Q

What makes up the midtarsal joint

A

Talonavicular and calcaneal cuboid joints

43
Q

What is a syme amputation

A

Ankle disarticulation where the heel pad is kept for distal end weight bearing and the tibia and fibula ends may be shaved to create a narrow end

44
Q

True or False:

With a syme amputation you have the potential to ambulate with and without a prosthesis

A

True

45
Q

What is a transtibial amputation

A

Amputation across the tibia and fibula

46

1-2 cm

47
Q

True or False:

The anterior surface of the tibia is beveled

A

True

48
Q

Where is the surgical closure for a transtibial amputation

A

Anterior

49
Q

What are the 4 types of transtibial amputations

A
  1. Very short
  2. Short
  3. Standard
  4. Long
50
Q

What is a short/very short transtibial amputation

A

Less than 20% of the tibial length remains

51
Q

Where does a very short transtibial amputation transect

A

The tibial plateau

52
Q

True or False:
You may choose a knee disarticulation over a very short/short transtibial amputation due to the shorter lever arm making control of the knee difficult

A

True

53
Q

What is a standard transtibial amputation

A

20-50% of the tibial length remains

54
Q

What is a long transtibial amputation

A

Greater than 50% of the tibial lengthen is present

55
Q

True or False:

A patient with a long transtibial amputation may have problems with distal limb circulation

A

True

56
Q

What is a knee disarticulation

A

The tibia and fibula are removed the patella and patellar tendon are saved

57
Q

What is done with the patellar tendon and hamstrings in a knee disarticulation

A

They are attached to the cruciate ligaments and up through the bone

58
Q

True or False:

Knee disarticulation provides good weight bearing surface and long lever arm

A

True

59
Q

True or False:

Cosmesis of the socket is a disadvantage with a knee disarticulation

A

True

60
Q

Why is cosmesis of the socket a disadvantage with a knee disarticulation (2)

A
  1. Femoral condyles being wider so prosthetics must be wider

True or False:

Adequate healing may be a problem with transfemoral amputation

A

True

66
Q

What is a long transfemoral amputation

Greater than 60% of the femur length is present

67
Q

True or False:

There is no distal end bearing with a long transfemoral amputation

A

True

68
Q

What is a medium or standard transfemoral amputation

A

35-60% of the femur length is present

69
Q

True or False:

With a medium or standard transfemoral amputation a myodesis and myoplasty technique are both used at the distal end

What is a short transfemoral amputation

A

Less than 35% of the femoral length is present

71

Where can a short transfemoral amputation be transected up to

A

The lesser trochanter

72

What is a hip disarticulation

A

Removal of all of the femur

Loss of the LE including any part of the ilium, ischium, or pubis

74
Q

What are common post-op complications (6)

A
  1. Phantom limb pain/sensation
  2. Death
  3. Pulmonary problems/pneumonia
  4. Non healing residual limb
  5. Infection of residual limb
  6. Pulmonary embolus
75
Q

What are common early phase complications (5)

A
  1. Infection
  2. Delayed wound healing
  3. Painful residual limb
  4. Phantom sensations
  5. Pressure sores
76
Q

What are common late phase complications (3)

A
  1. Phantom limb pain
  2. Flexion contractures
  3. Gangrene
77
Q

What are the 2 primary goals of the immediate post-op period

A
  1. Ensure optimal wound healing

2. Early preparation of the limb for prosthetic fitting

78
Q

What are the 3 IPOP steps

A
  1. Application of padding (prep site for prosthetic unit)
  2. Application of rigid dressing
  3. Incorporate prosthetic system
79
Q

What is the rigid dressing

A

Like a cast the provides compression over the pad and allows for earlier WB and decreased swelling

80
Q

What is a risk of the rigid dressing

A

You can’t see the surgical sight

81
Q

What does the rigid dressing need attachments for

A

Pylon and foot

82
Q

What are the 4 factors that influence optimal rehabilitation

A
  1. Level of amputation
  2. Skill of surgical team, shaping optimal limb, and optimal healing
  3. Appropriate post-op care/follow up
