Lecture 15 - Amputations Flashcards
What are common causes of limb loss
Residual limb
Remaining part of limb after an amputation
Remaining Limb
Unaffected leg
Amputation
Loss or removal of a portion or entire limb by dividing through one or more bones
Disarticulation
Removal of a limb between joint surfaces
Partial Toe (Amputation)
Ray Resection (Amputation)
Trans metatarsal (Amputation)
Ankle Disarticulation (Symes -> Amputation)
Transtibial (BKA -> Amputation)
Transfemoral (AKA -> Amputation)
Hip Disarticulation (Amputation)
Hemipelvectomy (Amputation)
Hemicorporectomy (Amputation)
What are the 2 most common LE amputations?
Circled in red
Compare transtibial (BKA) and Syme’s (Ankle disarticulation) amputation in terms of lever length, shape, healing rate, and end weightbearing
Note: Cylindrical is better for prosthesis
Name some UE amputation
What is a forequarter (interscapulothoracic) amputation
Amputation that is very rarely performed (only malignancies) that takes the entire UE including scapula and clavicle
Osseointegration
Metal implant that attaches to femur that prevents rubbing and irritation on butt and groin area = much more comfortable and can feel the ground and vibrations
Rotationplasty
Cut off bad part of leg (most of it) and rotate foot/ankle and reattach to upper thigh, then can attach prosthetic to foot and gives them the benefit of it being easier for a prosthetic and for them to keep their sensation in their foot
Open amputation
Wound left open to allow for clearance of infection
NOTE: Black dressing = put over open wound hooked up with hose to portable vacuum to stimulate granulate tissue to help with healing
Closed amputation
Skin flaps are closed
What factors determine the level of amputation
- Patient history
- surgeons clinical exam
- Surgeon’s knowledge/preference
- Interoperative tissue condition
- Tissue viability
- Infection
- Function
What are 3 surgical goals of amputation
What are 4 methods of muscle closure after amputation
What happens to the skin after amputation
What happens to the bone after amputation
What happens to the nerves after amputation
What happens to the blood vessels after amputation
