摘要

Objectives

Bone age calculation remains a surrogate marker of the growth remaining. This can affect the decision for management of angular deformities in children. The purpose of this study was to evaluate the difference in growth remaining using chronological age and bone age.

Methods

A total of 51 patients were enrolled, boys of age group 12–16 years and girls of age 10–14 years. The remaining growth was calculated using the chronological age, Sauvegrain’s method.

Results

Mean chronological age was 12.8 years (10–16), and mean Sauvegrain’s method age was 13 years (11.5–15). Mean growth remaining using chronological age and Sauvegrain’s method was 22.8 ± 13.4 months, 4 ± 5.4 months, respectively. The mean difference between growth remaining between chronological age and Sauvegrain’s method was 18.7 months (p < 0.001). The difference between growth remaining using the above two methods decreases statistically significantly as the age advances.

Conclusions

Significant differences are there in growth remaining using chronological age and bone age. Consideration of growth remaining using bone age is strongly recommended in pubertal angular deformity surgeries to reduce the risk of overcorrection and treatment failures.
