Ortho Final Review Lumbopelvic Flashcards
What is the basic pelvic anatomy?
SI Joints
Pubic Symphysis
What is the basic SI Joint Anatomy?
Articulation between Sacrum and Coxal Bones that are supported by thick ligaments anteriorly and posteriorly
What plane of motion are pelvic facet joints?
Primarily in the sagittal plane, facilitating flexion and extension
How many planes of motion does pelvis move in?
All 3 planes of motion
Lumbar contribution Flexion/Extension
Flexion= 50
Extension= 20
Lumbar contribution in sidebending
Sidebending= 30
Lumbar Contribution in rotation
Rotation= 32 each side
Rotation and Sidebending occur _________
TOGETHER
In lumbar flexion, the sacrum _________________
counter nutates, PPT
In lumbar extension, the sacrum _______________
nutates, APT
The pelvis can:
- Anteriorly or Posteriorly Tilt
- Hike or Drop
- Rotate on top of the Femur
What happens in a PPT?
Abs are pulled up and hip extensors pulled down
Hip flexors and back extensors are stretched
What happens in a APT?
Back extensors pull up, and hip flexors pull down
Hip extensors and abs stretch
What are the special tests used for the lumbar spine?
SLR
Slump Test
Prone Knee Flexion
Gower’s Sign
What happens when the psoas is shortened?
The lumbar spine is pulled into further extension
What is the SLR test?
Pt in supine, leg passively flexed by PT
Test is positive if there is pain in back/leg between 30-70 degrees
*Neural tension on the sciatic nerve
What is the slump test?
Patient in sitting, flexes in trunk first, then cervical, then extension, then knee one at a time
* abnormal dural tension
