows. The pain, tenderness and swelling usually settle over 3 to 5 weeks, although it can take up to 12 weeks for symptoms to settle completely (Northern Care Alliance NHS Foundation Trust, 2025). A Jones fracture usually needs a period with no weight on the foot (see below).

Fifth Metatarsal Fracture Anatomy

There are five metatarsals in each foot. They are the longer bones in the foot that join the toes to the rest of the foot. The 5th met is the outer of the 5 metatarsals.

A Jones fracture is a break across the base of the fifth metatarsal, in a particular area where the wider end of the bone meets its shaft (American Academy of Orthopaedic Surgeons, n.d.a; Caruso and Chin, 2025). The name is sometimes wrongly used for all fractures near the base of the bone (Caruso and Chin, 2025). This area has a poor blood supply, so Jones fractures may take longer to heal, sometimes do not heal at all (called nonunion), and are more likely to need surgery (American Academy of Orthopaedic Surgeons, n.d.a).
