Utilizing two surgeons for neuromuscular scoliosis suggests improved operative efficiency.

Abstract

Neuromuscular scoliosis (NMS) patients tend to have significant comorbidities with complex medical and surgical histories. When undergoing posterior spinal fusion (PSF), NMS risks can be much higher than the idiopathic population. This study aimed to identify the impact of two experienced pediatric cosurgeons (CS) compared to a single spine surgeon (SS) on the intra- and postoperative results of NMS PSF. A database of NMS patients who had undergone PSF 2016-2021 identified 53 patients, of which 32 were CS, while 21 were SS. Patients' sex, age, weight, diagnosis, curve severity, fusion performed, estimated blood loss (EBL), transfusion rates, hemoglobin, anesthesia and surgical times, length of stay, and complications were collected. Patient demographics were similar between groups. Curves were more severe in the CS group (p = 0.013). Intraoperatively, CS patients underwent larger corrections (p = 0.089) but in significantly shorter anesthetic (p = 0.0018) and operative (p = 0.0025) times. Blood loss and transfusions were similar. Postoperatively, intensive-care unit (ICU) admission and length of stay (LOS) were similar, but SS had higher rates of both unplanned ICU admissions (p = 0.36) and 30day readmissions (p = 0.053). Complications overall were similar between the groups both within 30days (p = 0.40) and in the short-term period (31-90days, p = 0.76), though the CS cohort had less Grade 2 immediate postoperative pulmonary complications (p = 0.16). Utilizing CS for NMS PSF has been found to reduce operative times. Downstream, additional potential impacts trended toward fewer unplanned ICU admissions, less-frequent postoperative pulmonary complications, and reduced 30-day readmission rates.
