the pelvis
Articulations:

- L4-L5
-L5-S1
AND
- hip joint
What 3 structures compose the innominate? - correct answer-- pubis
- ilium
- ischium
Describe innominate development - correct answer-the 3 portions do not fuse until
15-17 years of age!
fusion of the 3 portions forms the acetabulum--acetabulum is not complete until
20-25 years of age

- anterior and posterior rotation RELATIVE TO SACRUM
- mvmt occurs with fxl asymmetrical limb movement
, What tests assess movement of the innominates ? - correct answer-Gillet Test /
Stork Test/ Standing Hip Flexion Test
- weight bearing side innominate POSTERIORLY rotates
--> causes relative sacral nutation
- NWB side innominate posteriorly rotates with hip flexion
Gillet Test - correct answer-aka Stork Test aka Standing Hip Flexion Test
Reference Points:
- PSIS--S2 (stork)
Standing March
NWB Leg:
assessing for PSIS to move caudally (posterior innominate rot) with hip flexion
WB leg:
as wb leg achieves end range hip motion it should also demonstrate posterior
innominate rotation (caudal PSIS mvmt)
**PSIS should drop on lifted leg side
Innominate Rotation and Pelvic Tilt - correct answer-Innominate rotation is not the
same as anterior or posterior pelvic tilting
anterior and posterior tilting is relative to lumbar spine and hip joints--the pelvis
moves as a whole
it is not the same as innominate rotation

Facets for L5 superiorly and
articular surface for ilia = C/L shaped
