Flashcards in COM OS II Deck (33):
1

hip flexors

iliacus
psoas major, minor
sartorius
gracilis
adductor longus/brevis
pectineus
rectus femoris

2

medial hip extensors

semitendinosus
semimembranosus
gracilic
sartorius

3

lateral hip extensors

biceps femoris
glut max
adductor magnus

4

what muscles insert on tuberosity of the ischium?

biceps femoris
semimembranosus
semitendinosus

5

glut max

hip extensor

6

adductor longus

gracilis and pectineus

7

medial adductors

adductor longus, brevis, adductor magnus
pectinius
gracilis

8

adductor groups attach to

all attach to the pubic ramus and the mediar and/or posterior femur

function of all is ADduction

9

ABductors

gluteus medius
gluteus minimus
tensor fascia lata

10

glut medius

attaches to ilium and lesser trochanter

11

glut min

attaches to ilium and lesser trochanter

12

external rotators

piriformis
obturator internus
obturator externus
gemellus superior
gemellus inferior
quadratus femoris

13

muscle that causes sciatica in 10-12% of the population

periformis, sciatic nerve pierces periformis

14

periformis as abductor and rotator

abduct when hips is flexed
but
external rotators when hip is extended

the ONLY rotator to connect directly to sacrum

15

Anterior Innominate rotation: position of the ASIS and the PSIS

ASIS rotates inferiorly and PSIS rotates superiorly

16

Superior Innominate shear

ASIS goes superior, PSIS goes superior

17

"inflare"

ASIS is pushed more medially

18

"outflare"

ASIS is pushed more laterally

19

Pubic shear

r or l pubis goes up, the other goes down.

20

the "major hip flexors"

iliopsoas

21

the "lesser" hip flexors

sartorius and rectus femoris

22

Innominate testing: static anterior landmark assessment

Anteriorly: greater trochanters, pubic symphysis, iliac crest, ASIS

Posteriorly: PSIS

Internal/external leg roll
medial malleolus

23

Innominate testing: dynamic testing

AP compression
lateral to medial compression
flexion testing (standing and seated)

24

a patient with a positive standing flexion sign and a positive seated flexion sign indicates a problem with the

sacrum

25

a patient with a positive standing flexion sign and a negative seated flexion sign have a problem in the

innominate

26

a patient with a negative standing flexion sign and a positive seated flexion sign indicate a problem in the

sacrum

27

side with the + standing flexion test indicates the rest of the exam is performed on the

the same side

28

if a standing flexion test indicates the PSIS on the R side is dysfunctional, what other land marks are assessed?

the sacral sulcus and the ASIS

29

standing flexion test

patient stand, doc behind patient with eyes at level of PSIS

contacts the inferior aspect of the PSIS

on the dysfunctional side the SI locks prematurely, and the PSIS will elevate first and usually the fatherest. this is the side of the "positive test"

the ilium is dysfunctional in relation to the sacrum

30

+ standing flexion test

ASIS superior
PSIS inferior
sulcus deep
leg length shorter

posterior innominate rotation

31

+ standing flexion test

ASIS superior
sulcus equal
leg length shorter

superior innominate shear

32

+ standing flexion test

ASIS is inferior
PSIS is inferior
sulcus equal
leg length longer

inferior innominate shear

33

+ standing flexion test

ASIS inferior
PSIS superior
sulcus shallow
leg length longer

Anterior innominate rotation
