Cervical spinal injury
patients may have more damage left undetected
Patients
who come to the emergency room with cervical spinal
injury may have more
damage than what is detected. In a study, which is published
in the Annals of Emergency Medicine, say that CT imaging
may be useful to detect such injuries in patients over
and above the normal X-rays.
The study indicates
that patients with a cervical spinal injury (CSI) may
harbor additional spinal damage not visible on regular
x-rays. In fact, more than a third of patients who were
thought to have low-risk injuries actually have additional
damage that may include significant fractures with the
potential to produce serious spinal problems if not
detected and treated properly.
This study stands in
the face of previous medical thinking in which patients
with certain forms of spinal injury were considered
at very low risk of having additional injuries.
Because of that low
risk, physicians were urged to use plain x-rays and
avoid computed tomography (CT) in evaluating these cases.
Researchers reviewed
patient cases from the National Emergency X-Radiography
Utilization Study (NEXUS), which was conducted at 21
centers across the United States.
Study authors found
that x-rays failed to detect secondary injuries in 81
of the 224 patients identified with cervical spine injuries
– or 36 percent.
The researchers
believe that patients with any evidence of cervical
spine injury, including those with cervical spine injuries
previously considered to be at low risk for secondary
injuries, should undergo CT imaging of the entire cervical
spine.
CT should be
obtained both to determine whether secondary injuries
are present and to identify those non-contiguous injuries
that, in fact, occur in a substantial number of cases.
