Midterm Flashcards
The physical cause of fixation in the sacroiliac articulation, demonstrated through the 8 point check is from?
Ligamentous adhesions
What plane of motion is represented by an EX ilium?
Transverse
Where is the sacroiliac joint located?
In the front 1/3rd of the innominate articulation with the sacrum
How much average motion occurs at the SI joint on the sagittal plane?
7-8 degrees
How much average motion occurs in the sacroiliac joint on the transverse plane?
2mm
The iliolumbar ligament restricts what motion at L%?
Lateral Flexion
The sacroiliac ligament primarily restricts what plane of motion?
Transverse
T or F
The plane of motion represented by an AS ilium is Coronal
False
Sagittal
If a patient presents with a fixated right SI joint, deem at the bottom of the join, flat/wide gluteal muscle, toe in, short leg on the right, and hypolordosis, what pelvic listing is more likely considering the sum of all info
R ASIN
What is the minimum number of millimetres of sacral rotation (measured on X-ray) required to use the base of the sacrum as a SCO in the presence of a fixated ilium with a listing of IN?
7 mm
The ilium is subluxated PIEX on the right. The sacrum listing is P6-L. To correct this subluxation, the best lever is the right inferior lateral PSIS
True
When the pelvis is sublimated PIEX, it initially causes the weight of the patient to shift in what direction?
Posteriorward
In order to keep the body balanced upright, what is the first response to an ilium that fixates in a PIEX direction?
The hip flexes
The spinal compensation that is commonly seen in a fixated pelvic with a listing of ASIN is?
Hypolordosis
The ilium is subluxated PIIN on the left. The sacrum listing is P9-L. To correct this subluxation, the best lever is the left sacral base.
False
L ilium
