Study Notes

Early Presenting Features

Acute neck pain and headache may mimic musculoskeletal conditions.
Important risk factors include minor trauma, infections, genetic predisposition, and potentially migraines.

Cervical Arterial Dissection (CAD)

CAD often presents in those under 65 but can occur in younger populations.
Commonly associated with chronic neck pain and stiffness.
Symptoms related to neck movement and positions.
Potential causes include atherosclerosis, spondylosis (osteophyte formation), trauma, and occlusion during neck movements.

Vertebrobasilar Insufficiency (VBI) Questioning

In patients with upper quadrant dysfunction, all must be screened for VBI symptoms.
Specific focus on the "5 D's" (Dizziness, Diplopia, Dysarthria, Dysphagia, Drop attacks) and "3 N's" (Nausea, Numbness, Nystagmus).

VBI Testing

VBI positional tests used when symptoms are ambiguous; cease if symptoms worsen.
Minimum tests include sustained end range rotation to evaluate symptoms.
Positive tests observed include dizziness and nystagmus that doesn't resolve quickly.

Odontoid (Dens) Fracture

Classified using the Anderson and D’Alonzo system.
Important for understanding fracture implications and management.

Fractures of the Cervical Spine

Hangman's fracture refers specifically to a fracture of the C2 vertebra's pedicles.
The AO Spine Classification categorizes lower cervical fractures into three types:
- Type A (Compression): A1 (Impaction), A2 (Split), A3 (Burst)
- Type B (Distraction): B1 (Posterior injury), B2 (Combination), B3 (Anterior distraction)
- Type C (Rotation): C1 (Unilateral facet fracture-dislocation), C2 (Unilateral facet dislocation), C3 (Separation with combination fractures)

Craniovertebral Instability Presentation

Common symptoms include neck pain, wry neck posture, headaches, and signs of myelopathy, such as difficulty walking and loss of coordination.
Vascular symptoms and a feeling of instability may also be present.

Craniovertebral Instability Diagnosis

Severe signs or acute trauma necessitate urgent imaging referral.
Alar ligament tests are crucial for diagnosis and assessment of instability.

Description

This quiz covers the early presenting features and risk factors associated with Cervical Arterial Dissection (CAD). It highlights the importance of recognising clinical symptoms that may resemble musculoskeletal presentations, such as acute neck pain and headache. Understanding these factors is crucial for safe manual therapy practice in the cervical spine.
