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

Figure 2 An illustrative example of severe scoliosis corrected with a staged procedure-halo gravity traction followed by posterior instrumentation and fusion. A: Clinical picture of a 9-year-old boy, previously operated for diastematomyelia with severe thoracolumbar scoliosis with a decompensated curve; B: Clinical picture after application of halo gravity traction for 6 weeks and application of growing rods; C: Preoperative radiograph demonstrating scoliotic curve with a Cobb angle of 114°; D: Radiograph immediately before spinal instrumentation showing a Cobb angle of 76° (38° correction after halo gravity traction for 6 weeks); E: Postoperative radiograph with Cobb angle of 66 degrees after growing rod application.
