Flashcards in Articulations: Selected Articulations in Depth Deck (37):
1

Name the 2 ligaments of the acromioclavicular joint

-acromioclavicular ligament
-coracoclavicular ligament

2

What helps to deepen the concavity of the glenoid cavity in the glenohumeral joint?

the glenoid labrum

3

Name the 4 major ligaments of the glenohumeral joint.

-coracoacromial ligament
-coracohumeral ligament
-glenohumeral ligaments
-transverse humeral ligament

4

injury that can occur from swinging young children by their arms

subluxation of the head of the radius from the anular ligament

5

what typically happens to the joint when a finger is "jammed"

joint dislocates posteriorly, where there is no ligamentous support

6

What part of the coxal joint is very similar to that of the glenohumeral joint?

the acetabular labrum

7

What is the largest and most complex diarthrosis of the body?

the knee joint

8

What is meant by varus deviation?

hyperadduction of the lower leg, part distal to the joint is abnormally angulated towards the midline of the body

9

ligament in knee that prevents varus deviation

LCL-lateral collateral ligament

10

collateral ligament that is NOT attached to the meniscus

LCL

11

collateral ligament that IS attached to the meniscus

MCL

12

ligament in knee that prevents valgus deviation

MCL-medial collateral ligament

13

What is meant by valgus deviation?

hyperabduction of the lower leg, part distal to the joint is abnormally angulated away from the midline of the body

14

stabilizing ligament on from surface of knee that prevents the knee from collapsing inward

ALL-anteriolateral ligament

15

C-shaped fibrocartilage pads located on the condyles of the tibia

medial meniscus and lateral mensicus

16

When the knee is extended, this cross-shaped ligament is pulled tight and prevents hyperextension

ACL-anterior cruciate ligament

17

When knee is flexed, this cross-shaped ligament is pulled tight and prevents hyperflexion

PCL-posterior cruciate ligament

18

tibia rotates laterally to tighten ACL and squeeze meniscus between tibia and femur. this accomplishes what?

locking the knee

19

what ligament is frequently torn in knee dislocations?

ACL

20

transplantation of tissue from person who is genetically different

allograft

21

tissue transplant from one site on a person to a different site on the same person

autograft

22

tissue transplant from genetically identical person

syngenetic graft/isograft

23

tissue transplant from an animal into a human

heterograft/xenograft

24

stretching or tearing of ligaments without fracture or dislocation of the joint

sprain

25

what may result from an overeversion sprain?

a Pott fracture

26

when the posterior talar process appears a separate ossicle in an adult and they suffer a traumatic event

os trigonum syndrome

27

high ankle sprain/ disruption of interosseous membrane that holds distal ends of tibia and fibula together

syndesmotic ankle sprain

28

movement of plantar surface (sole) medially

inversion

29

movement of plantar surface (sole) laterally

eversion

30

ligament on medial side of talocrural joint that is incredibly strong and rarely tears

deltoid ligament

31

ligaments on the lateral side of the talocrural joint and where they pass relative to the malleolus of the fibula

-anterior talofibular ligament (anteriorly)
-posterior talofibular ligament (posteriorly)
-calcaneofibular (lateral) ligament (inferiorly)

32

most common cause of ankle sprains

excessive inversion

33

what is a "nutcracker injury"

os trigonum and surrounding soft tissue is crunched between the calcaneus and the talus and tibia (like and almond in a nutcracker). can lead to inflammation

34

surgical joint replacement

arthroplasty

35

What joint replacement surgery has the shortest recovery time? longest?

shortest is total knee, longest is total shoulder

36

What other ligament of the knee joint is commonly injured by the same forces that would injure the ALL?

ACL

37

What other ligament of the knee joint is commonly injured by the same forces that would injure the medial meniscus?

MCL
