One of the most difficult situations in personal injury litigation is the client who continues to experience severe neck pain, headaches, dizziness, or neurological symptoms months after a motor vehicle collision — yet every MRI report says the same thing:
“No acute findings.”
For attorneys, these cases can quickly become frustrating.
The defense argues:
- “There’s no objective injury.”
- “The imaging is normal.”
- “This is just subjective pain.”
- “The crash was too minor to cause permanent damage.”
But as discussed extensively in The $66,000 Neck Injury and How Not to Be Misdiagnosed, some of the most significant whiplash injuries are not compression injuries at all.
They are ligament injuries.
And unless spinal motion is properly measured, those injuries may never be identified.
The Problem with Traditional Imaging
MRI and CT scans are designed to identify:
- Disc herniations
- Fractures
- Spinal cord compromise
- Major structural abnormalities
What they do not reliably measure is functional instability.
That distinction is critical.
A patient may suffer significant damage to the cervical ligaments responsible for stabilizing the spine during motion, yet still have:
- Normal MRI findings
- Minimal CT abnormalities
- Negative static X-rays
This is because the injury only becomes visible when the neck moves.
As emphasized throughout the book, a static image cannot accurately evaluate dynamic instability.
What CRMA Actually Does
CRMA — Computerized Radiographic Mensuration Analysis — is designed to measure cervical motion segment instability objectively.
Using flexion-extension radiographs, CRMA evaluates:
- Vertebral translation
- Angular displacement
- Abnormal intersegmental movement
These measurements are then compared against accepted biomechanical standards and AMA impairment thresholds.
When motion exceeds accepted values, the patient may meet the criteria for:
Alteration of Motion Segment Integrity (AOMSI)
This is significant because AOMSI is recognized within the AMA Guides as a ratable impairment category — not merely a pain complaint.
Why This Changes the Litigation Conversation
In many whiplash cases, the defense position is built around one assumption:
“No objective findings equals no serious injury.”
CRMA directly challenges that assumption.
The book repeatedly explains that ligament injuries can create:
- Excessive spinal movement
- Chronic instability
- Neurological irritation
- Long-term functional impairment
without producing obvious findings on MRI.
CRMA provides measurable evidence of that instability.
For attorneys, this can:
- Strengthen causation arguments
- Support permanency claims
- Reinforce impairment ratings
- Counter “minor impact” defenses
- Improve settlement leverage
Why Vehicle Damage Often Misleads Juries
One of the major themes discussed in The $66,000 Neck Injury is that vehicle damage does not reliably predict cervical injury severity.
Low-speed collisions can still generate:
- Rapid acceleration-deceleration forces
- Ligament strain
- Capsular injury
- Spinal instability
Yet defense experts frequently equate minimal property damage with minimal bodily injury.
CRMA helps shift the discussion away from bumper damage and toward measurable biomechanics.
Instead of:
“The car barely had damage.”
the discussion becomes:
“Here are objective measurements showing pathological spinal instability.”
That is a very different courtroom conversation.
Why So Many Cases Go Undiagnosed
Most emergency rooms and primary providers do not routinely evaluate for cervical instability.
Common reasons include:
- No flexion-extension films ordered
- Lack of training in AOMSI evaluation
- Overreliance on MRI findings
- No CRMA analysis performed
As a result, patients are often labeled with:
- “Whiplash”
- “Cervical strain”
- “Soft tissue injury”
without any investigation into whether instability exists.
The book’s core warning is that these injuries are not necessarily uncommon — they are simply missed.
When Attorneys Should Consider CRMA
CRMA may be worth evaluating when a client:
- Has persistent symptoms despite conservative care
- Complains of chronic headaches or dizziness
- Reports instability or difficulty holding the head upright
- Has “normal” MRI findings despite ongoing dysfunction
- Was involved in a flexion-extension collision
- Continues treating months after the accident
In these cases, the absence of MRI findings should not automatically end the investigation.
The Importance of Objective Documentation
In litigation, subjective complaints alone are often insufficient.
Jurors, adjusters, and defense experts frequently want:
- Measurements
- Quantifiable findings
- Objective evidence
CRMA helps bridge that gap by converting motion abnormalities into measurable data.
As discussed throughout The $66,000 Neck Injury, the issue is not simply whether the patient hurts.
The issue is whether instability can be objectively demonstrated.
Our Role
As a chiropractor trained in ligament injury analysis and spinal biomechanics, I evaluate whiplash cases for:
- Cervical instability
- AOMSI
- CRMA findings
- AMA impairment criteria
I also provide:
- Record reviews
- Narrative reports
- Imaging interpretation
- Expert witness testimony throughout Allegheny County, PA
Final Thought
A normal MRI does not always mean a normal cervical spine.
In many whiplash cases, the real injury is not what appears on a static image — it is what happens during motion.
And unless motion is properly analyzed, the most important injury in the case may never be documented.
