Zero Degrees Traction is used for which region?

Zero Degrees Traction is used for which region?

• A. For poliomyelitis with residual paralysis
• B. Affection of the surgical neck of the humerus and the shoulder joint
• C. Subtrochanteric and proximal third fracture of the femur
• D. For S-Type scoliosis

Answer: (B)

The key idea is how the direction of traction affects alignment in different parts of the body. Zero-degree traction means the pull is directed along the long axis of the limb—in line with the bone itself. This straight-line pull is particularly suited to injuries around the shoulder girdle, where keeping the force aligned with the humerus helps seat the proximal humerus back into the glenoid and maintains stability at the shoulder joint. For fractures or injuries at the surgical neck of the humerus, a straight, in-line pull minimizes sideways or rotational forces that could worsen displacement and aids gradual realignment. Other regions require different pull directions and setups. Fractures of the femur (subtrochanteric or proximal third) often need traction paths that address weight distribution, hip position, and rotations, not just a straight line along the arm. Spinal scoliosis management uses traction objectives at the spine with specific angles and devices, not a simple zero-degree line. Poliomyelitis with residual paralysis involves different therapeutic approaches focused on muscle balance and limb function rather than a targeted shoulder-line traction.
