Q

what are upper motor neuron signs that should prompt further assessment in back pain?

A
  • Hyperreflexia = exaggerated reflexes
  • Spasticity= increased muscle tone leading to stiffness
  • Positive Babinski sign = big toe extends upwards when sole foot stroked
  • Clonus = involuntary, rhythmic muscle contractions following a sudden stretch of muscle (hit tendon with hammer)

*remember that upper motor neurons = nerves that control motor function

Q

what is spinal osteomyelitis?

A

infection of the vertebrae, typically caused by bacteria (most commonly Staphylococcus aureus), though fungal infections can also be a cause. This condition can result in the destruction of vertebral bone tissue and, if left untreated, may lead to severe complications such as spinal abscesses, vertebral collapse, or even spinal cord compression.

Q

what are 3 types of spinal deformity? (common ones)

A
  1. scoliosis
  2. kyphosis
  3. spondylolisthesis
23
Q

what is scoliosis?

A

spinal deformity with sideways or coronal curve. also associated with vertebral rotation

24
Q

what are ways scoliosis may present?

A
  • may be able to visibly see
  • pain (not common feature of scoliosis)
  • sideways listing
  • prominent rib hump
  • asymmetry of shoulders (1 shoulder lower than the other)
25
Q

what are causes of scoliosis?

A
  • idiopathic
  • congenital
  • neuromuscular disease (associated with CP etc)
  • unequal leg length (can cause scoliosis)
  • degeneration
  • connective tissue disease
  • spinal tumour
  • spinal pain
26
Q

what are age classifications of scoliosis?

A
  • congenital
  • juvenile
  • adoloscent idiopathic scoliosis (10-18yrs)
  • adult onset
27
Q

what is involved in assessment of scoliosis?

A
  1. detailed history
  2. MSK spine exam and UL + LL neurological exam
  3. test = bend forward to look for rib hump (Adams test)
  4. refer to spinal deformity service
  5. whole spine X-ray (AP and lateral)
  6. may need MRI if atypical features
28
Q

what is the management of scoliosis?

A

→depends on skeletal maturity, severity of deformity & progression of deformity

  • observation
  • bracing
  • operation (usually avoided for children who are not finished growth)
29
Q

what is kyphosis?

A

spinal deformity with excessive convex curvature of spine, involving thoracic spine (commonly see stoop when walking)

30
Q

how does kyphosis present?

A
  • it’s a sagittal deformity, seen from inspecting patient from side

*note = thoracic spine is naturally kyphosed. kyphosis means hyper/excessive kyphosis

31
Q

what are causes of kyphosis?

A

Scheuermann’s disease (developmental disorder) , osteoporosis with wedge fractures (like squashes down vertebrae at front to curve spine)

32
Q

what is spondylolisthesis?

A

spondylos = spine or vertebra
listhesis = slip

  • it’s anterior subluxation one vertebra on another (another sagittal spinal deformity)
33
Q

what are classifications of spondylolisthesis based on?

A

can be based on aetiologies or degree of slip (meyerding grading)

34
Q

what is management of spondylolisthesis? (if not too severe)

A

usually manage limb symptoms like treat leg pain with decompression and fusion

35
Q

what are 2 main types of cervical spine problems?

A
  1. cervical radiculopathy
  2. cervical myelopathy
36
Q

what is cervical radiculopathy?

A

radiculopathy = nerve being pinched at root

so in this case in cervical region

37
Q

how would cervical radiculopathy present?

A
  • pain radiating from neck down into arm
  • numbness and/or weakness in upper extremities
38
Q

what are causes of cervical radiculopathy?

A
  1. cerebral disc prolapse
  2. vertebral osteophytes (bony lumps)
  3. other compressive lesions like tumours
39
Q

what are nerve root syndromes (types of cervical radiculopathy?)

A
  1. C5 from C4/5 disc. rare. pain radiates to shoulder. biceps reflex
  2. C6 from C5/6 disc. 20%. Pain radiates to thumb, lateral forearm. Brachioradialis reflex
  3. C7 from C6/7 disc. 70%. Pain radiates to fingers 2&3. Triceps reflex
  4. C8 from C7T1 disc. 10%. Pain radiates to fingers 4&5. Finger reflex
40
Q

what is cervical myelopathy?

A

myelopathy →inflammation/arthritis etc causing compression of spinal cord

so at cervical region

41
Q

how does cervical myelopathy present?

A
  • history of slow progressive symptoms like clumsiness of hands & feet, mild gait disturbance, paraesthesia of upper&lower extremities
  • later symptoms of loss of coordination, changes in gait & stiffness
  • change in bowel & bladder function

*makes sense that starts slow as something progressively growing & constricting

42
Q

what are causes of cervical myelopathy?

A
  • often associated with compression from inflammation & arthritis but other common causes:
  1. disc osteophyte complex
  2. ligamentous hypertrophy
  3. degenerative spondylolisthesis
  4. other compressive lesions like tumours
43
Q

what can cause lumbar disc herniation, lumbar stenosis and spondylolisthesis, and degenerative scoliosis?
hint = 3 parts that can have problems and in combination lead to above

A
  1. disc - disc desiccation, annular tears, disc bulge, disc prolapse, disc fibrosis & resorption
  2. facet joint - hypertrophy, effusions & laxity
  3. ligamentum flavum hypertrophy
44
Q

what is lumbar disc herniation?

A

= when a soft cushion of tissue between the bones in your spine bulges outwards (slipped disc)

= can be asymptomatic

45
Q

what can lumbar disc herniation cause?

A
  1. lumbar radiculopathy
  2. cauda equina (dysfunction of multiple lumbar & sacral nerve roots)
46
Q

how does lumbar radiculopathy present?

A

pain radiating into leg. numbness & weakness. pain constant. worse with WB, valsalva & SLR

47
Q

how does cauda equina present?

A

urinary retention, urinary & faecal incontinence, saddle anaesthesia. lumbar radiculopathy features also seen a lot

48
Q

what is saddle anaesthesia?

A

a loss of sensation in the buttocks, perineum, and inner thighs

49
Q

what are types of lumbar stenosis?

A
  1. central stenosis = compression of all nerve roots passing through
  2. lateral recess stenosis = compression of transiting nerve root
  3. foraminal stenosis = compression of exiting nerve root
50
Q

what causes lumbar stenosis?

A

facet & ligament hypertrophy, additional spondylolisthesis in some

51
Q

how does lumbar stenosis present?

A

stenosis tends to present with claudicant leg pain, worse when walking/prolonged standing. relieved upon flexion of spine

52
Q

how would you assess back pain in physical exam?

A

Look = how patient walks in & out, deformity

Feel = spinal tenderness, paravertebral muscles, get patient to show where

Move = flexion, extension, lateral flexion →SLR, tone, power, reflexes, sensation in legs

53
Q

what is TUNA FISH mnemonic for red flags of back pain?

A

T = trauma

U = unexplained weight loss

N = neurological symptoms

A = age >50

F = fever, feeling unwell

I = immunocompromise (e.g. HIV)

S = steroids (for prolonged time)

H = history of carcinoma (breast, bronchus, prostate)
