OBJECTIVE: To determine the outcome of lumbar segment without arthrodesis in the coronal plane, after selective thoracic fusions for with curvature of Lenke type 1 adolescent idiopathic scoliosis with curvature of Lenke type 1. METHODS: Twenty one patients were evaluated, with a mean follow-up of 29.71 months (range: 24-60 months) with retrospective clinical and radiographic analysis of patients with adolescent idiopathic scoliosis with curvature of Lenke type 1 (ABC). RESULTS: The increase of the angle of the lumbar curve without fusion was documented at the end of the follow-up in patients with coronal plane imbalance. CONCLUSION: Lumbar curve without fusion progressed at the end of the follow-up in patients with documented coronal plane imbalance (3/21).
