Flashcards in Revision of the Lower Limb Anatomy Deck (74)
What is Shenton's line?
An imaginary curved line drawn along the inferior border of the superior pubic ramus (superior border of the obturator foramen) and along the inferomedial border of the neck of femur. This line should be continuous and smooth.
Name four ligaments at the hip joint
Ligamentum teres (inside joint capsule)
Which artery supplies the head of the femur?
Acetabular branch of the obturator artery
What's the blood supply to the neck of the femur?
Medial circumflex femoral artery (a branch off profunda femoris)
What are the three main arteries that supply the head and neck of the femur?
Acetabular branch of obturator artery, lateral and medial circumflex arteries (from deep femoral artery)
Name two ligaments of the pelvis
Sacrospinous and sacrotuberous ligaments
Where does gluteus maximus lie in relation to gluteus medium and minimum?
In front of
What is the primary function of gluteus maximus?
Hip extensor and lateral rotator
Where does the iliotibial tract insert?
Anterolateral tubercle of the tibia
What are the insertion points of the gluteus maximus muscle?
3/4 insets into the IT band and 1/4 insets into the gluteal tuberosity of the femur
Where is the tensor fascia latae muscle located?
Lateral anterior thigh above the IT band
What is the nerve supply to the lateral rotators of the hip?
What are the lateral rotators of the hip?
Piriformis, superior gemelli, inferior gemelli, obturator interns and quadratus femoris
What muscles are innervated by the superior gluteal nerve?
Gluteus medius, gluteus minimus and tensor fascia latae
What muscle is innervated by the inferior gluteal nerve?
What muscles does the anterior compartment of the thigh contain?
Quadriceps (+iliopsoas and sartortius)
What is the nerve supply to the anterior compartment of the thigh (quadriceps)?
The femoral nerve L2-L4
What is the function of the anterior compartment of the thigh (quadriceps)?
Flex hip and extend the knee
What muscles does the medial compartment of the thigh contain?
What is the nerve supply to the medial compartment of the thigh (hip adductors)
The obturator nerve (L2-L4)
Which muscles make up the quadriceps?
Vastus medialis, vastus lateralis, vastus intermedius and rectus femoris
What is the function of the medial compartment of the thigh?
What muscles does the posterior compartment of the thigh contain?
What is the nerve supply to the posterior compartment of the thigh (hip adductors)
Tibial branch of the sciatic nerve (L5-S2)
What is the function of the posterior compartment of the thigh?
Hip extension and knee flexion
What is the function of iliopsoas muscle and where is it found?
It consists of iliacus (on the ilium) and psoas major (from lumbar spine into neck of femur). It's the major flexor of the hip joint
What is the major flexor of the hip joint?
What is the function of sartorius and where is it found?
Goes from ASIS to medial knee (long and thin on a diagonall). It works to flex the hip and knee
What is the origin and attachment of the hamstrings?
All originate at the ischial tuberosity and attach distally to the tibia so act to flex the knee joint
