Three x-ray exposures are required during a long bone measurement study. The first exposure is taken with the limb in a neutral position, the second exposure is taken with the limb rotated externally, and the third exposure is taken with the limb rotated internally. These images are used to calculate the bone lengths and angles needed for diagnosis and treatment planning.
