24
Psoas major insertion
Lesser trochanter of the femur
25
Psoas major origin
Transverse processes of lumbar vertebrae
27
Psoas major innervation and action
anterior rami of lumbar nerves (L1. L2 L3) Flexes thigh, flexes vertebral column
27
Iliacus insertion
Lesser trochanter of femur
28
Iliacus origin
iliac crest iliac fossa Anterior sacroiliac ligament
30
Iliacus innervation and action
Femoral nerve Flexes thigh and stabilizes hip
31
intertrochanteric crest and line
Crest: between the two trochanter on the posterior side Line: between the two trochanter on the anterior side
32
what are the part of the acetabulum
-lunate suface: articular portion acetabular notch acetabular fossa: non-articular portion
33
angle of inclination
- average is 126 degrees | - allows great mobility because the neck of femur is perpendicular to the acetabulum
34
what happens to the angle of inclination with age?
decreases
35
Torsion Angle in males
7 degrees
36
torsion angle in females
12 degrees
37
what is the torsion angle
the angle of inclination with the line between the two condyles
38
what bounds the gluteal region
iliac crest greater trochanter anterior superior iliac spine gluteal fold (under butt)
39
parts of the bony pelvis
hip bones sacrum coccyx (all bounded by gluteal ligaments)
40
what converts the sciatic notches into foramina?
Sacrotuberous and Sacrospinous ligament
41
Greater sciatic foramen contains
contains structures entering and leaving the pelvis
42
lesser sciatic foramen contains
contains structures entering and leaving the perineum
43
inguinal ligament
runs from anterior superior iliac spine to the public tubercules
44
Superior, Middle and inferior Clunial Nerve
-supply the skin of the gluteal region
45
Sciatic Nerve
- largest nerve | - made up of two nerve that are bound together by fasica (Tibal Nerve and Common Fibular Nerve)
46
Deep artery of the thigh
- Profunda Femoria Artery - branch of the femoral - cheif artery of the thigh
47
Hip joint type
ball and socket synovial
48
Hip joint articulations
-acetabulum with femoral head
49
acetabular labrum
increasing the depth of the acetabulum
50
transverse acetabular ligament
bridges the acetabular notch
51
iliofemoral ligament
- anteriorly to the hip joint | - prevents hyperextension
52
ischiofemoral ligament
- posteriorly to the hip joint | - weak ligament
53
pubofemoral ligament
-runs from the obturator crest and then blends with the joint capsule -tight during extension and abduction of hip resists excessive abduction of hip joint
54
what helps to stabilize the hip joint
Muscles (Medial and Lateral Rotators) and Ligaments
55
Ligament of the head of femur
- fovea - usually contains acetabular artery, a branch of obturator artery - weak at strengthening joint
56
branches of the sacral plexus
- superior gluteal - inferior gluteal - sciatic - posterior cutaneous nerve of thigh - nerve to quadratus femoral -nerve to obturator internus - pudendal
57
blood supply to the hip joint
- medial and lateral cimcumflex femoral artery (branch of deep artery of the thigh) - at the head of femor is acetabular artery (branch of obturator artery)
58
nerve supply to the hip
- anterior: femoral nerve - inferior: obturator nerve - superior: superior gluteal nerve - posterior: nerve to quadratus femorus
59
Gluteal Bursae
- separate the gluteus maximus from adjacent structures | - three types: trochanteric, ischial, gluteofemoral bursae
60
Fascia lata
- covers the muscle tensor fasciae latae on both sides | - deep fascia of the thigh
61
What two muscles make up the iliotibial tract (band)
- Gluteus Maximus - Tensor Fasciae latae (this is due to their attachment to the tract)
62
branches of internal iliac artery
- iliolumbar - lateral sacral - superior gluteal - inferior gluteal - internal puodendal - visceral branches - umbilicus - obturator
63
what does the iliotibial tract (band) run
-iliac tubercule to the anterolateral tibial tubercule on the lateral condyle of the tibia
64
What is iliopsoas muscle?
- merging of psoas major and iliacus | - chief flexor of the hip
65
What is the action of iliopsoas
-acting together: flexes and stablizes hip
66
Trochanteric bursa
Separates the deep aspect of the gluteus Maximus from the greater trochanter of the femur
67
Ischial bursa
Separates inferior border of gluteus Maximus from Ischial tuberosity
68
Gluteofemoral bursa
Separates the iliotibial tract from the superior part of insertion of vastus lateralis
