C
The lumbar spine’s superior articular facets face:
A. Posterior and medial
B. Inferior and lateral

A
What plane do the facet joints of the upper lumbar spine primarily lie in?
A. Coronal
B. Transverse
C. Horizontal
D. Sagittal
D
What is a facet tropism?
A. A narrowing of the IVF
B. An abnormal curvature of the lumbar spine
C. Asymmetry in the orientation of facet joints
D. A degeneration of the VB
C
What basic components make up the lumbar spine?
VB, pedicles, SAP/IAP, Pars, Laminae, SP
True or false: L1 and L2 anterior VB height is SHORTER than posterior VB height
True
What is the measurement of A to P VB height of the L3?
Trick question, it is the same height from A to P
Is L4 and L5 anterior VB height taller or shorter than posterior VB height?
L4 and L5 anterior VB height is taller than posterior VB height
Explain where and what the lateral recess is.
A space medial to the pedicles bilaterally. The area where the nerve roots exit and central canal and extend inferiority and laterally. Potentially causing radicular pain when compromised due to facet joint arthrosis or disc protrusion.
Are the lamina within the lumbar region imbricated?
No
In what direction to the TP’s project from the pedicle region?
Laterally and posteriorly
What direction do the superior facets face?
Is their surface concave or convex?
What direction do the inferior facets face?
Is their surface concave or convex?
Superior facets face posterior and medial
Concave surface
Inferior facets face anterior and lateral
Convex surface
True or false: The facet joints of the lumbar spine primarily lie within the sagittal plane in the upper lumber spine and change to coronal plane in lower lumber spine
True
To what degree are the facet joints oriented to the transverse plane?
90 degrees
Facet joint review question:
Cervical superior facet faces?
Cervical inferior facet faces?
What degree angle with the transverse plane?
Upward/posterior
Downward/anterior
45 degree angle with Transverse plane
Facet joint review question:
Thoracic facet SAP faces?
Thoracic facet IAP faces?
Joint forms what degree angle to horizontal/transverse plane? And what degree angle to the coronal plane (superior facet)?
Superior, posterior, slight lateral
Inferior, anterior, slight medial
60 degree angle to horizontal/transverse plane and 20 degree angle to the coronal plane
Facet joint review question:
What degree angle does the lumbar facet joint orient with the transverse plane?
90 degrees
What is the cervical orientation of the superior facet?
A. BUM
B. BUL
C. BM
D. BUI
A = Back, Up, Medial
aka posterior, superior, medial
What is the cervical orientation of inferior facets?
Anterior, inferior, lateral
What is the thoracic orientation of superior facets?
A. BM
B. BIH
C. BUL
D. BUM
C = Back, Up, Lateral
Aka posterior, superior, lateral
*Inferior is opposite aka anterior, inferior, and medial
What is the lumbar orientation of superior facets?
A. BUM
B. LGTBQ
C. BM
D. BS
C = Back, Medial
Aka posterior, medial
*Inferior would be opposite aka anterior and lateral
What structure extends posteriorly from SAP, is the point of contact when adjusting the lumbar spine, and attachment for ligaments and muscles?
Mammillary process
What structure is tiny, on the posterior aspect of TP base, and the attachment point for the Mozilla-accessory ligament?
Accessory process
*just lateral from the mammillary process
What is the pars interarticularis?
“Isthmus” of bone between the SAP/IAP.
SAP is above, pedicle anteriorly and laminated posteriorly
