Imaging and Important things to know Flashcards
What is the primary artery of the thigh?
deep femoris A
What thigh vascularization is augmented with obturator A (runs with Obturator N)?
Femoral A
What blood supply supplies the anterior compartment?
Anterior tibial A.
What blood supply supplies the posterior compartment?
Posterior tibial A.
What blood supplies the lateral compartment in leg?
Fibular A
What are the main blood supplies for the foot?
dorsalis pedis (dorsal off of anterior tibial A.) medial and lateral plantar A (posterior tibial A.)
What is important of the hip joint (iliofemoral ligament to be precise)?
it resists hyperextension, allows flexion in the lumbar spine
Hiltons law?
joint supplied by same nerves as the muscles that pass over
What is the pivot shift test?
laxity/tear of ACL with tibia anterior, when leg put into extension, IT band will pull tibia posterior, flexion IT band will release tibia, allowing anterior deviation
When PCL is torn, what would you use to test?
POSTERIOR drawn test, apply posterior push on tibia, vice versa for ACL tear
What is quad active test?
torn pcl push = posterior drawer, activate quads, tibia slides forward
What are the ABCs of X-rays?
A lignment of fractures/dislocations & (adequacy)
B one cortex: follow through checking for abnormalities
C artilage: evaluate joint space
What is a SLAP tear and what can you see on images?
superior labrum anterior posterior tear, contrast will seep into labrum and will see lots of white around where labrum is (T2)
How can Hill-Sachs deformity be diagnosed?
hx of many dislocations, divot in humerus head (anterior dislocation)
How can sail sign be diagnosed?
there will be an efusion of fat pads after fracture in adults radial fracture, in kids supracondylar fracture
