Baumanns Angle
Other Names
- Baumann's Angle
- Baumann angle
- Humeral-capitellar angle
- Humerocapitallar Angle
Introduction
- Used to evaluate the displacement of pediatric supracondylar fractures of the humerus
- Measured on a frontal radiograph with the elbow in extension
Interpretation
- Angle: formed by the humeral axis and a straight line through the epiphyseal plate of the capitulum
- 64 - 81º is considered normal1[2]
- Baumann’s angle is better evaluated by comparison to the contralateral side
- Difference of more than 5° between the two sides is considered abnormal
- Increased Bauman's angle will occur with residual varus and internal rotation deformities.
