Background: The currently accepted treatment of scoliosis are bracing and surgery. Two-stage anterior and posterior spinal fusion is used to correct scoliosis. It seems that the application of a longitudinal force to the axis of the spinal column as a means of stabilizing by halo traction, may increase the correction of the curve. The aim of this study was to evaluate the effect of halo traction used between the two stages of corrective surgery, anterior and posterior spinal fusion, on the correction of scoliosis curvature.
Methods: In this randomized clinical trial twelve scoliotic patients, aged from 12-19 years old, were treated by two-stage anterior spinal release and fusion (ASF) and posterior spinal fusion (PSF). The patients were divided in two groups: 6 scoliotic patients without any traction between ASF and PSF surgeries (group A), and 6 scoliotic patients were undergone halo traction for one week between ASF and PSF surgeries (group B). Major curve angle was measured before surgery, one week after ASF and one year after PSF surgeries. Data were collected and analyzed using SPSS v.13.5.
Results: The mean baseline curve angles were 90° (SD=18.70) and 94.17°(SD=28.18) in groups A and B, respectively. Whereas, the mean final curve angles (one year after PSF) were 51.17°(SD=29.59) and 39.17°(23.11) in groups A and B, respectively. Final angle improvement was 46.58% (SD=20.31) in patients without traction and 61.32% (SD=14.02) in patients with halo traction. The major curve angles showed significantly better correction in patients with traction one week after ASF [38.67°(SD=7.86) vs. 25°(SD=6.28), P=0.012]. This difference persisted at the end of the first year after operation. [55°(SD=8.94) vs. 38.83°(SD=11.65), P=0.022].
Conclusion: Application of halo traction between ASF and PSF surgeries may lead to better improvement of the scoliotic curvature and short time application of halo traction decreases possible complications.
