Bryant's triangle

A surface marking of clinical importance is Bryant's triangle (or iliofemoral triangle), which is mapped out thus:
 * the hypotenuse of the right angled triangle is a line from the anterior superior iliac spine to the top of the greater trochanter.
 * its sides are formed respectively by:
 * a vertical line from the anterior superior iliac spine
 * a perpendicular line from the top of the greater trochanter.
