reconstruction that performs a bone bridge between what:
A) Tibia bridged with the fibula
B) Distal end of the radius and ulna
C) Distal end of femur bridged with the tibia
D) Humerus bridged with the ulna Correct Ans - A) Tibia bridged with
the fibula

states he feels anterior/distal discomfort in his prosthetic socket. Choose all
correct answer(s) to address this problem:
A) Extend the prosthetic socket
B) Flex the prosthetic socket
C) Add pretibial pads to the prosthetic socket
D) Lower the posterior socket brim Correct Ans - A) Extend the
prosthetic socket
C) Add pretibial pads to the prosthetic socket
A below knee amputee is seen in your clinic for a follow up appointment and
states he has posterior knee or hamstring discomfort. Choose all correct
answer(s) to address this problem:
A) Lower the posterior medial brim on the prosthetic socket
B) Extend the prosthetic socket
C) Flex the prosthetic socket
D) Align prosthetic foot more posterior in relation to the prosthetic socket
Correct Ans - A) Lower the posterior medial brim on the prosthetic socket
C) Flex the prosthetic socket
D) Align prosthetic foot more posterior in relation to the prosthetic socket
Which level(s) of amputation may lead to an equinus gait deformity:
A) Lisfranc amputation
B) Chopart amputation
C) Symes amputation
D) Transmetatarsal amputation Correct Ans - A) Lisfranc amputation
B) Chopart amputation
D) Transmetatarsal amputation
,A below knee amputee presents in clinic wearing a PTB style endoskeletal
prosthesis with general knee pain and distal end pressure. The patient doffs
her prosthesis and liner, upon
examination of her residual limb you note redness on the distal tibia and
inferior aspect of the patella bone. What would be the most logical clinical
action(s) you could take at this point in addressing this problem:
A) Recommend the patient be evaluated for a new liner that will provide
better cushioning to her residual limb
B) Flex the prosthetic socket while concurrently plantar flexing the prosthetic
foot
C) Add a gastroc pad to prosthetic socket
D) Add a 1 ply prosthetic sock over liner Correct Ans - C) Add a gastroc
pad to prosthetic socket
D) Add a 1 ply prosthetic sock over liner
Myodesis can be described as:
A) A condition associated with calcification of muscle fibers
B) The suturing and permanent attachment of a muscle to a bone
C) The suturing or permanent attachment of a muscle to another muscle
D) A muscle going through atrophy Correct Ans - B) The suturing and
permanent attachment of a muscle to a bone
Which of the following is not part of a Symes amputation procedure:
A) Removal of the malleoli "distal aspect"
B) Placement of thick heel pad
C) Amputation through the articulation of the ankle
D) Transmetatarsal amputation Correct Ans - D) Transmetatarsal
amputation
Myoplasty can be described as:
A) A condition associated with the loss of sarcomeres
B) The suturing and permanent attachment of a muscle to a bone
C) The suturing or permanent attachment of a muscle to another muscle
D) A muscle experiencing hypertrophy Correct Ans - C) The suturing
or permanent attachment of a muscle to another muscle
What are two advantages in the list below of myodesis over myoplasty with
regards to
amputations:
, A) Decreased rate of infection related revisions
B) Decreased rate of muscular atrophy
C) Decreased rate of antagonistic muscular imbalances
D) Provides a bulbous distal residual limb for self suspending applications in
TT and TF cases Correct Ans - B) Decreased rate of muscular atrophy
C) Decreased rate of antagonistic muscular imbalances
During normal heel strike, the forward hip is how flexed:
A) neutral
B) 10 deg flexed
C) 25 deg flexed
D) 40 deg flexed Correct Ans - C) 25 deg flexed
Which style of muscular tissue management in an TH amputation would be of
greatest advantage to a myoelectric prosthesis candidate:
A) Myodesis
B) Myoplasty Correct Ans - A) Myodesis
A TF patient is seen in clinic that exhibits lateral/proximal loss of contact in
stance. Upon
prosthetic fit examination it is noted the lateral wall is superior to the greater
trochanter, the
anterior wall contours to the adductor longus tendon, the posterior socket
does not
encompass the ischial tuberosity, the medial wall is located 65mm inferior to
the perineum.
What do you attribute to the cause of this deviation:
A) The posterior wall does not have ischial containment
B) The lateral wall is located too proximal for an ischial containment socket
C) The patient is causing the deviation from antalgic gait secondary to
adductor longus
tendon socket pressure
D) The medial wall is located too far inferior to the perineum Correct Ans
- D) The medial wall is located too far inferior to the perineum
With a Krukenberg procedure what muscle is the driver of the pincer grip:
A) Supinator
B) Pronator teres
C) Brachioradialis
