Ant compartment of thigh II Flashcards
floor of fem triangle (2)
Iliopsoas
Pectineus
Contents of fem triangle
Femoral N Femoral A/ femoral branch Genitofemoral N Femoral V Deep ing lymph node
Borders of fem triangle
inguinal lig (sup) adductor longus sartorius
pathway of femoral artery
disappears at lower edge of fem triangle (covered by sartorius)
will enter abductor tunnel then travel to the post side of the knee
now called popliteal artery
what does the popliteal artery split into and what’s the path
Ant tibial artery–> dorsal pedis artery
Post tibial artery–> medial + lat plantar arteries
chief artery that supplies all muscles of thigh
deep femoral artery of thigh
how many perforating arteries come off of the femoral artery
4
perforate the medial group of muscles and hamstring
What 3 things does the deep femoral artery split into
perforating branches
lat circumflex
medial circumflex
what are the branches of the lat circumflex
- Ascending (greater trochanter)
- Transverse
- descending (goes as low as knee)
what are the branches of the medial circumflex
- acetabular
- ascending- blood supply for neck (astemoses w other ascending)
- transverse- escricles proximal femur (astemoses w other transverse)
how to find femoral artery pulse (what do u put your fingers on)
pinky on ASIS, thumb on pubic tubercle
pulse midpoint below inguinal lig
ant flexor compartment- what nerves, vessels, sc segment
femoral n
femoral vessels
Inv. L2, L3, L4
medial adductor compartment- what nerves, vessels, sc segment
Obturator n
Obturator vessels
Inv. L2, L3, L4
post extensor compartment- what nerves, vessels, sc seg
sciatic n
deep vessels of thigh
inv. L5, S1, S2
what is the only nerve that doesn’t innervate any structures of the ant thigh
saphenous nerve
deep tendon reflex of leg tests what nerve seg
femoral nerve
L2, 3, 4
what is chonramalacia due to
soreness around & deep to patella resulted from quad imbalance (vestus lateralis is more powerful)
Lat, med, Anterior walls of adductor canal
lat- vastus medialis
med- adductor longus +adductor magnus
Ant- Vasto-adductorial membrane + sartorius
sup opening contents of adductor canal
Femoral A
Femoral V
Nerve to vastus medialis
Saphenous N (L3, L4)
adductor cannal ant opening contents
saphenous n
descending genicular artery
saphenous n is deep to what muscle
sartorius
in saphenous n neuropathy what will be the areas of pain
Lower medial aspect of knee
Medial aspect of leg to ankle regions
dorsal medial side of foot
(no motor function loss)
where does a femoral hernia occur thru
bowel will displace lymph nodes and descend thru femoral canal to the saphenous opening
Inguinal hernias are located medial to what structure
Pubic tubercle
