Halo gravity traction for pediatric scoliosis and kyphoscoliosis: A review of current evidence and best practices

Figure 1 Illustration of the biomechanical principle of halo gravity traction. A: Depicting a schematic of the sagittal view of a patient on halo traction, where a vertically oriented traction force is applied to the skull and connected to an overhead pulley system. External weight applied through the pulley pulls the spine against gravity; B: Depicting a schematic of the frontal view of a patient demonstrating that the traction is in line with the center of the head and spine.
