What imaging position is used to display the femoral head in acetabulum?
What is this position used to diagnose?
Frog leg Lateral
Used to diagnose FAIS (Femoroacetabular Impingement Syndrome)
If you see a line between greater and lesser trochanters, what is it?
Intertrochanteric Crest, may be viewed from anterior through the femur due to aditional density of bone

What does the groin lateral view - plain film visualize?
Used for visualizing ant. & post. head of femur and for analyzing angle between shaft and neck/head of femur
What stands out here? What kind of image? What are the things that light up?
Gluteus maximus - longitudinal vs. the others
CT W/Contrast through upper thigh, apex of femoral triangle
Lighted up stuff = arteries (except the femur of course)
What does the white circle represent?
Adductor Canal
What structure is represented by the red star?
Articularis Genu
What does the orange line point to?
Tibial and common fibular nn

Which two of these Salter-Harris classes of femoral epiphyseal fractures have the worst prognosis?
III and IV
Identify the structures
Fibula
- Head
- Neck
- Shaft
- Tibial tuberosity
Interosseous membrane separates the anterior and posterior compartments. Where are the vessels relative to this membrane?
Anterior tibial vessels are anterior to the interosseous membrane, posterior tibial and fibular vessels are posterior to the interosseous membrane and tibialis posterior muscle
Image type? Position? Three bright dots?
Axial CT with contrast
mid-leg
Arteries
Why doesn’t a-p ankle plain film give a very good view?

What view is best for the tibiofibular articulation?
Lateral Oblique Ankle, plain film
What view is best for assessment of transverse tarsal joint?
Medial ankle, plain film
What does the lateral oblique foot plain film let you view well?
View affords assessment of the 5th metatarsal
