Flashcards in Lecture 8.1 Deck (39):
1

Which is the 'big' adductor?

magnus

2

The Gluteus medius and minimus help to do ___ _____ in addition to abduction

medial rotation

3

what are the fixators of the hip joint and what other movement do they produce?

Piriformis
Superior gemellus
obturator internus
inferior gemellus
quadrats femoris


also act as later rotators

4

Which nerve innervates the gluteus medius and minimus?

Superior Gluteal nerve

5

Which nerves supply the hip joint?

anteriorly - femoral
inferiorly - Obturator (ant. division)

Posteriorly - superior gluteal nerve to quadratus femors
sciatic

6

the hip may refer pain to the _____ becase

knee - it lies deeper to the knee and has same innervation

7

Which blood vessels (from the femoral artery) mainly supplies the hip joint?

medial and later circumflex arteries

8

The knee is a ___ joint

compound - more than two bones articulating

tibiofemoral and
patellofemoral

also a modified hinge joint
F/E and rotation

9

The knee is most stable in ______

extension


10

Why does the knee have poor bone congruence?

condyles are not the same size

shape of articulation - femur and tibia meet at an oblique angle

11

The articular capsule attaches at articular margins and _____

menisci

12

The two deficiencies in the knee capsule are from what anteriorly and posteriorly?

anterior: Suprapatella bursa

posterior: popliteal tendon

13

overuse of the joint can result in synovial ______

synovial effusion - rapid swelling

14

What is the name of the communication bursae deep to the patella?

suprapatella bursae

15

the vastus _______ has tiny fibres that attach to the suprapatella bursae and pull it out of the way in extension- to stop ______

the vastus intermedius has tiny fibres that attach to the suprapatella bursae and pull it out of the way in extension- to stop pinching

16

True or False

The subcutaneous prepatella bursae is non-communicating

true

Lies superficial to the patella

17

The ______ ______ bursae is prone to inflammation and infection

The subcutaneous infrapatella bursae is prone to inflammation

18

What are the exterior ligaments of the knee?

Ligamentum patellae

oblique popliteal ligament

Arcuate popliteal ligament

19

What are the intrinsic ligaments of the knee:

ACL/PCL

Transverse ligament - connect the menisci

20

The medial colateral ligament is _____

wider

21

The MCL attaches to the medial ____

meniscus

22

The MCL works with the ACL to stop the ____ moving too far forward

The MCL works with the ACL to stop the tibia moving too far forward

23

The lateral colateral Ligament is separated from lateral meniscus by _____tendon

popliteal tendon

24

Both the LCL and MCL are taut in _______

Extension

25

Cruciate ligaments stop excessive _____/_____ displacement

Cruciate ligaments stop excessive anterior/posterior displacement

26

The ACL is prone to injury in _____ and ______ knee

The ACL is prone to injury in flexed and rotated knee

27

The __ assists internal rotation of femur and contributed to locking

ACL

28

The PCL is taut in full ____

flexion

29

The mensici allow separate movements in the knee joint capsule

during rotation the menisci hug the ______ end of the femur

inferior

30

Ligament and meniscal damage is most common in ______ sports

twisting

31

The ______ muscle locks and unlocks the knee in conjunct rotation

Popliteus


"pops" the knee out and mobile

32

Adjunct is when your knee is flexed and can do internal and external rotation, which muscles allow this?

semitendinosus and Biceps femoris

33

The medial condyle is ______- which helps with the passive locking mechanism

longer

34

The femoral artery goes through the adductor ____

hiatus

35

The branches that supply the knee are called _____

genicular arteries

lots of them, lots of blood supply

36

If contact is with the lateral condyles of the knee it is called genu ____

valgum

37

The patella increases the pull of the ____ along the long axis of the lower limb - it makes contact with the ____ tuberosity (via patella ligament) at a ____angle = more leverage

The patella increases the pull of the quads along the long axis of the lower limb - it makes contact with the tibial tuberosity at a greater angle = more leverage

38

Due the oblique angle of the femur, the tendency is for the patella to be pulled ______

Due the oblique angle of the femur, the tendency is for the patella to be pulled laterally

39

What are the factors that prevent the patella from displacing laterally?

active contraction of vastus medialis

medial patella retinaculum

Raised lip on lateral femoral condyle (the lateral condyle of the femur has an anterior projection)
