GF19: Neuro Spinal Stenosis Flashcards

1
Q

What is Spinal Stenosis?

A
  • Spinal stenosis is the narrowing of one or more spaces within your spine.
  • Less space within your spine reduces the amount of space available for your spinal cord and nerves that branch off your spinal cord.
  • A tightened space can cause the spinal cord or nerves to become irritated, compressed or pinched, which can lead to back pain and sciatica.

Q

What are some causes of spinal stenosis?

A
  • Overgrowth of bone
    • Bone spurs: can grow into spinal canal
    • Paget’s disease: a bone overgrowth disease that can intrude on spinal canal
  • Herniated disks
  • Thickened ligaments
    • The tough cords that help hold the bones of the spine together can become stiff and thickened over time
    • These thickened ligaments can bulge into the spinal canal
  • Tumors
  • Spinal injuries
  • Osteoarthritis and Rheumatoid arthritis
  • Birth defects

Q

What will X-rays show related to spinal stenosis?

A

Q

How does applying heat help relieve spinal stenosis s/s?

A

Heat increases blood flow, which relaxes muscles and relieves aching joints.

Q

How does applying cold help relieve spinal stenosis s/s?

A
  • If heat therapy doesn’t work, cold therapy can be attempted
  • Typically ice is applied 20 minutes on and 20 minutes off.
  • Ice reduces swelling, tenderness and inflammation.

Q

How does applying exercise help relieve spinal stenosis s/s?

A

Exercise is helpful in relieving pain, strengthening muscles to support your spine and improving your flexibility and balance.

17
Q

What medications are used to help manage spinal stenosis s/s?

A
  • NSAIDs: relieve pain and inflammation
    • ibuprofen (Advil®, Motrin®), naproxen (Aleve®), aspirin – or acetaminophen (Tylenol®)
    • Risk: acid reflux and stomach ulcers are sfx
  • anti-seizure drug
    • gabapentin (Neurontin®) or
  • tricyclic antidepressants such as
    • amitriptyline (Elavil®).
  • Opioids, such as
    • oxycodone (Oxycontin®) or
    • hydrocodone (Vicodin®)
18
Q

When should a pt w/ spinal stenosis consider surgical options?

A
  • Your symptoms are intolerable, you no longer have the quality of life you desire and you can’t do or enjoy everyday life activities.
  • Your pain is caused by pressure on the spinal cord.
  • Walking and maintaining your balance has become difficult.
  • You have lost bowel or bladder control or have sexual function problems
19
Q

What are the surgical options for spinal stenosis?

A
  • Laminectomy
  • Laminotomy
  • Laminoplasty
  • Foraminotomy
  • Spinal Fusion
20
Q

Describe Laminectomy.

A
  • Aka: decompression surgery
  • Most common surgery for spinal stenosis
  • involves removing the lamina, which is a portion of the vertebra. Some ligaments and bone spurs may also be removed.
  • The procedure makes room for the spinal cord and nerves, relieving your symptoms.
21
Q

Describe Laminotomy.

A
  • This is a partial laminectomy.
  • In this procedure, only a small part of the lamina is removed – the area causing the most pressure on the nerve.
22
Q

Describe Laminoplasty.

A

In this procedure, performed in the neck (cervical) area only, part of the lamina is removed to provide more canal space and metal plates and screws create a hinged bridge across the area where bone was removed

23
Q

Describe Foraminotomy

A
  • The foramen is the area in the vertebrae where the nerve roots exit.
  • The procedure involves removing bone or tissue this area to provide more space for the nerve roots.
24
Q

Describe spinal fusion:

A
  • Spinal fusion surgery permanently joins (fuses) two vertebrae together.
  • A laminectomy is usually performed first and bone removed during this procedure is used to create a bridge between two vertebrae, which stimulates new bone growth.
  • The vertebrae are held together with screws, rods, hooks or wires until the vertebrae heal and grow together. The healing process takes six months to one year.
