Which traction is used for S-Type scoliosis?

• A. Halo-Pelvic Traction
• B. Halo-Femoral Traction
• C. Bryant Traction
• D. Boot Cast Traction

Answer: (B)

Traction for scoliosis aims to slowly realign the spine by applying a steady pull along its length using skeletal anchors. For an S-shaped curve, where two curves interact to form a single, longer deformity, you want a setup that can pull the spine from both ends with good control. Halo-femoral traction uses a halo ring fixed to the skull and a traction point in the femur, with a device between them that applies a long, continuous pull along the spine. This configuration lets the spine be gradually guided toward midline, correcting both curves in a coordinated way as the traction is increased over time. It provides effective, controlled correction and is less invasive than halo-pelvic traction, which is reserved for more severe, rigid curves. Other forms, like Bryant traction, are typically used in very young children for different indications, and boot cast traction is not used for scoliosis.
