Which practice is encouraged for transtibial amputation positioning?

• A. Prolonged elevation of the residual limb
• B. Periodic prone lying
• C. Never lie prone
• D. Encourage continuous side-lying

Answer: (B)

Periodic prone lying helps prevent contractures by allowing the residual limb to extend fully. When you lie prone, the hip flexors are gently stretched and the knee tends toward extension, which reduces the risk of knee flexion and hip flexion contractures that can interfere with future prosthetic fitting and gait. Prolonged elevation of the residual limb or staying in side-lying can promote soft-tissue shortening and contractures and do not provide the same opportunity to maintain extension, so they are less favorable for transtibial amputation positioning.
