    Area of Science:

    • Orthopedics
    • Radiology
    • Neurosurgery

    Background:

    • Lumbar disc herniations often present with musculoskeletal findings, including protective listing or reduced lateral mobility.
    • This protective posture aims to minimize pressure on the affected nerve root by splinting the disc.

    Purpose of the Study:

    • To investigate if maximal lateral bending (dynamic) X-rays can delineate the relationship between lumbar disc herniation and nerve roots.

    Main Methods:

    • Three hundred patients considered for routine lumbar spine X-rays underwent lateral bending (dynamic) films instead.
    • Results were correlated with myelograms and/or surgical findings when available.

    Main Results:

    • Lateral bending roentgenograms demonstrated the ability to frequently pinpoint the specific level of lumbar disc herniation.

    Conclusions:

    • Dynamic lateral bending X-rays are a valuable tool for localizing lumbar disc herniations.
    • This method offers a potentially more precise diagnostic approach compared to static imaging alone.
