Hip Joint/Anterior/Medial Thigh Flashcards
What are the bony landmarks on the femur? (12)
- head
- neck
- greater trochanter
- lesser trochanter
- intertrochanteric line
- linea aspira
- M/L supracondylar ridge
- M/L epicondyle
- intercondylar fossa
- adductor tubercle
- patellar surfaces
- angles
what connects the linea aspira to the lesser/greater trochanters?
- pectineal line
- gluteal tuberosity
name the angles of the femur
- angle of inclination
- angle of torsion
- Q angle
what attaches to the greater trochanter?
abductors and lateral rotators (ERs)
what attaches to the lesser trochanter?
iliopsoas muscle
what attaches at the intertrochanteric line?
iliofemoral ligament
what is the linea aspira?
a ridge on the post femur that the adductors attach to
where is the pectineal line?
runs from linea aspera to lesser trochanter
where is the gluteal tuberosity?
runs from linea aspera to greater trochanter
what is the angle of inclination?
angle between neck and shaft of the femur.
Results in distal femur moving medially to more effectively support the body when standing
what is the Q angle?
the angle between the shaft of the femur and tibia.
Determines valgus/varus at the knee
what are ligaments in the hip?
- Iliofemoral
- pubofemoral
- ischiofemoral
- ligament of head of femur
pectineus prox attachment
pubic bone/superior ramus
pectineus distal attachment
femur/pectineal line
pectineus innervation
femoral and obturator nerves (L2-3
pectineus action
flex, adduct, and IR femur at hip joint
iliacus prox attachment
iliac/iliac fossa
iliacus distal attachment
femur/lesser trochanter
iliacus innervation
femoral nerve (L2, 3)
iliacus action
- flex femur at hip
- flex trunk at thigh
psoas major prox attachmen
lower T and upper L vert bodies and transverse p
psoas major distal attachment
femur/lesser trochanter
psoas major innervation
lumbar plexus (L1, 2)
psoas major action
- flex femur at hip
- can also flex trunk at thigh
sartorius prox attachment
ilium/ASIS
sartorius distal attachment
prox/med/post tibia
sartorius innervation
femoral n (L2, 3)
sartorius action
- hip – flex, ER, ABD
- knee – flex
describe the force chain of the quadriceps femoris
quadriceps muscles→ quadriceps tendon→ patella→ tibia/tibial tuberosity
rectus femoris prox attachment
ilium/AIIS
rectus femoris distal attachment
quadriceps tendon/patella/patellar ligament/tibial tuberosity
rectus femoris innervation
femoral nerve (L2, 3, 4)
rectus femoris action
- hip - flex femur
- knee - extend tibia
vastus lateralis prox attachment
femur
vastus lateralis distal attachment
quadriceps tendon/patella/patellar ligament/tibial tuberosity
vastus lateralis innervation
femoral nerve (L2, 3, 4)
vastus lateralis action
- extend leg at knee
- help stabilize patella at the knee
what part of the vastus lateralis stabilizes the knee?
vastus lateralis oblique = lateral retinaculum
vastus medialis prox attachment
femur
vastus medialis distal attachment
quadriceps tendon/patella/patellar ligament/tibial tuberosity
