Q

what sis vaulting

A

Q

what is pistoning 2/2

Study These Flashcards
A

inadquate suspension

and can result in distal residual limb issues

25
what is a polycentric knee
a knee joint that has multiple axes of rotation this allows for a more nautral gait cycle in comparison to a single axis knee
26
what is a pylon
pipe like structure used to connect the socket of the prothesis to foot/ankle the shank
27
what does the pylon help with
shock absorption and weight distribution
28
what is the residual limb
the limb left after amp
29
what is a rotionalplasty
a portion of the limb is removed while the remaining limb below is rotated and reattached think of the foot/ankle as a knee joint
30
what is a rotionalplasty normally performed for
distal femoral osteosarcoma
31
what is osteosarcoma
a type of bone cancer often starts in the long bones
32
what is a shrinker
an elastic sleeve that is placed over the end of a residual limb to control edema and promote limb shapping
33
what is stance control (safety)
a weight activated mechanism maintain knee ext during stance even if the knee is not fully extended when the knee is flexed more then the mechanism is made for the knee the mech will not engage
34
what is suspension
used to decribe how the socket is attached to the resisdual limb
35
what are common types of suspension
vacuum shuttle shock suction waist belt harness
36
where should be the area of primary weight bearing ain a transtibial prothesis
patellar tendon
37
is it possible to bear weight through the end of a transfemoral disarticulation
no - knee disarticualtion
38
what is the most common level of UE amp
transradial
39
what is a uncommon amp due to disadvantages
wrist disarticulation
40
what is the most common cause of transhumeral injury
trauma
41
what is lisfranc
disarticulation of the metatarsal or tarsal
42
what is the least likely cause of LE amp
congential limb issue 5%
43
what are the most common causes of LE amp
diabetes Peri vascular disease severe infection
44
what are the most common cause of UE amp
trauma Approximately 85% of all upper limb amputations result from trauma
45
what is a ray resection
defined as the removal of a toe and all or part of the corresponding metatarsa
46
what type of ray resection is the hardest to deal with
1st ray
47
with hip disarticulation what mobility devices would the patient use
patient is most likely to forgo a prosthesis and opt for crutches for mobility following a hip disarticulation. Many individuals find ambulation with a prosthesis at this level extremely challenging due to the high energy requirements of controlling three prosthetic joints.
48
what is a long transtibial amputation
distal third of the lower extremity below the knee joint
49
short transtibial amputation amp
refers to the surgical removal of the limb at the proximal third of the tibia.
50
excessive knee flexion during stance phase
If the prosthetic foot is aligned into excessive dorsiflexion, there is potential for knee instability (buckling) during the loading response.
51
what is the most important factor in determine whether someone is a candidate for a pro
prior level of function
52
what is a unna boot
a compression bandage An Unna boot has a special medicine in the gauze that will help heal burns or skin sores and protect new skin.
53
what is the primary purpose of using a rigid dressing
They are primarily used for residual limb protection and edema contro a plyon can also be attached for early amb
54
what must be removed to wear an Elastic shrinkers
Due to the possible stress on the incision site, elastic shrinkers are not recommended until the sutures have been removed from the amputation site.
55
what are elelastic shrinker used for
edema control and residual limb shaping
56
wrapping the residual limb of a patient who has had a transtibial amputation what size of bandage should be used
2 4 inch bands they should be wrapped in a figure 8 for limb shaping
57
What is the primary area of the residual limb that is used for weight bearing in a transtibial knee prosthesis?
patella tendon A patellar tendon bearing socket is the most common type of socket used by a patient with a transtibial amputation
58
less tolerant - transtibial
distal end of the tibia, tibial tuberosity, and fibular head.
