Amputations Flashcards
(68 cards)
Limb salvage vs. amputation
severity scores are used by a healthcare team to make decisions
- mangled extremity severity score, limb salvage index, nerve injury, ischemia, soft tissue injury, skeletal injury, shock, age of patient score
What are some considerations for salvage vs. amputation?
- boundaries of dead tissue or diseased tissue
- consideration for prosthesis
- mobility and function
- cosmesis (aesthetic appearance)
Myodesis
the muscle is secured to bone by the distal tendon through holes drilled in the bone
Myoplasty
attaching sectioned muscles to opposing muscles
Minor amputation
toe and partial foot amputations
Major amputation
proximal to tarsometatarsal joint
What happens when someone looses an ankle joint?
- loss of somatosensory input
- reduced weight bearing through residual limb
- reduced confidence
- limitations with ADLs
- higher fall risk
- limits of stability is reduced in the residual limb compared to healthy individuals
- lack of kinesthetic awareness increases response time to adjust surface changes
Partial foot amputation
transmetatarsal
- maintains ankle integrity
What is another word for ankle disarticulation?
syme’s
What are the 2 main things to look at for return to function?
- prosthetic device
- standard shoe wear
Gait characteristics for LLA (lower limb amputation)
- loss of power generation
BKA
also known as transtibial
- 20-50% of tibial length is spared
- preserves the knee
LE problems seen with a BKA
loss of muscular control of lower limb muscle groups and foot/ankle
Knee disarticulation
femur remains completely intact
Gait characteristics seen with BKA
- decreased velocity
- shorter step length
- increased stance phase on sound limb
- decreased stance phase on amputated limb
- asymmetrical stance phase duration
AKA
also known as transfemoral
- 35-60% of femur length is spared
- preserves hip joint
- loss of joints below and impaired musculature below pelvis
What is the energy expenditure for walking with an AKA?
it increases to 60-65% vs normal walking
Gait characteristics seen with AKA
- lateral trunk lean during stance (trunk bends toward the prosthetic side)
- widened BOS
- circumduction
- abducted gait (prosthetic laterally displaced)
- uneven step length
- exaggerated lordosis
BE (below the elbow)
also known as transradial
- >80% of UE amputation are a result of trauma
- common in men 15-45 yrs
- cancer/tumor
- increased risk 65+
AE (above the elbow)
also known as transhumeral
Elbow disarticulation
through the elbow joint
Shoulder disarticulation
entire upper limb through the shoulder joint
Wrist disarticulation
through wrist joint removing carpal bones
Amputation rehab phases
- pre operative
- amputation with surgical reconstruction
- acute post operative
- pre prosthetic
- prosthetic prescription and fabrication
- prosthetic training
- community reintegration
- vocational rehab
- functional follow up
