A

standing
standing on one leg
walking

31
Q

what is the q angle?

A

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
Q

what is the term “q” representing in the q angle?

A

quadratus

33
Q

what is
genu varum

A

“bow legged”
outward bowing of the knees

GENUNINE VROOM
imagine someone with bow legs revving up like a genuine engine with a “vroom” sound

34
Q

what is
genu valgum

A

“knock-kneed”
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.

35
Q

what is
genu recurvatum

A

knee hyperextension
excessive extension

KNEE CURVE-ATUM

36
Q

what are the 4 main ligaments of the anterior sacrum/pelvis/hip?

A

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.”

37
Q

anterior tilt cuases what muscles to be tight?

A

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.

38
Q

anterior tilt causes these muscles to be weak?

A

hamstrings
glutes
abdominals

HAG
WEAK DIRTY HAIR/BANGS

39
Q

what type of joint is the L5-S1 intervertebral joints (lumbrosacral joints)

A

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.

40
Q

what does FISH stand for?

A

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)

41
Q

what type of joint is the sacroiliac joints?

A

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.

42
Q

what motions does the sacroiliac joints have?

A

nutation and counternutation
gliding (slight)

43
Q

sacroiliac joints
special movements
COUNTERNUTATION

A
  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
Q

sacroiliac joints
special movements
nutation

A
  • 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?

A

cartilaginous
symphysis
amphiartosis
uniaxial

very small amount of flexion and extension
especially during
defecation
and
childbirth

what kind of accessory ligaments does the sacrococcygeal joint have?

A

fibrocartilaginous disc
sacrococcygeal ligaments
intercornual

48
Q

what type of joints are the
pubic joints?

A

cartilaginous
symphysis
amphiarthosis
uniaxial

49
Q

what are the pubic
joints- ligaments

A

superior pubic ligament
inferior pubic ligament

(arcuate pubic ligament)
because its in the arch

50
Q

what type of joint is the
acetabulofemoral joint

A

synovial
ball and socket (spheroid)
diarthrosis
triaxial

51
Q

what are the accessory ligaments of the
acetabulofemoral joint?

A

fibrous capsule
labrum
etc

52

53
Q

what are the 3 main bursae of the
acetabulofemoral joint?

A

trochanteric bursa
