amputations Flashcards
(37 cards)
amputations
congenital, peripheral, vascular disease, trauma, cancer, infection
body powered prosthesis
uses specific muscles to place tension on the cable that opens or closes the terminal device
two main types of body operated TDs
hook and the prosthetic hands
voluntary closing (VC)
hook remains closed until tension is placed on cable and then it closes
voluntary opening (VO)
hook remains closed until tension is placed on the cable and then it opens
- prescribed more than the VC
Hook TDs
used to perform functional activities
hook with slanted fingertip
easier for the used to see during functional tasks
a lyre shape hook
allows for a cylindrical grasp
aluminum hook
less weight, used mainly for lighter functional tasks
stainless steel hook
sturdier, better for heavier outdoor work
hand TDs
used for cosmetic appearance and have limited pinch force
transradial prosthesis of body powered
uses humeral flexion and scapular abduction
transhumeral prosthesis of body powered
uses humeral flexion and scapular abduction and scapular depression, shoulder extension, and abduction to lock and unlock elbow
shoulder disarticulation of body powered
chest expansion to control
myoelectric (electrically powered) prosthesis
- muscle contractions of 2 different muscle groups are used to control the TD
- hook and hand
electric hook
allows for pinch and fine motor manipulation
sensor hand electric
open and close and has 3 point pinch
multi-articulating hand electric
have multiple grasp patterns that allow for increased functional use
transradial prosthesis of electric
uses wrist flexors and extensors
transhumeral prosthesis of electric
uses biceps and triceps
shoulder disarticulation of electric
uses pectoralis major or infraspinatus
hybrid prostheses
combination of body powered and electrical powered
- most common for elbow or above elbow amputations
passive prosthesis: static
- used for cosmetic appearance; can be passively adjusted to assist with carrying and grasping
activity specific prosthesis
- no harness or control cable
- designed to be used for specific work and leisure tasks
- can be used interchangeably with a body powered or myoelectric prosthesis
