Q

Spondylosis

A

2ndary degenerative changes including disc degeneration, dessication, height loss, herniation, joint degredation, ligamentous thickening and infolding, as well as deformity such as kyphosis, common finding in many by age of 40-60, typically episodic, exacerbated with extension, sees occipital headaches (cervicogenic pattern)

Q

Shoulder abduction test

A

Shoulder abduction bringing relief of cervical radiculopathy symptoms

20
Q

Cervical myelopathy presentation (3)

A
  • subtle clumsiness of hands and gait imbalance in early manifestations
  • dropping things, inability to manipulate small objects
  • physical weakness upper extremity early and lower extremity late stage (either severe or coexistent lumbar stenosis)
21
Q

Cervical myelopathy definition

A

Caused by spinal CORD compression rather than a specific nerve root from wear and tear of aging

22
Q

Cervical myelopathy causes (5)

A
  • ossification of posterior longitudinal ligament
  • congenital stenosis
  • tumor/abscess
  • spondylosis
  • trauma
23
Q

Lhermitte’s sign

A

Electric shock like sensations down spine or legs with certain positions of the neck, indicating MS, cervical spondylosis, cervical disk herniation, etc

24
Q

Finger escape sign

A

Test for cervical myelopathy where when asked to hold fingers extended and adducted the small finger abducts spontaneously due to weak intrinsics

25
Q

Grip/release test

A

Test for cervical myelopathy asking patients to make fist 20 times in 10 seconds, if fail then positive for cervical myelopathy

26
Q

Babinski reflex

A

Test used sometimes for cervical myelopathy that should be positive in new borns but negative in those 2 and older where when the sole is stimulated the toes fan out if positive

27
Q

Hoffmans sign

A

Test used for cervical myelopathy where involuntary flexion of index and or thumb occurs when snapping the middle finger distal phalanx downward

28
Q

Cervical myelopathy treatment options (3)

A
  • stop progression, not improve symptoms, damage is often irreversible
  • mild dz NSAIDS with frequent follow up needed
  • surgery for severe progressive symptoms
29
Q

Ossification of the posterior longitudinal ligament is most commonly seen in what population?

A

Asian

30
Q

Causes of low back pain (5)

90% resolves in __

A
  • muscle/lig strain
  • facet joint arhtropathy
  • annular tears or discogenic pain
  • spinal stenosis
  • spondylolithesis

-1 year

31
Q

Waddell signs

A

Signs of nonorganic (kinda sorta faking it) back pain, clinically significant if 3 positive signs are present

  • superficial and nonanatomic tenderness
  • pain with axial compression or simulated rotation
  • negative straight leg raise while patient is distracted
  • nondermatomal regional pain pattern
  • overreaction on physical exam
32
Q

When is x ray indicated for lower back pain?

A

->6 weeks or when red flags are present

33
Q

Low back pain treatment options (3)

A
  • NSAIDS
  • PT
  • surgical fusion
34
Q

Lumbar disc herniation is more common in what gender? What is the most common level? What happens over time with most?

A

Men, L5-S1>L4-5, Macrophages reabsorb and diminish size over time

35
Q

How would you test for an L1-3 radiculopathy? (sensory and motor and reflex)

A
  • Hip to groin and inner thigh
  • Hip flexion
  • No reflex
36
Q

How would you test for L4 radiculopathy? (sensory and motor and reflex)

A
  • anterior thigh going down to front of knee
  • Knee extension/foot dorsiflexion
  • patellar reflex
37
Q

How would you test for L5 radiculopathy? (sensory and motor and reflex)

A
  • anterior shin going down to the toes

  • trendelenberg gait
38
Q

How would you test for S1 radiculopathy? (sensory and motor and reflex)

A
  • outer shin down to the pinky toe
  • Foot planterflexion/eversion
  • achilles reflex
39
Q

Types of lumbar disk herniation

A
  • Protrusion/prolapse (bulging thru intact annulus)
  • Extrusion (disk material crosses annulus and is projecting out)
  • Sequestered (free fragment of nucleus pulposis)
40
Q

Posteriolateral L4-5 Disc herniation affects what nerve root?

A

L5 nerve root

41
Q

Far lateral L4-5 Disc herniation affects what nerve root?

A

L4 nerve root

42
Q

Lumbar disc herniation treatment options (2)

A
  • NSAIDS and PT
  • Partial discectomy surgery within 3-4 months if not resolving, absolutely indicated in cauda equina or progressive neurologic deficit
43
Q

Lumbar spinal stenosis cause

A

Not understood, congenital, acquired, both

44
Q

Lumbar spinal stenosis symptoms (3)

A
  • leaning forward alleviates symptoms
  • Extension of spine decreases space worsening symptoms
  • pain, paresthesias, subjective weakness or heaviness in back, buttock, and lower extremities
45
Q

Lumbar spinal stenosis treatment options (3)

A
  • NSAIDS and PT
  • Gabapentin for nerve pain
  • Surgery such as laminectomy
46
Q

A

L4-5>L5S1

47
