Cervical Spine Flashcards
Atlas (C1)
• 1st vertebrae • No vertebral body • No true spinous process • Transverse process • Transverse foramen • Supports the weight of the head through the atlanto-occipital joint (C0-C1). • Primary movement flexion/extension
Axis (C2)
• 2nd vertebrae • Small vertebral body with superior projection (Dens) • Spinous process • Transverse process • Transverse foramen • Atlanto-axial joint • Dens and atlas articulation • Pivot joint • Primary movement rotation of the skull
Uncinate processes of the cervical spine
- Bony elevations on the superior lateral margin of the cervical vertebrae
- Uncovertebral joints • Joints of Luschka
- Prevent posterior linear translation of vertebral bodies
- Reinforces the disc posterolaterally
- Limits lateral flexion
Brachial plexus nerve roots
C5-T1
Red flags for Cervical Spine
• Major Trauma • Neoplasm • Systemic inflammatory diseases and infections • Cervical myelopathy • Previous neck surgery • 5D’sand3N’s • Neurological symptoms including upper or lower limb clumsiness, uncoordinated movements
Indications of cervical trauma
- Complains of consistent, severe, neck pain.
- Increase in pain and decrease of movement on examination.
- Signs of neurological injury
- Requires urgent MRI, CT or radiological referral
VBI
- …a condition characterized by a temporary set of symptoms due to a decrease blood flow to the posterior portion of the brain. This is fed by two vertebral arteries that travel within the transverse foramen and join to become the basilar artery.
- Atherosclerosis
- Spondylosis (Osteophyte formation)
- Trauma
- Occlusion may occur during sudden or sustain movements of the head or neck
VBI subjective questioning
- In EVERY patient presenting with upper quadrant dysfunction, questioning is specifically directed to elicit the presence of symptoms related to VBI. This is completed prior to assessment and treatment of the cervical spine.
- The 5 D’s and 3 N’s • Dizziness
- Diplopia (Double vision) • Dysarthria
- Dysphagia
- Drop attacks
- Nausea (vomiting), Numbness (neurological), Nystagmus
VBI objective tests
• Minimum test include
• Sustained end range rotation technique L) and R) (ERRT)
• The position or movement which provokes symptoms
• All positions sustained for 10 seconds unless symptoms provoked sooner
• Therapist watches the patients eyes for nystagmus while the head is sustained and questions the patient on symptom reproduction.
• On return to neutral from sustained position a period of 10 seconds should be allowed before continuing onto the next position.
• Other Tests
• Cervical Extension
• Cervical rotation combined with extension
• Simulated manipulation position
• Quick movement of the head through the available range (patient dependant)
NOTE: This is done prior to ERRT or HVT (Manipulation)
Possible structures involved in cervical spine
- Muscle •Z joint
- Bone
- Ligament • Disc
- Vascular • Neural
regional disorders of Cx (upper, mid, lower)
- Upper cervical spine
- frequently cause of cervicogenic headaches
- Mid cervical spine
- commonly involve zygapophyseal joint dysfunction
- Lower cervical spine
- most frequent region for discogenic disorders and spinal nerve/nerve root compromise
WAD MOI
- Acceleration - deceleration injuries of the cervical spine
- Rapid hyperextension to hyperflexion movement +/- shear forces
- Can also involve rotational and lateral shear forces depending on impact
- Speed of impact and force of impact exceed capacity of tissue to cope which leads to failure of the tissues.
Clinical presentation of WAD
Dependent on severity of injury • Neck Pain • Headache • Decreased neck mobility • +/- thoracic, shoulder pain • Arm pain Note: • Delay in the onset of symptoms • Not to be missed: Fracture & vertebral artery injury • Chronicity • Depression, anxiety, dependence, psychosocial problems • Liability issues – Legal matters etc. • Dizziness, tinnitus, blurred vision
Clinical dx of WAD Hx taking
History Taking • All of your normal information • Age, sex, occupation etc etc. • Prior history of WAD • Prior history of long term disability • MOI of injury in detail • OUTCOME MEASURES • NDI • General Health Questionnaire
Clinical Dx of WAD physical exam
Physical Exam
• Observation
• Palpation
• ROM (Active and Passive) • Neurological Assessment
• Assessment of any other injuries (e.g. shoulder)
Recommended Rx of WAD
- Reassure and stay active (Normal ADL’s)
- Exercise
- ROM, low load isometrics, postural endurance, strengthening
- Pharmacology
- Simple analgesics
- NSAIDs Refer to pharmacist • Opioid analgesics
- Manual Therapy (may be effective)
- Manipulation (Thoracic Spine)
- No evidence for efficacy of C spine manipulation in the treatment of acute WAD
Prognosis of WAD
Things that can impact on prognosis:
• Symptom severity (>5/10 VAS; >15/50 NDI)
• Physical symptoms (e.g. decreased initial neck ROM, cold hyperalgesia)
• Psychological factors
• Do you think you will get better soon?
• Posttraumatic stress (PTS) symptoms using the Impact of Events Scale (IES)
• Socio-demographic factors
• NOT predictive of ongoing pain
Acute Wry Neck
- Sudden onset of sharp neck pain with protective deformity and limitation of movement.
- Typically caused after a sudden quick movement or on waking from sleep.
- Two common types of Acute Wry Neck • Zygapophyseal wry neck
- Diskogenic wry neck
Zygoapophyseal Wry Neck Presentation
- Most common in children and young adults
- Most common at C2-C3 level
- Associated with sudden movement resulting sharp pain
- Locking of C0-C1 or C1-C2 may result from some form of trauma
- Posture away from pain (lateral flexion and slight flexion)
- Limited ROM
Zygoapophyseal Wry Neck Rx
- Soft tissue techniques
- Joint mobilisations/manipulation • AROM/PROM (if permitted)
- Traction
- EPAs (Heat)
- Reassure, Advice and Education
- Home Exercise
- ROM exercises
- Motor control exercises
- Posture
- Advice about cervical support during sleep
Diskogenic Wry Neck Presentation
- More gradual onset compared to Z-joint wry neck
- Most common after waking from long sleep
- Most common in older group (e.g. middle aged adults)
- Typically lower cervical or upper thoracic
- Posture away from pain (lateral flexion , rotation and slight flexion)
- +/- referred to scapular region
Diskogenic Wry Neck Rx
- Important to differentiate between Z-joint and Diskogenic as manipulation may result in provocation of symptoms in these individuals
- Gentle traction
- Soft tissue techniques
- Gentle mobilisations
- EPAs (Heat)
- Reassure, Advice and Education
- Temporary soft collar
- Motor control exercises as tolerated
- Postural retraining as tolerated
- Advice about cervical support during sleep
Cx Spondylosis
- Refers to degeneration of the spine, typically associated with the aging process.
- Degeneration of the disc – prolapse/breakdown • Joint space narrowing
- Osteophyte formation
- Spinal stenosis
- Foramen stenosis
Spondylosis Clinical presentation
- Most people don’t have significant symptoms • Neck and/or arm pain
- Stiff neck
- Headaches
- Radiculopathy-nerve root compression • Neurological symptoms (unilateral)
- Myelopathy-spinal cord compression • Neurological symptoms (bilateral)
- Diagnosis
- Patient history
- Imaging (CT, MRI, X-ray)
Spondylosis Clinical Rx
- Surgery
- Potential to refer for decompression surgery depending on severity of symptoms
- Soft tissue
- Muscle strengthening • Traction
- Stretching
- ROM exercises
- Advice & Education
- Reassurance
- Medication
- Alternative therapies • Dry needling
- Heat
Craniovertebral Instability
- Excessive movement at C1-C2 vertebrae as a result of bony or ligamentous abnormality
- Neurological symptoms can occur when the spinal cord or adjacent nerve roots are involved.
- Causes
- Acute Trauma
- Degeneration
- Congenital conditions
Craniovertebral Instability Presentation
- Neck pain
- Wry neck posture • Headache
- Myelopathy
- Cord compromise signs and symptoms:
- Difficulty walking & clumsiness with hands • Lack of coordination
- Bowel & bladder dysfunction
- Positive Babinski & ankle clonus
- Hyperreflexia
- Spasticity
- Vascular symptoms
- Feeling of instability (something isn’t right?)
Craniovertebral instability Dx
- Severe signs and symptoms and acute trauma require urgent referral for diagnostic imaging
- Radiography
- CT
- MRI
- Neurological examination
- Damage to alar ligaments can increase rotation by up to 30% - frank instability
Cervical Radiculopathy
- A compression of the nerve root as it exists the vertebral column of the cervical spine.
- Trauma
- Disc issues – younger population
- Spondylosis – older population
