|
L1-L2 (do lumbar puncture L3-L5)
|
|
|
|
What is the primary flexor of the lumbar?
|
illacus (illiopsoas maintains the lumbosacral angle)
|
|
|
|
What is the normal range for the lumbosacral angle (ie Ferguson's angle)?
|
25-35 degrees
|
ferguson angle: formed two lines 1. horizontal line through ASIS and line of inclination (line thru PSIS and ASIS)
|
|
|
What does a big ferguson's angle imply?
|
Lordosis, big butt, FLEXED sacrum
|
|
|
|
What does a small ferguson's angle imply?
|
Little/flat butt, EXTENDED sacrum, risk for degenerative disk disease (make osteophytes)

|
|
What are the four types of spina bifida?
|
occulta (nothing), meningocele (CNS), myelomeningocele (CNS, nerve roots), and rachischisis (open spine)
**meningocele and myelomeningocele-->cystica |
|
|
|

|
Flexion or Extension > Sidebending > Rotation
|
|
|

How does SB and rotation of L5 affect thee sacrum?
|
Sidebending of L5-->ipsilateral sacral oblique axis. Rotation of L5-->rotate in opposite direction
|
|

|
|
|
|
What are the three subtypes of type 2 isthmic sponylolisthesis?
|
A: fracture of PARS <50 yo, B: intact elongated pars-->weekend warriors C: trauma, acute
|
|
|
|

|
abnormal immobility of the joint, bony fusion caused by ostephytes
|
|
|
|
What are S/S of osteoarthrosis?
