What is the Digital Motion X-ray?

The Digital Motion X-Ray (DMX) is a new type of fluoro-based x-ray system, coupled with new digital and optic technology, allowing clinicians to view the spine in real-time motion at 30 x-rays per second. The procedure is performed with the patient standing and actively moving in a weight-bearing position within the system.

Don’t flexion-extension X-Rays show all ligamentous injuries?

We are taught in school that cervical flexion/extension x-rays were all we needed to rule out ligamentous injury. The truth is, these x-rays are taken during one arc of motion, at end points. This evaluates only 2 of the 22 major ligaments of the cervical spine. DMX allows us to evaluate all 22 major ligaments of the cervical spine with 2,700 x-ray images. The only two ligaments the flexion/extension x-rays may detect if patient positioning is proper, are the anterior and posterior longitudinal ligaments. The ligaments that are not diagnosed are the:

  • Right and left alar ligaments
  • Right and left accessory ligaments
  • Transverse ligament
  • Five right capsular ligaments
  • Five left capsular ligaments
  • Five interspinous ligaments

What is the difference between a DMX and an MRI?

DMX is a new type of x-ray system that allows the clinician to take x-rays while the patient moves in a standing weight-bearing position. DMX evaluates the bones in motion allowing us to detect which specific ligaments have been injured. If you hurt more when you move, then you must be diagnosed while you move.

MRI of the cervical spine is designed to evaluate disc injuries while not moving, lying down, and not swallowing. The symptoms of a cervical disc injury are usually numbness and tingling in the upper extremities. The upper 30% of the spine and posterior aspect of the spine contain no discs, just ligaments. Headaches and posterior neck pain are commonly caused by stretched ligament injuries which cannot be detected by MRI.

What is the radiation exposure?

The DMX system can produce 2,700 x-ray images with the same amount of radiation as a standard x-ray machine, which gives you 6 static x-rays.

Does insurance cover this type of procedure?

We follow a simple rule: If the insurance company reimburses you for static x-rays, there is no reason why they wouldn’t reimburse you for an x-ray that moves.

How does the DMX help attorneys settle cases?

The DMX provides demonstrable and observable evidence of the injury. Which helps an attorney prove whether or not the victim has permanent ligimentous damage.

How does Digital Motion X-Ray improve patient care?

It let’s you see the injury in ways you’ve never seen it before. Hidden injuries are revealed, helping the doctor design a more effective treatment plan for the patient based on a more complete diagnosis.

Why Doesn’t my local Doctor or Radioligist know about the DMX?

Since the DMX is new, the medical professionals are in the early stages of awareness and learning about the technology and most facilities do not have DMX equipment.

Why do we need moving X-rays?

With the use of moving x-rays, we can visualize spinal mechanical abnormalities that may not be revealed on still images.

What injuries are revealed through DMX that may not be revealed through a traditional x-ray or MRI?

DMX was developed specifically for revealing injuries which occur from motion. An example would be a case where the spine is violently put in motion such as a rear impact vehicle crash. Studies have shown that a high percentage of ligament damage occurs in such a case. The supportive ligaments (Alar and Accessory ligaments) which hold the head on the top of the spine are commonly damaged. New studies indicate that when these ligaments are torn away from the base of the skull, it leads to painful instability. If this damage occurs, it can be irreversible and leads to chronic pain at the base of the skull and severe headaches. Another example would be an injury suffered to the lower cervical spine ligaments that hold the spinal joints together. Irreversible damage to these ligaments (Capsular ligaments) results in cervical spine instability as well as pain in the neck and shoulders. Traditional x-rays or even regular MRI (Magnetic Resonance Imaging) will not reveal these injuries but DMX has been developed specifically to screen these areas.

Why won’t my regular neck x-rays show the injury or abnormality?

Typically, regular x-ray images of the neck consist of a series of 3 views. The 3 regular views are taken while the patient is completely still. Some injuries or abnormalities do present themselves on these still images but unfortunately, many do not. A Digital Motion X-Ray series will typically have at least 2700 separate views taken while the spine is in motion. Motion x-rays are taken from thousands of different angles. The probability of revealing the injury are proportionately greater with the number of images captured, especially when combined with the actual motion of the spine and the resulting interaction of the skeletal structure.
