My kid was so kind and helped me create this presentation to

show how to measure a hip joint

We start by finding the point that the Perichondrium meets the Periosteum of the Illiac bone.

Now we draw a line along the Periosteum that will be our

baseline.

The next step is to draw a line from the tip of the bony Acetabular roof to the

Promontory of the bony Acetabular rim .

The angle between the lines is the Alfa angle

Then we draw a line from the Labrum to the proximal descent

point of the bony roof.

The angle between the lines is the beta angle

O.K my friends, now we know how to perform the 2 angle

measurements. This technique is very easy to be done and should

be used in all casesall cases.
