AcRimIschL

Rim of the acetabulum at the intersection of the axis of the ischium―as defined by the linear buttress emanating from it in the direction of the Ischial tuberosity generally.

9

1

oRecFemRHL

Origin of the rectus femoris reflected head on groove just above acetabulum.

10

1

AIISL

Anterior inferior iliac spine, most caudal (i.e. furthest along the ilium from the sacrum) point.

11

1

ASISL

The most caudal point on the anterior superior iliac spine which, when observed perpendicularly to the iliac plane, has the greatest curvature.

12

3

oTFLL

Mid point of IL-TUB-GL and ASIS (origin of Tensor Fascia Latae.)

Iliac Tubercle, external. The point on the gluteal margin of thickest width of iliac crest cranial to ASIS.

14

1

IlTubInL

Iliac Tubercle, internal. The point on the interior surface on the crest of thickest width of iliac crest cranial to ASIS.

15
