True or False?
Running, Yoga, skating, baseball and so many other sports play a role in the hip joint and pelvic girdle.
True
Hip joint is fairly stable due to its bony
architecture, strong ligaments, and large muscles.
The hip joint functions both in
weight bearing and locomotion
This is considered the longest bone in the body
Femur
Make sure to know the bony landmarks on the picture
Make sure to know the bony landmarks on the picture
Pelvic bones is divided into three parts… What are they?
Pubis, Ilium, and ishcium
Right and left pelvic bone joined together posteriorly by the ….
sacrum
We have learned so far about two joints in the hip and pelvic girdle? What are they?
Pubis Symphysis, Hip joint
This joint is considered a ball and socket joint; the aceteumbium fits with the head of the femur
hip joint
This is considered a ampthardial joint
pubis symphysis
What is the anterior and posterior pelvic rotation?
anterior- Illiac crest tilts forward in a saggital plane.
Downward rotation
Posterior- Illiac crest tilts backward in a saggital plane.
Upward rotation
During anterior pelvic rotation…what happens to the pubis , illaic crest, and tailbone.
Pubic moves inferiorly while the illac crest and tailbone move superiorly
During posterior pelvic rotation… What hapens to the pubis, Illiac crest, and tailbone?
Pubis moves superiorly whie illac crest and tailbone move inferiolrly
what plane do left and right lateral pelvic rotation occur?
Frontal
left pelvis moves inferiorly relative to right pelvis
Left lateral pelvis rotation
Right pelvis moves infertioly relative to the left pelvis
right lateral pelvis rotation
Right iliac crest moves anteriorly relative to left iliac crest
Left transverse pelvis rotation
Left iliac crest moves anteriorly relative to right iliac crest
right transverse pelvis rotation
Hip flexion muscles:
Hip Abductors-
Hip Extensors-
Hip adductors-
Origin on anterior pelvis
- Origin just below iliac crest, laterally
Origin posterior sacrum/ischial tuberosity
Origin on pubis
Thick band of fascia connect tissue
ilotibial band
The ilotibail band has insertion at
Tensor Faciae Lataea and gluetus maximus
Passes across ….. trochanter of the femur as the hip joint flexes and extends
greater trochanter of the femur
Trochanteric bursa is located between ……………………. to facilitate this movement
iliotibial band and greater trochanter to facilitate this movement
Considered the largest nerve in the body
Sciatic Nerve
Passes just inferior to ………… or through it
pirisofirms mucsle
Sciatic nerve intervates at where
Innervates upper and lower leg, and foot
Tightness in pisiforms may compress …… nerve
sciatic nerve
what is the appllication of illopsosas muscle?
Raises and lowers lower extremity from floor while supine (leg raise)-can strain lower back as will pull on lower back while raising thighs; contracts in sit-ups when hips are not flexed
