This condition is a fracture of the foot’s fifth metatarsal, the bone that attaches to the base of the small toe. A Jones fracture refers only to a fracture that occurs at the proximal end of this bone, the end closest to the ankle. Most Jones fractures are caused by overuse, repetitive stress, or trauma. They can also be caused by rolling the ankle inward, or inversion injuries of the ankle. They can develop gradually or occur suddenly and are often mistaken for an ankle sprain.
Symptoms include pain at the middle and outer side of the foot, swelling, bruising and difficulty walking.
A Jones fracture is typically treated by immobilizing the leg in a short leg cast. Surgery may be a treatment of choice for some athletes or other active people, or in cases where the fracture fails to heal itself.
