“bow legged”
outward bowing of the knees
GENUNINE VROOM
imagine someone with bow legs revving up like a genuine engine with a “vroom” sound
what is
genu valgum

inward bowing of the knees
GENU=KNEE
VALGUM-SOUNDS LIKE VALLEY
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.
what is
genu recurvatum
knee hyperextension
excessive extension
KNEE CURVE-ATUM
what are the 4 main ligaments of the anterior sacrum/pelvis/hip?
iliolumbar ligament (I)
anterior longitudinal ligament(ATE)
inguinal ligament (IN ITALY)
anterior sacroiliac ligament(IMAGINED)
“I ate in Italy and imagined ants.”
“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.”
anterior tilt cuases what muscles to be tight?
erector spinae
hip flexors
quads
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.
anterior tilt causes these muscles to be weak?
hamstrings
glutes
abdominals
HAG
WEAK DIRTY HAIR/BANGS
what type of joint is the L5-S1 intervertebral joints (lumbrosacral joints)
cartilaginous
symphysis
amphiarthrosis
triaxial
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.
what does FISH stand for?
Fibrocartilage
Ilium
Sacrum
Hyaline
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)
what type of joint is the sacroiliac joints?
synovial
plane
also fibrous, syndesmosis
diarthrosis
amphiarthrosis
“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.
what motions does the sacroiliac joints have?
nutation and counternutation
gliding (slight)
sacroiliac joints
special movements
COUNTERNUTATION
- base of sacrum moves superiorily and posteriorly
- enlarges the pelvic inlet
- ischial tuberosities approximate
- pubic symphysis seperates
- iliac crests seperate
- PSIS approximates
- ASIS flares out
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
what type of joint is teh
sacrococcygeal joint?
cartilaginous
symphysis

uniaxial

especially during

and
childbirth

sacrococcygeal ligaments
intercornual
what type of joints are the

joints- ligaments

(arcuate pubic ligament)
because its in the arch

the obturator foramen is formed by which bones?
pubic
and
