What is the appropriate patient positioning angle for lumbar obliques?

• A. 30° off the bucky
• B. 45° off the bucky
• C. 60° off the bucky
• D. 90° off the bucky

Answer: (B)

The appropriate patient positioning angle for lumbar oblique radiographs is 45° off the bucky. This angle allows for the proper visualization of the lumbar vertebrae by projecting the vertebrae in an oblique view, essential for assessing certain anatomical structures and potential pathologies. At 45 degrees, the patient is positioned correctly to obtain images that showcase the lumbar spine's facet joints and other pertinent structures without significant overlap. This positioning technique ensures optimal image quality and diagnostic usefulness, as it provides a clear view of the lumbar vertebrae and their surrounding soft tissue. Angles lower than 45 degrees may not sufficiently demonstrate the anatomy, while angles higher than 45 degrees can create excessive distortion and shadowing of the relevant structures, making interpretation challenging. Hence, for effective evaluation and accurate diagnosis, maintaining a 45° angle is crucial.
