Pauwel's angle

Pauwel's angle is the angle between the line of a fracture of the neck of the femur and the horizontal as seen on an anterio-posterior radiograph.[1] Pauwel's angle is named after the German orthopedist Friedrich Pauwels.[2]

Clinical Use

An increasing angle leads to a more unstable fracture and an increase in the shear stress at the fracture site. This shear leads to higher rates of nonunion.

Pauwel's Classification

II >30°/<50°
