Question 1

In a patellar-tendon-bearing transtibial socket, which area is pressure-sensitive and typically requires relief?

Accepted Answer

Fibular head

Answer

The fibular head is a bony prominence over the peroneal nerve and must be relieved, while the other areas tolerate load or provide counterpressure.

Question 2

A transtibial prosthesis user reports distal-end pain and a sense of sinking into the socket late in the day. What is the most appropriate first intervention?

Accepted Answer

Add sock ply to compensate for limb volume loss

Answer

Daily residual limb volume loss lets the limb bottom out, and adding socks restores fit.

Question 3

A transfemoral prosthesis user shows lateral trunk lean toward the prosthetic side during stance. Which socket-related cause is most likely?

Accepted Answer

Inadequate lateral wall adduction support

Answer

Without adequate lateral wall support holding the femur in adduction, the hip abductors cannot stabilize the pelvis, so the trunk leans over the prosthesis.

Question 4

What is the preferred initial orthotic management for active (fragmentation-stage) Charcot neuroarthropathy of the midfoot?

Accepted Answer

Total contact cast or CROW walker

Answer

During the active phase the foot must be immobilized and offloaded with a total contact cast or CROW to prevent progressive collapse.

Question 5

A patient has isolated foot drop from common peroneal nerve palsy, with intact sensation, good mediolateral ankle stability, and no spasticity. Which orthosis is most appropriate?

Accepted Answer

Posterior leaf spring AFO

Answer

A posterior leaf spring AFO provides swing-phase dorsiflexion assist for isolated dorsiflexor weakness without restricting the rest of the gait.
