This document provides guidelines for analyzing various spinal x-rays, including cervical, lumbar, and lateral views. Key points analyzed on x-rays include stress lines, vertebral angles and positions, pelvic tilt, and spinal curvatures. Deviations from normal values are measured in degrees or millimeters and can indicate loss of motion, ligament instability, or subluxations. The document establishes a standardized method for interpreting spinal x-rays and identifying areas of dysfunction.
