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

4mm 30 degree arthroscope​

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

Clearing the joint of debris​

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

It lavages the joints​

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

palpation​

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

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

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

Lateral to the common digital extensor tendon

17

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

distal radial carpal bone​

18

What is the most common indication for arthroscopy?

chip fragment of the carpus

19

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

Q image thumb

full-thickness cartilage loss

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

20

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

Q image thumb

fibrillation

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