Q

Why does dehydration of the intervertebral discs contribute to cervical spondylosis?

A

It allows for more bone-to-bone contact between the vertebrae

22
Q

When should radiculopathy be suspected in cervical spondylosis?

Study These Flashcards
A

When there is unilateral neck, shoulder or arm pain approximating to a dermatome

23
Q

What accompanying symptoms can be seen in radiculopathy?

Study These Flashcards
A
  • Changes in sensation
  • Weakness in related muscles
  • Diminished reflexes at appropriate level
24
Q

What investigations may be used to assess cervical spondylosis?

Study These Flashcards
A
  • X-ray of cervical spine

- MRI

25
What might an x-ray of the cervical spine show in cervical spondylosis?
Narrowing of the disc spaces with encroachment of the intervertebral foraminae
26
Is narrowing of the disc spaces with encroachment of the intervertebral foraminae on cervical x-ray diagnostic of cervical spondylosis?
No, they can be common in middle aged patients
27
When is an MRI necessary in cervical spondylosis?
In a patient with neurological abnormality especially, progressive myelopathy, radiculopathy or intractable pain
28
What are some differentials of cervical spondylosis?
- Non-specific neck pain lesions - Malignancy - Infections - Mechanical lesions - Fibromyalgia - Psychogenic neck pain - Inflammatory disease e.g. RA - Metabolic disease
29
What other non-specific neck pain lesions may present like cervical spondylosis?
- Acute neck strain - Postural neck ache - Whiplash
30
What malignancies are differentials for cervical spondylosis?
- Primary tumour of bone - Metastases - Myeloma
31
What infections are differentials for cervical spondylosis?
- Osteomyelitis | - Tuberculosis
32
What mechanical lesions may present like cervical spondylosis?
Disc prolapse
33
What metabolic diseases are differentials for cervical spondylosis?
- Paget's disease of bone | - Osteoporosis
34
What red flag symptoms suggest malignancy or infection rather than cervical spondylosis?
- Fever or chills - Weight loss - Relentless nocturnal pain - History of cancer - Immunosuppression
35
What symptoms are red flags for myelopathy instead of cervical spondylosis?
- Insidious progression - Gait disturbance - Loss of sexual, bladder or bowel function - Lhermitte's sign
36
What is Lhermitte's sign?
Neck flexion causes electric shock type sensation radiating down the spine
37
How should symptoms of cervical spondylosis be managed in the first 4 weeks?
With reassurance, advice to keep active and avoid use of a cervical collar.
38
What concerns may patients with cervical spondylosis have that should be addressed?
Fear of chronic disability
39
What treatment should be considered for prolonged (4-12 weeks) symptoms of cervical spondylosis?
Referral to physiotherapy for 'mechanical' treatment
40
What treatment should be considered for patients with chronic (>12 weeks) symptoms of cervical spondylosis?
- Referral to pain clinic | - Referral for surgery
41
What mechanical interventions can be performed by physiotherapists for cervical spondylosis?
Manipulation of the neck
42
What are the risks of mechanical intervention cervical spondylosis?
- Arterial dissection - Myelopathy - Vertebral disc extrusion
43
What pharmacological agents can be used to treat symptoms of cervical spondylosis?
- Analgesics - Anti-inflammatory agents - TCA's
44
What are the indications for surgery in cervical spondylosis?
- Progressive neurological deficits - Documented compression of cervical nerve root, spinal cord, or both - Intractable pain
45
What does the surgical option for cervical spondylosis depend upon?
The precise pathology
46
How can cervical spondylosis surgery be classified?
- Anterior approach | - Posterior approach
47
When is an anterior approach to cervical spondylosis surgery indicated?
When the pathology extends in front of the root and cord
48
What anterior approach surgeries are available for cervical spondylosis?
- Simple discectomy - Cloward's procedure - Decompression with plating or synthetic joint insertion
49
What is Cloward's procedure?
Bone grafting into disc space
50
When is a posterior approach to cervical spondylosis surgery used?
When there is lateral cord narrowing
51
What are the posterior approach procedures available for cervical spondylosis?
- Foraminectomy | - Laminectomy +/- laminoplasty
52
What are the potential complications of cervical spondylosis surgery?
- Spinal cord injury - Nerve root injury - Oesophageal perforation - Recurrent laryngeal nerve palsy (with anterior approach)
53
What are the potential complications of cervical spondylosis?
- Cervical myelopathy - Paraplegia and tetraplegia - Recurrent chest infection - Pressure sores
