USA - Prosthetics - Exam 2

Which amputation is described as "Excision of any part of one or more toes."?

A prosthesis is not necessary for toe amputations.

Which amputation is described as "Disarticulation at the metatarsalphalgeal joint."?

1st digit amputation results in severe hallux valgus/ lateral deviation

Phalangeal amputation actually refers to a partial toe amputation, not necessarily a full toe disarticulation.

There are no toe prosthetics because toe amputations do not require prosthetics.

Which amputation is described as "Amputation through the mid-section of all metatarsals."?

Which amputation is described as "A disarticulation through the midtarsal joint leaving only the calcaneus and talus."?

Limb length discrepancy may be a problem in which of the following amputations?

Which of the following are Rigid or Semi-Rigid prosthetics?

Which of the following are Flexible or Semi-Flexible prosthetics?

Which of the following may incorporate a patellar-tendon-bearing (PTB) design to reduce weight bearing to the foot?

Which of the following is used with patients with equines deformity that can be passively corrected? A plate supports the residual foot and attaches to a shank piece which is formed around the calf.

Which of the following is a simple foam filler with plastic insert for transverse arch and rear foot stability.

In which of the following prosthetses are semi-flexible urethane elastomers modeled to provide a foot-shape prosthesis with a soft socket that conforms to the foot.

Which of the following is a life-like foot designed of soft, flexible mold silicone which is cosmetically appealing and functional?

Which of the following is made from carbon fiber composite materials and has a footplate that offers flexibility, creating a more responsive prosthesis?

How much of the tibial length remains in a Long Transtibial Amputation?

How much of the tibial length remains in a Conventional Transtibial Amputation?

How tibial length remains in a Short Transtibial Amputation?

What are the advantages & disadvantages of a Trans-Tibial amputation relative to a Trans-Femoral amputation?

Which of the following feet are appropriate for a typical patient at K1?

Which of the following feet are appropriate for a typical patient at K2?

Which of the following feet are appropriate for a typical patient at K3?

Which of the following feet are appropriate for a typical patient at K4?

What type of foot is this and to which K-Level does it belong?

What type of foot is this and to which K-Level does it belong?

What type of foot are these and to which K-Level do they belong?

What type of foot is this and to which K-Level does it belong?

What type of foot is this and to which K-Level does it belong?

What type of foot is this and to which K-Level does it belong?

Walking in sand requires which of the following accessories?

How much of the femoral length remains in a Long Transfemoral Amputation?

How much of the femoral length remains in a Standard Transfemoral Amputation?

How much of the femoral length remains in a Short Transfemoral Amputation?

What are the advantages of a transfemoral amputation relative to the more distal amputations?

The quadrilateral socket for a transfemoral amputation allows for muscle contractions.

The Quadrilateral socket (TFA) is characterized by reliefs and bulges.

The Ischial Containment Socket is characterized by narrow medial / lateral diameter with greater width in the anterior / posterior dimensions

The Quadrilateral Socket (TFA) is characterized by narrow medial / lateral diameter with greater width in the anterior / posterior dimensions.

The Ischial Containment socket (TFA) is characterized by reliefs and bulges.

Stability of a Knee Unit is accomplished by which of the following?

Swing Control of a Knee Unit is accomplished by which of the following?

Which of the following Swing-Phase Control Mechanisms are appropriate for K1 and K2?

Which of the following Swing-Phase Control Mechanisms are appropriate for K3 and K4?

C-Leg and Genium are which type of Swing-Phase Control Mechanisms?

The Weight-Activated Stance Brake Knee (WASB) imparts a characteristic gait deviation and limits cadence to a single speed.

The Weight-Activated Stance Brake Knee (WASB) imparts a characteristic gait deviation, but is otherwise appropriate for K3.

Which Hip Joint Mechanism is described below? At toe off, knee flexion pulls the hip joint against the posterior extension stop. As the knee rotates forward the weight and slight pelvic posterior rotation flexes the hip. Because the prosthesis is at full length during mid swing the prosthesis must be significantly shortened to permit toe clearance, however, most amputees tend to vault with the contralateral leg.

Which Hip Joint Mechanism is described below? As weight passes over the prosthesis during stance the coiled spring is compressed. At toe off the spring is released.

Which Hip Joint Mechanism is described below? A carbon fiber strut is fabricated to the anterior portion of the socket. Weight bearing during stance compressed the strut and as the body weight is reduced going into swing the prosthetic thigh is deflected forward. No additional pelvic motion is required.
