A survey of hospital records at two mental institutions permitted analysis of the sex, race, and age incidence of patients with hip fractures during a period of three years and two months. Fractures due to minimum trauma occurred more frequently among the white population and among confined institutional patients than among a previously studied non-hospitalized population. Environmental factors, particularly physical activity, seem to be important in senile osteoporosis.
