Q

In general, what is the most common type of amputation seen among new amputees?

A) Transfemoral
B) Syme’s
C) Transtibial
D) Hip disarticulation

A

C) Transtibial

The most common type of amputation is a transtibial or below knee amputation (BKA). Transfemoral or above knee amputations are approximately half as common as BKA, whereas Syme’s (ankle disarticulation) and hip disarticulation are very uncommon.

Q

In a standard transtibial amputation, the amputation is approximately what percentage of the tibial length?

A) < 20
B) 20 to 50
C) > 50
D) > 75

A

B) 20 to 50

A standard transtibial amputation is 20% to 50% of the tibial length. A long transtibial is > 50% of the tibial length, whereas a short transtibial amputation is < 20% of the tibial length

Q

Which of the following would be acceptable in contracture prevention for the transtibial amputee?

A) Sitting with the knee extended on a towel-wrapped board under the wheelchair cushion
B) Sitting with the residual limb hanging over the edge of the bed

Q

Which of the following prosthetic foot is the most affordable?

A) Multiaxis foot
B) Solid ankle cushion heel (SACH)
C) Energy storing
D) Single-axis foot

A

B) Solid ankle cushion heel (SACH)

The single-axis foot permits movement of the foot-ankle complex in the plantar flexion/dorsifl exion axis, whereas the multiaxis foot allows some controlled movement in the normal anatomic planes (plantar flexion, dorsiflexion, inversion, eversion, and rotation).

Q

Brawny edema, induration, and discoloration of the skin of the distal stump in a circular shape may indicate which dermatologic complication in an amputee?

A) Allergic dermatitis
B) Epidermoid cyst
C) Folliculitis
D) Choked stump syndrome

A

D) Choked stump syndrome

This may result when the residual limb becomes too large to fi t properly in the total contact socket. The socket will become too tight proximally and therefore obstruct venous outfl ow. An edematous distal residual limb will result. Folliculitis, cysts, and dermatitis are all potential complications of a prosthesis, yet do not result in edema and induration.

Q

Which dermatologic complication results from inadequate socket wall contact with subsequent edema formation causing wart-like skin overgrowth?

A) Tinea corporis
B) Verrucous hyperplasia
C) Hyperhidrosis
D) Folliculitis

A

B) Verrucous hyperplasia

Tinea corporis mainly results from sweating and can be prevented and treated with good socket hygiene and antifungal medications. Hyperhidrosis
may cause maceration of the skin, which predisposes the skin to infection. Folliculitis is
an infection of the hair root resulting from poor hygiene, sweating, and either pistoning
or poor socket fi t.
