ossificatoin of the ADDuctor tendons due to chronic irritation, inflammation
Origin / Insertion of ADDuctor Longus / Brevis?
Pubis => linea aspera (of femur)
INN of ADDUctor brevis / longs?

damage to the obturator nerve would impair what lower limb movement?
what is Pes anserinus?
Goose foot = attachment of the sartorius, gracilis, and Semitendinosus tendons on the inferior medial side of knee joint on the tibia.
what supplies the anterior thigh?
the lateral circumflex femoral artery (which comes from the deep femoral which came from the femoral)
where is the femoral sheath located?
it is a funnel-shaped fascia tube that passes deep to the inguinal canal
Does the femoral Nerve pass within the femoral sheath?!
no it is lateral to the sheath
What are the compartments of the femoral sheath?
Femoral canal, femoral vein and femoral artery (medial to lateral)
what is inside the femoral canal?
It contains fat, lymph vessels, and nodes
What are the boundaries of the femoral triangle?
Inguinal Ligament (superior), ADDuctor longus (medial), and Sartorius (lateral) and fascia lata (Roof)
What are the contents of the femoral triangle?
Femoral N. and its branches, femoral sheath and its contents (femoral artery, vein, femoral canal)
What makes the floor of the femoral triangle?
(lateral to medial) iliacus, Psoas major, and pectineus
via catheterization the femoral ARTERY is used to reach what?
left side of the heart
via catheterization the femoral VEIN is used to reach what?
right side of the heart
Boundaries of Adductor Canal?
Vastus Medialis (laterally) Sartorius (medially / roof) and Adductor longus / Adductor Magnus (posterior)
Contents of Adductor canal?
femoraly artery and vein, saphenous nerve, nerve to vastus medialis muscle
Where / what is a Femoral Hernia?
is a loop of small intestines that protrudes (herniates) through the femoral canal; it occurs inferior to the inguinal ligament
What are the boundaries of the popliteal fossa?
semimembranosus, semitendinosus, gastrocnemius medial head, gastrocnemius lateral head, biceps femoris
contents of the popliteal fossa?
tibial nerve, popliteal vein (continuation of femoral), popliteal artery, common peroneal nerve (common fibular)
Muscles of lateral compartment of the leg?
Fibularis Longus and Brevis
Origin / Insertio of fibularis longus and brevis?
arise from the fibula, tendons run posterior to lateral malleolus ==> longus crosses and attaches to 1st metatarsal (in front of big toe) and brevis attaches to tuberosity on the base of the 5th metatarsal
INN of the lateral compartment?
Superficial fibular N.
Action of lateral compartment?
eversion of foot
Blood supply to the lateral compartment?
perforating branches of the anterior tibial artery proximally and from the fibular artery distally
Where is the common fibular nerve prone to injury?
it wraps itself around the head of the fibula, and is prone to injury there!
what does the common fibular nerve become?
superficial fibular nerve (which goes to lateral compartment) and the deep fibular nerve (which goes to anterior compartment)
muscles of the anterior leg compartment?
Tibialis anterior, extensor hallucis longus, extensor digitorum longus, fibularis (peroneus) tertius
INN of the anterior leg compartment muscles?
deep fibular nerve
which muscles it he most powerful dorsiflexor and everter of the foot?
tibialis anterior
what retinaculum restrains the tendons of the muscles of the anterior compartment of the leg?
the extensor retinacula
What forms the plantar arch of the foot (blood supply)?
it is an anastomoses between the lateral plantar artery (from posterior tibial) and dorsalis pedis (anterior tibial)
What would cause "foot drop"?
this would be due to injury to the common fibular nerve; because there is inability to dorsiflex and evert the foot.
what are the muscles of the superficial posterior leg compartment?
Gastrocnemius (medial + lateral heads), Soleus, and plantaris
INN of posterior leg compartment?
Tibial N.
what muscles are in the deep posterior compartment?
popiteus muscle, flexor digitorum longus, tibialis posterior, and flexor hallucis longus
what is the action of the popliteus muscle?
"unlocks" the knee via rotating the femur laterally on the fixed tibia
