Which traction uses foam instead of plaster and is indicated for post-poliomyelitis with residual paralysis of the hip and knee?

• A. Modified Buck's Extension Traction
• B. Head Halter Traction
• C. Pelvic Girdle Traction
• D. Bohler Braun Splint

Answer: (A)

In post-polio with residual paralysis of the hip and knee, the goal is to keep the limb in extension while protecting the skin and allowing gentle, adjustable traction. The Modified Buck's extension traction does this with a foam-lined boot instead of plaster, so the traction force is transmitted along the leg while cushioning the limb. The foam reduces pressure points, improves comfort, and makes it easier to monitor skin and adjust the traction as needed, all while maintaining extension at both joints to prevent flexion contractures and support rehabilitation.

The other options don’t fit this scenario because they target different regions or use different methods: a head halter applies traction to the neck, not the hip or knee; pelvic girdle traction focuses on pelvic mechanics and often uses traditional materials rather than foam; and the Bohler–Braun splint is a splint/traction setup used for other limb injuries and isn’t the foam-based method described for post-polio hip–knee management.
