A clinical and statistical study of football injuries at an overseas air force base recorded 290 injuries. Of these, 111 were major football injuries. The knee was the most frequently injured area, and sprains were the most frequent type of disabling injury. Thirty-eight players were hospitalized, 22 players were operated upon, and 65 players received injuries such that they were unable to finish out the season. There were no deaths. The number of players competing was 465. There were 34 games among five teams during the 20-game 1965 season and the first 14 games of the 1966 season. The classification of these injuries and their grading by degree of severity is accomplished through the use of theAMA's Standard Nomenclature of Athletic Injuries.
