Nelaton’s line:
Let the patient lie in supine position with the hip flexed to the angle of between 45° and 60°, draw a line from the anterior superior iliac spine to ischial tuberosity. Normally, the line passes through the top of greater tuberosity. If the top is superior or inferior to the line, it indicates a pathological change.

Bryant triangle:
Let the patient lie in supine position. Draw a perpendicular line from the anterior superior iliac spine to the surface of the bed, a horizontal line from the top of greater tuberosity to the perpendicular line and another line from the anterior superior iliac spine to the top of greater tuberosity, forming a right-angled triangle. Comparing the length of base in two triangles of both sides, if it is shorter in one side, it is indicated that the greater tuberosity of the side has displaced upward.
