Jones' fracture.

The Jones' fracture is defined as a transverse fracture of the proximal fifth metatarsal diaphysis within 1.5 cm of the tuberosity. It is classified radiographically as acute, delayed union and nonunion. Some orthopedists also have added a classification of stress fractures. The best form of treatment is based on the presence or absence of medullary sclerosis adjacent to the fracture site. In addition, the prescribed treatment must be adhered to by the patient to prevent increased morbidity associated with this fracture.
