Ligaments And Articular Capsules 1

Question 1

What are the three extracapsular ligaments of the hip?

Answer 1

Iliofemoral ligament, pubofemoral ligament, ischiofemoral ligament

Question 2

What are the intracapsular ligaments of the hip?

Answer 2

Transverse acetabular ligament, labrum of the acetabulum, zona orbicularis, ligamentum teres

Question 3

What is a posterior dislocation of the hip?

Answer 3

The head of the femur is driven posteriorly out of hte acetabulum, causing it to look flexed, internally rotated and adducted

Question 4

What two bones does the fibular/lateral collateral ligament attach to?

Answer 4

Fibula and femur

Question 5

What two bones does the anterolateral ligament attach? What does this ligament do?

Answer 5

The anterolateral tibia and lateral epicondyle of the femur

Prevents excessive internal rotation of the tibia

Question 6

Where does the tibial/medial collateral ligament attach (MCL)?

Answer 6

Medial epicondyle of the femur and medial surface of tibia; it also connects the medial meniscus

Question 7

Where does oblique popliteal ligament attach?

Answer 7

Lateral femoral condyle to the medial tibial condyle (runs obliquely)

Question 8

Where does the arcuate popliteal ligament attach?

Answer 8

lateral femoral condyle and lateral fibular head to the fibrous capsule of knee joint

Question 9

Where does the anterior cruciate ligament attach? What is its function?

Answer 9

Posteromedial surface of the lateral femoral condyle from the anterior intercondylar area of the tibia

Limit posterior rolling of the femoral condyles on the tibial plateau during flexion and Prevent hyperextension of the knee

Question 10

Where does the posterior cruciate ligament attach? What is its function?

Answer 10

Anterolateral surface of medial femoral condyle from the posterior intercondylar area of tibia

Prevents femur from going anterior when you flex knee

Question 11

Where do the medial and lateral menisci sit? What do they do? What ligament connects them across the knee?

Answer 11

Between the medial condyle of femur and medial tibial condyle (medial) and the lateral condyle of femur and lateral tibial condyle (lateral)

Absorb shock and stress

The transverse ligament of the knee

Question 12

What’s the unhappy triad?

Answer 12

Tearing of the ACL, MCL, and medial meniscus while knee is fully extended

Question 13

What are the two retinacula of the foot?

Answer 13

Superior extensor retinaculum and inferior extensor retinaculum

Theres also a plantar aponeurosis

Question 14

What two ligaments connect the fibula and talus? Which one tears more commonly?

Answer 14

Anterior talofibular L and posterior talofibular L

The anterior talofibular L

Question 15

What ligament attaches the fibula with the calcaneus ?

Answer 15

Calcaneofibular L

Question 16

What four parts make up the deltoid L?

Answer 16

Anterior tibiotalar part

Tibionavicular part

Tibiocalcaneal part

Posterior tibiotalar part

Question 17

What is the Pott’s fracture dislocation?

Answer 17

A fracture in the medial malleolus, separating the talus and causing a fracture in the distal fibula, tearing the anterior tibiofibular L

Question 18

What are the arch support ligaments?

Answer 18

Tendon of fibularis longus, long plantar ligament, tibialis posterior, plantar calcaneocuboid L, plantar calcaneonavicular L

Question 19

What is Pes Planus?

Answer 19

Flat foot; the arch of the foot is fallen

Question 20

Where does the ischiofemoral L attach?

Answer 20

Ichial part of acetabular rim and attach medial to the greater trochanter

Question 21

What does the zona orbicularis support?

Answer 21

The neck of the femur

Question 22

What does the acetabular labrum do?

Answer 22

Creates a deeper socket for the femoral head to sit inside

Question 23

What does the ligamentum teres do and where does it attach?

Answer 23

It houses the obturator artery in earlier stages of life

The fovea of the head of the femur to the acetabulum

Question 24

What does the valgus test test for?

Answer 24

Testing the medial collateral ligament

Question 25

What does the varus stress test test for?

Answer 25

The strength of the lateral collateral ligament

Question 26

What is the Lachman’s test?

Answer 26

It tests for the ACL and PCL, pushing anteriorly tests ACL and pushing posteriorly tests PCL

Question 27

What is McMurray’s test?

Answer 27

Tests the meniscus

Testing for the lateral meniscus by putting pressure on it (push from lateral to medial on proximal tibia and pull medial to lateral on distal tibia)

Testing the medial meniscus is just the opposite

Question 28

What’s the apley grind test?

Answer 28

With patient prone, flex knee to 90 degrees, push down and compress knee joint, internally and externally rotate to see if they’re pain

If there is, that is indicative of pathology

Question 29

What are the three arches of the foot? What is the purpose?

Answer 29

Medial longitudinal, lateral longitudinal and transverse arch

To absorb shock and make the foot adaptable to different surfaces

Question 30

What makes up the dynamic support of the foot?

Answer 30

Intrinsic foot muscles and tendons of fibularis longus and tibialis posterior

Question 31

What makes up the passive support of the foot?

Answer 31

Plantar aponeurosis

Long plantar ligament

Short plantar ligament

Spring ligament (transfers weight from talus to rest of foot)
