OBJECTIVE: To determine the postoperative changes produced in coronal balance of patients with adolescent idiopathic scoliosis (AIS) and Lenke type 5 curves, carrying out a pre- and postoperative analysis of the following radiological parameters: last arthrodesed vertebral level, L4 tilt, translation of the apical vertebra, lumbosacral obliquity, Cobb angle, and previous coronal balance. METHODS: 20 patients with a diagnosis of AIS with Lenke type 5 curves, in mean follow-up of 36 months (Range: 24 to 48), were evaluated. The mean age at surgery was 15.3 years (Range: 13 to 20 years), and the distribution by sex was 16 women and 4 men. RESULTS: In our series, we found a direct correlation between AVTL and LSTOA, and postoperative coronal balance, both in the group of patients that improved (14 patients) and in those with worsening of coronal balance (6 patients). CONCLUSION: in the case series evaluated, AVTL and LSTOA were the specific radiographic parameters.
