27
Q

What are the static support structures of the hip?

28
Q

Labrum

  • Composed of?
  • Function?
  • What structure is shown by the arrow in the image below? What is its function?
A
  • Fibrocartilage
  • Increase the depth of the socket, protect edges of labrum, create negative pressure to keep head of femur in socket
  • Transverse acetabular ligament; close off labrum b/c labrum is not full circle
29
Q
  • What ligaments are shown by the green arrows?
  • What are their functions?
    *
A

Additionally, pubofemoral ligament also helps prevent anterior dislocation of head of femur

30
Q

What ligament is shown by the green arrow?

What is its function?

31
Q

What ligament is shown by the green arrow?

What is its function?

A

Ligamentum capitis femoris

Maintain the position of the head of the femur in the acetabulum, in some people it also contains an artery (branch of obturator artery) that supplies blood to head of femur

32
Q

The medial and lateral femoral circumflex arteries arise from the […] artery.

A

Deep femoral

33
Q

The anatomical axis of the tibiofemoral joint is […] degrees off the mechanical axis (which is a straight vertical line).

A

6 –> 6 degrees of valgus relative to mechanical axis

34
Q

The anatomical joint line of the tibiofemoral jiont is […] degrees off from the mechanical axis (straight horizontal line through the top of the tibia).

A

3 degrees –> 3 degrees of varus deviation from mechanical axis

35
Q

What does it mean to say that a person has a valgus knee?

36
Q

What does it mean to say that a person has a varus knee?

37
Q

What is the difference between closed and open chain movements?

A

Closed chain - limb is supported by structure at one end

38
Q

What is the difference between osteokinematics and arthokinematics?

A

Osteo - relative movement between two bony segments (i.e. femur and tibia)

Artho - movement of individual components of a joint (see image, when we go from sitting to standing we don’t just have extension of femur, individual end of femur moves in the joint space to achieve proper alignment)

39
Q

What is closed vs. open packed positioning (arthokinematics)?

40
Q

What are the 3 articulating surfaces of the knee joint?

41
Q

What is the function of the patella?

A

The patella increases the leverage that the quadriceps tendon can exert on the femur by increasing the angle at which it acts

42
Q

What structure is shown in blue?

A

Synovial membrane

43
Q

Medial Collateral Ligament

  • Origin and insertion?
  • Deep fibers attach to what structure in the knee joint?
  • What is its function?
  • How can it be tested in physical exam?
44
Q

Lateral Collateral Ligament

  • Origin and insertion?
  • Function?
  • How to test in physical exam?
46
Q

What is the function of the ACL and PCL?

47
Q

What are the functions of the menisci?

48
Q

How are the menisci attached to the knee?

49
Q

What is the function of the interosseous membrane in the lower leg?

50
Q

What are the functions of the foot/ankle?

51
Q
  • What type of joint is the talocrural joint?
  • What bones make up the joint?
  • What movements are possible?
  • Is this joint more stable in plantar or dorsiflexion?
52
Q
  • What are the static supports of the ankle?
  • Which are lateral? What motions do these ligaments resist?
  • Which are medial? What motions do these ligaments resist?
A
  • Lateral = anterior talofibular lig., posterior talofibular lig., and calcaneofibular lig. –> resist inversion
  • Medial = deltoid lig., resisits eversion
53
Q

Subtalar Joint

  • What type of joint is the subtalar joint?
  • What are the articulating surfaces of this joint?
  • What movements occur at this joint?
  • What are the static supports of this joint?
54
Q
  • What type of joint is the talocalcaneonavicular joint?
  • What is an important static support of this joint?
56
Q

Calcaneocuboid Joint

  • What type of joint is this?
A

Synovial, between anterior calcaneous and posterior cuboid

57
Q

The transverse tarsal joint is a (functional or structural) joint. It is the most […] joint of the foot. It allows foot to adapt to a variety of surfaces.

A

Functional

Versatile

58
Q
  • Label these structures
  • Why are they so important?
A

They are the primary loadbearing and shock absorbing structures of the foot

59
Q

What are the primary supports of the medial arch?

60
Q

What are the primary support structures for the lateral arch?

61
Q

What are the primary support structures for the transverse arch?
