25
what is the acetabulum lunate surface?
like a 2 tiered stadium lunate higher "moon lower bowl- being deeper for the acetabulum fossa
26
where is the iliopectineal (arcuate) line?
on the pubis
27
what make's up the iliopectineal line?
acurate line of the ilium pectineal line
28
where is the iliopectineal eminence?
bump technically on the pubis
29
what does ramus mean?
branch
30
acetabulofemoral joint (hip joint) what are the forces that go through the hip from lightest to heaviest?
standing standing on one leg walking running
31
what is the q angle?
a line drawn from the ASIS through the center of the patella another line drawn from the center of a patella to the center of the tibial tuberosity
32
what is the term "q" representing in the q angle?
quadratus
33
what is genu varum
"bow legged" outward bowing of the knees ## Footnote GENUNINE VROOM imagine someone with bow legs revving up like a genuine engine with a "vroom" sound
34
what is genu valgum
"knock-kneed" inward bowing of the knees | GENU=KNEE VALGUM-SOUNDS LIKE VALLEY ## Footnote Imagine a person standing with their knees bent inward like a bow, forming a shape that resembles the letter "G" for "genu," which means knee. Additionally, the word "valgum" sounds a bit like "valley." So, you can visualize the knees forming a valley-like shape due to their inward angulation.
35
what is genu recurvatum
knee hyperextension excessive extension ## Footnote KNEE CURVE-ATUM
36
what are the 4 main ligaments of the anterior sacrum/pelvis/hip?
**i**liolumbar ligament (I) **a**nterior longitudinal ligament(ATE) **in**guinal ligament (IN ITALY) **a**nterior sacroiliac ligament(IMAGINED) | "I ate in Italy and imagined ants." ## Footnote "I ate" represents the "iliolumbar ligament." "in Italy" represents the "inguinal ligament." "and" represents the "anterior longitudinal ligament." "imagined" represents the "anterior sacroiliac ligament." "ants" represents the "anterior ligaments."
37
anterior tilt cuases what muscles to be tight?
erector spinae hip flexors quads ## Footnote Anterior tilt" reminds you of the pelvic position. **"Spills the water"** illustrates the tipping motion forward, as if water is spilling out the front of the pelvis. **Quads get a grip!"** "Pelvic anterior tilt" reminds you of the condition. "Erector Spinae" refers to the muscles along the spine. "Hip Flexors" are the muscles responsible for flexing the hip joint. "Quads" refer to the quadriceps muscles in the front of the thigh. "Get a grip" emphasizes how these muscles become tight when the pelvis tilts forward. **You can visualize these muscles gripping or tightening as if they're trying to pull the pelvis into an anterior tilt, reinforcing the association between the condition and the muscles involved.**
38
anterior tilt causes these muscles to be weak?
hamstrings glutes abdominals ## Footnote HAG WEAK DIRTY HAIR/BANGS
39
what type of joint is the L5-S1 intervertebral joints (lumbrosacral joints)
cartilaginous symphysis amphiarthrosis triaxial ## Footnote Low 5 Sips and 1 Sips together at the cartilaginous symphony." "Low 5" refers to L5, the lumbar vertebra. "Sips and 1 Sips" sounds like "S1," the sacral vertebra. "Together at the cartilaginous symphysis" reminds you of the type of joint, which is cartilaginous and of the symphysis subtype.
40
what does FISH stand for?
Fibrocartilage Ilium Sacrum Hyaline ## Footnote It seems like "FISH" is being used as an acronym to remember the components of the pelvis. Each letter represents a part: F: Fibrocartilage (referring to the intervertebral discs) I: Ilium (one of the bones of the pelvis) S: Sacrum (another bone of the pelvis) H: Hyaline (likely referring to hyaline cartilage, which is found in various joints including those of the pelvis)
41
what type of joint is the sacroiliac joints?
synovial plane **also fibrous, syndesmosis** diarthrosis amphiarthrosis ## Footnote "Straighten Sacroiliac: Planes and Fibrous Synapses" "Straighten" reminds you of the plane nature of the joint. "Sacroiliac" specifies the joint in question. "Planes" reminds you that it is a plane joint. "Fibrous Synapses" hints at the fibrous nature of the joint (syndesmosis), which is an additional classification for the sacroiliac joint.
42
what motions does the sacroiliac joints have?
nutation and counternutation gliding (slight)
43
sacroiliac joints special movements COUNTERNUTATION
1. base of sacrum moves superiorily and posteriorly 2. enlarges the pelvic inlet 3. ischial tuberosities approximate 4. pubic symphysis seperates 5. iliac crests seperate 6. PSIS approximates 7. ASIS flares out
44
sacroiliac joints special movements nutation
- base of the sacrum moves inferiorly and anteriorly - enlarges the pelvic outlet - ischial tuberosities move apart - symphysis pubis approximate - PSIS separates - ASIS flares in
45
what type of joint is teh sacrococcygeal joint?
cartilaginous symphysis amphiartosis uniaxial
46
what motions does the sacrococcygeal joint have?
very small amount of flexion and extension especially during defecation and childbirth
47
what kind of accessory ligaments does the sacrococcygeal joint have?
fibrocartilaginous disc sacrococcygeal ligaments intercornual
48
what type of joints are the pubic joints?
cartilaginous symphysis amphiarthosis uniaxial
49
what are the pubic joints- ligaments
superior pubic ligament inferior pubic ligament (arcuate pubic ligament) because its in the arch
50
what type of joint is the acetabulofemoral joint
synovial ball and socket (spheroid) diarthrosis triaxial
51
what are the accessory ligaments of the acetabulofemoral joint?
fibrous capsule labrum etc
52
what are the acetabulofemoral joint (hip joint) ROM
flexion 110-120 ext- 10-15 internal/medial rotation 30-40 external/lateral rotation 40-60 aBduction 30-50 aDduction 30
53
what are the 3 main bursae of the acetabulofemoral joint?
trochanteric bursa ischial bursa gluteofemoral bursa
54
what nerve exits the sacral hiatus?
S5 and coccyx nerve
55
what articulate with the apex of the sacrum?
base of the coccyx
56
what bones make up the os coxae/pelvis?
ilium ischium pubis
57
how many bursaes are around the hip joint?
11
58
what are the abnormal end feels of the hip joint?
bony and late myospasm
59
which bone is not a part of the ox coxae? sacrum ischium pubic bone ilium
sacrum
60
the obturator foramen is formed by which bones?
pubic and ischium
61
true or false? the sacroiliac joint is covered in fibrocartilage and the sacrum in hyaline cartilage?
true
62
63
Posterior tilt- lean in
Nutation
64
Anterior tilt- lean out
Counternutation
