Identify this piece of equipment:
exploring probe
Identify this piece of equipment:
egress cannula
What do you observe in the synovial capsule of this joint?
thickened villi
club-like villi; this is a sign of chronicity
What do you observe in the synovial capsule of this joint?
hyperemia
Identify the radial carpal bone in this equine carpus:
Identify the accessory carpal bone in this equine carpus:
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
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
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
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
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
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
Chip fractures of the carpus occur most commonly on the __________ bone
distal radial carpal bone
What is the most common indication for arthroscopy?
chip fragment of the carpus
What do you observe with regard to the cartilage in this joint?
full-thickness cartilage loss
cartilage is undermined; defect is down to subchondral bone (where nerve endings are)
What do you observe with regard to the cartilage in this joint?
fibrillation
first sign of something wrong; cartilage gets fuzzy appearance; hairy spots are individual fibers coming out
