to show transverse foramen

Question 7

Want angulation is used of a ant and post cervical oblique

Answer 7

ant= 15 caudad
post = 15 cephalad

Answer 11

accel/decell
axial loading
degenerative

Question 12

What do the 4 spinee lines demark?

Answer 12

Ant vert body
Post vert body
SPinal Canal
spinous process

Question 13

WHat is the first action taken with a semi-concious patient?

Answer 13

GCS test

Question 14

What is an Os odontoideum

Answer 14

NAtural varience in odontiond process.

-will have smooth border

Question 15

Name the 7 cervical # pathos

Answer 15

hangmans
JEffersons
Clay-shovellers
Teardrop
wedge
Burst
Odontoid

Question 16

Hangmans # details

Answer 16

Distraction and extension (head is snapped upwards and backwards into hyper extension)

Vertical/oblique # to C2 @ pedicles = UNSTABLE

Traumatic spondylosis.

Question 17

Jeffersons # details

Answer 17

best seen on lat and PEG

Axial load to top of head (DIVING HEAD FIRST INTO WATER) Jefferson Airplane

typically quadrapartite to C1 - RING THEORY

loose fragments may move into spinal cord.

Question 18

Clay shovellers # details

Answer 18

Accel -> deaccel, flexion -> extension. EG Slamming breaks on in car

Avulsion # commonly at C&

Use lat +/- swimmers

Question 19

Teardrop #

Answer 19

axial load + small flex/ext

TYPICALLY flexion causes inf vert body # @ C5-C6

CAN RUPTURE ANT LONGITUDINAL LIGAMENT, this ligament is important for stabilising the spine anter-posteriorly.

Vertvrae fragment can be moved backwards into spinal canal (retropulsion) very serious.

Question 20

Wedge # details

Answer 20

typically seen on lat

AXIAL compression - tup down/ bottom up

Comminuted # to CTL vertebrae

typically anterior portion of V body becomes wedge shaped.

Question 21

Burst #

Answer 21

Wedge fracture with retropulsion of bone fragments.

Question 22

burst v wedge #

Answer 22

Burst is wedge with retropulsion

Question 23

Odontoid #

Answer 23

Flexion and extension , msot commonly with a shearing force element.

Question 24

what type of odontoid fracture is most common?

Answer 24

type 2

Question 25

Zygopophyseal joint dislocation

Answer 25

distraction + anterior force PERCHED facet joint - inf and sup processes lock into place. halo traction needed for cervical region. less common in T and L.
