Q

What is the typical age-related prevalence of degenerative disc disease in individuals over 60 years old?

21
Q

What type of pain is usually described in cauda equina syndrome?

A

Shooting or stabbing pain

Pain radiates down the affected lower extremity (LE) past the knee and may have associated neurologic symptoms such as weakness and numbness.

22
Q

What is a common characteristic of patients with cauda equina syndrome?

A

*Bowel or bladder dysfunction
*unilateral or bilateral lower extremity pains
*saddle anesthesia
*decreased anal sphincter tone

23
Q

What physical exam finding increases pain in cauda equina syndrome?

A

Pain increased with coughing, sneezing, or Valsalva maneuver

A positive straight leg raise may also be noted.

24
Q

What is the most common cause of cauda equina syndrome?

A

Large disc herniations

L4-L5 is the most commonly affected level, occurring in 1-6% of lumbar herniated discs.

25
What are the symptoms of cauda equina syndrome?
Unilateral or bilateral LE pains, sensory or motor changes in the LE, bowel or bladder dysfunction ## Footnote Symptoms may include retention leading to overflow incontinence and saddle anesthesia.
26
What is the diagnostic test of choice for cauda equina syndrome?
MRI ## Footnote It is critical to perform emergent surgical decompression within 48 hours.
27
Define scoliosis.
Lateral curvature of the spine ## Footnote Classified based on patient age.
28
What is the most common type of scoliosis?
Adolescent idiopathic scoliosis ## Footnote Incidence is 3% for curves 10-20 degrees and 0.3% for curves >30 degrees.
29
What are the potential causes of scoliosis?
* Idiopathic * Neuromuscular conditions * Connective tissue disorders * Genetic conditions * Asymmetric degenerative changes in adults ## Footnote Pathophysiology remains unclear for many cases.
30
What is a common presentation of scoliosis in children?
Painless deformity or through screening ## Footnote Adults typically present with axial back pain and reduced range of motion.
31
What is the diagnostic imaging test for scoliosis?
Long/entire spine AP x-ray ## Footnote A Cobb angle >10° is diagnostic.
32
How do you calculate the Cobb angle?
Determine the end vertebrae, draw a line parallel to the endplate, and measure the angle at the intersection of the two lines ## Footnote The end vertebrae are those angled most severely towards the concave portion.
33
What is the treatment approach for scoliosis with a Cobb angle of 0-30 degrees in skeletally immature patients?
Observation with serial x-rays ## Footnote Skeletally mature patients with the same curve may require no intervention.
34
At what point are surgical options considered with scoliosis?
Cobb angle greater than 50 degrees or if patient is symptomatic
35
True or False: MRI is necessary for diagnosing scoliosis in all cases.
False ## Footnote MRI is not necessary unless neurological deficits or significant radicular symptoms are present.
36
Who is at greatest risk for ankylosing spondylitis?
Caucasian males around age 30
37
What gene is ankylosing spondylitis associated with?
HLA-B27
38
Schobers test
Physical test used in diagnosing ankylosing spondylitis. Measurements are taken 10 cm above and 5 cm below lumbosacral junction, should expand greater than 15 cm with forward flexion, positive if no expansion
39
How are spinal radiographs typically referenced in patients with ankylosing spondylitis?
Bamboo spine
40
What are the typical treatments for ankylosing spondylitis?
Symptomatic treatment with TNFa inhibitors, if ineffective JAKi inhibitors, surgical treatment for complications
41
Spondylolisthesis
Fracture of pars interarticularis with vertebral shift due to instability
42
What injury is associated with a “Scotty dog” sign on X-ray?
Spondylolysis
43
What site is spondylolisthesis most common?
L4-L5
44
Spinal stenosis
Narrowing of spinal cord, number 1 reason for spine surgery of patients >65 years old
45
What is the diagnostic test of choice for spinal stenosis?
MRI
46
Sciatica
Radiculopathy of sciatic nerve, with most cases secondary to herniated disc
47
Typical symptoms associated with sciatica.
Shooting or stabbing pain, radiates down lower extremity, may have associated weakness, numbness, parenthesis , often cannot get comfortable or tolerate sitting
48
What medications will be prescribed if there is an underlying cause contributing to nerve symptoms of sciatica?
Gabapentin or Pregabalin
49
What disorder requires emergent surgical decompression within 48 hours to prevent permanent lower extremity detriments?
Claudia equina
