Introduction: The purpose of this study is to establish the correlation of clinically measured carrying angle with four radiological angles, i.e., Humerus–Elbow–Wrist angle (HEWA), Humero-ulnar angle, Metaphyseal–Diaphyseal angle, and Baumann's angle, and to find out which of the above-mentioned angles co-relates best with the clinically measured carrying angle. Methods: We studied 100 patients in the age group of 2–12 years after Ethics committee approval and informed consent from parents. Clinical angle was measured using goniometer and radiological angles marked on antero-posterior elbow X-ray using a standard method. Collected data were studied using statistical tests to find out correlation. Results: Pearson correlation coefficient for humerus–elbow–wrist angle found to be 0.674 followed by Humero-Ulnar angle (r = 0.417). Regression coefficient for humerus–elbow–wrist angle is 0.635 (p value < 0.001). Conclusion: Humerus–Elbow–Wrist angle correlates better compared to other radiological angles in assessment of varus–valgus angulations of elbow & will not only play a vital role in pre- operative planning of deformity corrections but also in the evaluation & comparison of the post-operative functional outcomes.
