8.2.8.1. Hip Joint Measurement
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 BL (Baseline) connects the osseous acetabular convexity to the point where the joint
capsule and the perichondrium unite with the iliac bone;
 Line IL(Inclination Line) connects the osseous acetabular convexity to the labrum acetabulare;
 Line RL(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.
To use Hip Joint Angle measurement:
1. Invoke the B-mode application measurement function.
2. Select HIP-> HIP Angle on the touch screen and then select Left or Right on the touch screen.
3. Press the Tool paddle key to select the 3 Distances or Semi-auto Method.
3 Distances method:
Add the baseline, roof line, and inclination line by the method of measuring distance with two
points, and the system displays the results of α and β angle.
Semi-auto method:
a. Move this horizontal straight line to place the baseline. Rotate the Angle knob on the console
to adjust the angle of baseline if necessary.
b. Press <Set> key and the default angle α and roof line comes out.
c. Use the trackball to place the roof line and rotate the Angle knob to adjust the angle α.
