Q

what is the function of the angle of inclination

A

orients the femoral shaft more laterally and provides a better lever arm for the hip abd

Q

at what angle of inclination is the hip less stable

A

coxa valga

brings the trochanter inwards so it is less efficient and has less of a pull

25
what is the orientation of the the femoral head
anterior lateral inferior
26
what is the center angle
the degree of overhang of the acetabulmn over the femoral head center of the femoral head to the lip of the acetabulm
27
what happens if there is too much over hang
impingment
28
what is the def of dysplagia
innsufficient acetabular coverage
29
what ligament spans the ace notch
the transverse notch
30
what is the function of the labrum
increases joint stability
31
is the joint capsule reinforced
yes it has ligamentous reinforcement z in the front
32
what are the three movements that are allowed at the hip
flex/ext IR/ER abd/add
33
how much more converage does the labrum provide
20%
34
what are the ligament the reinforce the joint capsule of the hip
iliofemoral (ant) pubofemoral (ant) ischiofemoral (post)
35
what three muscle make up the iliopsoas
illiacus psoas major and minor
36
what muscle make up the quad
rec fem vastus lateralis, medialis, intermedius
37
what is the function of the satoruis
flexes the hip lateral rot of the hup and abd
38
what muscle make up the add region
pectinus add magnus, brevis , longus
39
what three muscle instert onto the the greater trochnater
piriformis glute min and med
40
what muscle insert onto the greater trochanter ridge
sup gemellus inf gemellus obertator internus
41
is the hamstring a two joint or one joint muscle group
two joint knee and hip
42
what muscles produce hip flexion
quads - rec fem iliopsoas - primary hip flexor TFL
43
when is the rec fem most powerful in hip flex
when the knee is flexed
44
what muscel produce hip ext
glute max - most powerful hamstring
45
secondary flexors
pectinus sartoruis garcilius add longus and magnus
46
what attaches to the pes anserine
SGT sartorius garcilius semitendinosis
47
secondary extensors
pectinus add longus and magnus garcilius
48
what muscle do hip abd
glute med - most powerful glute min TFL
49
as the hip flexes what happens to the adb power of the glute med
it loses the power of abd as the hip flexes and becomes more of a internal rotator
50
trandelenburg sign signifies what
weak abd
51
what muscles do hip ADD
add magnus - most powerful add longus - most injuryed add brevis pectinus gracilius
52
what muscle ER the hip
piriformis obturator internus obturator externus gemellus inf and sup quad femoris
53
what are 2ndary ER
glute med and max sartorius
54
what does hip IR
this is not a primary function of any of the muscle at the hip TFL and the naterior fibers of glute med and min contribute
55
alvusion frcatures and rec fem
AIIS
56
alvusion frcatures and hamstrings
ischial tube
57
alvusion frcatures and sartoruis
asis
58
alvusion frcatures and adductor longus
pubis
59
where are bursa located
near tendons and joint
60
what is bursitis
when the bursa become inflammed and painful
61
where are the bursa located in the hip

66
where does the femoral art run

67
what makes up the femoral trinangle
borders: inguinal ligament, abd longus, sartourius, floor: pectinus, and iliopsoas what runs: femoralart, vien, nerve, inguinal lymph nodes
68
what is the loose pack position for the hip
