Stifle

Question 1

Three projections in the standard stifle series

Answer 1

Lateromedial, Caudocranial, caudolateral – craniomedial oblique

Question 2

What are two additional views that can be taken of the stifle

Answer 2

Cranio 5* disto 10* lateral-caudoproximomedial oblique

Cranioproximal-craniodistal (skyline) of the patella

Question 3

What are three ways to alter radiographic technique when shooting a stifle

Answer 3

Collimate, decrease FFD, increase MAS

Question 4

What are the three compartments of the stifle?
Which two most often communicate?
What is a notable extra-articular structure of the stifle?

Answer 4

Lateral femorotibial, medial femorotibial, femoropatellar

The last two

Cruciate ligament’s

Question 5

Three purposes of the Caudocranial projection of the stifle

Answer 5

Evaluate joint space, femoral condyle’s, intercondylar eminences of the tibia

Question 6

Purpose of caudolateral-craniomedial oblique. What is important about these sites?

Answer 6

Lateral trochlear ridge and medial femoral condyle

Most common sites OCD of stifle

Question 7

DJD of stifle

prognosis

inciting caused

four common radiographic findings

Answer 7

Poor prognosis

Typically secondary to traumatic injury to supporting soft tissues of the stifle (ligaments, menisci), osteochondrosis, fractures or sepsis

Periarticular osteophytes, flattening of articular services, sclerosis or lysis of subchondral bone, narrowing of the Femorotibial joint space

Question 8

Osteochondrosis of the stifle
– two common manifestations with locations
– what projection highlights these locations

Answer 8

Osteochondrosis of the femoral trochlear ridges and patella, osseous cyst – like lesions of the medial femoral condyle

Oblique

Question 9

Purpose of cranio 5* disto 10* lateral-caudoproximomedia oblique

Common name

Take this projection when you suspect what disease process?

Answer 9

Highlight medial femoral condyle

Flexed lateral oblique view

Subchondral bone cyst

Question 10

Common fracture in foals of the stifle

Answer 10

Salter-Harris type two of the proximal tibia

Question 11

Patella fracture typically due to what?

Usually involve with soft tissue structure?

Bestview to appreciate fracture line?

What are two other techniques and evaluating this type of fracture?

Answer 11

Secondary to fall or in jumpers from hitting the stifle on the fence,

medial patellar ligament

Lateral

Flexed cranioproximal-craniodistal (skyline) of the Patella or NS

Question 12

Tibial stress fracture’s
– common signalment
– common clinical presentation
– most common location

Answer 12

Thoroughbred in standardbred racehorses

Acute onset lameness

Incomplete metaphyseal and diaphyseal

Question 13

Three common radiographic findings of tibial stress fractures

Answer 13

Periosteal proliferation, sclerosis, may or may not see fracture line

Question 14

Calcinosis circumscripta

Definition, signalment, location, clinical presentation

Answer 14

Localized deposition of calcium salts in the skin and subcutaneous tissues, etiology unknown, young horses age 2 to 5 years, most common location is lateral aspect of the stifle and often bilateral, rarely causes lameness
