A<unk>  is a break in a specific part of the fifth metatarsal of the foot between the base and middle part known for its high rate of delayed healing or nonunion. It results in pain near the midportion of the foot on the outside. There may also be bruising and difficulty walking. Onset is generally sudden. The fracture typically occurs when the toes are pointed and the foot bends inwards. This movement may occur when changing direction while the heel is off the ground such in dancing, tennis, or basketball. Diagnosis is generally suspected based on symptoms and confirmed with X-rays. Initial treatment is typically in a cast, without any walking on it, for at least six weeks. If, after this period of time, healing has not occurred, a further six weeks of casting may be recommended. Due to poor blood supply in this area, the break sometimes does not heal and surgery is required. In athletes, or if the pieces of bone are separated, surgery may be considered sooner. The fracture was first described in 1902 by orthopedic surgeon Robert<unk> , who sustained the injury while dancing.
