Normal characteristics of the Baumann (humerocapitellar) angle: an aid in assessment of supracondylar fractures

Abstract

We evaluated the normal Baumann (humerocapitellar) angle in 114 children aged 2-13 years because the angle has been proposed to be useful in assessing alignment of the elbow in children with supracondylar fractures of the humerus. In this age range, the angle did not change significantly, nor was there any significant difference between the angle in boys and girls. The mean Baumann angle was 72 degrees (SD 4 degrees), and 95% of normal elbows had a Baumann angle of 64 degrees-81 degrees.
