Hip Joint Angle Measurement:
Hip Joint Angle Measurement is intended to evaluate the development of acetabular roof and the
subluxation of femoral head for pediatrics. This measurement is performed by adding three straight
lines on the anatomic image, thereby calculating two angles. See the illustration below.
Line A (Baseline) connects the osseous acetabular convexity to the point where the joint capsule
and the perichondrium unite with the iliac bone;
Line B(Inclination Line) connects the osseous acetabular convexity to the labrum acetabulare;
Line C(Roof Line) connects the lower edge of the iliac bone to the osseous acetabular convexity.
α is the angle between baseline and roof line.
β is the angle between baseline and inclination line.
