Cervical Spine Examination
The cervical spine examination must differentiate between radiculopathy (nerve root) and myelopathy (spinal cord). Examiners expect you to identify red flags, perform provocative tests (Spurling's), and complete a thorough neurological assessment. Always exclude the shoulder as a source of referred pain.
Quick Reference One-Pager

- Upper limb neurological exam
Introduction and Setup
Before You Start
Patient Positioning: Seated for most of examination, standing for gait assessment
Exposure: Neck and upper back exposed, arms exposed for neurological examination
Consent Script: "I'm going to examine your neck. I'll look at the posture, feel the spine, and test the movements. I'll also check the nerves in your arms. Please tell me if anything causes pain or unusual symptoms."
Key Anatomy:
- 7 cervical vertebrae (C3-C7 have similar structure)
- C1-C2 (atlantoaxial) provides 50% of rotation
- 8 cervical nerve roots (C1-C8)
- Nerve root exits ABOVE corresponding vertebra (C6 root exits at C5-C6 level)
Red Flags (Screen First)
Red Flags in Cervical Spine Pain - Exclude Before Proceeding:
- Myelopathy symptoms: Gait disturbance, hand clumsiness, urinary symptoms
- Trauma: Any significant mechanism, especially in elderly
- Constitutional symptoms: Fever, weight loss, night sweats (infection, malignancy)
- Progressive neurological deficit: Increasing weakness or sensory loss
- Severe unrelenting pain: Not relieved by rest (tumor, infection)
- Age over 50 with new onset: Consider metastatic disease
- Known malignancy: Spinal metastases
- Immunocompromised: Infection risk
Look (Inspection)
- Head position: Forward head posture, tilt, rotation
- Shoulder height: Asymmetry (torticollis, scoliosis)
- Supraclavicular fossae: Fullness (Pancoast tumor, nodes)
- Thyroid: Enlargement
- Muscle bulk: SCM, scalenes
Loss of Cervical Lordosis: Often indicates muscle spasm from acute injury or disc pathology. May also be seen in ankylosing spondylitis (where entire spine becomes kyphotic) or post-laminectomy.
Feel (Palpation)
Systematic Palpation Sequence
Posterior Midline:
- Occiput: Nuchal ridge, occipital nerves
- C2 spinous process: First palpable spinous process
- C3-C6: May be difficult to distinguish individually
- C7 (vertebra prominens): Most prominent spinous process
- T1: For reference
Posterior Lateral:
- Facet joints: 1-2cm lateral to midline
- Paraspinal muscles: Spasm, tenderness, trigger points
- Trapezius: Upper fibers
- Levator scapulae: Scapular angle
Anterior Lateral:
- SCM muscle: Spasm, tenderness
- Scalene muscles: Trigger points
- Lymph nodes: Cervical chain
- Thyroid: Enlargement
- Carotid pulse: Assess before mobilization
Special Palpation:
- Supraclavicular fossa (Pancoast tumor, nodes, brachial plexus)
- Spinous process step-off (spondylolisthesis, fracture)

During Movement Assess:
- Pain: Location, reproduction of arm symptoms
- Crepitus: Degenerative changes
- Apprehension: Instability
- Arc of pain: Specific position that causes symptoms
Combined Movements: In cervical radiculopathy, extension combined with rotation toward the affected side (Spurling's position) compresses the foramen and reproduces symptoms. This is more sensitive than individual movements.
