    Lumbar spine x-rays in the emergency department are most useful when patients present with an abnormal physical exam, tenderness, multiple positive findings, or contusions/abrasions. These clinical markers help optimize imaging use.

    Area of Science:

    • Emergency Medicine
    • Radiology
    • Clinical Decision Support

    Background:

    • Lumbar spine x-rays are frequently ordered in emergency departments.
    • Optimizing the use of diagnostic imaging is crucial for efficient patient care and resource allocation.

    Purpose of the Study:

    • To evaluate the diagnostic utility of lumbar spine x-ray series in emergency department settings.
    • To establish clinical criteria for the appropriate application of lumbar spine radiography.

    Main Methods:

    • Retrospective study of 552 consecutive emergency department patients who underwent lumbar spine x-rays.
    • Patients categorized into traumatic and nontraumatic groups, and by radiological findings (negative, possibly significant, positive).
    • Comparison of clinical findings between patients with positive radiological results and others.

    Main Results:

    • A significant correlation was found between positive lumbar spine x-ray findings and specific clinical indicators.
    • Abnormal physical examination (90% vs 61.5%), tenderness (72.5% vs 41.2%), multiple positive findings (42.5% vs 20.7%), and contusion/abrasion (15% vs 2.7%) were significantly associated with positive radiological outcomes.
    • These clinical findings can help differentiate patients likely to have significant radiological results.

    Conclusions:

    • Specific clinical findings, including abnormal physical examination, tenderness, multiple positive findings, and skin contusions/abrasions, are valuable predictors of positive lumbar spine x-ray results in the emergency department.
    • These criteria can guide the judicious use of lumbar spine radiography, improving diagnostic efficiency.
