Lecture 20: SA Arthroscopy (Exam 3) Flashcards
Uses of arthroscopy
- diagnosis of joint

- conditions involving cartilage and ligaments
what are the Advantages of arthroscopy minimally invasive(less tissue damage
- minimally invasive (less tissue damage)
- less painful
- faster recovery
- treat multiple joints together
- sometimes can be faster
- visualization in joint better (light source and magnifications)
what are the Disadvantages of arthroscopy
- cost of equipment
- delicacy of equipment
- difficult to learn
What are the 2 reported complications of arthroscopy
- extravasation of fluid (resolves within 24 hours)
- iatrogenic peripheral nerve injury (if portals placed improperly)
What is seen in this image
stryker tower and fluid cart
What is # 1?
outflow (egress)
What is # 2?

The Top 3 are called what? what about the bottom 3
- Top: Obturators
- Bottom: Cannula
What technique is seen here
triangulation technique
what 3 ports are for arthroscopy
- ingress(camera port)
- egress(outflow)
- treatment portal
Name the arthroscope
- covers 90 degrees sector directly opposite of the light scope
- minimum movement needed
30 degree wide angle arthroscope
What can be txed w/ arthroscopy
- OCD
- bicipital tenosynovitis
- shoulder instability
- glenoid avulsions fractures
- septic arthritis
What structures are you seeing here on shoulder arthroscopy
- normal biceps tendon
- medial glenohumeral ligament
What is wrong
- 8 month old golden retriever
- shifting forelimbs lameness since 3 months of age
- painful bilateral shoulder
Osteochondritis Dissecans (OCD)
When you have the pressure of the arthroscope high what do you see less of
bleeding
What should be @ the top of you DDX list
- 5 yo FS Australian Shep. Mix
- Right forelimb lame for 6 months
- Painful shoulder over biceps tendon area
- US- biceps brachii tendon abnormalities
Biceps brachi tendinopathy
What is wrong
year old female spayed lab retriever presenting for:
* history of L forelimb lameness
* shoulder discomfort
* joint tap WNL
* radiographing mild DJD
* You preform arthorocentsis and find this?
partial tear of medial glenohumeral ligament
