Pelvic Girdle CDM and Treatment
Planning
Functions of the Pelvis - correct answer-1) Load Transfer
2) F Generator
3) Primary Stabilizer/COM
Describe the pelvis composition - correct answer-2 innominates and the sacrum form
the pelvis
Articulations:
- pubic symphysis
- Sacroiliac Joints
When considering the pelvis what other structures must we consider due to
functionality? - correct answer-Pelvis must be considered in tandem with
- 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
Movement of Pelvis - correct answer-Anterior and Posterior Rotation
&
Rotation to Left and Right
Describe movement of the innominates - correct answer-Sagittal Plane:
- 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
Describe the sacrum - correct answer-Fusion of S1-S5
Facets for L5 superiorly and
articular surface for ilia = C/L shaped
has the sacrum-coccygeal joint!
Describe sacral motion - correct answer-Sacrum can rotate 1-3degrees
Sacrum can translate <1mm
Motion is always relative to ilia!
