Study DesignRetrospective, chart review.ObjectivesThe objective of this study is to investigate the impact of using two surgeons for posterior spinal fusion (PSF) in patients with AIS with large-magnitude curves (greater than 70°).Summary of Background DataPrevious studies have shown that intraoperative risk factors can be reduced by having two surgeons operate simultaneously.MethodsA retrospective chart review identified 47 patients between January 1, 2009, and December 31, 2014, who underwent a posterior spinal fusion (PSF) with AIS with large-magnitude curves (greater than 70°). Patients with large-magnitude curves due to neuromuscular diseases or any defined pathology other than idiopathic scoliosis were excluded, as well as patients with kyphotic or kyphoscoliotic curves.ResultsThere was no statistical difference between the total operative time, anesthesia time, estimated blood loss (EBL), %EBL, and blood transfusion units. Total operative time for the two-surgeon group and single-surgeon group was 212.11 and 238.07 minutes, respectively (p = .078). The two-surgeon group averaged 0.26 blood transfusion units versus 0.39 units for the single-surgeon group (p = .50). Average hospital length of stay was decreased in the two-surgeon group (5.16 vs. 6.82 days, p = .002).ConclusionsThe use of two surgeons for PSF for AIS has previously been shown to decrease operative time and blood loss, factors that are correlated with prolonged hospital stay and increased risk of both neurologic and nonneurologic complications. However, in this study, the technique of having two experienced orthopedic spine surgeons work simultaneously to perform pedicle screw–only posterior spinal fusion on large-magnitude AIS curves greater than 70° did not improve blood loss or operative time. Further study needs to continue to identify ways to minimize complications for patients who undergo spinal fusion.Level of EvidenceLevel III, retrospective, comparative study.
