This paper investigated the recent trends in the incidence of distal radius and proximal humerus fractures in Tottori Prefecture.
Between 1992 and 1995, a survey was conducted on all distal radius and proximal humerus fractures treated at all hospitals and clinics in Tottori Prefecture. Among patients 35 years old and above, the survey found 1015 distal radius and 307 proximal humerus fractures during the observation period. The mean age-and gender-specific incidences were compared by chi-square test with data collected between 1986 and 1988 when we performed the same survey in Tottori Prefecture. The incidence of distal radius fractures in women increased significantly between 1986 to 1988 and 1992 to 1995 (P<0.01), while that of proximal humerus fractures increased significantly in both genders (P<0.01).
