Thoracic Spine X-Rays Flashcards
1
Q
Costotransverse Joint
A
- Ribs form a joint at most levels with transverse processes
2
Q
Intervertebral Foramen
A
- Anterior boundary: vertebral bodies and discs
- Posterior boundary: facet joints (articular processes of two adjacent vertebrae)
- Superior boundary: pedicle of vertebrae above
- Inferior boundary: pedicle located below
3
Q
Content of Intervertebral Foramen
A
- Primarily the spinal nerve, blood vessels, and recurrent meningeal nerve
4
Q
Axial Rotation
A
- Turning side to side
5
Q
Lateral Flexion
A
- Bending side to side
6
Q
Ribs
A
- Limit all thoracic spine movement in some way
7
Q
Compression Fracture
A
- Typically involves vertebral bodies from some type of trauma from falling on your butt
- Most common in mid-lower thoracic and lumbar regions
- Also common in elderly because of osteoporosis
8
Q
Lumbo-Sacral Joint
A
- Inferior articular processes of L5 articulate with superior articular process of sacrum
- Located between L5 and sacrum
9
Q
Sacroiliac Joint
A
- Between sacrum and hip bone
- Both fibrous and synovial joint
- Portion is fibrous with connective tissue, other portion with synovial capsule
10
Q
Scotty Dog
A
- Nose = trans process
- SAP = ear
- Pedicle = eye
- IAP = front leg
- Lamina and spinous process = body
- SAP of opposite side = tail
- IAP of opposite side = hind legs
- Neck = pars interarticularis
11
Q
Spondylolisthesis
A
- Anterior slippage of L5 on sacrum
12
Q
Sponylolysis
A
- Fracture in lumbar spine or pars interarticularis
- More common in L4 and L5
13
Q
Pars Interarticularis
A
- In lumbar spine
- Part of the lamina between articular processes (SAP and IAP)
14
Q
Lumbarization of S1
A
- First sacral segment can fuse/form differently to become completely or partially part of lumbar vertebrae
- Looks like you have 6 lumbar
15
Q
Transitional Segments
A
- Evidence points to some (depending on classification and how it forms) can be associated with low back pain
