Anatomy Didactic Week 5 Questions and Answers
1. what does pelvic-on-femoral osteokinematics refer to: when feet are fixed to floor and pelvis moves about fixed femoral heads
2. pelvic-on femoral in the sagittal plane: APT and PPT
3. pelvic-on femoral in the frontal plane: hip hike is abduction ...
1. what bones make up the hip joint: head of femur and acetabulum of hemi-pelvis (a ball and socket joint)
2. what motion do all 3 hip ligaments become taut in: hip extension
3. strongest hip capsule ligament and what it is most taut in: iliofemoral liga- ment, taut in extension (good for
standing since it is anterior to hip joint)
4. where does the iliofemoral ligament span: intertrochanteric line to the anterior inferior iliac spine, iliac portion of
acetabular rim
5. what reinforces the inferior aspect of the hip capsule: pubofemoral ligament
6. where does the pubofemoral ligament span: anterior inferior ac the pubic ramus and obturator etabulum
membrane (inserts with iliofemoral lig trochanter) to at
lesser
7. when is pubofemoral ligament taut: in extension and abduction
8. what ligament supports the hip joint posteriorly: ischiofemoral ligament
9. where does the ischiofemoral lig attach, what about thickness of its fibers-
: acetabular rim posterior and inferiorly, connects to labrum and greater trochanter
thinner fibers on posterior side
10.what does the ischiofemoral ligament resist: internal rotation and extension upper fibers taut in adduction
inferior fibers taut in flexion of hip
think ischiofemoral does a lot... IRE. upper for ADd, lower for FLexion
11.what is name of fibrocartilage stricture along perimeter of acetabulum: ac- etabular labrum (for stability)
12. what arises from the acetabulum and inserts on a special area of femur: -
ligamentum teres
13.where does the ligamentum teres insert: the fovea capitis (no articular carti- lage at this spot)
, Anatomy Didactic Week 5 Questions and Answers
14.what runs with the ligamentum teres and what does it do: the obturator artery (provides blood supply to
head of femur)
15.what is lumbopelvic rhythm: spine and pelvis can rotate in same or opposite directions
(ex. APT but extend your spine ex. PPT and
hunch over)

16.what does pelvic-on-femoral osteokinematics refer to: when feet are fixed to floor and pelvis moves about
fixed femoral heads
17.pelvic-on femoral in the sagittal plane: APT and PPT
18.pelvic-on femoral in the frontal plane: hip hike is abduction hip dip is adduction
(thinking about the hip of the leg on the ground lower hip is
ABducted, upper hip is Adducted.)
19.pelvic-on femoral in the transverse plane: standing on R leg, turn toward left is lateral rotation
standing on R leg and turn toward it is medial rotation
20.what bones form the knee joint: condyles of femur and tibia (tibiofemoral joints) and patello-femoral
articulation
21.what planes does knee operate in: sagittal flex/ext horizontal for int/ext
rotation
22. during flexion what happens to femoral condyles and tibia (think roll and slide)
during extension what happens: flex: femoral condyles slide anteriorly and roll posteriorly, tibia rolls and glides
posterior
ext: femoral condyles slide posteriorly and roll anteriorly, tibia rolls and glides anterior is slide vs glide important
think SLIDE for femur is what causes movement
23.what is special about the angle of the alignment at knee: femur angles medially to approach tibia, but tibia is flat
articular surface, so femur medial condyle needs to be longer. medial condyle also extends farther distally
24.what is the longitudinal angle of the knee: 170-175 degrees
25.is the knee varus or valgus: valgus
(knock knee is excess valgus, bow legged is excess varus)
26.anterior joint capsule of knee: quad tendon, patellar retinacular fib the vastus lat & med, and IT ers
tract) (from
