Answer 10

Question 11

The preferred instrument for equine arthroscopy is:

• 2.2mm straight head view needlescope
• 4mm 0 degree arthroscope
• 4mm 30 degree arthroscope
• 8mm 25 degree arthroscope
• 1cm 30 degree arthroscope

Answer 11

4mm 30 degree arthroscope​

Question 12

During arthroscopy the egress canula may be used for

• Clearing the joint of debris
• Palpating the chip on examination
• Sampling proliferative synovial membrane
• A and B
• B and C

Answer 12

Clearing the joint of debris​

Question 13

For joint distension with arthroscopy, fluid has the following advantage over gas

• It lavages the joints
• Visual acuity is superior
• Superficial fibrocartilage is easily seen
• A and B
• A and C

Answer 13

It lavages the joints​

Question 14

A number of factors facilitate superior recognition of cartilage lesions with arthroscopy rather than arthrostomy. Which of the following is not one of those factors?

• Magnification
• Transillumination
• Palpation
• None of the above

Answer 14

palpation​

Question 15

In operating on carpal chip fractures arthroscopically

• Only chips 8 mm or smaller can be removed
• Chronic chips are removed with a biopsy-cutting forceps with no restriction on size
• Chronic chips are separated off with an elevator or osteotome and removed
• Chronic chips need to be removed by arthrotomy because of the chronic adhesion

Answer 15

Chronic chips are separated off with an elevator or osteotome and removed

Question 16

For a chip fracture of the proximal aspect of the first phalanx (medial aspect) the arthroscope is placed

• Lateral to the common digital extensor tendon
• Medial to the common digital extensor tendon
• Through the common digital extensor tendon
• Through the volar pouch
• Through the long digital extensor tendon

Answer 16

Lateral to the common digital extensor tendon

Question 17

Chip fractures of the carpus occur most commonly on the __________ bone

Answer 17

distal radial carpal bone​

Question 18

What is the most common indication for arthroscopy?

Answer 18

chip fragment of the carpus

Question 19

What do you observe with regard to the cartilage in this joint?

Answer 19

full-thickness cartilage loss

cartilage is undermined; defect is down to subchondral bone (where nerve endings are)​

Question 20

What do you observe with regard to the cartilage in this joint?

Answer 20

fibrillation

first sign of something wrong; cartilage gets fuzzy appearance; hairy spots are individual fibers coming out​
