Background:
Baumann's angle and Lateral capitellohumeral angle measurements are essential to check the degree of reduction in supracondylar fracture of humerus in children. Although the normal values of the angles are available for other populations, there is lack of study in our population for these angles. The objective of the study was to find normal values of these angles in in Nepalese children and to compare the findings with studies done elsewhere.
Methods:
The study is a prospective observational study.conducted at Department of Orthopedics and Trauma Surgery, Tribhuvan University Teaching Hospital. The study was conducted from July 2019 to June 2020. A total of 56 participants were included. Baumann's angle and Lateral Capitellohumeral Angle were measured on Xrays.
Results:
The mean(+/-SD) Lateral Capitellohumeral angle in our study was 48.4°(±3.40) The mean(+/-SD) Baumann's angle was 71° (±3.20). There was no significant difference in Lateral Capitellohumeral angle and Baumann's angle between different genders, age groups and right or left elbow.
Conclusions:
The measurements for elbow Baumann's and Lateral Capitellohumeral angles in our study were similar to other studies.
