Aim: To assess age and sex variation in the distal radius morphology in normal Indian population presents to secondary care centre.
Material and method: A cross-sectional prospective study was conducted in the Department of Orthopedics, SDH, Bagaha, West Champaran, Bihar, India, Total 160 healthy individuals were included in this study. We investigated the radiological distal radius index changes between four age groups. The study population included 160 normal subjects who were equally divided into four age groups (below 10 years, 10-20 years, 20-50 years, and above 50) of 20 males and 20 females according to age and sex. Radial inclination (RI), radial length (RL), palmar tilt (PT), and ulnar variance (UV) were measured in millimeters by the investigators. The measurements were performed with an orthopedic goniometer and a ruler.
Results: The average RI, PT, and RL was 24.11o, 11.88o , and 11.22 mm, respectively. Also, the average UV was +1.22 in the two above 20-year-old age groups. There was not any significant difference between the age groups except for UV. The UV in the two groups below-20-years-old was significantly different from the two groups above-20-years-old. But, no significant difference was observed between the two groups below-20, as well as between the groups above 20 regarding UV variation. No significant difference was detected between the males and females in any of the age groups regarding the mean variables. Although the mean UV in males and females belonging to the group 10-20-year-olds was -2.41 and -0.79, respectively, and the difference was not statistically significant.
Conclusion: There is significant ulnar variance change toward less negative ulnar variance with aging until maturity.
