Answer 4

popliteus, semimemb, semitend

Question 5

what is likely to have better absorption of the calcification of a myositis ossificans

Answer 5

muscle belly

Question 6

most vulnerable position of the hip joint? position of most laxity

Answer 6

flexion, internal rotation and adduction

Question 7

name the 3 ligaments in the hip joint that make up this capsular structure to hold the hip joint in place

Answer 7

“zona orbicularis”

iliofemoral ligament - Y ligament of bigelow - strongest ligament in the body

pubofemoral

ischiofemoral

Question 8

name the 6 deep rotary mm of the hip and innervation

Answer 8

superior gemelli - 4/5th lumbar
inferior gemelli - 4/5 lumbar
obturator internis - 4/5 lumbar 
obturator externis - obturator nn 
quadratus femoris - 4/5 lumbar
piriformis - ventral rami S1/S2

Question 9

describe how to test for a tight piriformis? what’s it innervated by?

Answer 9

second sacral nn

have patient side-lying and knee down toward table - if knee cant touch table then piriformis might be tight

Question 10

what mm are innervated by the superior gluteal nn? inferior gluteal nn?

Answer 10

sup: TFL, glute min, med
inf: glute max

Question 11

main artery to supply the lower limb

Answer 11

iliac external artery

Question 12

what special test can you do to test for hip labral issues?

Answer 12

FADDIR, FABER, flexion- internal rotation

scour test - watch for end feels

Question 13

difference b/w cam and pincer impingement

Answer 13

cam is at the femoral head where it cant glide smoothly onto the joint of the acetabulum

pincer is the deformity of the acetubulum where the it covers too much of the joint itself

Question 14

test for femoral fracture or stress fracture?

Answer 14

patellar-pubic perscussion test - using a stethoscope on top of pub tub - tapping the patella near it

(+) diminished sound compared to contralateral side

Question 15

3 tests for ITB syndrome

Answer 15

Renne’s - one legged standing and bending knee to 30-40 degrees

Nobel’s compression - (+) at 30 degrees of knee flexion

Ober’s test

Question 16

normal degrees of anteversion? abnormal degrees

test for it?

Answer 16

8-15

excessive retroversion : <8
excessive anteversion: >15

craig’s test?

watch for tibial torsions as well - measured by kneeling on stool

Question 17

in young athletes displaying groin/hip pain, what should you be concerned about? 2 conditions

Answer 17

Legg-calve perth disease - avascular necrosis of femoral head in young children (primarily in boys)

s/s - groin, hip, abdomen pain - resting may not allevaite it

slipped capital femoral epiphysis (primarily in boy sand teenage boys)

Question 18

s/s to differentiate between groin/ adductor strain vs. athlete pubalgia

Answer 18

P with resisted adduction but no TOP of adductor = athlete pubalgia

Question 19

3 common sites for an avulsion fracture or apophisitis at the pelvis

Answer 19

ischial tuberosity
AIIS
ASIS
