What is the role of the anterior vertebral body?

A

Supports weight bearing

5
Q

What is the role of the posterior vertebral arch?

10
Q

What is Cauda Equina Syndrome?

A

Spinal nerve root compression due to massive disc protrusion, fracture/trauma, or a tumor resulting in bowel/bladder dysfunction

11
Q

What causes spina bifida?

A

Congenital malformation normally due to failure of lamina fusion in vertebra leading to neural tube defects in lumbar spine

A

Small split in vertebrae with NO spinal cord protrusion

Normally found at L5-S1

Q

What is a myelomeningocele?

A

Unfused portion of spinal cord protrudes through opening that can cause severe neurologic complications

15
Q

What is Ferguson’s Angle?

A

Angle made with two measurements evaluating the stability of the lumbosacral region

  • Lumbosacral angle
  • Lumbar gravity line
16
Q

What is the normal Ferguson’s Angle?

A

30-40 deg

17
Q

What is a disc herniation?

A

Rupture of the nucleus pulposus causing protrusion of intervertebral disc into spinal canal or externally into facet with potential for encroachment on spinal nerve roots
