The Measurements and Standardization of Humerocondylar Angle in Children

Abstract

We found that HCA is close to the well-accepted figure of 40 degrees. Interestingly, this value remains the same in all age groups. That means that the geometry of the distal humerus in sagittal plane is established very early during the growth and remains constant. Due to significant individual variations of HCA, it alone cannot be sufficient for final decisions in evaluation and treatment of supracondylar fractures.
