Vertebral fractures and dislocations types

Vertebral anatomy.

Numbering order of vertebrae.

Clinical Features

C-spine injuries may present with

Rarely neurogenic shock (bradycardia, hypotension)
Posterior neck pain
Pain on palpation of spinous processes
Limited neck ROM with pain
Weakness, numbness, or paresthesias

Differential Diagnosis

Neck Trauma

Neck pain

Musculoskeletal
Torticollis
Dystonic reaction
Cervical spondylosis
Cervical stenosis
Cancer
Epidural abscess
Vertebral osteomyelitis
Transverse myelitis
Temporal arteritis
Epidural hematoma (anticoagulation, hemophilia)
Cervical disk herniation
Blunt neck trauma
Anterior horn disease
Cervical fractures and dislocations
Cervical radiculopathy

Evaluation

Plain films lines

See blunt neck trauma for general workup

Management

Prehospital
- See the NAEMSP National Guidelines for Spinal Immobilization
Hospital
- See page for specific fracture
- Cervical spine clearance

NEXUS Criteria

NEXUS Criteria for C-Spine Imaging
Criteria (ALL must be absent to clear)	Absent	Present
Posterior midline cervical tenderness	1
Focal neurologic deficit	1
Altered level of alertness	1
Intoxication	1
Distracting painful injury	1
Criteria Present	/ 5

Interpretation
0	C-spine can be cleared clinically — All 5 criteria absent. No imaging needed. Sensitivity 99.6% for clinically significant injury.
≥1	Cannot clear clinically — C-spine imaging indicated.

Canadian C-Spine Rule

Canadian C-Spine Rule
Step 1: Any High-Risk Factor? (mandates radiography)
Criteria	No	Yes
Age ≥65	1
Dangerous mechanism (fall ≥1m/5 stairs, axial load to head, MVC >100km/h or rollover/ejection, motorized recreational vehicle, bicycle collision)	1
Paresthesias in extremities	1
Step 2: Any Low-Risk Factor? (allows safe ROM assessment)
Simple rear-end MVC (excludes: pushed into traffic, hit by bus/large truck, rollover, hit by high-speed vehicle)	1
Sitting position in ED	1
Ambulatory at any time since injury	1
Delayed onset of neck pain (not immediate)	1
Absence of midline cervical tenderness	1
Step 3: Able to actively rotate neck 45° left and right?
Can rotate neck 45° L and R	1
High Risk Factors	/ 3
Low Risk Factors	/ 5

Interpretation (stepwise)
High risk ≥1	Radiography indicated — Do NOT assess ROM. Image the c-spine.
Low risk = 0	Cannot assess ROM safely — No low-risk factor present to allow safe assessment. Image.
Low risk ≥1 + ROM OK	C-spine can be cleared — At least one low-risk factor AND able to rotate neck 45°. No imaging needed.
Low risk ≥1 + no ROM	Radiography indicated — Low-risk factor present but unable to rotate. Image.
