The incidence of the hip fracture was investigated more than 40 years after exposure to A-Bomb when victims were for the most part aged above 60 years. The numbers of hip fractures in Nagasaki City were 238 in 1989 and 235 in 1990 and 102 and 113 (about 46%) of them had heed exposed to A-Bomb. The incidence of such fractures per 100, 000 in 1989 and 1990 were 280.1 and 307.4, respectively in the exposure group and 316 and 285.6 in the non-exposure group.There was no significant difference between the exposure and non-exposure groups.When the significant of difference was assessed by the survival-rate analysing method, no significant difference was noted between persons exposed and unexposed to A-Bomb and between victims exposed near the center of explosion and at more distant places. Taken altogether, exposure to A-Bomb is considered to produce no influence on the incidence of the hip frature.
