occur in less than 3 milliseconds, too quick for the body’s
nervous system and muscular structure to react and protect. This
leaves only bones and ligaments to protect the body. Since cervical
bones are rarely broken, the connective tissues are most commonly
injured.
Ligaments are the connective tissue that attach bone
to bone. The purpose of ligaments is to keep bones in proper position.
It has been suspected that ligaments are damaged easily, but until
now, it has been difficult to diagnose ligamentous injuries. DMX
can demonstrate these injuries.
Current research has found that after whiplash injury,
ligamentous injuries are extremely common in the cervical spine.
These ligamentous injuries are usually not complete failures (tears)
of a particular anatomincal structure, but represent, instead, sub-failure
injuries (stretched ligament). The decreased function and pain associated
with whiplash trauma may be explained by these sub-failure injuries.
Although static imaging methods such as MRI are sufficient for identifying
disc injuries, often they lack sufficient resolution to identify
these sub-failure injuries.
The number one complaint after whiplash injury is
posterior neck pain, (indicating possible Facet injury, or damaged
Capsular ligaments). The second most common complaint is headache,
stemming usually from C0-C1-C2 region of the spine (indicating possible
damage to Alar, Accessory or Transverse ligaments.) These two regions
are contained within the upper 30% of the cervical spine. The upper
30% of the cervical spine and posterior aspect of the cervical spine
contains no discs, just ligaments.
MRI is the gold standard for evaluating vertebral
discs. MRI routinely evaluates the anterior lower 70% of the cervical
spine, where the vertebral discs are located. The upper 30% of the
posterior aspect of the spine contains no discs. Thus, the MRI does
not evaluate the most common injuries from whiplash.
The DMX is the only diagnostic tool that specifically
addresses the number one and number two most common whiplash injury
complaints: neck pain and headaches. Digital Motion X-Ray is a valuable
diagnostic method in evaluating painful cervical instabilities due
to post traumatic pathology of the capsular and axial ligaments.
It is of primary importance in the care of the patient
to establish the presence of ligamentous damage, as these ligaments
heal slower and often don’t heal completely. Long term degenerative
damage can result from connective tissue injuries.
This new technology objectively and visually demonstrates
aberrant movement of bones allowing the radiologist to specifically
determine which ligaments or other soft tissues are injured.
DMX provides “demonstrable” or “observable”
evidence of the injury.
