Innominate/Somatic Dysfunction

Question 1

what is the job of the innominate?

Answer 1

there is gravity constantly being pulled down on your body and the legs are keeping your pelvis from being pulled to the ground. that resistance to the gravity.

locomotion, stability

there’s a lot of potential for dysfunction because of this.

Question 2

What is part of the innominate?

what else is there?

Answer 2

there is the GI system and the genitourinary system.

also because its the gateway from upper half to lower half you’re going to have a lot of circulatory and lymph going to the extremity.. this has to go through the pelvis

Question 3

Critical roles of the pelvis?

Answer 3

biomechanics function and balance

Reproduction

Elimination

Vascular + Lymphatic functions for the region

Question 4

What are the 3 bones of the innominate?

where do these come together?

what’s to note of as when you’re a kid?

Answer 4

ilium, pubis, ischium

at the acetabulum

they haven’t fused yet.. they fuse late in your teens.

Question 5

Landmarks of the anterior pelvis? (4)

Answer 5

iliac crest

ASIS

AIIS

Pubic Symphysis

Question 6

landmarks of the posterior pelvis?

Answer 6

PSIS

PIIS

Ischial Tuberosity

Question 7

Joints of the pelvis?

Answer 7

Sacroiliac Joint

Acetabulum

Pubic Symphysis

Question 8

What does “true” ligament mean?

accessory ligament?

function of ligaments?

Answer 8

from bone to bone

attach at another ligament, a tendon, or fascia

limit abnormal or excessive movements at a joint, permit normal motion, quality is slightly elastic.

Question 9

If you touch a hot stove and pull your arm away, what are your ligaments preventing?

Answer 9

that you dislocate your shoulder.. they’re preventing excessive movement as a part of the reflex response

Question 10

Major pelvic ligaments on the anterior side?

Answer 10

Sacrospinous

Iliolumbar

Anterior Sacroiliac ligament

Inguinal Ligament

Question 11

Major pelvic ligaments on the posterior side?

Answer 11

Sacrotuberous Ligament

Posterior Sacroiliac Ligament.

Question 12

explain heel strike and your innominate.

what muscles are accomplishing this?

Answer 12

Heel strike… the idea is when you’re moving forward, you’re using your muscles to move it forward.

your innominate moves posteriorly

this is done by the iliopsoas and quadriceps

Question 13

Explain toe off and your innominate?

what muscles are accomplishing this?

Answer 13

your moving that leg that was backward now forward so you’re anteriorly rotating your innominate.

you’re relaxing the iliopsoas and contracting gluteus Maximus and hamstring

Question 14

What are the hip flexors (major)

minors?

Answer 14

Iliacus and Psoas –> starts at the lumbar spine, comes down, crossing the hip joint so hip flexors

Sartorius and Rectus Femoris

Question 15

what happens if you have dysfunction of the hip flexors?

Answer 15

cause anterior rotation of the innominate or inferior shear at the pubes

Question 16

what’s the major hip extender?

minor?

what happens if you have a hip extensor dysfunction?

Answer 16

Gluteus Maximus

Semimembranosus + Semitendinosus

Bicpes Femoris

can cause posterior rotation

Question 17

Hip Adductors?

major

minor

Answer 17

Adductor Brevis, Magnus, longus

pectinous and gracilis

Question 18

Hip Abductors?

Answer 18

glut medius and minimus

TFL

Question 19

Trendelenburg sign?

what happens if we lift our right leg and its positive

what does it indicate?

Answer 19

stand on left leg, bend on the right.. you’ll have the hip drop on the right.. so it’s a positive hip drop on the right.

indicates gluteus medium weakness on the left

Question 20

What are the big external rotators?

Answer 20

Piriformis

Quadratus Femoris

Obturator internus and externus

superior and inferior gemellus

Question 21

what’s the only external rotator that attaches to the sacrum directly?

Answer 21

piriformis

Question 22

what is piriformis a big cause for?

when its flexed, what movement does it do?

when its extended, what movement does it do?

Answer 22

sciatica

abductor

external rotator

Question 23

What are secondary muscle attachments that affect your innominate?

Answer 23

Rectus Abdominus

Transversus Abdominis

Internal and External Oblique

Quadratus Lumborum

Question 24

What are the autonomic nerves of the plexus?

Answer 24

sacral sympathetic trunk –> forms ganglion impar

pelvic splanchnic

inferior hypogastric plexus

Question 25

quadratus lumborum and nerve pain?

Answer 25

quadratus lumborum has a bunch of nerves coming out of the spine around there. this can reproduce groin pain and feeling of a hernia.

Question 26

What is the gravitational line elements?

Answer 26

Auditory meatus

Acromion process

greater trochanter

body of L3

anterior 1/3 of the sacrum

lateral condyle of the knee

lateral malleolus
