GF19: Neuro Spinal Stenosis Flashcards
What is Spinal Stenosis?
- 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.
What are some causes of spinal stenosis?
- 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
What are the general s/s of spinal stenosis?
- Standing discomfort
- Discomfort/pain in shoulder, arm, hand
- Bilateral symptoms
- Numbness/paresthesia at or below the level of involvement
- Pain/weakness in buttock/thigh only
- Pain/weakness below knee
Spinal stenosis usually develops slowly over time. It is most commonly caused by _____ or _____ changes that naturally occur in your spine as you age.
- Osteoarthritis
- “wear-and-tear”
Depending on where and how severe the spinal stenosis is, the pt might feel
pain, numbing, tingling and/or weakness in the neck, back, arms, legs, hands or feet.
Spinal stenosis can occur anywhere along the spine but most commonly occurs in two areas:
- Lower back (lumbar canal stenosis).
- Neck (cervical spinal stenosis).
Symptoms of lumbar canal stenosis include pain, numbness or weakness in the legs, groin, hips, buttocks, and lower back. Symptoms usually worsen when _____ or _____ and might decrease when _____, _____, or _____.
- walking or standing
- lying down, sitting, or leaning slightly forward
Spinal stenosis can develop in anyone but is most common in men and women over the age of __.
50
What dx tests are run for spinal stenosis?
- X-rays
- MRI
- CT
What will X-rays show related to spinal stenosis?
Changes in bone structure, such as loss of disk height and development of bone spurs that are narrowing the space in the spine
What will an MRI show related to spinal stenosis?
Detailed images of the nerves, disks, spinal cord and presence of any tumors.
What treatments are available for spinal stenosis?
- For mild s/s:
- Self-care remedies
- For stronger s/s:
- PT
- Medication
- Surgery (if all else fails)
What are the self-help tx for spinal stenosis s/s?
- Apply heat
- Apply cold
- Exercise
How does applying heat help relieve spinal stenosis s/s?
Heat increases blood flow, which relaxes muscles and relieves aching joints.
How does applying cold help relieve spinal stenosis s/s?
- 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.
