Innominate/Somatic Dysfunction Flashcards
what is the job of the innominate?
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.
What is part of the innominate?
what else is there?
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
Critical roles of the pelvis?
biomechanics function and balance
Reproduction
Elimination
Vascular + Lymphatic functions for the region
What are the 3 bones of the innominate?
where do these come together?
what’s to note of as when you’re a kid?
ilium, pubis, ischium
at the acetabulum
they haven’t fused yet.. they fuse late in your teens.
Landmarks of the anterior pelvis? (4)
iliac crest
ASIS
AIIS
Pubic Symphysis
landmarks of the posterior pelvis?
PSIS
PIIS
Ischial Tuberosity
Joints of the pelvis?
Sacroiliac Joint
Acetabulum
Pubic Symphysis
What does “true” ligament mean?
accessory ligament?
function of ligaments?
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.
If you touch a hot stove and pull your arm away, what are your ligaments preventing?
that you dislocate your shoulder.. they’re preventing excessive movement as a part of the reflex response
Major pelvic ligaments on the anterior side?
Sacrospinous
Iliolumbar
Anterior Sacroiliac ligament
Inguinal Ligament
Major pelvic ligaments on the posterior side?
Sacrotuberous Ligament
Posterior Sacroiliac Ligament.
explain heel strike and your innominate.
what muscles are accomplishing this?
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
Explain toe off and your innominate?
what muscles are accomplishing this?
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
What are the hip flexors (major)
minors?
Iliacus and Psoas –> starts at the lumbar spine, comes down, crossing the hip joint so hip flexors
Sartorius and Rectus Femoris
what happens if you have dysfunction of the hip flexors?
cause anterior rotation of the innominate or inferior shear at the pubes
what’s the major hip extender?
minor?
what happens if you have a hip extensor dysfunction?
Gluteus Maximus
Semimembranosus + Semitendinosus
Bicpes Femoris
can cause posterior rotation
Hip Adductors?
major
minor
Adductor Brevis, Magnus, longus
pectinous and gracilis
Hip Abductors?
glut medius and minimus
TFL
Trendelenburg sign?
what happens if we lift our right leg and its positive
what does it indicate?
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
What are the big external rotators?
Piriformis
Quadratus Femoris
Obturator internus and externus
superior and inferior gemellus
what’s the only external rotator that attaches to the sacrum directly?
piriformis
what is piriformis a big cause for?
when its flexed, what movement does it do?
when its extended, what movement does it do?
sciatica
abductor
external rotator
What are secondary muscle attachments that affect your innominate?
Rectus Abdominus
Transversus Abdominis
Internal and External Oblique
Quadratus Lumborum
What are the autonomic nerves of the plexus?
sacral sympathetic trunk –> forms ganglion impar
pelvic splanchnic
inferior hypogastric plexus
quadratus lumborum and nerve pain?
quadratus lumborum has a bunch of nerves coming out of the spine around there. this can reproduce groin pain and feeling of a hernia.
What is the gravitational line elements?
Auditory meatus
Acromion process
greater trochanter
body of L3
anterior 1/3 of the sacrum
lateral condyle of the knee
lateral malleolus
