Stress fracture of the cuneiform bones.

Stress fractures are relatively infrequent in average radiological practice. They occasionally occur in children and older women and in certain groups like ballet dancers and athletes, but among military recruits they are a fairly common injury. In 1966 Gilbert and Johnson reported an average of 375 cases per year at the Marine Corps Recruit Depot (San Diego, Calif., USA). In a training group of 1228 men and 102 women at the US military Academy 22 fractures were found in three months (Protzman and Griffis, 1977). At the Department of Radiology of the Central Military Hospital in Helsinki we have found, during the last five years, an average of 90 cases per year.
