Résumé

PURPOSE: Preoperative preparation with halo gravity traction (HGT) has several advantages but is still controversial. A multicenter, observational, retrospective study was conducted to determine whether HGT provides better frontal correction in surgery for adolescent idiopathic scoliosis (AIS). METHODS: Between 2010 and 2020, all patients who underwent posterior spinal fusion (PSF) AIS with a Cobb angle greater than 80° were included. The included patients who underwent HGT were compared (complications rate and radiographic parameters) to patients who did not undergo traction (noHGT). For patients who underwent HGT, a spinal front X-ray at the end of the traction procedure was performed. RESULTS: Sixty-four in noHGT and forty-seven in HGT group were analyzed with a 31-month mean follow-up. The mean ratio of Cobb angle correction was 58.8% in noHGT and 63.6% in HGT group (p = 0.023). In HGT, this ratio reached 9% if the traction lasted longer than 30 days (p = 0.009). The complication rate was 11.7% with a rate of 6.2% in noHGT and 19.1% in HGT group (p = 0.07). In patient whose preoperative Cobb angle was greater than 90°, the mean ratio of Cobb angle correction increases to 6.7% (p = 0.035) and the complications rate increased to 14% in the no HGT group and decreased to 13% in the HGT group (p = 0.9). CONCLUSION: HGT preparation in the management of correction of AIS with a Cobb angle greater than 90° is a technique providing a greater frontal correction gain with similar complication rate than PSF correction alone. We recommend a minimum halo duration of 4 weeks.
