Normal Age-Related Alterations on Distal Radius Radiography

  Background: The present study was designed to ascertain serial changes on distal radius radiographic parameters attributable to aging.       Methods: In this prospective study, the sample consisted of ۱۲۰ healthy individuals who were divided into four age groups each containing ۱۵ males and ۱۵ females. In the two below-۲۰-year-old groups, only ulnar variance could be investigated. Wrist radiography was taken and then parameters of the distal radius were measured and compared based on age and sex.       Results: Average UV was -۲.۴۸ mm and -۱.۶ mm in the ۲-۹ and ۱۰-۱۹-year-old age groups, respectively. Also, in the two above-۲۰-year-old groups, the average radial inclination (RI), palmar tilt (PT), radial length (RL), and UV was ۲۳.۷º, ۱۲.۴º, ۱۰.۵ and +۱.۱ mm, respectively. Considering ulnar variance, no significant difference was found between the ۲-۹- and ۱۰-۱۹-year-old groups, as well as among the two above-۲۰-year-old groups. However, a significant difference was observed between the below ۲۰ and above ۲۰ groups. The study results showed no significant differences between males and females in any of the study groups.       Discussion: There is significant ulnar variance change toward less negative ulnar variance with aging until maturity.
