16
Q

Why does the femur need to be as long as possible in a transfemoral amputation?

A
  • longer lever arm

- easier to control prosthetic limb

17
Q

What is a hip disarticulation?

A
  • still has a pelvis, but removes the entire leg

- salvage procedure

18
Q

prosthetics for his disarticulation

A

generally locked into knee extension

19
Q

What is a hemipelvectomy?

A

get rid of lower half of pelvis

20
Q

What is a hemicorporectomy?

A
  • get rid of entire pelvis
  • salvage procedure
  • some people born that way
21
Q

A

pelvic floor muscles have nothing to act on

22
Q

What condition is rotationoplasty often used for?

A

Ewing sarcoma

  • typically occurs in young males
  • bone cancer that presents in distal femur or proximal tibia during puberty
23
Q

What is rotationoplasty?

A
  • take the chunk out that’s bad
  • rotate foot 180˚
  • therapy to reach terminal extension
  • foot placement for prosthetic
24
Q

benefit of rotationplasty

A

get knee control, essential for gait (PF is now extension)

25
Q

UE amputations?

A

can have them, but we don’t see them as much
