Adolescent idiopathic scoliosis (AIS) is a complex 3-dimensional deformity. Previous studies have suggested a learning curve in the successful execution of this technically demanding procedure. A 2-surgeon model may be helpful for less experienced surgeons by facilitating greater consistency in surgical metrics. The objective of this study was to show no significant difference in the parameters examined for surgeries done by inexperienced primary surgeons with a 2-surgeon model compared with those done by their more experienced cohorts. All surgeries with a primary diagnosis of AIS that were performed from January 2012 to December 2015 and had a minimum of 2-year follow-up were included for analysis. Three groups were created based on surgeon experience: inexperienced surgeons (IS) group, experienced surgeons (ES) group, and a third group where the primary surgeon was in the experienced group and the assistant surgeon was in the inexperienced group (EIS). Variables included for analysis were age, Lenke classification, number of levels fused, length of surgery, length of stay, percent curve correction, ratio of estimated blood loss to levels fused, surgical blood loss, and complications. There were no significant differences between the groups in terms of operative time, blood loss, number of levels fused, lower estimated blood loss ratio to the number of levels fused, or percent curve correction ( P >.05). The IS group was found to have a significant shorter length of stay ( P =.004). The 2-surgeon model is an effective tool for inexperienced surgeons to achieve consistent and reproducible operative performance that is comparable with their more experienced peers.
