Many conditions including trauma can affect the range of motion and carrying angle of the elbow in children. The method employed was cross-sectional clinical measurement of 600 elbows (300 patients) range of motion and carrying angle in normal children. We found significant increases in range of motion and carrying angle with age (P<0.01) and significantly increased range of motion and carrying angle in females as compared with males (P<0.01). In conclusion, elbow joint range of motion and carrying angle increase with age. This is the first cross-sectional analysis of range of motion and carrying angle to our knowledge in the pediatric population. Increased elbow extension may contribute to the increased carrying angle seen in females compared with males.
Background-Childhood overweight has become a serious health problem among children and adolescents in the United States. No previous study, to our knowledge, has analyzed the effect of body mass index (BMI) on range of motion and carrying angle of the elbow joint in a healthy pediatric population. The primary objective of this study was to determine the effect of BMI on orthopedic parameters of the elbow joint, including range of motion, flexion, extension, and carrying angle.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
