Chapter 5: Lower Limb (Continued) Flashcards
What is the femoral triangle bounded by?
inguinal ligament, and the sartorius and adductor longus muscles.
What is within the femoral triangle?
femoral sheath (containing the femoral artery and vein and canal) and femoral nerve (which is outside of the femoral sheath)
List the structures lateral to medial passing under the inguinal ligament .
femoral nerve, femoral artery, femoral vein, an empty space within the femoral sheath called the femoral canal, and inguinal lymph nodes within the femoral canal (NAVEL)
The fibrous capsule of the hip joint is reinforced by what ligamentous thickenings?
iliofemoral ligament, ischiofemoral ligament, and pubofemoral ligament
The knee joint is a synovial joint formed by what articulations?
medial and lateral femoral condyles, and the medial and lateral tibial condyles and the patella
What does the tibial collateral ligament extend from?
the medial epicondyle of the femur inferiorly to attached to medial aspect of the tibia
The tibial collateral ligament is firmly attached to which meniscus, medial or lateral?
medial meniscus
The tibial ligament prevents lateral or medial displacement of tibia under the femur?
lateral displacement (abduction) of the tibia under the femur
Where is the fibular collateral ligament located?
extends from the lateral condyle of the femur inferiorly to attach to the head of the fibula
Is the lateral collateral ligament attached to the lateral meniscus?
no
Which is the most torn ligament of the knee?
tibial collateral ligament
What are the tests that test the inegrity of the anterior and posterior cruciate ligaments?
anterior and posterior drawer signs
What occurs with tearing of the anterior cruciate ligament
allows tibia to be easily pulled forward (anterior drawer sign)
Tearing of the PCL allows for what?
tibia to be easily pulled posteriorly (posterior drawer sign)
What are the 3 most commonly injured structures of the knee?
tibial collateral ligament, medial meniscus, and the ACL (the unhappy triad)
