Flashcards in Quiz 2 Ortho Deck (28):
1

What are the functions of the spine?

- provide support and structure to head and extremities
- stabilize the body for function and movement
- protect spinal cord

2

Vertebral bodies

excluding atlas and axis, attach to each other via symphyses

3

Processes

provide sites for attachments of ligaments na muscles
- transverse: lateral
- spinous: posterior

4

Foramen

opening formed by notches

5

What is the function of the Intervertebral Disc?

- shock absorbers
- prevent rubbing

6

What happens to your spine when your in a posterior tilt?

flattened or reversed lumbar curve

7

Lordosis

exaggerated anterior pelvic tilt affects lumbar curve

8

Kyphosis

exaggeration of thoracic curve (hunched back)

9

Scoliosis

curvature of the spine in coronal/frontal plane

10

Degenerative disc disease

- aging and damaged discs (water content decreased); cannot cushion well
- occurs most in cervical and lumbar regions

11

What are the causes of Degenerative disc Disease?

- injury/trauma
- natural loss of blood supply
- cig smoking
- occupational (heavy lifting)
- genetics

12

What is spinal stenosis? What is it caused by?

- narrowing of spinal canal
- caused by: bulging or herniated discs; overgrowth of bone

13

What are the results/symptoms of spinal stenosis?

- may irritate or compress spinal cord or nerve roots (usually cervical or lumbar)
- can cause pain, numbness, weakness in legs, buttocks, arms and neck (dep. on location)

14

What is the difference between a disc herniation and bulge?

- herniation: "not contained" tear or rupture
- bulge: "contained" protrusion into the spinal canal

15

spine spondylolisthesis

anterior sliding of one vertebra over another (most common in the lumbar region)

16

what are the symptoms of spine spondylolisthesis

back or butt pain; radiating pain, numbness/weakness, difficulty walking, increased pain when bending or twisting, loss of bowel or bladder control

17

What is the difference between stable and unstable vertebral fractures?

- stable: don't cause spinal deformity or neurologic problems; still able to function
- unstable: can progress further, may cause deformity, cannot carry/distribute weight

18

laminectomy

lamina is removed

19

diskectomy

removal of herniated disc pressing on nerve root; put in a spacer

20

spinal fusion

eliminates unwanted movement caused by instability of the vertebrae

21

What are the classifications of pelvis fractures?

- Stable: one breakpoint in pelvic ring; min hemorrhage, pelvis in place
- Unstable: 2+ breakpoints, mod hemorrhage, pelvis unstable
- Open: open skin wound
- Closed: no open skin would

22

Non-weight Bearing (NWB)

no weight on affected leg

23

Toe-touch Weight Bearing (TTWB)

touch the floor only for balance on your affected leg

24

Partial Weight Bearing (PWB)

when you walk or stand you may place 30 - 50% of your body weight on your affected leg

25

Weight bearing as tolerated (WBAT)

when walking or standing place as much weight as feels comfortable on affected leg

26

full weight bearing (FWB)

you may place your full body weight on your affected leg when you stand or walk

27

What are the rotator cuff muscles?

Supraspinatus
Infraspinatus
Teres Minor
Subscapularis

28

Gout + Caused by?

- inflammatory type of arthritis; affects synovial capsule of joints
- usually idiopathic
- certain risk factors
