1. Know the bones of the pelvis and spine, both child as well as adult.
The pelvis of a child has 15 bones, adults have 4
2. Know the muscles of the spine, especially the posterior portion of the spine and
spinal column, such as, all the divisions of the erector spinae,
Iliocostalis
Longissimus
Spinalis
**** LOOK IN BOOK AND NOTES TO STUDY THIS ***
superficial muscles of the spine and their innervation. Knowledge of origins and
insertions would be helpful.

3. Know the IVD structure and function. Know how it receives nutrition.
There are 23 IVD’s, 2 cm is lost from morning to night d/t gravity
During standing, the water within the gelatinous matrix of the nucleus escapes
into the vertebral body thru microscopic pores linking the casing of the nucleus
and the spongy bone underlying the vertebral plateau.
At night water is drawn into the nucleus and the disc regains its orginal thickness.
If a constant load is applied then the loss of thickness is not linear but exponential
suggesting a dehydration process proportional to the volume of the nucleus. The
disc never recovers the initial thickness = AGING. This will cause joint
disturbances and open athe interspace posteriorly which thes will cause
osteoarthritis.
Main retaining lig of spine
2 main parts: Nucleus pulposus and annulus fibrosus
Thicker in front than in back in the lubar and cervical spines; same thickness in
thorasic spine.

Sacrosciatic ligament is made of the sacrospinous and sacrotuberous lig.
Interspinous line runs from PSIS to ASIS.
LIG. OF THE SACROILIAC JT.
1.Ant. sacroiliac lig
2.Interossious sacroiliac lig.- main that holds ilium to sacrum
3. Posterior sacroiliac lig. – join S3-4 to the PSIS
LIG ATTACHING SACRUM TO ISCHIUM
1. Sacrosciatic Lig. –Sacrotuberous lig (glut and biceps femoris attach,
sometimes considered a muscle.)
- Sacrospinous lig- sacrum and coccyx to spine of
ischium.
LIG OF PUBIC SYMPHYSIS
1.Superior pubic lig.
2. arcuate pubic lig.
LIG OF THE LUMBOSACRAL JT.
1.Iliolumbar ligament – L4-5 to pelvis (lumbosacral lig is part of this)
LIG OF LOWER SPINAL COLUMN TO PELVIS
1. Anterior longitudinal lig
2. post. Longitudinal lig
3. intervertebral disc
4.
5.
6.
7.
8.
articular capsules
ligamenta flava – thickest in lumbar, connects lamina
supraspinous lig – causes tenderness, sp’s from C7- S1-2 tubercle
Interspinous lig – runs between SP’s
Intertranverse lig.
6. Know the 14 different physical findings that a patient can exhibit when he/she has
suffered a sacral subluxation, both acute and chronic
7. Know the primary and secondary curves of the spine and of the body.
Arch of foot – secondary
Heel – Primary
Knee – secondary
Butt/Pelvic- primary, concave
Lumbar – Secondary, compensatory
Thoracic – Primary, concave
Cervical – secondary, compensatory
Head - primary
8. Know the gravity lines of the body.
Normal spine: runs from the tip of the mastoid process through the front of the
shoulder, greater trochanter, back of the patella, and about one inch anterior to the
external malleolus.
Normaly the line of weight likes posterior to the hip joints
9. What is the primary premise of Logan Basic Technique?
The body of the lowest freely moveable vertebrae rotates towards the low side of
the sacrum.
10. What is the size of the SI joint?
2 ¾ inches long (63-64mm), >1 inch (29mm) deep
11. What is the origin and insertion of the Biceps Femoris muscle?
The long head of the biceps femoris attaches to the sacrotuberous ligament.
Attaches to the ASIS along with the sarrtourious muscle
12. What is lumbopelvic rhythm?
Rocking motion of ilium and sacrum during gait (forward leg would be PI PSIS
with AI sacrum)
13. What is eccentric rotation?
PSIS is posterior/ inferior during ambulation. Will be the shortened leg
functionally.
14. What is concentric rotation?
Anterior/ superior PSIS
15. What are the two main orthopedic tests to determine piriformis syndrome?
Pace sign and Beatty sign
16. What is osteitis pubis?
A disorder of the pubic symphysis characterized by pubic pain and joint
disruption. It develops secondarily to inappropriate biomechanical forces
17. Describe the different Types of lumbarization/sacralization.
1A - 1 widened TP may form a jt, 1B – Both TPs
2A – 1TP forms a jt with the sacrum ; 2B – Both TPs
3A – 1 TP is fused on the sacrum ; 3B – both TPs
4 – Both 1 TP is fused and the other is a jt.
** only adjust a 1A/B, and a 2A (in prone)
18. What are the Joints of Von Luschka and where are they found?
These are extra joints on the lateral aspect of the bodies. Aka uncinate or
unciform processes, or uncovertebral joints. These are diarthrodial joints with
synovial fluid. You can see these are white on x-rays after a sprain.
19. Describe a lumbar vertebra.
5 of them
Height is greater anterior than post., no ribs attach.
20. Describe a thoracic vertebra
Height is smaller ant, than post.
Rib or ribs are attached to it.
12 of them
21. Describe a lower cervical vertebra
These are typical vertebrae. C3-7.
22. Describe an upper cervical vertebra
C1-C2. Atlas and axis. During rotation the atlas drops vertically 2-3 mm. these are
atypical vertebrae.
23. Describe the iliopsoas muscle.
3 PARTS: Psoas major – from TP’s of lumbars – lesser trochanter of femur.
Psoas minor – from side of T12 and IVD – pectin pubis and
iliopectineal eminence
Iliacus – from sup 2/3 of iliac fossa, crest, iliolumbar lig, and upper
lateral sacrum to the lesser trochanter with some fibers into the femur.
24. Describe the Sartorius muscle
Longest muscle in the body. From ASIS to the medial knee (pens anserine)
25. What is the superficial back line of fascia and describe its pathway.
A fascia plane that starts at plantar toes and runs up with calcaneus,Achilles
tendon, condyles of femur, HS, Ischial tuberosity, Sacrotuberous ligament,
sacrum, sacrolumbar fascia/erector spinae, occipital ridge, galia
aponeurotica/scalp fascia, and frontal brow ridge.
26. What is the most common wedged vertebra?
L5
27.Describe ankylosis.
Ligaments being reinforced to prevent or decrease vertebral rotation.
Can be slight to complex.
Fixation can progress from affecting the muscles to affecting the length of
ligaments to eventually deposition of calcium in the ligaments and adjacent
muscles.
It obstructs normal restoration of the spine by holding the vertebrae in their
distorted position.
If normalized where the need for calcium in ligaments and muscles are no longer
required, the body can withdraw it.
