Ligament Laxity

Step 1 – Identify


George’s Line is evaluated on a lateral x-ray of the cervical spine.
It is simply a line drawn on the posterior of each vertebral bodyalong the entire cervical spine. Any disruption of this line is indicative of Ligament Laxity. The cause of this laxity develops through similar mechanisms, which leads to excessive motion of the facet joints, and will cause various degrees of physical impairment/degeneration.

If any break in the line is identified then Flexion and Extension
films should be taken to accurately measure the amount of
translation that is occurring.

Ligament Laxity happens as a result of a macrotrauma such as:

  • Motor Vehicle Accidents
  • Repetitive use injuries
  • Work-related injuries

This condition is commonly overlooked and yet can offer your case great value in your impairment rating.

Step 2 – Quantify


DXD Software

  • DXD software uses X-ray image overlay technology and qualifies as “Evidence Based Objective Impairment Rating”.
  • The DXD software correlates with the AMA Guidelines 4th, 5th and the 6th Editions.
  • Results of the data from the above x-rays is documented in the chart below.
  • Computed Radiographic Mensuration Analysis used to determine

Step 3 – Document

AMA Guides to the Evaluation of Permanent Impairment
Cervical Spine Ligament Laxity Criteria

  • Abnormal integrity of the motion segment present on flexion and extension radiographs.
  • Findings of 3.5mm or greater of translation of one vertebra on another.
  • Angular motion of more than 11 degrees greater than at each adjacent level.
  • Results in a 25% to 28% Cervical Impairment Rating of the whole person.

Lumbar Spine Ligament Laxity Criteria

  • Abnormal integrity of the motion segment present on flexion and extension radiographs.
  • Findings of 4.5mm or greater of translation of one vertebra on another.
  • Angular motion greater than 15 degrees at L1-2, L2-3, and L3-4
  • Angular motion greater than 20 degrees at L4-5
  • Angular motion greater than 25 degrees at L5-S1
  • Results in a 20% to 23% Lumbar Impairment Rating of the whole person

How does this help your case?

Using the AMA Guidelines, we are providing your case with an irrefutable impairment rating report which will be accepted as the Gold Standard. This will maximize your case value.
Because we are using computer mensuration we minimize the degree of error when evaluating the radiographic studies.
