“…There are many studies that showed definite a correlation between ulnar length and height and gender of the individual. 7 27 28 We have also correlated the ulna length with height of children and data showed that ulna length and height ratio falls between 0.10–0.20 in ~97% children. Therefore ratio between 0.10–0.20, is within the normal range for pediatric age group and we termed this as Indian ratio.…”

Objective The aim of this study is to create clinical normative data for ulnar length in the pediatric population and to demonstrate the usefulness of such data. Materials and Methods A nationally representative sample of healthy children aged 1 day to 18 years from five centers across India was collected. The percutaneous length of the ulna was measured by using a certified calibrated measuring tape across all centers. Other variables such as geographical domicile, dominance of the hand, age, body mass index (BMI), and sex of the child were also recorded. Results In total, 1,300 children (883 males and 417 females) with age ranging from 1 day to 18 years were included in the study. Gradual lengthening of the ulna was seen in both male and female children with increasing age without a significant difference; however, at 8, 9, and 14 years, there was significant lengthening of the ulna in males compared with females although the difference was statistically insignificant at 17 years. Apropos BMI at 16 years of age, a longer ulna was observed in obese children. Later on, at 18 years, the difference in ulnar length was insignificant. South Indian children had a significantly longer ulna up to the age of 11 years, but after the age of 11 years there was no difference in ulnar length in all zones. The length of the ulna was not affected by hand dominance. There was good inter-observer agreement and reliability between different centres. Age, zone, and gender, had statistically significant effect on the length of ulna but BMI and hand dominance was not significant. Conclusion This multicentric study provides normative data on the percutaneous length of the ulna in the Indian pediatric population. Gradual lengthening of the ulna was seen in all children with increasing age. The length of the ulna was significantly more in male, obese, and in South Indian children. However, except for age, other factors become insignificant at maturity.
