The authors designed this randomized controlled trial to validate the efficacy of intraoperative halo-femoral traction (IOHFT) in patients with adolescent idiopathic scoliosis (AIS), Cobb angles between 70\u00b0 and 100\u00b0, and flexibility &lt; 35%.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>The authors prospectively recruited and randomized 29 patients with severe AIS scheduled for posterior surgery into a traction group or control (nontraction) group. The primary outcome measures were operative time, blood loss, and length of hospital stay. Secondary outcomes included degree of spine deformity correction, traction-related complications, and health-related quality of life.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>In the traction group, the average preoperative Cobb angle was 83.2\u00b0, with an average 20.6% flexibility. The average postoperative Cobb angle was 16.1\u00b0 and the major curve was 18.3\u00b0 at the final follow-up. In the control group, the average preoperative major curve was 80.3\u00b0 with 22.8% flexibility. The average postoperative Cobb angle was 16.1\u00b0 and the major curve was 18.1\u00b0 at the final follow-up. The operative duration was 325.7 minutes for the traction group and 385.4 minutes for the control group (p = 0.018). Compared with the control group, the traction group had a 29.5% reduction in intraoperative blood loss and a significantly lower rate of blood transfusion (13.3% vs 50.0%, p = 0.033). There were no neurological complications in either group. One patient in the traction group had a superficial infection at the traction site.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Use of IOHFT contributed to significant reductions in operative time and blood transfusion requirements, with no added morbidity.
