High Yield Thigh and Patella Flashcards
What are the surfaces and borders of the femoral neck?
Anterior and Posterior surfaces
Superior and inferior borders
Which surface of the neck of the femur lies completely within the capsule of the hip joint?
The anterior surface of the neck of the femur.
Which intertrochanteric line is continuous with the sporal line?
The anterior surface/ intertrochanteric line.
The tendon of the …. borders the inferior portion of the posterior surface of the femoral neck.
Tendon of the obturator externus.
What are the surfaces and borders of the greater trochanter?
Lateral and medial surfaces (Lateral surface larger)
Borders: Superior, inferior, anterior and posterior.
Which tendon inserts into the trochanteric fossa?
The tendon to the obturator externus.
The tendon of the obturator internus attaches anterior to the trochanteric fossa.
Where do the superior and inferior gemelli terminate?
These guys terminate by entering the tendon of the obturator Internus.
What is the only border of the greater trochanter that does not have a muscular attachment?
The posterior border of the femor
The anterior border has the gluteus minimus
Posterior border has the gluteus medius
What is the only structure that inserts onto the lesser trochanter?
The iliopsoas.
Psoas major inserts at apex.
Iliacus insrts at base between spiral and pectineal lines.
What are the surfaces and borders of the femoral shaft?
Surfaces: Medial (Medial and posterior)
lateral (Lateral and Posterior)
anterior (Medial and Lateral)
Borders: Medial, Posterior, Lateral.
What are the three proximal portions that make up the linea aspera?
The spiral line medially
The Pectineal line intermediately
Gluteal tuberosity is the lateral line.
What attaches to the spiral line?
The vastus medialis
What inserts into the gluteal tuberosity laterally?
The gluteus maximus.
What originiates between the adductor magnus and the vastus lateralus muscles?
Gluteus maximus inserts proximally
The short head of the biceps femoris inserts inferiorly
Which muscles insert between the attachments of the adductor magnus and the vastus medialis?
Superiorly iliacus and pectineus muscles
Adductor brevis more supperior than adductor longus.
What are the two muscles of the anterior surface of the femur?
The vastus intermedialis
Articularis Genu muscle
What serves to separate the patellar and tibial surfaces of the femoral condyles?
The sulci menisci.
Where is the tendon of the popliteus muscle found when the knee is flexed vs when the knee is extended?
When the knee is flexed it is in the oblique groove
When the knee is extended it is in the vertical groove
Where does the nutrient artery to the femur come from?
Comes from the second perforating artery of the leg.
For all bones on the body the nutrient foramen is directed?
Away from the growing side of the bone in the body.
What type of ossification does the femur undergoe and how many ossification centers does it have
the femur undergoes endochondral ossification and has 5 ossification centers.
Where is the primary fusion center in the femur?
The shaft of the femur is the primary fusion center.
What are the surfaces and borders of the patella
Borders are superior, medial and lateral.
Surfaces are anterior and posterior.
Where does the patella receive blood supply?
From the genicular arteries that supply the quadriceps tendon.
Artery enters at the nutrient foramen in the lower 1/5th posterior surface.
