2

What is dacryocystorhinography​?

Radiographic contrast evaluation of the nasolacrimal duct

3

What are the treatment options for compressive spinal cord lesions?

  • Rest
  • Dorsal laminectomy
  • Cervical ventral interbody fusion

4

When using a distraction screw, one turn (360˚) is equal to how much distraction?

Q image thumb

1 mm

It is safe to stretch the bone 1mm/day. If you stretch more than that, you run the risk of creating a false joint

5

What is a clinically relevant compressive lesion on a myelogram?

Both dorsal and ventral columns narrow at the same level​

6

What are the causes of static compressive spinal cord lesions?

Caudal cervical vertebral DJD

  • Degenerative joint disease (DJD) of diarthrodial articulations of caudal cervical vertibrae
  • Diagnosed by myelography: Clinically relevant compressive lesion if both dorsal and ventral contrast columns narrow at same level

7

How is the animal positioned for a laminectomy?

Lateral recumbency, Hanging over the surgery table

8

The most common cause for head and neck fractures in large animals is:

trauma

9

When is it appropriate to use conservative treatment for incisive fractures?

Young foals

10

What is the most common treatment for incisive fractures?

Q image thumb

Cerclage fixation

Other options include conservative treatment, screws, plates, external fixation

11

Pooling of blood inside the anterior chamber of the eye is termed:

hyphema

Indicative of head trauma but not conclusive

12

What are the strongest to weakest methods for repairing mandibular fractures?

  • Strongest: bone plate
  • Weakest: external fixator

13

How do you repair a skull bone depression?

Elevate with a periosteal elevator, secure with cerclage wire​

14

If you do find blood in the sinuses, how do you drain it?

Q image thumb

Place a foley catheter and secure

15

In patients with suspected head trauma and increased intracranial pressure, the use of __________ is contraindicated

ketamine

16

What portion of the neck should tracheostomy tubes be placed?

Upper 1/3 of the neck on midline

17

Identify this condition. How is it repaired?

Q image thumb

Parrot Mouth

This is when the front edge of the top incisors is further forward that that of the lower teeth. This is repaired by osteotomy followed by external fixator with distraction screw.

18

T/F: Non-displaced fractures of the vertical ramus require surgery

Q image thumb

False

The masseter muscle stabilizes the fracture

19

How do horses typically develop basilar fractures?

Q image thumb

horse flips over backwards

20

What do you need to warn the client about before performing a myelogram?

may increase spinal cord deficits

21

How is the animal positioned for a cervical ventral interbody fusion?

Dorsal recumbency, "over stretching" neck

22

What are the causes for neck vertebrae fractures?

Q image thumb

Trauma and electrocution (struck by lightning)

23

What is veisalgia?

a hangover.

Not relevant to Large Animal Surgery, but still interesting.

24

You're preparing a horse for fracture fixation and decide to administer rocuronium. You quickly realize this was a stupid idea. What agent can be used to reverse your mistake?

Sugammadex

Happy finals week, suckas!
