  1. How should a transfemoral socket be aligned for a patient with a 10-degree hip flexion contracture?

    Answer: Add initial socket flexion equal to the contracture plus about 5 degrees

    Preflexing the socket beyond the contracture accommodates it, avoids excessive lumbar lordosis, and lets the hip extensors work.

  2. A transtibial prosthesis user shows excessive knee flexion immediately after heel strike. Which is a likely cause?

    Answer: Heel cushion too firm

    A firm heel cannot compress at loading, so the floor reaction force moves posterior to the knee and drives it rapidly into flexion.

  3. When a transfemoral prosthesis user's heel moves medially at toe-off (medial whip), what is a common cause?

    Answer: Knee axis externally rotated

    An externally rotated knee bolt causes the heel to whip medially when the knee flexes at toe-off.

  4. A patient with hemiplegia hyperextends the knee in stance because of plantarflexor spasticity. Which AFO modification best addresses this?

    Answer: Ankle set in slight dorsiflexion to create a knee flexion moment

    Setting the AFO in slight dorsiflexion moves the ground reaction force anterior to the ankle and posterior to the knee, reducing genu recurvatum.

  5. A Jewett hyperextension orthosis is most appropriate for which condition?

    Answer: Stable anterior compression fracture at the thoracolumbar junction

    The Jewett uses three-point pressure to limit flexion and is suited to stable anterior compression fractures around T10-L2.

  6. After a new socket is delivered, how long can skin redness persist after removal before it signals excessive pressure?

    Answer: More than about 20-30 minutes

    Reactive hyperemia should fade within roughly 20-30 minutes, and redness that lasts longer points to excessive pressure that needs modification.

  7. What is the generally optimal age to begin cranial remolding orthosis treatment for deformational plagiocephaly?

    Answer: About 4-6 months

    Starting around 4-6 months takes advantage of rapid skull growth and gives the best correction in the shortest time.
