Novel Surgical Procedures & High-Level Prosthetic Devices Flashcards
what are the possible complications of femoral lengthening after TFA?
infection
slowed bone healing
pin migration
what improvements are seen after femoral lengthening after TFA?
gait
lower energy consumption
patient satisfaction
prosthetic use
femoral lengthening commonly lengthens the femur from ____ to ____ cm
15.5 cm to 21 cm
what are advantages to osseointegration?
removed socket-residual limb interface
improved function
improved quality of life
what are disadvantages of osseointegration?
risk of infection/irritation
risk for revised amputation in case of falls with fracture
what happens during an ewing amputation?
agonist-antagonist myoneural interface (AMIs) are created by linking muscle pairs within the residual limb (connects agonist and antagonist muscles)
what is the purpose of an ewing amputation?
aimed to provide proprioceptive feedback and better control of prosthetic device
– embodiment –> feels more connected with their foot
who were intrepid dynamic exoskeletal orthosis (IDEO) originally developed for?
service members with severe lower limb trauma (fractures, nerve injury, arthritis, ankle fusion)
what kind of material is the IDEO?
custom carbon fiber AFO
what does the IDEO improve?
pain
general LE function
high-level function
in order for a patient to qualify to use an IDEO, what must they accomplish first?
– why?
adopt non-rearfoot running foot strike (there are rearfoot, midfoot, and forefoot patterns for running)
– decreases stride length to keep foot under themselves
running specific feet:
– C shaped is for ____ and has ____ mount
– J shaped is for ____ and has _____ mount
– endurance ; inferior
– sprints ; posterior
what is the bench alignment for a C shaped foot?
M-L = middle
1-2” of foot in front of weight line to make contact with ground
what is the bench alignment for a J shaped foot?
what is the static alignment for a running foot?
– _____ 3-5 deg
– _____ 5-7 deg
– load line _____ from toe point of contact
– vertical deflection _______
– ER
– PF
– 1-2 inches
– 1-2 inches
