<jats:title>Purpose</jats:title>
<jats:p>Surgical treatment of adolescent idiopathic scoliosis (AIS) is very complex, involves many critical decisions and modern instrumentation techniques, and offers multiple possibilities. It is known that the surgical strategy may vary strongly between surgeons for AIS cases. The goal of this study was to document, summarize, and analyse the current biomechanical relevant variabilities in the surgical treatments of individual AIS patient cases.</jats:p>

<jats:title>Methods</jats:title>
<jats:p>Eight experienced scoliosis surgeons from different hospitals were asked to plan surgeries on 12 representative patients with AIS. The surgeons were provided with radiographs during upright standing in the coronal and sagittal plane, as well as lateral bending images to the left and right. The surgeons were asked to specify the Lenke type, their surgical approach, the resection steps, the planned fusion length, and the type of implants. The data were analysed with respect to the inter-rater variability, which was quantified using the Fleiss Kappa method.</jats:p>

<jats:title>Results</jats:title>
<jats:p>In the selection of the surgical approach, the surgeons concurred most with Lenke curve types 2 (<jats:italic>κ = </jats:italic>0.88) and 4 (<jats:italic>κ = </jats:italic>0.75). The largest differences were shown at Lenke 1 (<jats:italic>κ = </jats:italic>0.39) and 5 (<jats:italic>κ = </jats:italic>0.32). Anterior approaches were selected in the majority of cases at Lenke types 5, with an average of 50%. The strongest deviation in fusion length was documented at Lenke curve type 6.</jats:p>

<jats:title>Conclusion</jats:title>
<jats:p>The survey highlighted differences in the surgical strategy depending on the Lenke curve type, the direction of the surgical approach, and the surgeon. The main discrepancies between the surgeons were found for Lenke 1, 5, and 6 curves, and consistencies for Lenke 2, 3, and 4. The documented discrepancies indicate the remaining open questions in the surgical treatment and understanding of scoliosis biomechanics.</jats:p>
