Ninety-Ninety Degrees Traction is indicated for?

• A. Subtrochanteric and proximal third fracture of the femur
• B. Affection of the surgical neck of the humerus and the shoulder joint
• C. For C type scoliosis
• D. Affection of the hip and femur

Answer: (A)

Ninety-Ninety Degrees Traction uses two pulls with the limb held at 90 degrees at the hip and knee to apply an axial, balanced force along the femur. This setup counteracts the strong muscle forces that tend to flex, shorten, or rotate the proximal fragment in subtrochanteric and proximal femur fractures, while allowing the distal fragment to stay aligned. By maintaining the limb in this position, it helps preserve leg length, reduce deforming forces, and provide pain relief through muscle relaxation, facilitating gradual reduction and preparation for definitive treatment. That combination of aligning the fracture with controlled, steady traction makes it particularly suited for subtrochanteric and proximal third fractures of the femur.
