End plates parallel; pedicles superimposed

Question 4

OR etiquette

Answer 4

OR control
1 step ahead
Rapport w OR staff
Maintains sterility

Question 5

Transpediculater vs extrapediculater

Answer 5

Trans: thick pedicles
Extra: thin pedicles

Question 6

How to explain via extrapediculater

Answer 6

Avoiding costovertebral joint; go medial

Question 7

Characteristics between Trans and extrapedicular

Answer 7

T5-T10 extrapedicular: around the pedicle; laterally oriented (one step ahead in lateral

T10-L5 transpedicular: through the pedicle; medially oriented (steps align)

Question 8

Best type of image for kypho? Why?
