• A. Minerva Cast
• B. Cotrel Traction
• C. Rizzer's Cast
• D. Pelvic Girdle Traction

Answer: (B)

Traction for scoliosis works by applying gentle, gradual pulling to lengthen the spine and help reduce the curve. The Cotrel approach does this by using two traction sources at once: a head halter provides cranial traction while a pelvic girdle traction applies force at the pelvis. This combination creates longitudinal distraction along the entire spinal axis, making it more effective for initial correction and soft-tissue remodeling than a single-site traction. Other devices mentioned serve different purposes. The Minerva cast is mainly for immobilizing the cervical region, not for producing longitudinal traction through both head and pelvis. Risser’s cast is a full-body immobilization jacket used historically for scoliosis control, not the dual-source traction concept. Pelvic girdle traction alone lacks the cranial component, so it doesn’t embody the complete Cotrel method.
