Background
Lower back pain is a commonly encountered complaint seen by the physicians. There are a variety of different radiographic views of the lumbar spine that can be obtained. An understanding of patient positioning and relevant osseous anatomy for each view is critical for accurate radiographic assessment and correct diagnosis of these patients.

Educational Goals / Teaching Points
This exhibit will: - Discuss common views used in lumbar spine radiology. - Describe patient positioning for each view and emphasize positioning pitfalls. - Review the radiographic anatomy associated with the lumbar spine. - Describe and illustrate lumbar spine anatomical variants and common pathology which can be highlighted with specific radiographic views.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will review lumbar spine anatomy, physiology and radiographic techniques. We will discuss each of the following views of the lumbar spine with patient positioning, normal anatomy and pathology: AP / AP, Lateral, Oblique(RPO, LPO), Lateral Flexion/Extension, AP side bending, lumbosacral junction (L5-S1 spot)

Conclusion
Correct diagnosis and treatment of lumbar spine pathology is important. Awareness of patient positioning and specific advantages associated with different lumbar spine views will help the radiologist to tailor an effective imaging approach. Familiarity with the imaging findings seen on each view may allow timely diagnosis and implementation of appropriate treatment strategies.
