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

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."?

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?

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?

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

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.
