Flashcards in Week 5 - Anterior Medial Thigh Deck (12)

Where does the Iliopsoas muscle insert? What is unique about this muscle?

It inserts on the lesser trochanter of the femur.
It is the strongest flexor the the hip joint. (it also internally rotates the femur)
-Innervated by the ventral rami or L1-L3


Which muscles extend the leg at the knee?

Sartorius, quadriceps femoris, iliopsoas
(hamstrings & glueus maximus do the opposite - they flex the knee and extend the thigh)


What type of hip fracture is most common in elderly females?

Subcapital (neck) fracture


Which of the following arteries is most important in contributing a blood supply to the head and neck of the femur?

Medial circumflex femoral artery


What nerve accompanies the great saphenous vein down the medial side of the leg?

Saphenous nerve!


What artery supplies the head of the femur in early childhood but not longer in older patients?

Obturator artery branch


Patient has painful right foot - thrombotic occlusion of the femoral artery in adductor canal.
What artery will most likely provide blood supply to the leg through the genicular anastomosis?

Descending branch of the lateral circumflex femoral artery


What are "groin pulls"?

Strains of the adductor muscles (stretching or tearing too)
-Often occur in quick start sports


What innervates the adductor magnus?

Tibial & obturator nerves


What does the limb look like in a femoral fracture?

Limb is laterally rotated and shorter due to muscle imbalances (gluteal rotator muscles)


What is the most common hip dislocation?

-Hip dislocation can be congenital or acquired (traumatic injuries)
-It causes the femur to be medially rotated & shorter (due to Psoas muscle spasm)


What is hip dysplasia?

Newborns are screened for it. Treatment requires a harness that keeps the hip joint in place while child grows - may require surgery
-It's a dislocation of the femoral head
