Routine X-rays Not Needed March 25, 2009

Following up on my previous post about the necessity of X-rays, I came across a review of the literature for low back imaging.

INVISIBLE_TEXT

In 1994, the AHPR began recommending against imaging of the low back in the early stages of acute low back pain. This study was undertaken to investigate the relationship between the use of immediate X-rays for the low back and the clinical outcome of the case.

479 articles were identified and reviewed. The authors found no differences in long term and short term outcomes between those who were X-rayed immediately and those who simply received treatment.

They concluded that for patients who present with simple uncomplicated low back pain (no red flags present), X-raying their back did not lead to any greater improvements. Since there is no benefit to imaging the back, but there are draw backs (radiation exposure, cost), routine imaging should be avoided.

Ultimately, every clinician has to rationalize their decisions when it comes to the assessment and treatment of their patients. I will often explain my decision not to X-ray with the fact that the X-ray result will not change my clinical management of their case. We know already from previous studies that many things are seen on X-ray and MRI that don’t have clinical relevance and may actually confuse the issue.

Should I Get An X-ray? January 25, 2009

INVISIBLE_TEXT

images-6Diagnostic imaging – whether it be X-rays, CT or MRI can significantly improve patient care and give us information that can aid in recovery. When it comes to X-rays, there is some evidence that misuse of the service occurs, whether it be overuse or under-use. It is for this reason that the Chiropractic College of Radiologists (Canada) created evidence-based Diagnostic Imaging Guidelines to be used by chiropractors and other health care professionals.

With respect to the low back and mid-back, the guidelines state that diagnostic imaging is required in the following circumstances:

INVISIBLE_TEXT
  • Mid-back or low back blunt trauma or acute injuries.
  • High-risk screening criteria for spinal injuries such as mid-line tenderness of the spine with palpation, altered consciousness or neurological problems.
  • Major trauma including pelvic trauma accompanied by inability to bear weight.
  • When spinal stenosis (narrowing of the canal the spinal cord or nerves run through) or other degenerative problems are suspected.
  • Lack of improvement with treatment, or worsening of the condition.
  • Presence of red flags – suspected underlying disease, infection or cancer, etc.

With respect to the neck, the guidelines state that diagnostic imaging is required under the following circumstances:

INVISIBLE_TEXT
  • Acute neck trauma in someone who is older than 65, reports a dangerous mechanism of injury OR has numbness/tingling/weakness in their arms.
  • Non-traumatic neck pain WITH pain/numbness/tingling or weakness in arms.
  • Lack of improvement with treatment, or worsening of the condition.
  • Presence of red flags – suspected underlying disease, infection, cancer, instability of the neck, etc.
INVISIBLE_TEXT

It should be noted that these guidelines do not recommend taking an X-ray of every patient who walks though the door. A large number of people have simple mechanical spine pain for which further imaging is not needed, thereby sparing the patient radiation exposure and the health care system more expense. However, there are some cases (as listed above) where it is prudent to get further investigation before proceeding with treatment. Your chiropractor is trained to be able to recognize when you warrant further diagnostic imaging.
