|
|
Can a bicondylar joint normally abduct or adduct?
|
No. This would cause a subluxation or dislocation.
|
|
What are the characteristics of the diarthrodial (synovial joint)?
|
Joint capsule, synovial fluid, hyaline cartilage, surrounding ligaments, movement b/t two surfaces.
|
|
How do two inominate bones move on a fixed sacrum?
|
Oblique ant or posterior rotation (aka tilt).
|
|
What sacral levels contain the SI joints articular surfaces?
|
Usually S1-S3, rarely they extend to S5
|
|
In the 1988 study, Pitkin and Pheasant concluded what about SI movement in dysfunction?
|
There are 2 possible antagonistic SI movement: 1)Paired R ant inom/L post inom 2) Paired R post inom/L ant inom
|
|
What is the nerve supply for the SI joint?
|
Dorsal rami of spinal nerves S1-S4
Also read, Lumbar and sacral nerve roots L5-S4 |
|
What major mm groups have an influence on the SI joint?
|
Major: Hip ext, flex, IR, ER
Minor/improbable: Hip abd, add except as they may fx as IR |
|
What internal rotators are mentioned as possibly influencing SIJ?
|
TFL, Glut min, Ant fibers of glut med.
|
|
Describe the actions of gluteus medius?
|
Generally: abducts and stabilizes
Ant fiber IR and flx. Post fiber ER and abd. |
|
What is the relationship between hip ROM and hip OA?
|
For every plane of limited hip ROM, chance of developing OA is greater.
|
|
How many degrees mark a sig diff in hip IR, R vs L?
|
10 deg, make note 15 deg, yellow flag.
|
|
What structures can be assessed using the Thomas test? How?
|
Rectus, IT band, iliopsoas, TFL.
Hip ext + knee ext= IP Hip ext + hip add= TFL(TFL as abd?) and ITB Hip ext + knee flx= Rectus |
