How would you manage a less severe lower cervical subluxation?

A

Conservative - analgesia, physio

35
Q

A

Consider stabilisation/fusion

Q

Describe the management of cauda equina syndrome

A

Urgent discectomy

39
Q

A

Unilateral leg pain that is greater than the back pain, sharp, shooting electric pain, pain radiates to foot, numbness and parasthesia in the same distribution

40
Q

Why is new back pain in an older patient (> 60 years) considered a red flag?

A

Higher risk of neoplasia - particularly metastatic disease and multiple myeloma

41
Q

If the C6/7 IV disc prolapses, which nerve root is more likely to be involved?

A

C7

42
Q

What is the most common causative organism for vertebral osteomyelitis?

A

Staph. aureus

43
Q

Describe the management of bony nerve root entrapment

A

Surgical decompression, with trimming of the impinging osteophytes, may be performed in suitable candidates

44
Q

Which nerve root is most commonly compressed in sciatica?

A

L5/S1

45
Q

Describe the clinical presentation of spinal stenosis

A

Pain in the legs on walking (claudication), pain is burning in nature

46
Q

What is bony nerve root entrapment?

A

OA of the facet joints can result in osteophytes impinging on exiting nerve roots, resulting in nerve root symptoms and sciatica

47
Q

Describe the surgical management of vertebral osteomyelitis

A

Debridement, stabilization and fusion of adjacent vertebrae

48
Q

Describe the conservative management of spinal stenosis

A

Analgesia, physiotherapy, weight loss if indicated

49
Q

What is an acute disc tear?

A

Acute tear in the outer fibrosis of an IV disc which classically happens after lifting a heavy object (e.g. lawnmover)

50
Q

What cardiac condition can cause vertebral osteomyelitis?

A

Endocarditis

51
Q

What is vertebral osteomyelitis?

A

Infection of the vertebrae

52
Q

How would you investigate vertebral TB?

A

X-ray, MRI

Check for immunosuppression/HIV

53
Q

What is spinal stenosis?

A

Narrowing of the central spinal canal, IV foramen and/or lateral recess causing progressive nerve root compression

54
Q

What causes sciatica?

A

Compression of a nerve root, most commonly L5/S1

Usually due to prolapse of a disc which impinges on the nerve root

55
Q

What is mechanical back pain?

A

Recurrent relapsing and remitting back pain with no neurological symptoms

56
Q

What examination would you perform in suspected cauda equina syndrome and what would you expect to see?

A

PR exam - loss of anal sphincter tone

57
Q

How can rheumatoid arthritis cause atlanto-axial subluxation?

A

Destruction of the synovial joint between the atlas and the dens and rupture of the transverse ligament

58
Q

What is sciatica?

A

Characteristic pain felt in the lower back, buttocks and the posterior and lower leg that results from compression of any of the 5 nerve roots that contribute to the sciatic nerves

59
Q

Describe the surgical management of spinal stenosis

A

Decompression to increase space for the cauda equina

60
Q

Why is constant, severe back pain worse at night considered a red flag?

A

Suggests tumour or infection rather than mechanical cause

61
Q

Describe the clinical presentation of a cervical disc prolapse

A

Shooting neuralgic pain down a dermatomal distribution with weakness and loss of reflexes depending on the nerve root affected

A large central prolapse can compress the cord leading to a myelopathy with upper motor neurone symptoms and signs

62
Q

Describe the normal management of sciatica

A

90% resolve spontaneously within 3 months - advise NSAIDs and analgesia

63
Q

Describe the clinical presentation of cervical spondylosis

A

Slow onset stiffness and pain in the neck, pain can radiate to shoulders and occiput

64
Q

Name the indications for surgery in vertebral osteomyelitis

A

Inability to obtain cultures by needle biopsy, no response to antibiotic therapy, progressive vertebral collapse and progressive neurological deficit

65
Q

What is cauda equina syndrome?

A

A very large central disc prolapse compresses all the nerve roots of the cauda equina

66
Q

What is Pott disease?

A

Vertebral body osteomyelitis and intervertebral discitis from tuberculosis (TB)

67
Q

Describe osteophytes as a complication of cervical spondylosis

A

Osteophytes can impinge on the exiting nerve roots resulting in a radiculopathy involving the upper limb dermatomes and myotomes - may require surgical decompression

68
Q

What causes cervical spondylosis?

A

As with the rest of the spine, spondylosis can occur with disc degeneration leading to increased loading and accelerated OA of the facet joints

69
Q

Why is back pain from an acute disc tear severe?

A

The periphery of the disc is richly innervated

70
Q

Why is back pain with associated systemic upset (fever, night sweats, weight loss etc.) considered a red flag?

A

May suggest underlying tumour or infection

71
Q

What causes spinal stenosis?

A

Mainly caused by degenerative joint disease in middle aged to elderly individuals - spondylosis, bulging discs, bulging ligamentum flavum and osteophytosis

72
Q

Why is cauda equina syndrome a surgical emergency?

A

Prolonged compression can cause permanent nerve damage requiring colostomy and urinary diversion

73
Q

What is the most common route of spread for vertebral osteomyelitis?

A

Haematogenous

74
Q

Why is back pain in a younger patient (> 20 years) considered a red flag?

A

Children - more susceptible to infections e.g. osteomyelitis
