Lower Extremities- Bones & Joints

Question 1

Coxofemroal joint capsule surrounds what bone?

Answer 1

Femur

Question 2

Where does coxofemoral joint capsule attach to?

Answer 2

Acetabulum- this creates the ball-and-socket function of the hip

Question 3

What three ligaments stabilize the hip joint?

Answer 3

Iliofemoral
Pubofemoral
Ischiofemoral

Question 4

Iliofermoral ligament goes from which two places?

Answer 4

Ilium -> Anterior femur

Question 5

Pubofemroal ligament goes from which two places?

Answer 5

Superior public ramus -> femoral neck

Question 6

Ischiofemoral ligament is around what?

Answer 6

From the posterior acetabulum around the neck of the femur

Question 7

What causes anterior hip dislocations?

Answer 7

The weak spot between the iliofemoral and pubofemoral ligaments

Question 8

What causes posterior hip dislocations?

Answer 8

Weak spot between iliofemoral and ischiofemoral ligaments

Question 9

What four ligaments stabilize the knee joint?

Answer 9

Lateral (fibular) collateral
Medial (tibial) collateral
Anterior cruciate ligament
Posterior cruciate ligament

Question 10

The medial meniscus attaches to what?

Answer 10

Medial collateral ligament

Question 11

Is the lateral meniscus attached to the lateral collateral ligament?

Answer 11

Lateral collateral ligament

Question 12

What does the anterior cruciate ligament help prevent?

Answer 12

Helps prevent anterior translation of tibia

Question 13

What does posterior cruciate ligament help prevent?

Answer 13

Helps prevent posterior translation of tibia

Question 14

True/False: The anterior&posterior cruciate ligaments are INSIDE the synovial joint of the knee

Answer 14

FALSE

Question 15

When someone injures their knee, is it more common for them to injure more than one structure?

Answer 15

Yes!

Question 16

Varus means what?

Answer 16

abnormal medial orientation of segment

“bowlegged”

Question 17

Valgus means what?

Answer 17

abnormal lateral orientation of segment

“knock-kneed”

Question 18

What is bursitis?

Answer 18

Irritation or infection of the bursae

Question 19

Popliteal (Baker’s) Cyst

Answer 19

Joint effusions can sometime push the synovial lining out of the posterior aspect of the fibrous joint capsule and create a synovial swelling in the popliteal fossa

Question 20

Where do the tibia and finula interact?

Answer 20

Superiorly- Tibiofibular joing

Along their lengh- Interosseous membrane

Inferiorly- tibiofibular syndemosis

Question 21

Tibiofibular syndesmosis consists of what two ligaments?

Answer 21

Anterior and Posterior inferior tibiofibular ligaments

Question 22

High ankle sprain is a disruption of what?

Answer 22

Tibiofibular syndesmosis

Question 23

What ligaments stabilize the ankle joint?

Answer 23

Deltoid ligament (medial)
Anterior talofibular (lateral)
Calcaneofibular (lateral)
Posterior talofibular (lateral)

Question 24

What three ligaments stabilize the lateral aspect of the ankle?

Answer 24

Anterior talofibular

Calcaneofibular

Posterior talofibular

Question 25

Why are inversion (varus) sprains more common than eversions (valgus) sprains?

Answer 25

Because the medial malleolus is shorter than the lateral malleolus

Question 26

What does the deltoid ligament connect?

Answer 26

Medial malleolus -> tarsal bones

Question 27

What is a Pott’s fracture

Answer 27

Fracture of the distal fibula

Question 28

What joints in the foot are responsible for foot inversion and eversion

Answer 28

Subtalar and transverse tarsal joints
