[Advice on the x-ray positioning of the upper and the lower leg].
Roentgenographic images of the femur and tibia to demonstrate the bones in two true right-angled projections (anteroposterior, lateral view) can be obtained by using a small hydrostatic level with two levels positioned at right angles against each other. By taping the small plastic device to the skin of the leg under examination, rotation of the limb between the two x-ray exposures can be controlled and adjusted to exactly 90 degrees. Compared to other common positioning procedures (rotation of the leg to approximately 90 degrees by the patient; angulation of the x-ray tube to 90 degrees around the leg) this method yields the highest accuracy of adjustment.
