Cervical spine claim
Neck and cervical spine injury after a motor accident
A cervical claim may involve soft tissue strain, facet injury, disc pathology, nerve-root dysfunction, fracture or spinal cord injury. Each diagnosis has a different threshold and WPI consequence, so the file should not reduce every neck complaint to whiplash or every MRI change to radiculopathy.
Motor accident mechanism
What can happen in a motor accident?
Rear-end crash
Rapid flexion and extension can affect cervical soft tissue, facets, discs and foraminal structures.
Side-impact crash
Rotation and lateral loading may produce asymmetric facet, disc or nerve-root findings.
Motorcycle fall
Helmet or shoulder impact can transmit axial load into the cervical spine and may cause fracture or cord injury.
Pedestrian impact
Direct vehicle impact and ground contact can combine rotation, compression and direct cervical trauma.
Injuries and diagnoses that may follow
- cervical sprain or facet injury
- disc protrusion or foraminal stenosis
- cervical radiculopathy
- vertebral fracture or dislocation
- cervical myelopathy or spinal cord injury
Symptoms that should be recorded accurately
- neck and shoulder-blade pain
- arm pain or hand tingling
- grip or focal muscle weakness
- headache and reduced neck tolerance
- hand clumsiness, gait change or widespread neurological symptoms where cord involvement is suspected
Urgent medical signs
Sudden or progressive weakness, gait change, hand clumsiness after major trauma or suspected spinal cord compression requires urgent medical assessment.
Clinical evidence
What medical findings matter?
Cervical examination should identify whether symptoms are local, referred, nerve-root based or central. Upper-limb power, sensation and reflexes should be mapped to the suspected level.
| Record or test | What it can establish | What it cannot establish alone |
|---|---|---|
| Cervical neurological exam | Assesses biceps, brachioradialis and triceps reflexes, myotomal power, dermatomal sensation and upper motor-neurone signs. | A global weak grip caused by pain does not establish root weakness. |
| MRI or CT | Shows disc, foraminal, canal, fracture or cord pathology at a stated level. | The level must match the clinical distribution and accident history. |
| X-ray | Can identify alignment, fracture or dislocation and may support structural assessment. | Normal X-ray does not resolve soft tissue or nerve-root questions. |
| Operative report | Identifies decompression, fusion or disc replacement levels and surgical findings. | The procedure does not produce an automatic DRE category or WPI percentage. |
Part 5 classification
Is this likely to be threshold or non-threshold?
Cervical sprain, facet pain and non-verifiable arm symptoms may remain threshold. Verified radiculopathy, fracture, cord injury or another excluded structural injury may support non-threshold classification. The diagnosis and clinical findings matter more than the general label neck injury.
Evidence that may support a threshold classification
- soft tissue sprain without rupture
- local or referred neck pain without nerve dysfunction
- non-verifiable arm pain or tingling
- disc findings that do not correlate clinically
Evidence that may support a non-threshold injury
- two or more anatomically consistent radiculopathy signs
- fracture or dislocation
- spinal cord injury or objective myelopathy caused by the accident
- verified nerve injury or excluded rupture
Radiculopathy means two or more clinical signs, not pain alone
Clauses 5.7-5.9 and 6.138-6.142 require dysfunction of a spinal nerve root with two or more of the following signs found on examination:
- 1.loss or asymmetry of reflexes
- 2.positive sciatic nerve-root tension signs
- 3.muscle atrophy or decreased limb circumference
- 4.muscle weakness anatomically localised to the appropriate spinal nerve-root distribution
- 5.reproducible sensory loss anatomically localised to the appropriate spinal nerve-root distribution
Pain, burning or tingling that follows a nerve-root pattern but lacks objective neurological findings is a non-verifiable radicular complaint under Table 6.8. If the neck or spine symptoms do not meet the radiculopathy criteria, clause 5.9 says the injury is assessed as threshold.
Part 6 permanent impairment
How is WPI assessed for this injury?
Cervical spine WPI uses the cervicothoracic DRE descriptors in AMA4 pages 103-105, modified by Part 6. The assessor must apply Table 6.7 and Table 6.8, not the ROM model or loss of motion segment integrity.
CTP spine method: clause 6.111 requires the DRE method. The spinal ROM model and AMA4 Table 75 are not used, and clause 6.123 says loss of motion segment integrity is not applied.
| Category | Human-language guide to the verified CTP rule |
|---|---|
| DRE I | Symptoms are present, but the medical assessor finds no objective clinical findings that place the injury in a higher category. This is the rule stated in clause 6.129. |
| DRE II | The assessor finds qualifying clinical findings, such as guarding, reproducible non-uniform motion or non-verifiable radicular complaints, or a specified stable fracture pattern, but not verified radiculopathy or a higher structural inclusion. |
| DRE III | This category includes verified radiculopathy and specified fracture or dislocation patterns identified in Table 6.7. Radiating pain without the required neurological signs is not enough. |
| DRE IV | This is a higher structural category. One verified example is multiple qualifying vertebral fractures without radiculopathy under clause 6.151(a). Fusion and disc replacement are treated as multilevel structural compromise under clause 6.145, but surgery does not by itself supply a fixed percentage. |
| DRE V | This is the higher structural category where the applicable descriptor includes radiculopathy. Clause 6.151(b), for example, places multiple qualifying vertebral fractures with radiculopathy in category V. |
A DRE category is not a percentage to calculate from symptoms. The assessor must use the region-specific AMA4 descriptors on pages 102-107 as modified by clauses 6.125-6.132 and explain the tables or figures used, as required by clause 6.122.
- Choose the highest applicable DRE category within the cervical region.
- If there is spinal cord pathology, the associated DRE may be combined with nervous-system impairment under clause 6.161.
- C2 or C3 sensory loss has the special rule in clause 6.139.
- Pre-existing cervical degeneration or surgery requires a reasoned causation and deduction analysis.
What does not establish the result by itself?
- neck pain and reduced movement alone
- a positive MRI without matching clinical signs
- global arm weakness from pain inhibition
- a surgery name without operative findings and DRE analysis
Accident-specific examples
Rear-end crash with local neck and shoulder-blade pain
Without an excluded injury or qualifying radiculopathy, this may remain a threshold soft tissue injury and may fit DRE I or II depending on the assessor findings.
C6 symptoms with reflex asymmetry and focal wrist weakness
These may be two qualifying signs if reproducible and anatomically localised. A matching C5-6 foraminal lesion can support the diagnosis but does not replace the signs.
Motorcycle fall with cervical fracture and hand clumsiness
The fracture and possible cord involvement require separate structural and nervous-system assessment rather than a whiplash template.

Assessment source
Cervical spine threshold and WPI source
Assessment source: Motor Accident Guidelines v10.1 clauses 5.7-5.9, 6.111-6.142, Tables 6.7 and 6.8; AMA4 cervicothoracic DRE descriptors as modified by clauses 6.125-6.132.
Threshold injury: Local cervical soft tissue symptoms may be threshold. Verified radiculopathy, fracture, cord injury or another excluded injury requires diagnosis-specific assessment.
What the assessor checks
- DRE only
- ROM/Table 75 prohibited
- two-sign radiculopathy rule
- special C2/C3 sensory-loss rule
What does not establish the result by itself
- pain alone
- MRI alone
- global weakness
- operation alone

Frequently asked questions
- Is every cervical disc injury non-threshold?
- No. The evidence must establish an injury outside the soft tissue definition. A scan finding alone is not enough.
- What is cervical radiculopathy?
- It is dysfunction of a cervical nerve root supported by at least two specified clinical signs, not arm pain alone.
- Can myelopathy be assessed like radiculopathy?
- No. Spinal cord or central nervous-system pathology requires the nervous-system method and may be combined with the associated DRE under clause 6.161.
- Does fusion decide the WPI?
- No. Fusion is treated as multilevel structural compromise, but the category and percentage still require the modified DRE analysis.
- Which records matter most?
- Early neurological findings, level-specific imaging, specialist reasoning, operative reports and consistent follow-up examinations.
